Question 10
A staff member can plug unknown USB devices into a sensitive workstation. Which testing or remediation action is most appropriate?
Explanation
Correct Answer
Enforce removable-media policy and endpoint device controls. This answer directly addresses the described constraint. Technical device restrictions supplement awareness training. Successful validation requires: An unapproved test drive is blocked and recorded.
Incorrect Answers
It would address a customer has stale machine account certificates with expired owners. The relevant reason in that case is: Key and certificate hygiene prevents service interruption and untrusted identity reuse. Here the required success condition is an unapproved test drive is blocked and recorded. The appropriate action is: Enforce removable-media policy and endpoint device controls.
That approach concerns a different situation: a production app stores an API key in a publicly readable deployment manifest. Secret revocation is necessary after disclosure; merely hiding a file is insufficient. The required result is that an unapproved test drive is blocked and recorded. The appropriate action is: Enforce removable-media policy and endpoint device controls.
That relates to a different issue: Physical testing shows unauthorized visitors can follow staff into a secure data center. Anti-tailgating controls reduce unauthorized physical entry. That is not a direct remedy for the requested outcome: An unapproved test drive is blocked and recorded. The appropriate action is: Enforce removable-media policy and endpoint device controls.
