DP-300 Plan and implement data platform resources Practice Question
You are tasked with designing a disaster recovery plan for an Azure SQL Database. The database is mission-critical and must have a Recovery Point Objective (RPO) of 5 seconds and a Recovery Time Objective (RTO) of 30 minutes in case of a regional failure. Which configuration should you implement?
⚠ Common exam trap
Candidates often confuse zone-redundant configuration (which only protects against zone failures within a region) with active geo-replication (which protects against a full regional outage), leading them to select option C despite the requirement for regional disaster recovery.
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
✓
Active geo-replication with failover group
Active geo-replication with failover groups is the correct choice because it provides a continuous, synchronous replication mechanism that can achieve an RPO of 5 seconds and an RTO of 30 minutes during a regional failure. The failover group automates the process of failing over to a readable secondary database in a paired region, meeting both the stringent RPO and RTO requirements without manual intervention.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Long-term backup retention
Why it's wrong here
For archival, not DR.
- ✗
Automated backups with geo-restore
Why it's wrong here
Geo-restore RPO is 1-5 minutes, RTO is 12 hours.
- ✗
Zone-redundant configuration
Why it's wrong here
Protects within region, not cross-region.
- ✓
Active geo-replication with failover group
Why this is correct
Provides low RPO and fast RTO.
