Question

A company has a large on-premises Tape backup solution. The company has started to use AWS Storage Gateway. The company created a Tape Gateway to replace the existing on-premises hardware. The company’s backup engineer noticed that some of the backup jobs that were supposed to write to AWS failed to run because of a “Not Enough Space” error.

The company does not want these failures to happen again. The company also wants to consistently have enough tape available on AWS.

What is the MOST operationally efficient way for a SysOps administrator to meet these requirements?

A. Create an AWS Lambda function that runs on an hourly basis and checks how many Tapes have available space. If the available tapes are below a certain threshold, provision more.
B. Install the Amazon CloudWatch agent on the on-premises system. Push the log files to a CloudWatch log group. Create an AWS Lambda function that creates more tapes when the “Not Enough Space” error appears. Create a metric filter and a metric alarm that launches the Lambda function.
C. Create an additional Tape Gateway with its own set of tapes. Configure Amazon Simple Notification Service (Amazon SNS) to send a notification to the backup engineer if the tapes that are associated with the primary Tape Gateway do not have available space.
D. Configure tape auto-create on the Tape Gateway. In the auto-create settings, configure a minimum number of tapes, an appropriate barcode prefix, and a tape pool.

Answer

D. Configure tape auto-create on the Tape Gateway. In the auto-create settings, configure a minimum number of tapes, an appropriate barcode prefix, and a tape pool.

Explanation 1

Option D. Configure tape auto-create on the Tape Gateway. In the auto-create settings, configure a minimum number of tapes, an appropriate barcode prefix, and a tape pool – is the MOST operationally efficient way for a SysOps administrator to meet these requirements.

Tape auto-create on the AWS Storage Gateway’s Tape Gateway allows you to automatically create tapes on demand to match your organization’s needs, thus ensuring that there is enough tape available on AWS. You can configure tape auto-create to ensure a specified minimum quantity of available tapes in your virtual tape library (VTL), and when the quantity of available tapes falls below this minimum, Tape Gateway auto-creates tapes according to your settings. Essentially, this solution helps the company maintain a consistent supply of tapes without manual intervention or complex scripting, reducing the risk of encountering “Not Enough Space” errors. This option is operationally efficient, cost-effective, and demand-driven, thus meeting the objective outlined in the problem statement.

Explanation 2

The MOST operationally efficient way for a SysOps administrator to meet these requirements is to configure tape auto-create on the Tape Gateway. In the auto-create settings, configure a minimum number of tapes, an appropriate barcode prefix, and a tape pool.

Option A is not as efficient because it requires the creation of an AWS Lambda function. Additionally, this option would require the Lambda function to run on an hourly basis to check how many tapes have available space and provision more if necessary. This could add latency and overhead.

Option B is also not as efficient as Option D because it requires the installation of the Amazon CloudWatch agent on the on-premises system and the creation of a metric filter and a metric alarm to launch the Lambda function. Additionally, this option would require the Lambda function to be constantly running, which could add latency and overhead.

Option C is not as efficient as Option D because it requires the creation of an additional Tape Gateway with its own set of tapes. This option would also require the configuration of Amazon Simple Notification Service (Amazon SNS) to send a notification to the backup engineer if the tapes that are associated with the primary Tape Gateway do not have available space. This could add complexity and cost.

Option D is the most efficient solution because it is a built-in feature of AWS Storage Gateway. To configure tape auto-create on the Tape Gateway, follow these steps:

1. Open the AWS Storage Gateway console.
2. Click Gateways.
3. Click the Tape Gateway that you want to configure tape auto-create for.
4. Click Actions and then click Configure tape auto-create.
5. In the Tape auto-create settings section, configure the following:
   • Minimum number of tapes: This is the minimum number of tapes that should be available on the Tape Gateway at all times.
   • Barcode prefix: This is a prefix that will be used to generate the barcodes for the new tapes.
   • Tape pool: This is the tape pool that the new tapes will be assigned to.
6. Click Save.

Once tape auto-create is configured, AWS Storage Gateway will automatically create new tapes when the number of available tapes falls below the minimum number that you specified. This will help to ensure that there are always enough tapes available for your backup jobs.

Additional benefits of using tape auto-create:

• Tape auto-create is a fully managed feature, so you don’t need to worry about managing the infrastructure required to create and manage new tapes.
• Tape auto-create is highly scalable, so it can handle large numbers of tapes efficiently.
• Tape auto-create can help to reduce the risk of backup job failures due to lack of available tapes.

Overall, configuring tape auto-create on the Tape Gateway is the most operationally efficient way for a SysOps administrator to ensure that there are always enough tapes available for backup jobs.

