CCNA: Cisco Certified Network Associate — Question 364

A network engineer is asked to configure VLANS 2, 3, and 4 for a new implementation. Some ports must be assigned to the new VLANS with unused ports remaining. Which action should be taken for the unused ports?

Answer options

• A. configure in a nondefault native VLAN
• B. configure ports in the native VLAN
• C. configure ports in a black hole VLAN
• D. configure ports as access ports

Correct answer: C

Explanation

The correct answer is C because a black hole VLAN is used to prevent unused ports from being active and ensures that they do not receive any traffic. Options A and B do not address the need to disable unused ports, while option D merely designates ports as access without preventing traffic.
