DP-300 Practice Question: Plan and configure a high availability and disaster recovery environment
Your company uses Azure SQL Managed Instance for a critical application. You need to meet a Recovery Point Objective (RPO) of 15 seconds and a Recovery Time Objective (RTO) of 30 seconds for planned maintenance. You also need to protect against a regional failure with an RPO of 5 minutes and an RTO of 1 hour. What combination of features should you use?

Correct answer & explanation
✓
Deploy the instance in the Business Critical tier with zone redundancy, and configure a failover group to a secondary region.
Business Critical tier with zone redundancy provides high availability within a region with an RPO of 0 and RTO of approximately 30 seconds for planned maintenance. Configuring a failover group to a secondary region provides disaster recovery with an RPO of 5 minutes and RTO of 1 hour. Option A is incorrect because active geo-replication is not supported for Azure SQL Managed Instance; failover groups are used instead. Option B is incorrect because General Purpose tier does not provide an RTO of 30 seconds for planned maintenance, and geo-redundant backup does not meet the required RPO and RTO for planned maintenance. Option C is incorrect because a failover group alone does not provide the sub-minute RTO needed for planned maintenance within the region.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Configure active geo-replication to a secondary region and use automatic failover.
Why it's wrong here
Active geo-replication is not supported for Managed Instance.
- ✗
Deploy in General Purpose tier with zone redundancy and geo-redundant backup.
Why it's wrong here
General Purpose tier does not support zone redundancy.
- ✗
Create a failover group to a secondary region and rely on that for both HA and DR.
Why it's wrong here
Failover group alone does not provide sub-minute RTO for planned maintenance.
- ✓
Deploy the instance in the Business Critical tier with zone redundancy, and configure a failover group to a secondary region.
Why this is correct
Zone redundancy provides HA within region; failover group provides DR across regions.