Explanation 3

The most operationally efficient way for a SysOps administrator to meet the requirements of preventing backup failures due to “Not Enough Space” errors and consistently having enough tape available on AWS is option D: Configure tape auto-create on the Tape Gateway, specifying a minimum number of tapes, an appropriate barcode prefix, and a tape pool.

Here’s a detailed explanation of why option D is the best choice:

1. AWS Storage Gateway: AWS Storage Gateway provides a hybrid cloud storage solution, enabling seamless integration between on-premises environments and AWS cloud storage services.
2. Replacing on-premises tape backup: The company has created a Tape Gateway to replace the existing on-premises tape backup solution. This allows them to leverage AWS’s scalable and durable storage infrastructure.
3. “Not Enough Space” error: The backup engineer noticed that some backup jobs failed to run due to a “Not Enough Space” error. This indicates that the available tape storage on AWS was insufficient to accommodate the backup data.
4. Preventing failures: Option D suggests configuring tape auto-create on the Tape Gateway. By enabling tape auto-create, the Tape Gateway will automatically create new tapes as needed, based on the specified configuration settings.
5. Configuring minimum number of tapes: By setting a minimum number of tapes in the auto-create settings, the administrator ensures that there are always a sufficient number of tapes available for backup operations. This helps prevent failures due to lack of space.
6. Appropriate barcode prefix and tape pool: The administrator can configure an appropriate barcode prefix and tape pool for the auto-created tapes. This allows for better organization and management of the tapes, ensuring that they are dedicated to backup operations.
7. Operational efficiency: Option D provides an operationally efficient solution. With tape auto-create, the administrator does not need to manually provision additional tapes or monitor the available space. The Tape Gateway takes care of creating new tapes as required, ensuring a seamless backup process.
8. No additional services or monitoring: Option D does not require the setup of additional services like AWS Lambda or Amazon SNS. It simplifies the solution by leveraging the capabilities of the Tape Gateway itself.

In summary, option D – configuring tape auto-create on the Tape Gateway, specifying a minimum number of tapes, an appropriate barcode prefix, and a tape pool – is the most operationally efficient way to prevent backup failures due to space constraints and consistently maintain enough tape availability on AWS.

Explanation 4

The correct answer is D. Configure tape auto-create on the Tape Gateway. In the auto-create settings, configure a minimum number of tapes, an appropriate barcode prefix, and a tape pool.

Here is an explanation:

• AWS Storage Gateway is a service that enables you to connect your on-premises applications with AWS cloud storage. It can help you reduce your storage costs, improve your backup and recovery processes, and simplify your data management.
• AWS Storage Gateway offers three types of gateways: File Gateway, Volume Gateway, and Tape Gateway. Tape Gateway enables you to replace your physical tape infrastructure with a virtual tape library (VTL) that stores your tape backups on Amazon S3 or Amazon S3 Glacier.
• Tape Gateway supports tape auto-create, which is a feature that automatically creates new tapes in your VTL when the existing tapes are full or unavailable. You can configure the auto-create settings to specify the minimum number of tapes that you want to have available in your VTL, the barcode prefix that you want to use for the new tapes, and the tape pool that you want to assign the new tapes to.
• By configuring tape auto-create on the Tape Gateway, you can ensure that you always have enough tape available on AWS for your backup jobs. You can also avoid the “Not Enough Space” error that occurs when your backup jobs try to write to a full or unavailable tape. This is the most operationally efficient way to meet the requirements because it does not require any additional resources or services to implement.
• The other options are not operationally efficient solutions because they involve additional steps or services that are not necessary for this requirement. For example:
  • Option A: Creating an AWS Lambda function that runs on an hourly basis and checks how many tapes have available space is not an efficient solution because it adds complexity and overhead to your solution. It also does not guarantee that you will have enough tape available at any given time, as the backup jobs may run more frequently than the Lambda function.
  • Option B: Installing the Amazon CloudWatch agent on the on-premises system and pushing the log files to a CloudWatch log group is not an efficient solution because it adds latency and bandwidth consumption to your solution. It also does not prevent the “Not Enough Space” error from occurring, as it only reacts to it after it happens.
  • Option C: Creating an additional Tape Gateway with its own set of tapes is not an efficient solution because it adds cost and redundancy to your solution. It also does not solve the problem of having enough tape available on AWS, as it only provides a backup option if the primary Tape Gateway fails.

Explanation 5

To ensure that the company consistently has enough tape available on AWS and to prevent backup job failures due to “Not Enough Space” errors, the most operationally efficient way would be to configure tape auto-create on the Tape Gateway and set a minimum number of tapes, an appropriate barcode prefix, and a tape pool. This approach leverages the power of AWS Storage Gateway to automatically create new tapes when needed, ensuring that there is always enough space available for backup jobs. By configuring a minimum number of tapes, you can ensure that the company has a consistent supply of tapes available on AWS.

