DP-300 Practice Question: Plan and configure a high availability and disaster recovery environment
Your company has an Azure SQL Managed Instance in the General Purpose tier. You need to configure a failover group for disaster recovery. The secondary managed instance must be in a different region and must also be used for read-only workloads. During a failover, you want to minimize data loss. Which configuration 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
✓
Create a failover group and configure the secondary instance to allow read-only connections.
Failover groups for Azure SQL Managed Instance allow you to configure the secondary instance to allow read-only connections, enabling it to serve read-only workloads. This minimizes data loss by using automatic replication with a Recovery Point Objective (RPO) of less than 1 second. Option A (zone redundancy) provides high availability within a region, not disaster recovery across regions. Option C (log shipping) is not a built-in feature for managed instances and does not support automatic failover. Option D (active geo-replication) is not supported for managed instances; failover groups are the recommended solution.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Enable zone redundancy on the primary and secondary instances.
Why it's wrong here
Zone redundancy provides HA within a region, not DR across regions.
- ✓
Create a failover group and configure the secondary instance to allow read-only connections.
Why this is correct
Failover groups support readable secondary and minimize data loss.
- ✗
Configure log shipping between the primary and secondary instances.
Why it's wrong here
Log shipping is not a built-in feature of Azure SQL Managed Instance.
- ✗
Use active geo-replication instead of a failover group.
Why it's wrong here
Active geo-replication is not supported for managed instances.
