DBS-C01 Deployment and Migration Practice Question
Which TWO AWS services can be used to migrate a MongoDB database to Amazon DocumentDB? (Choose 2.)

Correct answer & explanation
✓
AWS Database Migration Service (AWS DMS)
AWS Database Migration Service (AWS DMS) supports MongoDB as a source and Amazon DocumentDB as a target, enabling continuous replication with change data capture (CDC) for minimal downtime. MongoDB native tools (mongodump and mongorestore) are also valid for offline, one-time migrations by exporting the database as BSON files and importing them directly into DocumentDB.
