Question 320
A lab network has a dual-homed server forwarding traffic between segmented networks. What observation would best confirm the intended security outcome?
Explanation
Correct Answer
A safe connectivity test confirms the unintended path is blocked. This answer directly addresses the described constraint. Unexpected forwarding can bypass security boundaries. Successful validation requires: A safe connectivity test confirms the unintended path is blocked.
Incorrect Answers
That approach concerns a different situation: a client wants to evaluate an old Telnet management interface without reading passwords. Telnet lacks built-in encrypted session protection. The required result is that a safe connectivity test confirms the unintended path is blocked. The relevant evidence is: A safe connectivity test confirms the unintended path is blocked.
That relates to a different issue: A lab server accepts SMB authentication relayed from another service without enforcing signing. Unsigned authentication flows can be replayed or relayed across trust boundaries. That is not a direct remedy for the requested outcome: A safe connectivity test confirms the unintended path is blocked. The relevant evidence is: A safe connectivity test confirms the unintended path is blocked.
It would address a tester is considering a public Metasploit module that attempts service disruption. The relevant reason in that case is: An available exploit module is not inherently appropriate for production testing. Here the required success condition is a safe connectivity test confirms the unintended path is blocked. The relevant evidence is: A safe connectivity test confirms the unintended path is blocked.
