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

You are designing a high availability solution for an Azure SQL Database that supports an online transaction processing (OLTP) workload. The database must be available with an SLA of 99.995% and must withstand a regional outage. Which configuration should you choose?

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

Business Critical tier with zone-redundancy and a failover group with geo-replication.

The Business Critical tier with zone redundancy provides a 99.995% SLA within a region. However, to withstand a regional outage, you need geo-replication. A failover group with active geo-replication ensures that if the primary region fails, you can fail over to a secondary region. Option A (Business Critical zone-redundancy only) protects against zone failures within a region but not a full regional outage. Option B (General Purpose with active geo-replication) has a lower SLA (99.99%) and does not meet the 99.995% requirement. Option C (Hyperscale with geo-replication) also has a lower SLA (99.95%) than required.

Answer analysis

Option-by-option breakdown

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

  • Business Critical tier with zone-redundancy only.

    Why it's wrong here

    Does not protect against a regional outage.

  • General Purpose tier with active geo-replication to a secondary region.

    Why it's wrong here

    General Purpose SLA is 99.99%.

  • Hyperscale tier with geo-replication.

    Why it's wrong here

    Hyperscale SLA is 99.95%.

  • Business Critical tier with zone-redundancy and a failover group with geo-replication.

    Why this is correct

    Business Critical with zone-redundancy provides 99.995% SLA and geo-replication protects against regional failure.
