AIncorrect
Versioning
Versioning is a feature that keeps multiple versions of an object to protect against accidental deletion and overwrite.
It is not a feature that moves between tiers or deletes based on elapsed time, so it is incorrect.
You want to automatically manage logs stored in S3 with the rule 'move to an infrequent-access tier 30 days after creation, automatically move to Glacier after 1 year, and delete after 7 years'. Which S3 feature should you use?

Select an answer
CorrectB
Explanation
Choosing the S3 feature that automates tier transition and deletion based on age.
- 1「move to an infrequent-access tier 30 days after creation」Transition based on age
- 2「automatically move to Glacier after 1 year」Automation of staged tier transitions
- 3「delete after 7 years」Automatic deletion by expiration = lifecycle
BCorrect
Lifecycle policy
Correct. An S3 lifecycle policy defines rules to automatically transition objects to another storage class based on age or to delete them after a period (expiration). It automates staged cost optimization and retention management for logs.
CIncorrect
Static website hosting
Static website hosting is a feature that serves HTML and other files from an S3 bucket over the web.
It is not a feature that moves tiers or deletes based on age, so it is incorrect.
DIncorrect
Cross-Region Replication
Cross-Region Replication is a feature that replicates objects to another Region.
It is not tier transition or deletion based on age, so it is incorrect.
Key Takeaway
'Tier transition and deletion by age' points to the S3 lifecycle policy. Versioning (version management), replication (copying), and static hosting (delivery) have different purposes.
