Question 20
A management-plane interface is reachable from the guest network. What is the MOST appropriate analyst action based on the evidence?
Explanation
Correct Answer
Guest access to device control planes increases privilege-escalation opportunity. Isolate network-device management plane.
Incorrect Answers
Security logs can themselves contain sensitive infrastructure intelligence. It could help stop unauthorized DNS-log forwarding, but it would not isolate network-device management plane.
Unexpected attachment may represent rogue access or maintenance drift. That is relevant to network device and service context, not to isolate network-device management plane.
Terminating TLS at the edge does not secure exposed backend traffic. It would remediate unencrypted backend service hop, but it would not isolate network-device management plane.
