DP-300 Practice Question: Plan and configure a high availability and disaster recovery environment
You are planning a disaster recovery strategy for an Azure SQL Database that is part of a failover group. The application requires that after a failover, the database is accessible with minimal downtime and without data loss. Which THREE components are essential for this configuration? (Select three.)
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
✓
Secondary database in a paired region with data synchronization
A secondary database in a paired region with data synchronization ensures that data is replicated to another region, enabling failover with minimal data loss. Option C is correct: The failover group listener endpoint provides a constant connection string that automatically routes to the current primary database, ensuring application connectivity after failover. Option E is correct: The failover group configured between primary and secondary servers orchestrates the replication and automatic failover process. Option A is incorrect: Geo-redundant backup storage is for point-in-time restore, not for failover. Option D is incorrect: Azure Traffic Manager with priority routing is not needed when using failover groups; the failover group listener handles routing.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Geo-redundant backup storage
Why it's wrong here
Backups are not used during failover; they are for point-in-time restore.
- ✓
Secondary database in a paired region with data synchronization
Why this is correct
The secondary must be synchronized to ensure no data loss.
- ✓
Failover group listener endpoint
Why this is correct
Provides a constant connection string that automatically points to the current primary.
- ✗
Azure Traffic Manager with priority routing
Why it's wrong here
Failover group listener already handles routing.
- ✓
Failover group configured between primary and secondary servers
