Question:
What is true about DTP? (Choose Three.)

  • Layer 2 protocol
  • Layer 3 protocol
  • Proprietary protocol
  • enabled by default
  • disabled by default

Explanation: The Dynamic Trunking Protocol (DTP) is a proprietary networking protocol developed by Cisco Systems for the purpose of negotiating trunking on a link between two VLAN-aware switches, and for negotiating the type of trunking encapsulation to be used. It is a Layer 2 protocol and it is enabled by default on Cisco switches (so the interfaces of your switches will be in “dynamic auto” or “dynamic desirable” mode). If you want to turn it off, use the “switchport nonegotiate” under interface mode.
