A Recovery Services vault protects 40 VMs by using one daily backup policy that retains recovery points for 7 days. One finance VM must keep daily recovery points for 30 days, but the other VMs should remain on the 7-day policy. What should the administrator do?

Edit the existing policy so all protected VMs inherit 30-day retention.

Changing the existing policy would affect every VM assigned to it, which breaks the requirement.

Move the finance VM to another resource group so it gets different retention automatically.

Resource group placement does not control Azure Backup retention behavior for protected VMs.

Apply a resource lock to the finance VM to preserve its recovery points longer.

Resource locks prevent management actions, but they do not change backup retention or policy behavior.

What does this AZ-104 question test?

Read the scenario before looking for a memorised answer.

What is the correct answer to this question?

The correct answer is: Create a second backup policy with 30-day retention and assign only the finance VM to it. — Azure VM backup retention is controlled by backup policy, not by resource group placement or locks. Because the finance VM needs a different retention schedule from the rest of the fleet, the correct approach is to create another backup policy with 30-day retention and assign that VM to it. That keeps the standard policy unchanged for the other VMs and cleanly separates the special retention requirement. Why others are wrong: Editing the existing policy would force every VM onto the longer retention period, which is not allowed by the scenario. Resource groups do not influence Azure Backup retention. A resource lock can prevent deletion or modification of the VM, but it does not extend backup recovery points. The decisive concept is that separate backup requirements usually mean separate policies.