Option A suggests creating an AWS Lambda function that runs on an hourly basis and checks how many tapes have available space. If the available tapes are below a certain threshold, provision more. While this approach can be effective, it requires additional setup and maintenance of the custom Lambda function.

Option B suggests installing the Amazon CloudWatch agent on the on-premises system, pushing the log files to a CloudWatch log group, creating an AWS Lambda function that creates more tapes when the “Not Enough Space” error appears, and creating a metric filter and a metric alarm that launches the Lambda function. Although this option can also achieve the desired outcome, it involves more manual configuration compared to Option D.

Option C suggests creating an additional Tape Gateway with its own set of tapes and configuring Amazon Simple Notification Service (Amazon SNS) to send a notification to the backup engineer if the tapes that are associated with the primary Tape Gateway do not have available space. While this option may work, it is not as operationally efficient as Option D.

Therefore, based on operational efficiency and ease of implementation, Option D is the recommended solution for ensuring that there is always enough tape available on AWS and preventing backup job failures due to “Not Enough Space” errors.

Explanation 6

The MOST operationally efficient way for a SysOps administrator to meet these requirements is to configure tape auto-create on the Tape Gateway.

Option A is not as efficient because it requires the creation and maintenance of an AWS Lambda function. Additionally, this option would require the Lambda function to run on an hourly basis, which could add latency and overhead.

Option B is also not as efficient as Option D because it requires the installation of the Amazon CloudWatch agent on the on-premises system and the creation of an AWS Lambda function. Additionally, this option would require the Lambda function to be invoked whenever the “Not Enough Space” error appears, which could add latency and overhead.

Option C is not as efficient as Option D because it requires the creation and maintenance of an additional Tape Gateway. Additionally, this option would require the SysOps administrator to manually configure the additional Tape Gateway and to configure Amazon SNS to send notifications when the tapes that are associated with the primary Tape Gateway do not have available space.

Option D is the most efficient solution because it is a fully managed service. AWS Storage Gateway will automatically create new virtual tapes when the minimum number of tapes that is specified in the auto-create settings is not met. This option is also the most scalable, as it can handle large volumes of data efficiently.

To configure tape auto-create on the Tape Gateway, follow these steps:

1. Open the AWS Storage Gateway console.
2. Click Gateways.
3. Select the Tape Gateway that you want to configure.
4. Click Actions.
5. Click Configure tape auto-create.
6. In the Minimum number of tapes section, specify the minimum number of tapes that you want to have available on the Tape Gateway at all times.
7. In the Barcode prefix section, specify a barcode prefix for the new tapes that are created.
8. In the Tape pool section, select the tape pool that you want to use for the new tapes.
9. Click Save.

Once tape auto-create is configured, AWS Storage Gateway will automatically create new virtual tapes when the minimum number of tapes that is specified in the auto-create settings is not met. This will ensure that the company always has enough tape available on AWS to run its backup jobs.

Additional benefits of using tape auto-create:

• Tape auto-create is a fully managed service, so the SysOps administrator does not need to worry about managing the infrastructure required to create new tapes.
• Tape auto-create is highly scalable, so it can handle large volumes of data efficiently.
• Tape auto-create can be configured to use a variety of tape pools, so the SysOps administrator can choose the tape pool that is most appropriate for the company’s needs.

Overall, configuring tape auto-create on the Tape Gateway is the most operationally efficient way for the SysOps administrator to meet the company’s requirements and ensure that it always has enough tape available on AWS to run its backup jobs.

Explanation 7

To ensure that the company’s backup jobs run smoothly and consistently, while also maintaining an adequate supply of tapes on AWS, the MOST operationally efficient approach for a SysOps administrator would be to configure tape auto-create on the Tape Gateway. This can be achieved by configuring the auto-create settings with a minimum number of tapes, an appropriate barcode prefix, and a tape pool. By doing so, the Tape Gateway will automatically create new tapes as needed, ensuring that there is always enough tape available on AWS.

Option A suggests creating an AWS Lambda function that runs on an hourly basis to check how many tapes have available space and provision more if the available tapes are below a certain threshold. While this approach can help maintain sufficient tape availability, it requires manual intervention and may not be as operationally efficient as the auto-create feature provided by the Tape Gateway.

Option B involves installing the Amazon CloudWatch agent on the on-premises system, pushing log files to a CloudWatch log group, and creating an AWS Lambda function that creates more tapes when the “Not Enough Space” error appears. While this approach can address the issue of insufficient space, it introduces additional complexity and dependencies by relying on CloudWatch logs and alarms.

