AZ-104 Question 139
Single answerYou are an Azure Administrator managing a Windows Server VM named 'ProdVM' in the East US region under subscription A and resource group RG-Prod. Your organization wants to move 'ProdVM' to West Europe under subscription B and a new resource group RG-New, while minimizing downtime and verifying functionality before finalizing the move. Which approach should you use?
- A
Use the 'Move' option in the Azure portal to directly transfer the VM between subscriptions and regions without additional services
- B
Use Azure Resource Mover to replicate the VM to West Europe, perform a test migration, and then finalize the move
- C
Deallocate the VM and manually copy its VHD to a new storage account in West Europe, then create a new VM in the new subscription
- D
Stop the VM, change the subscription and region settings in the VM configuration blade, and start it again
Show answer and explanation
Correct answer: B
Explanation
Azure Resource Mover provides a streamlined way to move resources between regions with minimal downtime, including a test migration stage to verify the VM’s functionality before completing the final move.
- A. Incorrect.
The built-in 'Move' feature in the Azure portal can move resources between subscriptions or resource groups, but it does not provide an end-to-end replication or test functionality for changing regions. It also typically does not minimize downtime in a controlled way.
- B. Correct.
Azure Resource Mover is designed for cross-region moves, allowing replication, test migrations, and then a final move, which helps minimize downtime and ensures you can validate the VM before committing changes.
- C. Incorrect.
Manually copying the VHD and recreating the VM works but is more complex. It does not offer a simple test migration path, and requires additional effort to set up the new VM with the same configurations in the target region.
- D. Incorrect.
Region settings cannot simply be edited in the VM configuration blade. You would have to recreate the VM, which increases downtime and does not provide a test migration option.
