DP-300 Practice Question: Plan and configure a high availability and disaster recovery environment
You manage an Azure SQL Database in the Business Critical service tier. The database must be highly available within a single region. Which TWO features contribute to this high availability?
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
✓
Multiple synchronous replicas (4 replicas)
The correct answers are B and E. In the Business Critical service tier, multiple synchronous replicas (at least 4) provide local high availability within a region. Additionally, enabling zone-redundant configuration distributes these replicas across availability zones within the same region, further improving availability. Options A and D (Active geo-replication and Auto-failover groups) are cross-region disaster recovery features and do not contribute to intra-region high availability. Option C (Always On availability groups) is the underlying technology for the replicas but is not a separate feature; the question asks for features that contribute to high availability, and the replicas themselves are the feature.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Active geo-replication
Why it's wrong here
For cross-region, not within region.
- ✓
Multiple synchronous replicas (4 replicas)
Why this is correct
Business Critical includes 4 replicas for HA.
- ✗
Always On availability groups
Why it's wrong here
Internal implementation, not a configurable feature.
- ✗
Auto-failover groups
Why it's wrong here
For cross-region failover.
- ✓
Zone-redundant configuration (when enabled)
Why this is correct
Provides resilience within a region across zones.
