At this point in a typical Config workflow, you would find the 251-MED-no-iam-users-except-whitelist Config Rule and trigger re-evaluation of the rule to confirm that your whitelisting had the desired effect (i.e. making the IAM user compliant for that rule). However, the Config API has a very, very threshold for the number of times that you can invoke revaluations. Therefore, the exercise leading leader will trigger re-evaluation just a few times during this hands-on session.

If you wanted to force Config to evaluate a Rule within your own AWS account, you would use the Re-evaluate action, as shown below.
