DP-300 Plan and implement data platform resources Practice Question
You have an Azure SQL Database in the General Purpose tier. You need to implement high availability with automatic failover to a secondary database in a different Azure region. The solution must provide an RPO of 5 seconds and RTO of 1 hour. Which TWO components must you configure? (Select TWO.)
⚠ Common exam trap
It's easy for candidates to confuse the auto-failover group (Option E) as a standalone component, not realizing it requires a pre-configured secondary database via active geo-replication to function, and they may incorrectly assume Business Critical tier (Option A) is necessary for cross-region failover when General Purpose with geo-replication suffices.
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
✓
Configure active geo-replication
Active geo-replication (Option C) creates a readable secondary database in a different Azure region, supporting cross-region disaster recovery. When combined with an auto-failover group, it provides automatic failover with an RPO of 5 seconds and an RTO of 1 hour, meeting the requirements for a General Purpose tier database.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Change the service tier to Business Critical
Why it's wrong here
Business Critical is not required; General Purpose supports geo-replication.
- ✗
Enable zone redundancy on the primary database
Why it's wrong here
Zone redundancy is within region, not cross-region DR.
- ✓
Configure active geo-replication
Why this is correct
Active geo-replication provides asynchronous replication to a secondary region.
- ✓
Create a secondary database in a different Azure region
Why this is correct
A secondary database is required for geo-replication.
- ✗
Create an auto-failover group
Why it's wrong here
Failover group alone does not set up replication; it requires geo-replication.
