    The answer to the question is bit confusing since large files with kms encryption fails However, when they tried to upload a smaller file with the KMS key, the upload succeeds.

    1. QUESTION

    A media company runs a Python script that uses the AWS CLI command aws s3 cp to upload a large file to an Amazon S3 bucket, which includes an AWS KMS key. An Access Denied error always shows up whenever their developers upload a file with a size of 10 GB or more. However, when they tried to upload a smaller file with the KMS key, the upload succeeds.

    ———

    Which of the following are potential reasons why this issue is happening? (Select TWO.)

    these are the suggested answers as par the course, however I think if it was a real permission issue it should fail for both larger/smaller files

    The AWS CLI S3 commands perform a multipart upload when the file is large.

    The IAM policy of the developer does not include the kms:Decrypt permission.
