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 Managed Instance that hosts a critical OLTP workload. The primary instance is deployed in West Europe. You need to ensure that failover to a secondary region occurs automatically when the primary becomes unavailable due to a regional outage, and that the secondary database is readable during normal operations. You also want to minimize storage costs. What should you configure?
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 between the primary and a secondary managed instance in a paired region.
Failover groups for Azure SQL Managed Instance provide automatic failover to a secondary instance in a paired region, and the secondary is readable for read-only workloads, meeting the requirements. Option B is incorrect because 'auto-failover groups' is a term used for Azure SQL Database, not SQL Managed Instance; SQL MI uses failover groups, which also provide automatic failover. Option A is incorrect because geo-zone-redundant storage is a storage redundancy option, not a disaster recovery configuration for SQL MI. Option C is incorrect because active geo-replication is available for Azure SQL Database, not 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.
- ✗
Deploy a secondary instance using a Bicep template with geo-zone-redundant storage.
Why it's wrong here
Bicep is for deployment, not DR; geo-zone-redundant storage protects data but does not provide automatic failover.
- ✗
Implement auto-failover groups with a readable secondary in another region.
Why it's wrong here
While auto-failover groups exist for SQL Database, for SQL Managed Instance the feature is simply called failover groups, which already provide automatic failover.
- ✗
Configure active geo-replication between two managed instances.
Why it's wrong here
Active geo-replication is not supported for SQL Managed Instance; failover groups are used instead.
- ✓
Create a failover group between the primary and a secondary managed instance in a paired region.
Why this is correct
Failover groups for SQL Managed Instance provide automatic failover and a readable secondary replica, meeting all requirements.
