DP-300 Practice Question: Plan and configure a high availability and disaster recovery environment

You are designing a high availability and disaster recovery solution for an Azure SQL Managed Instance that hosts a mission-critical database. You need to ensure zero data loss during planned maintenance and automatic failover within 30 seconds. Additionally, you must protect against a regional outage with an RPO of 5 minutes and an RTO of 1 hour. Which TWO features should you implement? (Select two.)

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

Configure a failover group to a secondary region.

A failover group to a secondary region provides disaster recovery with an RPO of 5 minutes and RTO of 1 hour, meeting the regional outage requirements. Option D is correct because the Business Critical tier with zone redundancy offers zero data loss and automatic failover within 30 seconds for planned maintenance within a region. Option A is incorrect because long-term backup retention with geo-redundant storage does not provide automatic failover or meet the RPO/RTO targets. Option B is incorrect because active geo-replication is not supported for Azure SQL Managed Instance. Option E is incorrect because the General Purpose tier does not support zone redundancy, so it cannot meet the zero data loss and fast failover requirements.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

    Why it's wrong here

    Not supported for Managed Instance.

  • Configure a failover group to a secondary region.

    Why this is correct

    Provides cross-region DR with RPO of 5 minutes and RTO of 1 hour.

  • Deploy the instance in the Business Critical tier with zone redundancy.

    Why this is correct
