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

You manage a critical SQL Server on Azure Virtual Machine running SQL Server 2019. The VM is in a single availability set. You need to ensure automatic failover in case of a zone-level failure. What should you implement?

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

Deploy the VM in an availability zone and configure an Always On availability group with a secondary replica in another zone.

Deploying the VM in an availability zone and configuring an Always On availability group with a secondary replica in another zone ensures automatic failover if the primary zone fails. Option B is incorrect because an availability set only protects against failures within a datacenter, not zone-level failures. Option C is incorrect because geo-replication is designed for regional failure recovery, not zonal failover. Option D is incorrect because automated backups with long-term retention do not provide failover capabilities.

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 the VM in an availability zone and configure an Always On availability group with a secondary replica in another zone.

    Why this is correct

    Zone-redundant deployment provides automatic failover for zone failures.

  • Place the VM in an availability set.

    Why it's wrong here

    Availability sets protect against rack failures, not zone failures.

  • Enable geo-replication to another Azure region.

    Why it's wrong here

    Geo-replication protects against region failure, not zone failure.

  • Configure automated backups with long-term retention.

    Why it's wrong here

    Backups do not provide automatic failover.