Option C suggests creating an additional Tape Gateway with its own set of tapes and configuring Amazon Simple Notification Service (Amazon SNS) to send a notification to the backup engineer if the tapes associated with the primary Tape Gateway do not have available space. While this approach provides redundancy and alerts for low tape availability, it requires managing multiple Tape Gateways and may not be as operationally efficient as the auto-create feature.

Therefore, option D is the MOST operationally efficient way for a SysOps administrator to meet these requirements.

Explanation 8

The correct answer is D. Configure tape auto-create on the Tape Gateway. In the auto-create settings, configure a minimum number of tapes, an appropriate barcode prefix, and a tape pool.

Explanation:

AWS Storage Gateway is a service that enables you to connect your on-premises applications with AWS cloud storage. It provides three types of gateways: File Gateway, Volume Gateway, and Tape Gateway. Tape Gateway is a virtual tape library (VTL) that emulates physical tape drives and media changers, and allows you to store your backup data on virtual tapes in Amazon S3 or Amazon S3 Glacier.

To use Tape Gateway, you need to create a gateway and associate it with one or more tapes. A tape is a logical unit of storage that has a barcode, a size, and a status. You can create tapes manually or automatically using the tape auto-create feature. Tape auto-create allows you to configure your gateway to automatically create new tapes when the existing ones are full or archived. You can specify the minimum number of tapes that you want to have available at any time, the barcode prefix that you want to use for the new tapes, and the tape pool that you want to assign them to. Tape pool is a collection of tapes that have the same storage class and retention settings.

By using tape auto-create, you can ensure that you always have enough tape available on AWS for your backup jobs, and avoid the “Not Enough Space” error. This solution is the most operationally efficient one, as it does not require you to write any custom code or use any additional services. It also leverages the existing functionality and scalability of AWS Storage Gateway and Tape Gateway.

The other options are not correct for the following reasons:

A. Create an AWS Lambda function that runs on an hourly basis and checks how many tapes have available space. If the available tapes are below a certain threshold, provision more.

This option is not operationally efficient, as it requires you to write and maintain a custom Lambda function that will perform the tape creation logic. It also does not leverage the existing functionality and scalability of AWS Storage Gateway and Tape Gateway, especially the tape auto-create feature that already does what you need.

B. Install the Amazon CloudWatch agent on the on-premises system. Push the log files to a CloudWatch log group. Create an AWS Lambda function that creates more tapes when the “Not Enough Space” error appears. Create a metric filter and a metric alarm that launches the Lambda function.

This option is not operationally efficient, as it requires you to install and configure the CloudWatch agent on your on-premises system, as well as write and maintain a custom Lambda function that will perform the tape creation logic. It also does not leverage the existing functionality and scalability of AWS Storage Gateway and Tape Gateway, especially the tape auto-create feature that already does what you need.

C. Create an additional Tape Gateway with its own set of tapes. Configure Amazon Simple Notification Service (Amazon SNS) to send a notification to the backup engineer if the tapes that are associated with the primary Tape Gateway do not have available space.

This option is not correct, as it does not solve the problem of having enough tape available on AWS for your backup jobs. It only creates an additional gateway with its own set of tapes, which may or may not be sufficient for your backup needs. It also does not leverage the existing functionality and scalability of AWS Storage Gateway and Tape Gateway, especially the tape auto-create feature that already does what you need.

Explanation 9

The MOST operationally efficient way for a SysOps administrator to meet these requirements is to configure tape auto-create on the Tape Gateway. In the auto-create settings, configure a minimum number of tapes, an appropriate barcode prefix, and a tape pool.

Option A is not as efficient because it requires the creation and maintenance of an AWS Lambda function. Additionally, this option would require the Lambda function to run on an hourly basis, which could add latency and overhead.

Option B is also not as efficient as Option D because it requires the creation and maintenance of an AWS Lambda function. Additionally, this option would require the Lambda function to create more tapes when the “Not Enough Space” error appears, which could be too late to prevent the backup job from failing.

Option C is not as efficient as Option D because it requires the creation and maintenance of an additional Tape Gateway. Additionally, this option would require the backup engineer to monitor the tape capacity of both Tape Gateways, which could be time-consuming and error-prone.

Configuring tape auto-create on the Tape Gateway is the most operationally efficient way to ensure that there is always enough tape available for backup jobs. The Tape Gateway will automatically create new tapes when the number of available tapes falls below the minimum number that you configure. This will help to prevent backup jobs from failing due to a “Not Enough Space” error.

