Answers
E.

The S3 object's ACL does not include READ_ACP access for the All Users group.

Suggested answer: A, B

Explanation:

Several factors can affect the availability of an S3 object through a presigned URL:

Expiration of Presigned URL: A presigned URL is valid only until its specified expiration time. Once expired, it becomes inaccessible.

Invalid Access Key: If the access key of the SysOps administrator who generated the presigned URL is revoked or rotated, the URL will no longer be valid.

Other options like enabling Block Public Access or changing the object ACL to All Users are not necessary for presigned URLs, as these URLs temporarily grant access regardless of public bucket settings.
