Explanation 1

The MOST operationally efficient way to remediate the issue is to enable S3 Transfer Acceleration for the new S3 bucket and verify that the developers are using the DOC-EXAMPLE-BUCKET.s3-accelerate.amazonaws.com endpoint name in their API calls.

Option A is not the most operationally efficient solution because it would require the SysOps administrator to provision and manage an Amazon ElastiCache for Redis cluster. This can be time-consuming and error-prone. Additionally, this solution would not provide any performance benefits for uploading large sets of files to S3.

Option B is not the most operationally efficient solution because it would add additional latency to the upload process. CloudFront is designed to deliver web content to users with low latency, but it is not optimized for uploading large sets of files to S3.

Option D is not the most operationally efficient solution because it would require the developers to change their API calls. This can be time-consuming and error-prone. Additionally, this solution would not provide any performance benefits for uploading large sets of files to S3.

To enable S3 Transfer Acceleration for the new S3 bucket:

1. Open the Amazon S3 console.
2. Click the new S3 bucket.
3. Click Properties.
4. In the Transfer Acceleration section, select Enable Transfer Acceleration.
5. Click Save.

To verify that the developers are using the DOC-EXAMPLE-BUCKET.s3-accelerate.amazonaws.com endpoint name in their API calls:

• Contact the developers and ask them to verify their API calls.

Once the developers are using the DOC-EXAMPLE-BUCKET.s3-accelerate.amazonaws.com endpoint name in their API calls, the upload performance from all geographic areas should be improved.

Additional benefits of using S3 Transfer Acceleration:

• S3 Transfer Acceleration is a fully managed service, so the SysOps administrator does not need to worry about managing the infrastructure required to run the service.
• S3 Transfer Acceleration is easy to use, and it can be enabled for any S3 bucket with a few clicks.
• S3 Transfer Acceleration is cost-effective, and it is only charged when data is transferred through the service.

Overall, enabling S3 Transfer Acceleration is the most operationally efficient way to remediate the issue of slow upload performance from certain geographic areas.

Explanation 2

To remediate the issue of lower upload performance from certain geographic areas for the new Amazon S3 bucket, the most appropriate option for the SysOps administrator is option C: Enable S3 Transfer Acceleration for the new S3 bucket and ensure that the developers are using the DOC-EXAMPLE-BUCKET.s3-accelerate.amazonaws.com endpoint name in their API calls.

Here’s a detailed explanation of why option C is the correct choice:

• S3 Transfer Acceleration: S3 Transfer Acceleration is a feature of Amazon S3 that utilizes Amazon CloudFront’s globally distributed edge locations to accelerate uploads to S3 buckets. By enabling S3 Transfer Acceleration, the SysOps administrator can improve upload performance for users across the world, especially in regions that experience slower upload speeds.
• Enable for New S3 Bucket: The SysOps administrator should enable S3 Transfer Acceleration specifically for the new S3 bucket, DOC-EXAMPLE-BUCKET, that is experiencing lower upload performance. Enabling it for this bucket ensures that the upload performance for files uploaded to this particular bucket is optimized.
• Endpoint Name: The administrator should verify that the developers are using the DOC-EXAMPLE-BUCKET.s3-accelerate.amazonaws.com endpoint name in their API calls. This endpoint is specifically designed for S3 Transfer Acceleration and ensures that the upload requests are routed through the closest CloudFront edge location to the user, improving the upload performance.

Option A suggests provisioning an Amazon ElastiCache for Redis cluster for the new S3 bucket. While ElastiCache can improve performance for certain workloads, it is primarily used for caching frequently accessed data and may not directly address the issue of lower upload performance from certain geographic areas.

Option B suggests adding the new S3 bucket to a new Amazon CloudFront distribution. While CloudFront can improve performance by caching content closer to users, it may not directly address the issue of lower upload performance and may introduce additional configuration complexity.

Option D suggests using S3 multipart upload for the new S3 bucket and ensuring that developers use region-specific S3 endpoint names in their API calls. While multipart upload can help with large file uploads, it does not specifically address the issue of lower upload performance from certain geographic areas.

