AWS Certified SysOps Administrator SOA-C01 – Question220 - AWS Certified SysOps Administrator SOA-C01

A root account owner has given full access of his S3 bucket to one of the IAM users using the bucket ACL. When the IAM user logs in to the S3 console, which actions can he perform?

A. He can just view the content of the bucket
B. He can do all the operations on the bucket
C. It is not possible to give access to an IAM user using ACL
D. The IAM user can perform all operations on the bucket using only API/SDK

Correct Answer: C

Explanation:

Explanation: Each AWS S3 bucket and object has an ACL (Access Control List) associated with it. An ACL is a list of grants identifying the grantee and the permission granted. The user can use ACLs to grant basic read/write permissions to other AWS accounts. ACLs use an Amazon S3–specific XML schema. The user cannot grant permissions to other users (IAM users) in his account.
