AZ-104 Question 284
Single answerDuring a regional outage in your primary Azure region, you need to fail over your replicated virtual machines to the secondary region using Azure Site Recovery as quickly as possible. Connectivity to the primary region is lost, and you want to ensure minimal additional data loss. Which failover method should you choose first to bring your application online in the secondary region?
- A
Test Failover
- B
Planned Failover
- C
Unplanned Failover
- D
Failover with latest processed data
Show answer and explanation
Correct answer: C
Explanation
When the primary region is unexpectedly offline, a Planned Failover is not possible because it relies on gracefully shutting down workloads on the primary side. An Unplanned Failover is the appropriate choice, as it uses the most recently replicated data and does not require connectivity with the primary region.
- A. Incorrect.
Test Failover is used to validate the recovery scenario in an isolated environment without impacting production workloads, rather than performing a real production failover.
- B. Incorrect.
Planned Failover is utilized when you have connectivity with the primary region and can shut down workloads gracefully, ensuring no data loss. It is not suitable when the primary region is completely offline.
- C. Correct.
Unplanned Failover is the correct choice in a scenario where the primary region is offline or unreachable. This operation brings up the secondary region using the latest replicated data, anticipating some data loss if final replication from the primary cannot occur.
- D. Incorrect.
Failover with latest processed data is an option that exists within the failover settings, but the method is still categorized under Unplanned or Planned failover. Simply choosing 'Failover with latest processed data' alone does not initiate the correct failover mode when the primary region is offline.
