CCNA Routing and Switching (legacy) — Question 110

How can you disable DTP on a switch port?

Answer options

• A. Configure the switch port as a trunk.
• B. Add an interface on the switch to a channel group.
• C. Change the operational mode to static access
• D. Change the administrative mode to access

Correct answer: D

Explanation

The correct answer is D because changing the administrative mode to access disables DTP by preventing the port from negotiating trunking. Options A and B do not disable DTP; configuring a port as a trunk or adding it to a channel group does not stop DTP negotiation. Option C, while changing the operational mode, does not directly affect DTP behavior.
