Which TWO statements about Azure SQL Database zone-redundant configuration are true? (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
✓
It can be enabled during database creation or by updating an existing database.
Options B and D are correct. Zone-redundant configuration can be enabled during database creation or by updating an existing database (B), and it provides resilience within a single Azure region across multiple availability zones (D). Option A is incorrect because zone-redundant configuration does not require a failover group; failover groups are used for geo-replication, not for zone redundancy. Option C is incorrect because zone-redundant configuration is available in both the General Purpose and Business Critical service tiers. Option E is incorrect because the cost impact varies by tier: General Purpose tier does not incur additional cost for zone redundancy, while Business Critical does; thus, the blanket statement that it always incurs additional cost is false.
