AZ-104 Question 285
Single answerYour primary region has experienced a critical outage, making it completely unavailable. You need to bring your virtual machines and applications online in the secondary region using Azure Site Recovery as quickly as possible. Which failover method must you initiate in the Recovery Services vault to recover your workloads?
- A
Perform a Test Failover in the secondary region
- B
Perform an Unplanned Failover in the secondary region
- C
Perform a Planned Failover from the primary region
- D
Create a new replication policy in the secondary region
Show answer and explanation
Correct answer: B
Explanation
When the primary region is completely offline, a planned failover is impossible because it cannot synchronize final changes from the primary region. Therefore, an unplanned failover is the correct method to bring your VMs and applications online in the secondary region under these circumstances.
- A. Incorrect.
While a Test Failover validates your disaster recovery setup, it does not bring the production environment fully online in the secondary region when the primary site is down.
- B. Correct.
An Unplanned Failover is used when the primary region is unavailable. It brings your workloads online in the secondary region without attempting to synchronize last-minute changes from the primary site.
- C. Incorrect.
A Planned Failover requires the primary region to be accessible in order to replicate any final data changes before switching over. It is not feasible if the primary region is offline.
- D. Incorrect.
Creating or modifying replication policies is an initial configuration step, not the action taken to recover your workloads during an outage.