To configure tape auto-create on the Tape Gateway, follow these steps:

1. Open the AWS Storage Gateway console.
2. Select the Tape Gateway that you want to configure.
3. Click Actions.
4. Click Configure tape auto-create.
5. In the Tape auto-create settings, configure the following:
   • Minimum number of tapes: The minimum number of tapes that the Tape Gateway should have available at all times.
   • Barcode prefix: The barcode prefix for the new tapes.
   • Tape pool: The tape pool to which the new tapes should be assigned.
6. Click Save.

The Tape Gateway will start automatically creating new tapes when the number of available tapes falls below the minimum number that you configured.

Additional benefits of configuring tape auto-create:

• Tape auto-create is a fully managed feature, so you don’t need to worry about managing the infrastructure required to create and manage new tapes.
• Tape auto-create is highly scalable, so it can handle large numbers of backup jobs efficiently.
• Tape auto-create can help to reduce the risk of backup failures due to a “Not Enough Space” error.

Overall, configuring tape auto-create on the Tape Gateway is the most operationally efficient way to ensure that there is always enough tape available for backup jobs.

Explanation 10

The most operationally efficient way to meet these requirements is to configure tape auto-create on the Tape Gateway (option D).

By enabling tape auto-create on the Tape Gateway, the gateway will automatically create new tapes as needed to ensure there is sufficient capacity available for backup jobs. This is more efficient than having to manually provision new tapes (option A) or relying on error notifications/alarms to trigger tape creation (options B and C).

Some key advantages of tape auto-create include:

• It prevents backup failures due to lack of tape capacity by ensuring new tapes are created proactively before space runs out. This meets the requirement of consistently having enough tape available.
• It reduces administrative overhead by automating tape management and provisioning, rather than requiring manual intervention. This improves operational efficiency.
• Tape creation is tied directly to space availability on the Tape Gateway, making it more responsive than options that rely on error notifications or periodic checks.
• Settings like minimum tape count and barcode prefix allow controlling auto-creation policies appropriately for the environment.

Therefore, configuring tape auto-create on the Tape Gateway (option D) is the most operationally efficient approach that can meet the requirements outlined in the question. It prevents failures automatically while reducing administrative workload.

Explanation 11

To ensure that the backup jobs run smoothly and consistently without “Not Enough Space” errors, the most operationally efficient way would be to implement option D, which involves configuring tape auto-create on the Tape Gateway. This will automatically create new tapes when the available tape space falls below a certain threshold, ensuring that there is always sufficient tape capacity for the backup jobs. By setting a minimum number of tapes, an appropriate barcode prefix, and a tape pool, the SysOps administrator can maintain a consistent tape inventory and avoid running out of tapes. Additionally, this approach allows for better resource utilization and reduces the need for manual intervention, as the system will automatically create new tapes when necessary.

Explanation 12

The MOST operationally efficient way for a SysOps administrator to meet the requirements of preventing “Not Enough Space” errors and consistently having enough tape available on AWS with a Tape Gateway is option D: Configure tape auto-create on the Tape Gateway, specifying a minimum number of tapes, an appropriate barcode prefix, and a tape pool.

Here’s why option D is the most efficient choice:

1. Tape Auto-Create: AWS Storage Gateway offers a tape auto-create feature that automatically creates new virtual tapes when needed based on your configured settings. This ensures that you have an adequate number of tapes available without manual intervention.
2. Minimum Number of Tapes: With tape auto-create, you can specify a minimum number of tapes to keep available. This addresses the “Not Enough Space” error issue by ensuring that you always have a minimum number of tapes ready for backup jobs.
3. Barcode Prefix and Tape Pool: You can configure the barcode prefix and assign tapes to specific tape pools as part of the auto-create settings. This allows you to organize and manage your tapes efficiently.

Option A (creating an hourly Lambda function to check available tapes and provision more) introduces unnecessary complexity and manual intervention. Tape auto-create automates this process without the need for periodic checks.

Option B (using CloudWatch logs and Lambda with metric alarms) is more complex and may not provide real-time tape provisioning. It involves pushing log data, setting up metric filters, and creating alarms, which can be less efficient and more error-prone compared to the built-in tape auto-create feature.

Option C (creating an additional Tape Gateway and configuring SNS notifications) adds complexity and cost by introducing another Tape Gateway. It also doesn’t provide the automated tape provisioning capabilities offered by tape auto-create.

In summary, option D (tape auto-create with configured settings) is the most operationally efficient solution for ensuring sufficient tape availability and preventing “Not Enough Space” errors with AWS Storage Gateway’s Tape Gateway. It leverages built-in automation and requires minimal manual intervention.

Explanation 13

The most operationally efficient way for a SysOps administrator to meet these requirements would be:

D. Configure tape auto-create on the Tape Gateway. In the auto-create settings, configure a minimum number of tapes, an appropriate barcode prefix, and a tape pool.

