A user has granted read/write permission of his S3 bucket using ACL.Which of the below mentioned options is a valid ID to grant permission to other AWS accounts (grantee.using ACL?
IAM User ID
S3 Secure ID
Access ID
Canonical user ID
Explanations:
IAM User ID is not a valid identifier for granting permissions in S3 ACLs. IAM User IDs are used for identifying IAM users within AWS, but not for S3 ACLs.
S3 Secure ID is not a recognized term in AWS documentation for granting permissions. It may cause confusion, but it’s not valid for ACLs.
Access ID is not a valid identifier for granting permissions. Access keys (Access ID and Secret Access Key) are used for API requests, not ACLs.
Canonical user ID is the correct option. It is a unique identifier assigned to each AWS account, which can be used in S3 ACLs to grant permissions.
As far as I can tell, the answer is:
Canonical user ID
