Over a cutover weekend, a county will replicate Microsoft SQL Server on premises to Amazon RDS for SQL Server with minimal downtime. Which service supports that migration pattern?
Select an answer to reveal the explanation.
Short Explanation
Same-engine moves still need a careful handoff—DMS can keep replicating so the cutover weekend is a flip, not a long outage. Polly turns text into speech, WAF filters web requests, and WorkSpaces is a virtual desktop—none haul SQL Server databases.
Full Explanation
Over a cutover weekend, when a county will replicate Microsoft SQL Server on premises to Amazon RDS for SQL Server with minimal downtime, AWS Database Migration Service (AWS DMS) supports that migration pattern. DMS handles database migration and replication, including homogeneous SQL Server paths, so changes can continue replicating until the weekend cutover flip with reduced downtime compared with offline-only copy approaches.
Amazon Polly synthesizes speech and does not stream database transaction logs for replication. AWS WAF filters HTTP requests and is not a continuous relational replication tunnel. Amazon WorkSpaces provides managed desktops; it is not a database cutover replication engine.
Exam caveat: Minimal-downtime DB migration/replication → DMS, whether homogeneous (SQL Server to RDS SQL Server) or heterogeneous. SCT is more about schema conversion between different engines; still know DMS as the data mover/replicator.
Operational check: size a DMS replication instance, create source/target endpoints, start full load plus CDC, validate row counts and critical stored procedures on RDS, rehearse application connection string cutover, and keep a rollback snapshot plan if Monday morning county systems misbehave.