AWS Storage Gateway’s Tape Gateway enables you to replace using physical tapes with virtual tapes. If you enable the tape auto-creation feature, Tape Gateway automatically creates a new tape when the current one is archived. This ensures that there is always a tape available for writing. You can specify the minimum number of available tapes, the barcode prefix, and the tape pool for the auto-created tapes.

This solution is more operationally efficient than the others because it does not require the creation of an AWS Lambda function (Option A and B), the installation of the Amazon CloudWatch agent on the on-premises system (Option B), or the creation of an additional Tape Gateway (Option C). All these options would require additional setup and resources, making them less efficient for the task at hand.

Explanation 14

The MOST operationally efficient way for a SysOps administrator to meet these requirements is option D: Configure tape auto-create on the Tape Gateway. In the auto-create settings, configure a minimum number of tapes, an appropriate barcode prefix, and a tape pool. This option provides an automated solution to ensure that there is always enough tape available on AWS without the need for manual intervention or additional resources such as Lambda functions and CloudWatch agents.

Explanation 15

The MOST operationally efficient way for a SysOps administrator to meet these requirements is to:

Configure tape auto-create on the Tape Gateway. In the auto-create settings, configure a minimum number of tapes, an appropriate barcode prefix, and a tape pool.

This will ensure that there are always enough tapes available for the backup jobs to run successfully. The other options are less efficient because they require more manual intervention or are not as scalable.

Explanation 16

The most operationally efficient way for a SysOps administrator to meet the requirements of consistently having enough tapes available on AWS and avoiding “Not Enough Space” errors is:

D. Configure tape auto-create on the Tape Gateway. In the auto-create settings, configure a minimum number of tapes, an appropriate barcode prefix, and a tape pool.

Here’s why:

Option A requires creating an AWS Lambda function that runs on an hourly basis, which can be resource-intensive and may not be the most efficient solution. Additionally, it may not be able to detect when tapes are running low in real-time.

Option B requires installing the Amazon CloudWatch agent on the on-premises system, which can be complex and may not be feasible in all environments. It also requires creating a custom Lambda function to create more tapes when the “Not Enough Space” error appears, which may not be the most efficient solution.

Option C requires creating an additional Tape Gateway, which can be costly and may not be the most efficient solution. It also requires configuring Amazon Simple Notification Service (Amazon SNS) to send a notification to the backup engineer, which may not be the most efficient way to handle the issue.

By configuring tape auto-create on the Tape Gateway, the SysOps administrator can ensure that there are always a minimum number of tapes available, without the need for custom scripts or additional hardware. The tape auto-create feature allows the Tape Gateway to automatically create new tapes when the available tapes are running low, ensuring that the backup jobs can continue to run without interruption. Additionally, the tape pool can be configured to ensure that the new tapes are distributed across multiple tape drives, providing a more reliable and efficient solution.

Therefore, option D is the most operationally efficient way to meet the requirements of consistently having enough tapes available on AWS and avoiding “Not Enough Space” errors.

Explanation 17

The most operationally efficient way to meet the requirements would be to configure tape auto-create on the Tape Gateway, as option D states. This feature allows the Tape Gateway to automatically create new tapes when the available tapes are running low, ensuring that there is always enough tape capacity available for backups.

Here’s why the other options are not as efficient:

A. Creating an AWS Lambda function to check available tape space and provision more tapes as needed would be a more reactive approach, as it would only trigger when the available tape space falls below a certain threshold. This means that backups may still fail due to insufficient tape space before the Lambda function has a chance to provision more tapes.

B. Installing the Amazon CloudWatch agent and creating a metric filter and alarm to trigger a Lambda function to create more tapes when the “Not Enough Space” error appears is a more complex solution that requires additional setup and maintenance. It also relies on the accuracy of the log files and the ability of the Lambda function to respond quickly enough to prevent backup failures.

C. Creating an additional Tape Gateway with its own set of tapes and configuring Amazon SNS to send notifications to the backup engineer when the primary Tape Gateway’s tapes are running low does not address the root cause of the issue, which is the lack of available tape space. This approach would require the backup engineer to manually create more tapes or expand the existing Tape Gateway, which could still lead to backup failures.

In contrast, option D, configuring tape auto-create on the Tape Gateway, is a proactive approach that ensures there is always enough tape capacity available for backups. By setting a minimum number of tapes, an appropriate barcode prefix, and a tape pool, the Tape Gateway can automatically create new tapes as needed, eliminating the need for manual intervention and reducing the likelihood of backup failures due to insufficient tape space.

Explanation 18

The most operationally efficient way for a SysOps administrator to meet the company’s requirements of avoiding backup failures and consistently having enough tape available on AWS would be option D: Configure tape auto-create on the Tape Gateway.

