DBS-C01 Deployment and Migration Practice Question
Network Topology
Refer to the exhibit. A database specialist is taking a final snapshot of an RDS DB instance before deletion. The command returns the output shown. The snapshot is at 75% progress. What should the specialist do next?
⚠ Common exam trap
A common mix-up: candidates assume the snapshot continues independently after instance deletion (Option D), but AWS RDS enforces that the instance cannot be deleted until the final snapshot is fully available, preventing data loss.

Correct answer & explanation
✓
Wait for the snapshot status to become 'available' before deleting the instance.
An RDS DB instance cannot be deleted while a final snapshot is in progress; the snapshot must reach the 'available' status first. The AWS CLI output shows the snapshot at 75% progress, meaning the snapshot is still being created. Attempting to delete the instance before the snapshot completes will result in an error, as the deletion operation requires the snapshot to be fully available.

Use the describe-db-snapshots command with --db-snapshot-identifier to get more details.
