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

Which TWO of the following are benefits of using Azure SQL Database failover groups compared to active geo-replication alone?

⚠ Common exam trap

Many candidates confuse the features of active geo-replication (like readable secondaries and manual failover) with the unique benefits of failover groups, which are specifically the ability to fail over multiple databases as a group and the automatic failover based on a grace period.

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

Failover of multiple databases in a single group.

Failover groups extend active geo-replication by allowing you to manage failover for a group of databases as a single unit. This simplifies the failover process when you have multiple databases that must be failed over together to maintain application consistency. Option B is correct because failover groups support the coordinated failover of multiple databases, which active geo-replication alone does not.

Answer analysis

Option-by-option breakdown

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

  • Support for manual failover.

    Why it's wrong here

    Incorrect: Both support manual failover.

  • Failover of multiple databases in a single group.

    Why this is correct

    Correct: Failover groups allow coordinated failover of multiple databases.

  • Readable secondary replicas for read-scale workloads.

    Why it's wrong here

    Incorrect: Both support readable secondaries.

  • Automatic failover based on the grace period.

    Why this is correct

    Correct: Failover groups support automatic failover; active geo-replication requires manual failover.

  • Synchronous data replication to the secondary.

    Why it's wrong here

    Incorrect: Both use synchronous replication for the secondary.