In summary, option C – enabling S3 Transfer Acceleration for the new S3 bucket and ensuring that developers use the DOC-EXAMPLE-BUCKET.s3-accelerate.amazonaws.com endpoint name in their API calls – is the most appropriate choice for remediating the issue of lower upload performance from certain geographic areas. This approach leverages the global edge locations of CloudFront to optimize upload performance and improve the user experience.

Explanation 3

The correct answer is C. S3 Transfer Acceleration is a feature that enables fast, easy, and secure transfers of files over long distances between users and an S3 bucket. It works by routing requests to S3 through edge locations of the AWS global network, which are closer to the users. This reduces the latency and improves the throughput of the uploads. The other options are not valid solutions for this issue. Option A is irrelevant because ElastiCache for Redis is a service that provides in-memory data store and caching, not file storage or transfer. Option B is incorrect because CloudFront is a content delivery network that speeds up the delivery of static and dynamic web content, not file uploads. Option D is also incorrect because S3 multipart upload is a feature that allows breaking a large object into smaller parts and uploading them independently, not a feature that improves the upload performance from different geographic regions.

Explanation 4

The correct answer is option C. Enable S3 Transfer Acceleration for the new S3 bucket. Verify that the developers are using the DOC-EXAMPLE-BUCKET.s3-accelerate.amazonaws.com endpoint name in their API calls.

The reason is that S3 Transfer Acceleration is a feature that enables fast, easy, and secure transfers of files over long distances between your client and an S3 bucket. S3 Transfer Acceleration leverages the AWS edge network, which is a global network of 216 points of presence. By using S3 Transfer Acceleration, you can improve the upload performance from certain geographic areas by up to 50% or more.

To use S3 Transfer Acceleration, you need to enable it for your S3 bucket. You can do this by using the AWS Management Console, the AWS CLI, or the AWS SDKs. After enabling S3 Transfer Acceleration, you need to verify that the developers are using the S3 Transfer Acceleration endpoint name in their API calls. The endpoint name has the following format: bucketname.s3-accelerate.amazonaws.com. For example, if your bucket name is DOC-EXAMPLE-BUCKET, then your endpoint name is DOC-EXAMPLE-BUCKET.s3-accelerate.amazonaws.com.

Option A is incorrect because provisioning an Amazon ElastiCache for Redis cluster for the new S3 bucket will not improve the upload performance from certain geographic areas. Amazon ElastiCache for Redis is a fully managed, in-memory data store and cache service that provides sub-millisecond latency and high throughput for applications. However, ElastiCache for Redis does not have any direct integration with S3 or any effect on S3 transfers. To use ElastiCache for Redis, you need to provision a cluster in a specific Region and connect to it from your application. This does not help with transferring files over long distances to an S3 bucket.

Option B is incorrect because adding the new S3 bucket to a new Amazon CloudFront distribution will not improve the upload performance from certain geographic areas. Amazon CloudFront is a fast content delivery network (CDN) service that securely delivers data, videos, applications, and APIs to customers globally with low latency and high transfer speeds. However, CloudFront is mainly designed for delivering content from your origin (such as an S3 bucket) to your viewers (such as web browsers or mobile devices). CloudFront does not optimize the transfers from your viewers to your origin. To use CloudFront, you need to create a distribution and configure it with your origin and other settings. This does not help with uploading files over long distances to an S3 bucket.

Option D is incorrect because using S3 multipart upload for the new S3 bucket will not improve the upload performance from certain geographic areas. S3 multipart upload is a feature that allows you to upload a single object as a set of parts. Each part is a contiguous portion of the object’s data. You can use multipart upload for objects larger than 100 MB or when you want to improve the upload experience for unreliable networks. However, multipart upload does not optimize the transfers over long distances or across different Regions. To use multipart upload, you need to initiate a multipart upload, upload each part separately, and complete the multipart upload. This does not help with uploading files over long distances to an S3 bucket.

Explanation 5

To remediate the issue of lower upload performance from certain geographic areas for the new S3 bucket, the SysOps administrator should choose option C. This option involves enabling S3 Transfer Acceleration for the new S3 bucket and verifying that the developers are using the DOC-EXAMPLE-BUCKET.s3-accelerate.amazonaws.com endpoint name in their API calls.

