Implementing and Operating Cisco Collaboration Core Technologies (CLCOR) — Question 411

Where does an administrator establish the trust boundary on a LAN?

Answer options

• A. access switch
• B. distribution switch
• C. voice VLAN
• D. core router

Correct answer: A

Explanation

The correct answer is A, the access switch, because it is the point where end devices connect to the network and where security policies are enforced. The distribution switch and core router do not directly manage end-user connections, and the voice VLAN is a specific type of VLAN rather than a boundary point.
