Refer to the exhibit. A data engineer has an IAM policy attached to an IAM role used by an AWS Glue job. The Glue job reads from S3 bucket 'example-bucket' and writes to an S3 bucket 'output-bucket'. The job fails with an 'Access Denied' error when writing to 'output-bucket'. What is the MOST likely cause?

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

✓

The policy does not allow s3:PutObject on 'output-bucket'.

The policy only allows s3:PutObject on 'example-bucket/*', not on 'output-bucket/*'. The job needs permission on the output bucket. Option A is incorrect because s3:PutObject is allowed on example-bucket, but not on output-bucket. Option C is incorrect because there is no condition that restricts PutObject to example-bucket. Option D is incorrect because the policy allows s3:GetObject on example-bucket, which is for reading.
