DP-300 Practice Question: Plan and configure a high availability and disaster recovery environment
Your company requires that all production databases in Azure SQL Database have an RPO of less than 5 seconds and an RTO of less than 1 minute during a regional outage. You need to recommend a high availability and disaster recovery solution. Which feature should you use?
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
✓
Auto-failover groups with active geo-replication
Auto-failover groups with active geo-replication provide the lowest RPO (typically <5 seconds) and RTO (under 1 minute) for regional outages by enabling continuous data synchronization and automated failover across paired regions. Option A is incorrect because zone-redundant configuration only protects against zonal failures within a single region, not a full regional outage. Option C is wrong because long-term retention backups are for archival purposes and have much higher RPO/RTO. Option D is incorrect because geo-restore from geo-redundant backups has an RPO of at least 1 hour and an RTO of several hours to days, failing to meet the strict requirements.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Zone-redundant configuration (Hyperscale service tier)
Why it's wrong here
Only protects within a region, not across regions.
- ✓
Auto-failover groups with active geo-replication
Why this is correct
Provides low RPO and RTO across regions.
- ✗
Long-term retention (LTR) backups
Why it's wrong here
LTR is for archival, not for fast DR.
- ✗
Geo-restore from geo-redundant backups
Why it's wrong here
RPO is typically 1 hour, and RTO is hours.
