DP-300 Practice Question: Plan and configure a high availability and disaster recovery environment
Your company runs a global e-commerce application using Azure SQL Database in the West Europe region. You need to implement a solution that provides automatic failover and allows the secondary region to be used for read-only queries during normal operations. The secondary must be in a different region. Which configuration meets these requirements?
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 an auto-failover group with a secondary in West US and use the secondary as readable.
An auto-failover group with a readable secondary in a different region provides automatic failover and allows read-only queries on the secondary during normal operations. Option C is incorrect because active geo-replication requires application-level failover logic, which is not automatic, and thus does not meet the requirement for automatic failover. Option A is incorrect because read scale-out is limited to the same region. Option D is incorrect because geo-restore is a backup/restore mechanism, not a continuous replication solution.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Enable read scale-out on the primary database.
Why it's wrong here
Read scale-out only uses local replicas, not cross-region.
- ✓
Create an auto-failover group with a secondary in West US and use the secondary as readable.
Why this is correct
Correct. Auto-failover groups provide automatic failover and support readable secondaries, meeting both requirements.
- ✗
Configure active geo-replication to a secondary server in West US and implement application-level failover logic.
Why it's wrong here
Incorrect. Active geo-replication creates a readable secondary but does not provide automatic failover; it requires application-level logic to initiate failover, which does not meet the 'automatic failover' requirement.
- ✗
Configure geo-restore with a recovery point objective of 1 hour.
Why it's wrong here
Geo-restore is not for continuous read access.
