Question 36
Domain 4: Design Cost-Optimized ArchitecturesDuring a database migration with AWS DMS, which task type should be used to perform an initial data load followed by ongoing replication?
Correct answer: C
Explanation
AWS DMS uses "Full Load + CDC" when you need to copy existing data first and then keep changes synchronized. "Full Load" migrates the initial dataset, and "CDC" (change data capture) continues replicating inserts, updates, and deletes after the load.
Why each option is right or wrong
A. Full Load only
B. CDC (Change Data Capture) only
C. Full Load + CDC
AWS Database Migration Service defines the migration task type that first copies the existing source tables and then continues capturing ongoing changes as a combined mode: full load plus change data capture (CDC). In practice, this is the only task type that covers both phases in one run, so it is the correct choice when the target must be seeded with the current dataset and then kept current with subsequent inserts, updates, and deletes.
D. Multiple Full Load tasks
