DP-300 Practice Question: Plan and configure a high availability and disaster recovery environment
Which TWO of the following are valid reasons to use zone-redundant configuration for Azure SQL Database? (Choose 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
✓
Protection against a single availability zone failure within a region.
Zone-redundant configuration for Azure SQL Database replicates databases across multiple availability zones within the same region, providing protection against a single zone failure (option C) and offering higher availability than a single-zone deployment (option E). Option A is incorrect because zone redundancy does not reduce read latency; that is achieved by geo-replication or read scale-out. Option B is incorrect because automatic failover to a paired region is a feature of geo-redundant disaster recovery, not zone redundancy. Option D is incorrect because zone redundancy does not protect against a full regional disaster; it only protects within a region.
