Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

✗
Taking a final full-disk backup to a public S3 bucket
Why it's wrong here
This creates a major data leak risk.
✓
Deleting associated snapshots and backups
Why this is correct
Snapshots can contain sensitive data that persists after the VM is deleted.
✗
Updating the local hardware inventory
Why it's wrong here
In a cloud environment, you do not manage local hardware inventory.
✓
Terminating the compute instance
Why this is correct
Actual termination is the final step in the lifecycle.
✓
Removing identity and access management (IAM) permissions
Why this is correct
Removing permissions prevents the decommissioned account or resource from being misused.
