ICND2: Interconnecting Cisco Networking Devices Part 2 (legacy) — Question 46

Which statement about DTP is true?

Answer options

• A. It uses the native VLAN.
• B. It negotiates a trunk link after VTP has been configured.
• C. It uses desirable mode by default.
• D. It sends data on VLAN 1.

Correct answer: A

Explanation

The correct answer is A because DTP (Dynamic Trunking Protocol) indeed uses the native VLAN for its operations. Option B is incorrect as DTP negotiates trunk links independently of VTP configuration. Option C is false since DTP operates in auto mode by default, not desirable mode. Option D is misleading as DTP can operate on any VLAN, not just VLAN 1.
