DP-300 Practice Question: Plan and configure a high availability and disaster recovery environment
You are designing a disaster recovery plan for an Azure SQL Database that supports an e-commerce application. The application requires an RPO of 15 seconds and an RTO of 1 hour during a regional outage. Which solution should you recommend?

Correct answer & explanation
✓
Deploy active geo-replication to a secondary region and automate failover
Deploy active geo-replication to a secondary region and automate failover. Active geo-replication provides an asynchronous secondary replica in a different region with an RPO of up to 5 seconds, meeting the 15-second requirement. By automating failover (e.g., via Azure PowerShell, CLI, or Azure Automation), the RTO can be minimized to under 1 hour. Option A, creating a failover group with automatic failover, also uses geo-replication but the automatic failover policy may introduce additional detection time, making it harder to guarantee an RTO of exactly 1 hour. Additionally, failover groups are designed for managing multiple databases, adding unnecessary complexity for a single database. Option C, long-term backup retention and restore, has an RPO of hours, not seconds. Option D, zone-redundant availability, protects against zone failures within a single region, not a regional outage.
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 automatic failover policy
Why it's wrong here
Failover groups with automatic failover have an RTO of 1 hour, which meets the requirement, but the question asks for a recommendation; active geo-replication is more flexible for custom automation.
- ✓
Deploy active geo-replication to a secondary region and automate failover
Why this is correct
Active geo-replication provides low RPO and manual failover that can be automated to meet RTO.
- ✗
Use long-term backup retention and restore in another region
Why it's wrong here
Restoring from backups cannot achieve 15-second RPO.
- ✗
Configure zone-redundant availability for the database
Why it's wrong here
Zone redundancy protects within a region, not across regions.
