DP-300 Practice Question: Plan and configure a high availability and disaster recovery environment
You have an Azure SQL Managed Instance configured with failover groups to a secondary region. During a disaster, you perform a planned failover to the secondary region. After the primary region recovers, you want to fail back. What should you do first?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Perform a planned failover from the current primary to the original primary.
After a planned failover to a secondary region, the secondary region becomes the primary. To fail back to the original primary region, you perform another planned failover from the current primary (the former secondary) to the original primary. This is the only way to switch roles back without data loss. Option B correctly identifies this process. Option A is wrong because you cannot add a new secondary replica while failover groups are already in place; failover groups manage replicas. Option C is wrong because geo-replication is not used with managed instance failover groups; failover groups handle replication. Option D is wrong because you cannot directly configure the original primary as a secondary; you must perform a failover.
