DP-300 Practice Question: Plan and configure a high availability and disaster recovery environment
You have an Azure SQL Database configured with a failover group that includes a secondary in another region. The primary region experiences a complete outage. You initiate a forced failover. After the outage is resolved, you want to bring the original primary back as a secondary without data loss. What should you do?
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
✓
Remove the original primary from the failover group, drop the database, and recreate it as a new secondary
After a forced failover, the original primary is in a failed state. To bring it back as a secondary without data loss, you must remove it from the failover group, drop the original database, and then add a new secondary database (which will be seeded from the current primary). This is the only method that ensures no data loss. Option A is incorrect because there is no 'az sql db failover-group re-sync' command. Option B is incorrect because active geo-replication is not required; failover groups automatically handle replication. Option C is incorrect because restoring from backup would not reflect changes made after the failover, resulting in data loss.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Use the 'az sql db failover-group re-sync' command to re-synchronize
Why it's wrong here
There is no such command; you must remove and recreate the secondary.
- ✗
Configure replication from the new primary to the old primary using active geo-replication
Why it's wrong here
Active geo-replication is separate from failover groups; mixing both is not supported.
- ✗
Restore the original primary from backup and re-add it to the failover group
Why it's wrong here
Restoring from backup will lose transactions that occurred after the failover, unless point-in-time is used, but it's not the standard procedure.
- ✓
Remove the original primary from the failover group, drop the database, and recreate it as a new secondary
Why this is correct
This is the recommended approach to rejoin a failed primary after a forced failover.