Here’s a breakdown of each option:

Option A: Provision an Amazon ElastiCache for Redis cluster for the new S3 bucket. Provide the developers with the configuration endpoint of the cluster for use in their API calls.

• This option involves provisioning an Amazon ElastiCache for Redis cluster for the new S3 bucket.
• While ElastiCache can improve performance for certain workloads, it is not specifically designed to address upload performance issues with S3 buckets.

Option B: Add the new S3 bucket to a new Amazon CloudFront distribution. Provide the developers with the domain name of the new distribution for use in their API calls.

• This option involves adding the new S3 bucket to a new Amazon CloudFront distribution.
• While CloudFront can improve performance by caching content closer to end users, it may not directly address upload performance issues.

Option C: Enable S3 Transfer Acceleration for the new S3 bucket. Verify that the developers are using the DOC-EXAMPLE-BUCKET.s3-accelerate.amazonaws.com endpoint name in their API calls.

• This option involves enabling S3 Transfer Acceleration for the new S3 bucket.
• By enabling Transfer Acceleration, data can be uploaded to an AWS edge location closer to end users, improving upload performance from certain geographic areas.

Option D: Use S3 multipart upload for the new S3 bucket. Verify that the developers are using Region-specific S3 endpoint names such as DOC-EXAMPLE-BUCKETS3.[Region].amazonaws.com in their API calls.

• This option involves using S3 multipart upload for the new S3 bucket.
• While multipart upload can improve performance for large files, it may not directly address upload performance issues from certain geographic areas.

In summary, option C is recommended as it leverages S3 Transfer Acceleration to improve upload performance from certain geographic areas. By enabling Transfer Acceleration and ensuring that developers use the appropriate endpoint name in their API calls, data can be uploaded more efficiently.

Explanation 6

To remediate the issue of lower upload performance from certain geographic areas for the new S3 bucket, the SysOps administrator should enable S3 Transfer Acceleration for the new S3 bucket and verify that the developers are using the DOC-EXAMPLE-BUCKET.s3-accelerate.amazonaws.com endpoint name in their API calls. S3 Transfer Acceleration is a feature that enables faster uploads to Amazon S3 by leveraging Amazon CloudFront’s globally distributed edge locations. By using this feature, the upload performance from certain geographic areas can be significantly improved.

Option A, provisioning an Amazon ElastiCache for Redis cluster for the new S3 bucket, is not a suitable solution for improving upload performance.

Option B, adding the new S3 bucket to a new Amazon CloudFront distribution and providing the developers with the domain name of the new distribution for use in their API calls, can improve performance by caching content closer to users. However, it may not directly address the issue of lower upload performance from certain geographic areas.

Option D, using S3 multipart upload for the new S3 bucket and verifying that the developers are using Region-specific S3 endpoint names such as DOC-EXAMPLE-BUCKETS3, [Region] amazonaws.com in their API calls, is not specifically designed to address lower upload performance from certain geographic areas.

Therefore, option C, enabling S3 Transfer Acceleration for the new S3 bucket and verifying that the developers are using the DOC-EXAMPLE-BUCKET.s3-accelerate.amazonaws.com endpoint name in their API calls, is the most appropriate solution to remediate this issue.

Explanation 7

The BEST option to remediate the issue of lower upload performance from certain geographic areas for the new S3 bucket is to enable S3 Transfer Acceleration for the new S3 bucket.

Option A is not the best option because ElastiCache for Redis is a key-value store, and it is not designed for storing large files.

Option B is not the best option because CloudFront is a content delivery network (CDN) that is designed for delivering static and dynamic web content, not for storing large files.

Option D is not the best option because S3 multipart upload is a feature that allows you to upload large objects to S3 in parts. This can improve upload performance, but it is not the best solution for this specific issue.

S3 Transfer Acceleration is a service that accelerates data transfers to and from S3 buckets. It uses Amazon CloudFront’s globally distributed edge locations to optimize network paths and improve transfer speeds.

To enable S3 Transfer Acceleration for the new S3 bucket:

1. Open the Amazon S3 console.
2. Click the name of the new S3 bucket.
3. Click the Properties tab.
4. Under Transfer Acceleration, click Enable.
5. Click Save.

