How should the architect implement database high availability in SQL Server?

The correct answer is A. By using SQL Server Mirroring. SQL Server Mirroring is an effective high-availability solution that maintains a hot standby database, ensuring rapid failover and minimal data loss for a single database.

Why each option

SQL Server Mirroring is an effective high-availability solution that maintains a hot standby database, ensuring rapid failover and minimal data loss for a single database.

ABy using SQL Server MirroringCorrect

SQL Server Mirroring provides a high-availability solution for a single user database, maintaining a synchronized copy (mirror) that can be quickly brought online as the principal database in case of a failure, offering automatic failover and transaction-level redundancy.

BBy using SQL Server replication

SQL Server replication is primarily a data distribution technology used for copying and synchronizing data between databases, not a real-time high-availability solution for immediate failover.

CBy implementing SQL Server log shipping

SQL Server log shipping involves periodically backing up and restoring transaction logs from a primary to one or more secondary databases, providing disaster recovery but not automatic, near-instantaneous failover for high availability.

DBy using hypervisor high availability

Hypervisor high availability (e.g., VMware HA, Hyper-V Failover Clustering) ensures the availability of the virtual machine running SQL Server, but it does not provide database-level high availability or protect against database corruption or logical failures within the SQL Server instance itself.
