DP-300 Practice Question: Plan and configure a high availability and disaster recovery environment
Your company has an Azure SQL Database in the East US region. You need to configure a disaster recovery solution that provides a readable secondary in the West US region with an RPO of 5 seconds. The solution must support automatic failover from the application. 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 an auto-failover group with a secondary server in West US using synchronous replication.
Auto-failover groups with a secondary server in another region using synchronous replication can achieve an RPO of 5 seconds and support automatic failover from the application. Option A is wrong because zone-redundant replicas are in the same region and do not provide cross-region DR. Option B is wrong because geo-redundant backup storage and geo-restore are not for automatic failover and have a higher RPO. Option C is wrong because although active geo-replication provides a readable secondary, it does not support automatic failover; a group is needed.
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 zone-redundant replicas in the same region.
Why it's wrong here
Zone redundancy does not provide cross-region DR.
- ✗
Enable geo-redundant backup storage and perform geo-restore.
Why it's wrong here
Geo-restore has higher RPO and RTO.
- ✗
Configure active geo-replication to a secondary server in West US.
Why it's wrong here
Active geo-replication requires application-level failover logic.
- ✓
Create an auto-failover group with a secondary server in West US using synchronous replication.
Why this is correct
Auto-failover groups can achieve low RPO with synchronous replication.