Once S3 Transfer Acceleration is enabled, the developers will need to update their API calls to use the DOC-EXAMPLE-BUCKET.s3-accelerate.amazonaws.com endpoint name.

This is the best option to remediate the issue because it is the most efficient and cost-effective solution. It is also the easiest solution to implement and manage.

Additional benefits of using S3 Transfer Acceleration:

• S3 Transfer Acceleration can improve upload performance by up to 50%.
• S3 Transfer Acceleration is easy to use and manage. There is no additional charge for using S3 Transfer Acceleration.
• S3 Transfer Acceleration is available in all AWS Regions.

Overall, enabling S3 Transfer Acceleration for the new S3 bucket is the best way to remediate the issue of lower upload performance from certain geographic areas.

Explanation 8

The correct answer is C. Enable S3 Transfer Acceleration for the new S3 bucket. Verify that the developers are using the DOC-EXAMPLE-BUCKET.s3-accelerate.amazonaws.com endpoint name in their API calls.

Explanation:

Amazon S3 is a service that provides scalable, durable, and secure object storage. You can use S3 to store and retrieve any amount of data from anywhere on the web. You can also use S3 to host static websites, serve media files, or store backups.

S3 Transfer Acceleration is a feature that enables you to speed up the upload of large sets of files to S3 buckets from users across the world. S3 Transfer Acceleration leverages the AWS global network and edge locations to route your upload requests to the nearest S3 endpoint, which can reduce the latency and improve the throughput of your uploads.

To use S3 Transfer Acceleration, you need to enable it for your S3 bucket from the S3 console, AWS CLI, or AWS SDKs. You also need to use a different endpoint name for your API calls, which has the format bucketname.s3-accelerate.amazonaws.com. For example, if your bucket name is DOC-EXAMPLE-BUCKET, you need to use DOC-EXAMPLE-BUCKET.s3-accelerate.amazonaws.com as the endpoint name for your uploads.

By using this solution, you can remediate the issue of low upload performance from certain geographic areas for your new S3 bucket. This solution meets the requirements of the company, as it allows them to provision their EC2 instances by using only approved EC2 instance configurations. This solution is also the most operationally efficient one, as it does not require them to use any additional services or tools. It also leverages the existing functionality and scalability of S3 and S3 Transfer Acceleration.

The other options are not correct for the following reasons:

A. Provision an Amazon ElastiCache for Redis cluster for the new S3 bucket. Provide the developers with the configuration endpoint of the cluster for use in their API calls.

This option is not correct, as ElastiCache for Redis is a service that provides in-memory data store and caching for your applications. It does not provide any functionality or benefit for uploading files to S3 buckets.

B. Add the new S3 bucket to a new Amazon CloudFront distribution. Provide the developers with the domain name of the new distribution for use in their API calls.

This option is not correct, as CloudFront is a service that provides content delivery network (CDN) for your web applications. It can help you improve the performance and availability of your web content by caching it at edge locations near your users. However, CloudFront does not provide any functionality or benefit for uploading files to S3 buckets.

D. Use S3 multipart upload for the new S3 bucket. Verify that the developers are using Region-specific S3 endpoint names such as DOC-EXAMPLE-BUCKETS3, [Region] amazonaws.com in their API calls.

This option is not correct, as S3 multipart upload is a feature that enables you to upload large files to S3 buckets in multiple parts concurrently. It can help you improve the performance and reliability of your uploads by allowing you to resume or retry failed parts without affecting the rest of the upload. However, S3 multipart upload does not provide any functionality or benefit for uploading files from different geographic areas to S3 buckets.

Explanation 9

• Developers should use the Transfer Acceleration endpoint URL (DOC-EXAMPLE-BUCKET.s3-accelerate.amazonaws.com) in API calls to leverage the accelerated uploads.
• Option A (ElastiCache for Redis) does not address the upload performance issue.
• Option B (CloudFront distribution) may help download speeds but not uploads.
• Option D (Multipart upload with region-specific endpoints) does not provide a solution for the specific problem of improving upload performance from certain geographic locations.

In summary, S3 Transfer Acceleration (Option C) is the best choice as it was designed to optimize cross-region upload performance, which is the core issue being experienced. The other options do not directly remedy the problem.

