DP-300 Practice Question: Plan and configure a high availability and disaster recovery environment
You are designing a disaster recovery solution for a mission-critical Azure SQL Database that requires a Recovery Point Objective (RPO) of 5 seconds and a Recovery Time Objective (RTO) of 30 seconds. Which configuration should you recommend?
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
✓
Failover group with automatic failover and data loss threshold of 5 seconds.
Failover groups with automatic failover policy can achieve an RPO of 5 seconds (when the data loss threshold is set to 5 seconds) and an RTO of approximately 30 seconds. Active geo-replication (Option B) requires manual failover, which cannot meet the 30-second RTO. Geo-restore (Option C) has an RPO of 1 hour and RTO of 12 hours. Zone-redundant databases (Option D) only protect against within-region failures, not region-level disasters.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Failover group with automatic failover and data loss threshold of 5 seconds.
Why this is correct
Meets the required RPO and RTO.
- ✗
Active geo-replication with manual failover.
Why it's wrong here
Manual failover increases RTO beyond 30 seconds.
- ✗
Geo-restore of automated backups.
Why it's wrong here
RPO of 1 hour and RTO of 12 hours.
- ✗
Zone-redundant database in the primary region.
Why it's wrong here
Does not protect against region failure.
