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

Which TWO disaster recovery options are available 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

Auto-failover groups.

Active geo-replication and auto-failover groups are the two primary disaster recovery options for Azure SQL Database. Active geo-replication provides asynchronous replication of a database to a secondary region, while auto-failover groups extend this by allowing failover of multiple databases and providing read-only endpoints. Options A (database mirroring) and D (log shipping) are not supported for Azure SQL Database. Option C (Always On availability groups) is a feature for SQL Server on Azure VMs, not for Azure SQL Database.