Explanation 12

The most appropriate option for remediating the lower upload performance issue for the new S3 bucket is:

Option C: Enable S3 Transfer Acceleration for the new S3 bucket. Verify that the developers are using the DOC-EXAMPLE-BUCKET.s3-accelerate.amazonaws.com endpoint name in their API calls.

Here’s a detailed explanation of why Option C is the recommended choice:

• S3 Transfer Acceleration: S3 Transfer Acceleration is a feature that improves the speed of uploading large objects to Amazon S3 by using Amazon CloudFront’s globally distributed edge locations. It accelerates uploads by routing data through Amazon CloudFront, which can significantly improve upload speeds, especially for users in geographically distant areas.
• Global Upload Performance: Since the issue is with lower upload performance from certain geographic areas, enabling S3 Transfer Acceleration is an effective solution. It leverages Amazon CloudFront’s edge locations to provide faster upload speeds to users across the world.
• Endpoint Configuration: When you enable S3 Transfer Acceleration for the S3 bucket, you get a new endpoint in the format DOC-EXAMPLE-BUCKET.s3-accelerate.amazonaws.com. You need to ensure that the developers are using this endpoint in their API calls to take advantage of the accelerated upload performance.

Why Option C is preferable over the other options:

• Option A (ElastiCache for Redis): Amazon ElastiCache for Redis is used for caching data and won’t directly improve upload performance for S3. It’s not the appropriate solution for addressing slow uploads to an S3 bucket.
• Option B (Amazon CloudFront): While adding the S3 bucket to a CloudFront distribution can improve download performance by caching objects globally, it won’t directly address the issue of slow uploads to the S3 bucket.
• Option D (S3 Multipart Upload): Using S3 multipart upload is a good practice for large file uploads, but it doesn’t inherently address the geographic upload performance issue. It focuses more on the upload process itself rather than global upload performance.

Option C, enabling S3 Transfer Acceleration, is the most suitable choice for addressing slow upload performance from certain geographic areas. It utilizes Amazon CloudFront’s global edge locations to accelerate uploads to the new S3 bucket, making it an effective solution for the given scenario.

Explanation 13

The best solution to improve upload performance from certain geographic areas would be option C: Enable S3 Transfer Acceleration for the new S3 bucket. Verify that the developers are using the DOC-EXAMPLE-BUCKET.s3-accelerate.amazonaws.com endpoint name in their API calls.

Amazon S3 Transfer Acceleration enables fast, easy, and secure transfers of files over long distances between your client and an S3 bucket. It takes advantage of Amazon CloudFront’s globally distributed edge locations. As the data arrives at an edge location, data is routed to Amazon S3 over an optimized network path.

The other options are less suitable. Option A, provisioning an Amazon ElastiCache for Redis cluster, would not directly improve S3 upload performance. Option B, adding the new S3 bucket to a new Amazon CloudFront distribution, would improve download performance but not necessarily upload performance. Option D, using S3 multipart upload, can improve upload performance for individual large files, but it does not optimize the network path as S3 Transfer Acceleration does.

Explanation 14

The MOST operationally efficient way to remediate the issue of low upload performance from certain geographic areas for the new S3 bucket is to enable S3 Transfer Acceleration for the new S3 bucket.

Option A is not the most operationally efficient way to remediate the issue because it would require the SysOps administrator to provision and manage an Amazon ElastiCache for Redis cluster. ElastiCache for Redis is a caching service that can improve the performance of applications that need to access data quickly. However, it is not necessary to use ElastiCache for Redis to improve the upload performance of an S3 bucket.

Option B is not the most operationally efficient way to remediate the issue because it would require the SysOps administrator to create and manage a new CloudFront distribution. CloudFront is a content delivery network (CDN) that can improve the performance of websites and applications by delivering content from servers that are located close to the user. However, it is not necessary to use CloudFront to improve the upload performance of an S3 bucket.

Option D is not the most operationally efficient way to remediate the issue because it would require the developers to make changes to their API calls. Additionally, using Region-specific S3 endpoint names does not guarantee that the upload performance will be improved.

