AZ-104 Practice Question 27: Move VM Across Regions
Microsoft Azure Administrator Associate (AZ-104) · Test 3 · question 7 of 10
An application's users have all relocated to the Midwest. The supporting virtual machines, their managed disks, NICs, network security groups, and an internal load balancer currently run in West US, and the business wants them running in Central US instead. The team wants to validate the move and be able to discard it if the test goes badly.
What should you use?
Show answer and explanation
Answer:
Resource Mover exists for this job: it "helps you to move Azure resources between Azure regions," provides "an easy way to identify dependencies across resources you want to move," and supports precisely this inventory: "Azure VMs and associated disks", NICs, virtual networks, NSGs, and "internal and public load balancers". It also matches the rehearsal requirement: "you can try out a move and then discard it if you don't want to do a full move," and it can clean up the source-region resources afterwards.
Option A misunderstands what the Move action does. Moving a resource to another resource group or subscription changes which container it belongs to; it never changes the region the resource runs in, and a resource group's location only determines where its metadata is stored.
Option B fails at deployment time. Resource Manager is explicit: "if you try to update the location or type of an existing resource, the deployment fails with an error. Instead, deploy a new resource with the location or type that you need."
Option D repurposes a disaster-recovery feature. Cross Region Restore restores backups into the *paired* secondary region of the vault, which is not a region you choose, and it produces restored copies rather than a validated, reversible migration of the VMs and their networking.
