PAS-C01 Migration Practice Question

Exhibit

Refer to the exhibit. The following is an IAM policy attached to an EC2 instance role:

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Action": [
                "s3:GetObject",
                "s3:PutObject",
                "s3:DeleteObject"
            ],
            "Resource": "arn:aws:s3:::sap-migration-bucket/*"
        },
        {
            "Effect": "Allow",
            "Action": [
                "dms:CreateReplicationTask",
                "dms:StartReplicationTask"
            ],
            "Resource": "*"
        }
    ]
}

An SAP administrator is trying to run an AWS DMS replication task from an EC2 instance that has this IAM role. The task fails with an access denied error. 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 include permissions for dms:DescribeReplicationTasks.

The IAM policy attached to the EC2 instance role does not include permissions for the dms:DescribeReplicationTasks action. When the DMS replication task is started, the DMS service needs to describe the task status and list replication tasks, which requires this action. Without it, the API call fails with an access denied error. Although the policy includes dms:CreateReplicationTask and dms:StartReplicationTask, the absence of dms:DescribeReplicationTasks causes the failure. Option D correctly identifies this missing permission.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • The EC2 instance role is not attached to the instance.

    Why it's wrong here

    The administrator is trying to run the task, so the role is likely attached.

  • The S3 bucket name is incorrect.

    Why it's wrong here

    The S3 action is allowed on the correct bucket.

  • The S3 actions require additional permissions for the bucket.

    Why it's wrong here

    S3 actions are already allowed on the bucket.

  • The policy does not include permissions for dms:DescribeReplicationTasks.

    Why this is correct

    To start a task, DMS may need to describe replication tasks first.
