Question #1698
A company needs to archive its database backups on Amazon S3. The backups must be retained for 45 days and automatically deleted afterward. Which combination of steps meets these requirements? (Choose three.)
Create an S3 bucket with S3 Object Lock enabled.
Enable S3 versioning on the bucket.
Configure a default retention period of 45 days for the objects.
Configure an S3 Lifecycle policy to transition objects to Glacier after 45 days.
Configure an S3 Lifecycle policy to expire objects after 45 days.
Configure the archiving tool to tag objects with a 45-day retention tag.
Explanation
To meet the requirements:
1. A (S3 Object Lock) ensures backups are immutable during retention.
2. C (Default retention period) sets the 45-day lock duration.
3. E (Lifecycle expiration) deletes objects post-retention.
Why not others?
- B (Versioning) is unnecessary as backups don't require version history.
- D (Glacier transition) doesn't delete objects.
- F (Tagging) adds complexity; default retention (C) is simpler.
Key Points: Use S3 Object Lock with retention periods and Lifecycle policies for time-bound deletion.
Answer
The correct answer is: ACE