Option D suggests configuring tape auto-create on the Tape Gateway. This feature automatically creates new tapes when needed based on the configured settings. By setting a minimum number of tapes, an appropriate barcode prefix, and a tape pool, the Tape Gateway can automatically create new tapes as required, ensuring that there is always enough tape available for backups.

This approach eliminates the need for manual intervention and monitoring, as the Tape Gateway handles tape creation automatically. It ensures that backup jobs can run smoothly without encountering “Not Enough Space” errors, as new tapes are created whenever the existing ones are insufficient.

The other options, while they may offer partial solutions, are not as operationally efficient:

A. Creating an AWS Lambda function to periodically check and provision more tapes based on available space would require additional manual effort and monitoring. It would not guarantee immediate tape availability when needed, potentially leading to backup failures.

B. Installing the CloudWatch agent, pushing log files, and creating a Lambda function to respond to the “Not Enough Space” error would introduce additional complexity and dependencies. It may not provide a real-time solution, as the Lambda function might not trigger immediately upon encountering the error.

C. Creating an additional Tape Gateway with its own set of tapes and configuring Amazon SNS notifications would require managing multiple Tape Gateways and monitoring the availability of tapes across them. It adds unnecessary complexity and potential confusion for the backup engineer.

In summary, configuring tape auto-create on the Tape Gateway (option D) is the most operationally efficient solution, as it automates the creation of new tapes as needed, ensuring smooth backup operations and consistent availability of tape resources.

Explanation 19

The most operationally efficient way for a SysOps administrator to meet the requirements is to choose option D:

D. Configure tape auto-create on the Tape Gateway. In the auto-create settings, configure a minimum number of tapes, an appropriate barcode prefix, and a tape pool.

This allows the Tape Gateway itself to automatically provision new tapes in AWS when the number of tapes drops below the minimum threshold configured. This avoids having to create custom monitoring and alerting logic using Lambda/CloudWatch (options A and B). It also avoids having to manually provision an additional gateway with its own set of tapes (option C).

By leveraging the tape auto-create functionality built into the Tape Gateway, it ensures there is always enough tape capacity available without any extra operational overhead. The administrator simply needs to configure the auto-create settings properly. This meets the requirements in the most efficient manner by preventing backup job failures from lack of tape space and keeping tape capacity consistently available, all without custom code or manual intervention.

Explanation 20

The most operationally efficient way for a SysOps administrator to meet the requirements of ensuring sufficient tape availability and avoiding “Not Enough Space” errors in the AWS Storage Gateway is option D: Configure tape auto-create on the Tape Gateway.

Option D involves configuring the tape auto-create feature on the Tape Gateway. This feature allows the Tape Gateway to automatically create new tapes as needed based on the specified settings. By configuring a minimum number of tapes, an appropriate barcode prefix, and a tape pool, the Tape Gateway will ensure that a sufficient number of tapes are available to handle backup jobs.

When the Tape Gateway detects that the available space on the tapes is running low, it will automatically create new tapes according to the specified settings. This proactive approach eliminates the risk of backup jobs failing due to insufficient space.

This option is operationally efficient because it automates the process of tape creation, eliminating the need for manual intervention or periodic checks. It ensures that the company consistently has enough tapes available on AWS without the risk of running out of space.

Options A, B, and C also provide potential solutions, but they are not as operationally efficient as option D.

Option A suggests creating an AWS Lambda function that runs on an hourly basis to check the available tape space and provision more tapes if the threshold is below a certain level. While this approach can ensure sufficient tape availability, it requires periodic checks and manual intervention. It may also lead to delays in provisioning tapes if the checks are not frequent enough.

Option B involves installing the Amazon CloudWatch agent on the on-premises system, pushing log files to a CloudWatch log group, and creating a Lambda function triggered by a metric alarm. The Lambda function then creates more tapes when the “Not Enough Space” error occurs. Although this option addresses the issue, it requires additional setup and complexity with log monitoring, metric filters, and alarms.

Option C suggests creating an additional Tape Gateway with its own set of tapes and configuring Amazon Simple Notification Service (Amazon SNS) to send notifications to the backup engineer if the primary Tape Gateway’s tapes do not have available space. While this option provides a notification mechanism, it does not directly address the issue of ensuring sufficient tape availability and may result in delays if the backup engineer is not immediately available to take action.

In summary, option D is the most operationally efficient approach as it automates tape creation based on predefined settings, ensuring consistent tape availability and avoiding “Not Enough Space” errors without the need for manual intervention or additional setup.

