DP-300 Practice Question: Plan and configure a high availability and disaster recovery environment
You are configuring a failover group for a pair of Azure SQL Managed Instances in different regions for disaster recovery. The primary instance experiences a regional outage. You need to ensure that after a forced failover, the secondary instance automatically becomes the primary without any manual intervention and that applications can connect using the same listener endpoint. What should you configure?
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
✓
Create a failover group with automatic failover policy and add the databases.
A failover group with automatic failover policy ensures that during a regional outage, the secondary database becomes the primary automatically and the listener endpoint remains unchanged. Option A is wrong because Azure Traffic Manager is not needed; the failover group listener provides the endpoint. Option B is wrong because 'enable auto-failover groups' is not a separate setting; a failover group with automatic failover policy is already the required configuration. Option C is wrong because active geo-replication does not provide a single listener endpoint and requires manual failover.
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 Azure Traffic Manager with priority routing to the secondary instance.
Why it's wrong here
Traffic Manager is not required; the failover group listener handles the endpoint.
- ✗
Enable auto-failover groups on the primary instance.
Why it's wrong here
Auto-failover groups are the correct mechanism, but the answer is incomplete without specifying the failover policy.
- ✗
Configure active geo-replication between the instances.
Why it's wrong here
Active geo-replication requires manual failover and does not provide a single listener endpoint.
- ✓
Create a failover group with automatic failover policy and add the databases.
Why this is correct
A failover group with automatic failover provides a listener endpoint and automatic failover during an outage.
