Question 490
A regulated app needs a disaster-recovery drill but production traffic must remain on the original VM. What Site Recovery feature should be used?
Explanation
Correct Answer
Azure Site Recovery test failover creates test VM copies from a selected recovery point in the chosen recovery-region network without modifying the ongoing replication or automatically switching production traffic. For this regulated application, select an isolated recovery-test VNet, verify that DNS and application dependencies do not collide with production, and exercise realistic recovery checks there. Capture evidence of service functionality and recoverability, then use Cleanup test failover to remove temporary drill resources. Avoid treating success in an isolated VM as proof that customer traffic was cut over; testing and production failover are different, intentionally separate operations.
Incorrect Answers
Checking replication health and the selected recovery point before running a disaster-recovery exercise is a sensible preparatory safety measure. It helps avoid validating an outdated or unavailable replica, but it is not the Site Recovery feature that makes a test run separate from production. A normal unplanned failover could also begin with healthy replication and yet redirect service traffic; that would violate the no-production-interruption requirement. Choose the explicit test-failover operation with an isolated target network for the drill, then record observations and perform the test-failover cleanup.
An alert severity classification can indicate potential protection trouble, and a successful restore test is better evidence that recovery mechanisms actually operate. Those are important observations for backup and disaster-recovery governance, but they do not choose the Site Recovery operation needed for a non-disruptive drill. In the scenario the team needs to create recovery-region test VMs while production traffic continues to flow to the original service. A verified action alert by itself does not create an isolated replica or validate application login, network dependencies and cleanup; use test failover for that.
Verifying that the source and target regions, protected VM disks, replication support and target resources are compatible is an important prerequisite for any real or test failover. But it cannot by itself prevent a production cutover when an engineer selects the wrong operation. The requested feature must use an isolated test workflow that preserves the original running production VM and continued replication. Confirm prerequisites, then deliberately run Site Recovery Test Failover against a separate network rather than a planned or unplanned production failover, and clean up the created test resources afterward.
Mapping the target VNet, subnet, DNS services and application security controls is necessary to make a recovered instance functional. If those mappings point the drill into the production network without isolation, the test VM might collide with running endpoints or duplicate host identities. Network preparation is therefore part of safe test execution but not a standalone substitute for the test-failover operation. Select a distinct, controlled test network matching required application dependencies, run the drill, validate access and cleanup; retain the original customer traffic path rather than routing it to test VMs.