Explanation 21

The MOST operationally efficient way for a SysOps administrator to meet the requirements of consistently having enough tape available on AWS and avoiding “Not Enough Space” errors is option C: Create an additional Tape Gateway with its own set of tapes.

Here’s why:

1. Redundancy: Having a second Tape Gateway provides additional redundancy, which means that if one Tape Gateway fails, the other can continue to handle backup jobs without interruption.
2. Capacity planning: By having two Tape Gateways, the administrator can more easily forecast and plan for future capacity needs. If one Tape Gateway is running low on space, the administrator can simply create more tapes on the second Tape Gateway without affecting backup jobs.
3. Fault tolerance: With two Tape Gateways, the administrator can more easily ensure that there is always enough tape capacity available to handle backup jobs. Even if one Tape Gateway fails, the other can continue to handle the workload.
4. Scalability: Adding a second Tape Gateway is a more scalable solution than other options. For example, if the company’s backup workload grows, the administrator can simply add more tapes to the second Tape Gateway without having to modify the existing infrastructure.
5. Automation: Option C allows for automated tape management through the use of Amazon Simple Notification Service (Amazon SNS). The administrator can configure Amazon SNS to send notifications to the backup engineer when the tapes that are associated with the primary Tape Gateway do not have available space, ensuring that the backup engineer can take proactive action to address the issue.

In contrast, options A and B are less operationally efficient for several reasons:

• Option A requires the use of AWS Lambda functions, which can be resource-intensive and may not be optimal for high-volume backup workloads.
• Option B requires the use of Amazon CloudWatch, which may not provide the same level of visibility into tape availability as a dedicated Tape Gateway.

In summary, creating a second Tape Gateway is the most operationally efficient way for a SysOps administrator to meet the requirements of consistently having enough tape available on AWS and avoiding “Not Enough Space” errors.

Explanation 22

Option B is the most operationally efficient way for a SysOps administrator to meet the requirements in this scenario.

By installing the Amazon CloudWatch agent on the on-premises system and pushing the log files to a CloudWatch log group, you can monitor the system’s storage usage. You can then create an AWS Lambda function that triggers when the “Not Enough Space” error appears in the logs. This Lambda function can automatically create more tapes in AWS Storage Gateway to ensure sufficient space for backups.

To implement this solution, you would need to follow these steps:

1. Install the Amazon CloudWatch agent on the on-premises system: This agent collects and sends log files to CloudWatch for monitoring.
2. Configure the CloudWatch agent to push the log files to a CloudWatch log group: This allows you to centralize and analyze the logs.
3. Create an AWS Lambda function: This function should be triggered by a CloudWatch metric alarm that monitors the log group for the “Not Enough Space” error. The Lambda function should have the necessary permissions to interact with AWS Storage Gateway.
4. Configure the Lambda function to create more tapes: When the “Not Enough Space” error is detected, the Lambda function should automatically create additional tapes in AWS Storage Gateway. This ensures that there is enough space for backups.

By automating the process of tape creation based on the storage usage, you can prevent backup failures due to insufficient space. This solution is operationally efficient as it eliminates the need for manual intervention and ensures a consistent availability of tapes on AWS.

Explanation 23

I would answer the question as follows:

The correct option is A. Creating an AWS Lambda function that runs on an hourly basis and checks how many tapes have available space is the most operationally efficient way for a SysOps administrator to meet the requirements. This option ensures that there is always enough tape available on AWS without relying on manual intervention or error detection. The Lambda function can use the ListTapes API to get the status of the tapes and the CreateTapes API to provision more tapes as needed. This option also allows the administrator to set a threshold for the number of available tapes that suits their backup needs and budget.

Option B is incorrect because it relies on error detection rather than proactive monitoring. Pushing the log files to a CloudWatch log group and creating a metric filter and a metric alarm that launches a Lambda function are unnecessary steps that add complexity and latency to the solution. Moreover, this option does not guarantee that there will be enough tape available on AWS at all times, as it only creates more tapes when an error occurs.

Option C is incorrect because it creates redundancy and waste. Creating an additional Tape Gateway with its own set of tapes is not operationally efficient, as it doubles the cost and maintenance of the solution. Moreover, this option does not solve the problem of having enough tape available on AWS, as it only provides a backup option if the primary Tape Gateway runs out of space. Configuring Amazon SNS to send a notification to the backup engineer is also not efficient, as it requires manual intervention to create more tapes.

Option D is incorrect because it does not allow the administrator to control the number and size of the tapes. Configuring tape auto-create on the Tape Gateway is a simple way to ensure that there is always tape available on AWS, but it does not allow the administrator to specify a minimum number of tapes, a barcode prefix, or a tape pool. This option may create more tapes than needed or use a different naming convention or pool than desired.
