DP-300 Plan and implement data platform resources Practice Question
You are designing a disaster recovery solution for an Azure SQL Database in the Business Critical tier. You require automatic failover to a secondary region with zero data loss. Which configuration should you use?
⚠ Common exam trap
Many candidates confuse active geo-replication with failover groups, assuming manual failover can achieve zero data loss, but active geo-replication uses asynchronous replication by default and does not support automatic failover with zero RPO.
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 a failover group with the Business Critical tier.
The Business Critical tier in Azure SQL Database supports failover groups, which provide automatic failover across regions with zero data loss by using synchronous replication at the primary region and asynchronous replication to the secondary region. Failover groups ensure that all committed transactions are preserved during a failover, meeting the zero data loss requirement for disaster recovery.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Create a failover group with the Business Critical tier.
Why this is correct
Failover groups on Business Critical provide synchronous replication and automatic failover.
- ✗
Configure geo-replication between two servers.
Why it's wrong here
Geo-replication is asynchronous, risk of data loss.
- ✗
Enable read scale-out in a secondary region.
Why it's wrong here
Read scale-out does not provide failover.
- ✗
Use active geo-replication with manual failover.
Why it's wrong here
Active geo-replication is asynchronous.
