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?

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.

- ✗
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.
