DP-300 Practice Question: Plan and configure a high availability and disaster recovery environment
You manage a mission-critical Azure SQL Database in the East US region. The database uses the Business Critical service tier with zone-redundant high availability enabled. You need to ensure that if an entire Azure region fails, the database can be failed over to a secondary region with minimal data loss. What should you implement?
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
✓
Enable active geo-replication to a secondary server in a paired region.
Active geo-replication provides near-real-time asynchronous replication to a secondary region, and with Business Critical, you can configure a readable secondary that can be failed over manually or automatically with minimal data loss. Option A is wrong because failover groups are built on top of geo-replication but do not guarantee minimal data loss by themselves; they rely on the replication mode. Option B is wrong because auto-failover groups include geo-replication but the question asks for the specific feature to implement. Option D is wrong because zone redundancy protects against zonal failures within a region, not regional failures.
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 auto-failover groups with read-write failover policy.
Why it's wrong here
Auto-failover groups require geo-replication; the specific feature is geo-replication itself.
- ✗
Configure a failover group with the secondary in a different Azure region.
Why it's wrong here
Failover groups use geo-replication but the question asks for the feature to implement for minimal data loss.
- ✓
Enable active geo-replication to a secondary server in a paired region.
Why this is correct
Active geo-replication provides asynchronous replication to a secondary region, enabling manual or automatic failover with minimal data loss.
- ✗
Deploy zone-redundant configuration in East US 2.
Why it's wrong here
Zone redundancy protects against zonal failures, not regional outages.
