AWS - Identity and Access Management

Identify the error in this IAM policy statement:

{"Effect": "Allow", "Action": "s3:ListBucket", "Resource": "arn:aws:s3:::mybucket/*"}

AMissing 'Version' key at the policy root

B"Action" should be an array, not a string

CThe "Effect" value should be lowercase

DThe resource ARN is incorrect for ListBucket action

Step-by-Step Solution

Solution:

Step 1: Check the resource ARN for ListBucket
s3:ListBucket requires the bucket ARN "arn:aws:s3:::mybucket" WITHOUT /*. The /* is incorrect here as it specifies objects, not the bucket.
Step 2: Rule out other options
Missing 'Version' is ok for a statement snippet, "Action" string is valid, "Effect": "Allow" is correctly capitalized.
Final Answer:
Resource ARN incorrect for ListBucket (includes /*) -> Option D
Quick Check:
ListBucket Resource = arn:aws:s3:::bucket (no /*) [OK]

Quick Trick: s3:ListBucket requires bucket ARN without trailing /* [OK]
