DP-300 Practice Question: Plan and configure a high availability and disaster recovery environment
You are migrating an on-premises SQL Server database to Azure SQL Managed Instance. The database is 500 GB and requires a disaster recovery solution with an RPO of 15 seconds and automatic failover to a secondary region. Which configuration meets these requirements?

Correct answer & explanation
✓
Create an auto-failover group with a secondary instance in a paired region using synchronous replication.
Auto-failover groups with a secondary instance in a paired region using synchronous replication meet the requirements for automatic failover and an RPO of 15 seconds for Azure SQL Managed Instance. Option A is incorrect because geo-redundant backup storage and geo-restore do not provide automatic failover or a low RPO. Option B is incorrect because active geo-replication is not supported for SQL Managed Instance; it is used for Azure SQL Database. Option C is incorrect because log shipping is not supported for SQL Managed Instance.
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 geo-redundant backup storage and configure geo-restore.
Why it's wrong here
Geo-restore does not provide automatic failover and RPO is higher.
- ✗
Configure active geo-replication to a secondary instance in another region.
Why it's wrong here
Active geo-replication is not supported for Managed Instance.
- ✗
Set up log shipping to a secondary instance in another region.
Why it's wrong here
Log shipping cannot meet the 15-second RPO because it relies on scheduled transaction log backup and restore cycles, typically running every few minutes, not seconds. It also lacks automatic failover; a manual or scripted process is required to bring the secondary online. This option is tempting because log shipping is a familiar on-premises DR technique that replicates to a secondary region, and it would be correct if the RPO were minutes rather than seconds and manual failover were acceptable.
- ✓
Create an auto-failover group with a secondary instance in a paired region using synchronous replication.
Why this is correct
Auto-failover groups support automatic failover and synchronous replication for low RPO.
