Correct answer & explanation
✓
AWS Database Migration Service (DMS) with ongoing replication
AWS Database Migration Service (DMS) with ongoing replication can keep source and target databases in sync, allowing for minimal downtime during migration. Option A is wrong because AWS Direct Connect provides a dedicated network connection, not a replication service. Option C is wrong because Amazon S3 Transfer Acceleration is for faster uploads to S3, not for database replication. Option D is wrong because AWS Snowball Edge is an offline data transfer device, not a continuous replication tool.