S3 Transfer Acceleration is a feature that can improve the upload and download performance of S3 buckets. S3 Transfer Acceleration uses a global network of edge locations to improve the performance of transfers over long distances.

To enable S3 Transfer Acceleration for the new S3 bucket:

1. Open the Amazon S3 console.
2. Click Buckets.
3. Select the new S3 bucket.
4. Click Properties.
5. In the Transfer Acceleration section, select Enabled.
6. Click Save.

The SysOps administrator can now verify that the developers are using the DOC-EXAMPLE-BUCKET.s3-accelerate.amazonaws.com endpoint name in their API calls. This will ensure that the uploads are being routed through the S3 Transfer Acceleration network, which will improve the upload performance for users in all geographic areas.

This is the most operationally efficient way to remediate the issue of low upload performance from certain geographic areas for the new S3 bucket because it is the fastest and least error-prone method. It also does not require the developers to make any changes to their API calls.

Explanation 15

The correct answer is C. Enable S3 Transfer Acceleration for the new S3 bucket. Verify that the developers are using the DOC-EXAMPLE-BUCKET.s3-accelerate.amazonaws.com endpoint name in their API calls.

Amazon S3 Transfer Acceleration can improve the upload performance of the new S3 bucket for users from geographic areas that are far from the S3 bucket’s AWS Region. This feature uses the Amazon CloudFront edge network to minimize the latency encountered while uploading large files, thus improving the upload performance. By verifying that the developers are using the accelerated endpoint in their API calls, the SysOps administrator can ensure that the files are being uploaded through the optimized path, resulting in faster uploads.

Explanation 16

The correct answer is C: Enable S3 Transfer Acceleration for the new S3 bucket. Verify that the developers are using the DOC-EXAMPLE-BUCKET.s3-accelerate.amazonaws.com endpoint name in their API calls.

Amazon S3 Transfer Acceleration is a service that improves the performance of data transfers to and from Amazon S3. By enabling S3 Transfer Acceleration, the SysOps administrator can improve the upload performance from certain geographic areas for the new S3 bucket.

To use S3 Transfer Acceleration, the developers need to use the DOC-EXAMPLE-BUCKET.s3-accelerate.amazonaws.com endpoint name in their API calls. This endpoint name will automatically route the data transfer through the optimal AWS edge location, which will improve the upload performance.

Explanation 17

I would recommend option C: Enable S3 Transfer Acceleration for the new S3 bucket. This option would help improve the upload performance from certain geographic areas.

Here’s why:

S3 Transfer Acceleration is a feature of Amazon S3 that uses AWS infrastructure to accelerate the transfer of large data sets over long distances. When enabled, S3 Transfer Acceleration can significantly improve the upload performance of large files from geographic locations that are far from the S3 bucket’s location.

In this scenario, since the new S3 bucket, DOC-EXAMPLE-BUCKET, is receiving regular uploads of large sets of files from users worldwide, enabling S3 Transfer Acceleration for this bucket can help improve the upload performance from certain geographic areas.

To enable S3 Transfer Acceleration for the new S3 bucket, the SysOps administrator can follow these steps:

1. Navigate to the Amazon S3 console and select the new S3 bucket, DOC-EXAMPLE-BUCKET.
2. Click on the “Properties” tab and scroll down to the “Access Control” section.
3. Click on “Edit” next to “Permissions” and add the appropriate IAM role or user to the bucket’s access control list. This role or user should have “Read” and “Write” permissions to the bucket.
4. Click “Save” to save the changes.
5. Click on the “Settings” tab and scroll down to the “Transfer Acceleration” section.
6. Click on “Edit” and select “Enable Transfer Acceleration” to turn on the feature.
7. Click “Save” to save the changes.

Once S3 Transfer Acceleration is enabled for the new S3 bucket, the developers can use the DOC-EXAMPLE-BUCKET.s3-accelerate.amazonaws.com endpoint name in their API calls to upload files to the bucket. This endpoint name is specific to the S3 Transfer Acceleration feature and will route the uploads through the closest AWS edge location, potentially improving upload performance.

