Q1. What are the differences between Azure Service Manager and Azure Resource Manager?

Ans: ASM uses XML REST API and ARM uses JSON REST API. In ASM, it is difficult to delete the resources which have been created and in ARM we can easily group to delete the resources. ASM supports only specific PaaS workloads and in ARM it supports all workloads of PaaS.

2. Provide few Advantages of Resource Group?

Ans: In Resource Manager, we could easily maintain all the services which have been created under a single resource group which could be segregated by application wise if required. If we required deleting the services, instead of deleting one by one, we can able to delete all the services in a single click by deleting the resource group. To provide a permission of individual service, we could provide a permission to the resource group, whereas provided permission will be implemented to all the services.

3. Could we able to move the services from one Resource Group to Another?

Ans: Yes, we could be able to move the services from One resource group to another if that subscription has a permission to do it with respective services.

4. Is that possible to migrate the services from one Subscription to Another Subscription?

Ans: Yes, it could be possible to move the services from one to another only if both the subscriptions are available in the same Azure Active Directory Tenant.

5. Could we able to move Express Route / Managed Disks / Application Gateway to another subscription or Resource Group?

Ans: No, we couldn’t be able to since these are dependency services.

6. Is there any possibility to change an Instance Size once the Virtual Machine has been created?

Ans: Yes, we can. By navigating to Size under settings option, we could be able to change the instance type to higher or lower configurations.

7. If this CIDR 10.0.0.0/16 is provided in the Address Space under a Virtual Network, how many subnets we could be able to create?

Ans: 256 Subnets can be created.

8. What is Gateway Subnet?

Ans: If one Virtual Network needs to establish a communication to another, Gateway Subnet is being required.

9. What is the best solution to handle application performance without manual intervention?

Ans: We could provision a Virtual Machines under VM Scale Sets by defining the policy which would handle loads of application by provisioning a new Virtual Machine automatically.

10. Can we able to restrict database port number to communicate only to Application Server?

Ans: Yes, that could be possible in Network Security Group.

11. If I have more than 3 application servers, I require the database port number needs to communicate to all the 3 application servers. How could be possible?

12. What are the types of Virtual Network Gateway?

Ans: VPN & Express Route. In VPN, there is Site to Site, Multi-Site & Point to Site.

13. In AWS we are using Elastic Beanstalk for deploying an application automatically. What is the similar feature provided in Azure?

Ans: Under App Services, we could use WebApps for deploying an application automatically.

14. If I need to execute the code without a server, what is the best solution does Azure offering?

Ans: Azure Functions could be used to execute the code with serverless.

Ans: No, Azure Internal Load Balancer supports only Private IP address and we couldn’t be able to assign the Public IP / DNS name.

20. What is the best feature is used for handling failover between regions in Azure?

Ans: Using Traffic Manager, we could handle failover within the regions.

21. Could I able to use same Virtual Network Gateway for both VPN & Express Route?

Ans: No, Virtual Network Gateway needs to be created separately for different types.

22. I have an application running in my On-Premises and I had backed up the environment to Azure East US region. If On-Premises application failed to access, could I able to switch to Azure environment?

Ans: Yes, using Site Recovery, we could handle fail over and fail back to On-Premises and Azure environment.

23. Could I able to maintain/manage my On-Premises Active Directory using Azure Active Directory?

Ans: Yes, using Azure AD Connect Health we could monitor the actions which are performed in your On-Premises Active Directory.

Ans: Yes, we could able to do that by creating separate Load Balancer Rules in Azure.

25. In AWS, maintenance is handled by Availability Zone wise. Any Idea about maintenance in Azure?

Ans: In Azure, maintenance is handled by region wise.

26. Could I able to use custom Images / Private Images for VM Scale Sets using Portal?

Ans: No. At present, there is no option to use private Images in VM Scale Sets using Portal and same could be achieved in CLI / PowerShell / Template.

27. Is there any possibility to add more than one Private IP Address for single Virtual Machine?

Ans: Yes. By adding NIC, we could able to attach more than one Private IP Address for one Virtual Machine.

28. I have 10 Virtual Machines and I would require a common file sharing between all these Virtual Machines. What will be the best feature recommended to achieve this?

Ans: Azure File System could be used as a common repository which shares the data with all these Virtual Machines using SMB, NFS & FTPS.

29. Does Oracle as a Database Service Available in Azure?

Ans: No, Azure doesn’t have a Database as a Service for Oracle.

30. If I want to distribute a Website which is available in Storage Container without replicating, what is the recommended solution?

Ans: Using CDN Profiles, we can distribute the content across the globe and latency will be reduced by delivering the content from Edge Location instead of reaching the original server.

31. Does Geo Replication support in PostgreSQL Database service which is offered by Azure?

Ans: At present, there is no support on Geo-Replication for PostgreSQL and it may be in Azure Road Map.

32. If the transaction between my Application Server and Database Server are delayed due to Disk IOPS. What is the solution to avoid this issue?
