AWS Certified SysOps Administrator – Associate (legacy) — Question 441

In Amazon S3, what is the document that defines who can access a particular bucket or object called?

Answer options

• A. Access Control Record
• B. Access Control Service
• C. Access Control List
• D. Access Control Server

Correct answer: C

Explanation

An Access Control List (ACL) is a subresource document in Amazon S3 that defines which AWS accounts or predefined groups are granted access to a bucket or an individual object. While modern AWS environments often use IAM policies or bucket policies, ACLs remain a legacy method for managing resource-level permissions. The other options are incorrect as they do not represent actual Amazon S3 access management mechanisms.