Note that options A, B, and D are not the best solutions for this scenario. Provisioning an Amazon ElastiCache for Redis cluster (Option A) would not directly address the upload performance issue. Adding the new S3 bucket to a new Amazon CloudFront distribution (Option B) would also not address the performance issue and would only provide a cache layer for the S3 bucket. Using S3 multipart upload (Option D) would not be necessary for this scenario, as the issue is related to upload performance rather than uploading large files in a single request.

Explanation 18

Option C is the correct answer: Enable S3 Transfer Acceleration for the new S3 bucket. Verify that the developers are using the DOC-EXAMPLE-BUCKET.s3-accelerate.amazonaws.com endpoint name in their API calls.

Explanation:
The issue described in the question is related to lower upload performance from certain geographic areas for the new S3 bucket. To remediate this issue, enabling S3 Transfer Acceleration is the recommended solution. S3 Transfer Acceleration utilizes the Amazon CloudFront network to accelerate uploads to S3 buckets by optimizing data transfer over long distances.

By enabling S3 Transfer Acceleration for the new S3 bucket, the upload performance can be improved from various geographic locations. To ensure that the developers are using the optimized endpoint for their API calls, they should be instructed to use the DOC-EXAMPLE-BUCKET.s3-accelerate.amazonaws.com endpoint name instead of the standard S3 endpoint.

Option A, provisioning an Amazon ElastiCache for Redis cluster, is not the appropriate solution in this scenario. ElastiCache is a caching service and is not directly related to improving upload performance for S3 buckets.

Option B, adding the new S3 bucket to a new Amazon CloudFront distribution, may improve performance for retrieving files from the bucket, but it won’t directly address the issue of slower upload performance.

Option D, using S3 multipart upload and Region-specific S3 endpoint names, does not specifically address the issue of slower upload performance from certain geographic areas. Multipart upload is a mechanism for uploading large files in parts and does not directly optimize performance for specific regions.

Therefore, the best option to remediate the issue of lower upload performance is to enable S3 Transfer Acceleration and ensure that the developers use the correct endpoint in their API calls.

Explanation 19

The correct answer is (C) Enable S3 Transfer Acceleration for the new S3 bucket.

When the new S3 bucket is put into production, the upload performance from certain geographic areas may be lower than expected due to the distance between the uploaders and the S3 bucket. This is because S3 buckets are located in different availability zones and regions around the world, and the distance between the uploader and the S3 bucket can significantly affect the upload performance.

S3 Transfer Acceleration is a feature that can help improve the upload performance of S3 buckets by accelerating the transfer of data between the uploader and the S3 bucket. By enabling S3 Transfer Acceleration for the new S3 bucket, the SysOps administrator can improve the upload performance of the bucket, regardless of the geographic location of the uploaders.

To enable S3 Transfer Acceleration, the SysOps administrator can use the AWS Management Console, the AWS CLI, or an SDK to configure the S3 bucket to use the S3 Transfer Acceleration feature. Once enabled, the developers can use the DOC-EXAMPLE-BUCKET.s3-accelerate.amazonaws.com endpoint name in their API calls to access the accelerated upload endpoint.

Option (A) provisioning an Amazon ElastiCache for Redis cluster for the new S3 bucket is not the appropriate solution as it is not related to improving the upload performance of the S3 bucket.

Option (B) adding the new S3 bucket to a new Amazon CloudFront distribution is also not the appropriate solution as it is not related to improving the upload performance of the S3 bucket. CloudFront is used for content delivery, not for improving upload performance.

Option (D) using S3 multipart upload is related to improving upload performance, but it is not the appropriate solution in this case as it requires the developers to use Region-specific S3 endpoint names, which may not be feasible or desirable in all cases.

Therefore, the correct answer is (C) Enable S3 Transfer Acceleration for the new S3 bucket.

Explanation 20

The answer is C.

Enabling S3 Transfer Acceleration for the new S3 bucket is the best solution here to remediate the lower than expected upload performance from certain geographic areas.

S3 Transfer Acceleration takes advantage of Amazon’s globally distributed Edge Location network to provide improved upload performance to S3 buckets for users worldwide. When Transfer Acceleration is enabled, users upload objects directly to the Edge Location nearest to them, which then transfers the data to S3 over the AWS global network. This utilizes multiple network paths which are likely to perform better than a single network connection from the user directly to the S3 Region hosting the bucket.

