DP-300 Practice Question: Plan and configure a high availability and disaster recovery environment
You need to ensure high availability for an Azure SQL Database in the Business Critical service tier. Which feature provides the fastest failover within the same region?
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
✓
Built-in Always On availability groups
The Business Critical service tier uses Always On availability groups with synchronous replication, providing automatic and fast failover within the same region. Option B (Zone-redundant configuration) adds zone resilience but does not provide faster failover within a zone. Option C (Read scale-out) is for read-only workloads and does not provide failover. Option D (Active geo-replication) is for cross-region failover and has a higher RTO.

- ✓
Built-in Always On availability groups
Why this is correct
Provides synchronous replication and automatic failover.
- ✗
Zone-redundant configuration
Why it's wrong here
Improves resilience but not the primary failover mechanism within the tier.
- ✗
Read scale-out
Why it's wrong here
Offloads read workloads, not a failover feature.
- ✗
Active geo-replication
