You have an Azure SQL Managed Instance. You need to implement a disaster recovery solution that provides automatic failover with an RTO of less than 1 hour. Which THREE actions should you take?
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 secondary Managed Instance in a different Azure region.
To achieve automatic failover with an RTO under 1 hour for Azure SQL Managed Instance, you need a secondary instance in a different region (B), a failover group for automatic failover (C), and the Business Critical service tier which supports failover groups (E). Zone redundancy (A) provides high availability within a region, not disaster recovery across regions. Geo-replication (D) is not supported on Managed Instance; failover groups are the correct mechanism.