By enabling Transfer Acceleration for the new S3 bucket, uploads will be accelerated as they are routed through the nearest Edge Location, improving performance for users uploading from locations experiencing suboptimal connectivity directly to the S3 Region.

The developers would then need to use the S3 Transfer Accelerated endpoint which ends in s3-accelerate.amazonaws.com, as indicated in option C, to take advantage of the acceleration.

The other options would not directly address the issue of lower than expected upload performance from certain geographic areas. Provisioning an ElastiCache cluster or adding the bucket to CloudFront are not related to improving cross-region upload speeds. And using multipart upload vs single part uploads would not affect the underlying network paths being used.

Therefore, the correct answer is C – enabling S3 Transfer Acceleration for the new bucket and using the accelerated endpoint. This is the best way to remediate the performance issue described for certain user locations uploading files.

Explanation 21

The correct answer is C. Enable S3 Transfer Acceleration for the new S3 bucket. Verify that the developers are using the DOC-EXAMPLE-BUCKET.s3-accelerate.amazonaws.com endpoint name in their API calls.

When a new S3 bucket is created and put into production, it may not have the same performance as the existing S3 buckets, especially if it’s in a different region or has different configuration settings. One way to improve the upload performance of the new S3 bucket is to enable S3 Transfer Acceleration, which uses Amazon’s network infrastructure to accelerate data transfer between the client and S3.

To enable S3 Transfer Acceleration for the new S3 bucket, the SysOps administrator should follow these steps:

1. Navigate to the S3 console and select the new S3 bucket.
2. Click on the “Properties” tab and scroll down to the “Transfer Acceleration” section.
3. Click on the “Edit” button next to “Transfer Acceleration” and enable the feature.
4. Provide the developers with the endpoint name for the accelerated S3 bucket, which should be in the format DOC-EXAMPLE-BUCKET.s3-accelerate.amazonaws.com.

Once the SysOps administrator enables S3 Transfer Acceleration for the new S3 bucket and provides the developers with the endpoint name, the upload performance from clients worldwide should improve. Therefore, option C is the correct answer.

Option A is incorrect because provisioning an ElastiCache for Redis cluster may improve performance for applications that use S3 as a cache store, but it won’t directly improve S3 upload performance.

Option B is incorrect because creating a CloudFront distribution for the new S3 bucket may improve performance for users who download objects from the bucket, but it won’t directly improve upload performance.

Option D is incorrect because using S3 multipart uploads may improve performance for large file uploads, but it’s not directly related to the issue of low upload performance from certain geographic areas.

Explanation 22

To remediate the issue of lower upload performance from certain geographic areas for the new S3 bucket, the SysOps administrator should consider option C: Enable S3 Transfer Acceleration for the new S3 bucket and verify that the developers are using the DOC-EXAMPLE-BUCKET.s3-accelerate.amazonaws.com endpoint name in their API calls.

S3 Transfer Acceleration is a feature provided by Amazon S3 that utilizes the Amazon CloudFront content delivery network (CDN) to accelerate uploads to S3 buckets. It works by leveraging CloudFront’s globally distributed edge locations to route the data through the nearest edge location, reducing the latency and improving the upload speed.

By enabling S3 Transfer Acceleration for the new S3 bucket, the upload performance from different geographic areas can be significantly improved. The developers need to ensure that they are using the specific endpoint name, DOC-EXAMPLE-BUCKET.s3-accelerate.amazonaws.com, in their API calls to take advantage of this acceleration.

Options A, B, and D are not the optimal solutions in this scenario:

Option A, provisioning an Amazon ElastiCache for Redis cluster, is typically used for caching frequently accessed data to improve read performance. It is not directly related to improving upload performance for S3 buckets.

Option B, adding the new S3 bucket to a new Amazon CloudFront distribution, would improve download performance from the bucket but may not directly address the upload performance issue.

Option D, using S3 multipart upload and Region-specific endpoint names, does not address the specific issue of lower upload performance from certain geographic areas. It is a best practice for uploading large objects, but it does not provide the same global acceleration benefits as S3 Transfer Acceleration.

Therefore, option C is the most appropriate choice for remediating the upload performance issue in this scenario.
