Question 500
A switch port is configured to accept tags from an untrusted endpoint. Which result shows the selected action was suitable and effective?
Explanation
Correct Answer
A lab segmentation test shows untrusted frames cannot reach protected VLANs. This answer directly addresses the described constraint. Incorrect trunk or native VLAN settings can break intended network segregation. Successful validation requires: A lab segmentation test shows untrusted frames cannot reach protected VLANs.
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 lab segmentation test shows untrusted frames cannot reach protected VLANs. The relevant evidence is: A lab segmentation test shows untrusted frames cannot reach protected VLANs.
It would address a tester sees port 445 on an authorized server but has no credentials to enumerate its shares. The relevant reason in that case is: Service availability is not the same as permission to enumerate protected resources. Here the required success condition is a lab segmentation test shows untrusted frames cannot reach protected VLANs. The relevant evidence is: A lab segmentation test shows untrusted frames cannot reach protected VLANs.
This result applies to a different case: A tester is considering a public Metasploit module that attempts service disruption. An available exploit module is not inherently appropriate for production testing. It does not establish the present requirement, where a lab segmentation test shows untrusted frames cannot reach protected VLANs. The relevant evidence is: A lab segmentation test shows untrusted frames cannot reach protected VLANs.
