DP-300 Practice Question: Plan and configure a high availability and disaster recovery environment
You have an Azure SQL Managed Instance configured with an auto-failover group between two regions. You need to ensure that client applications can automatically connect to the secondary instance after a failover without changing connection strings. 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
✓
Use the failover group listener endpoint in the connection string.
The failover group listener provides a read-write listener endpoint that automatically points to the current primary. Option B is wrong because a Traffic Manager profile would require manual intervention. Option C is wrong because an Application Gateway does not provide automatic failover redirection. Option D is wrong because a load balancer does not handle failover group redirection.
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 failover group listener endpoint in the connection string.
Why this is correct
The listener automatically routes to the current primary.
- ✗
Set up a load balancer with health probes.
Why it's wrong here
Load balancers are not designed for SQL failover redirection.
- ✗
Deploy an Application Gateway with backend pools for each region.
Why it's wrong here
Application Gateway does not provide automatic failover for SQL connections.
- ✗
Configure a Traffic Manager profile with endpoint monitoring.
Why it's wrong here
Traffic Manager adds complexity and does not integrate with failover groups natively.
