Question

Quizplus · Accepted Answer

The VLAN Trunk Protocol (VTP) shares VLAN database information amongst switches that participate in the VTP domain. This allows for consistency in VLAN configuration across multiple switches.

Answer choices A, C, and D are incorrect because: 
A) It is the Port Aggregation Protocol (PAgP) or Link Aggregation Control Protocol (LACP) that is used for establishing a trunk between switches. 
C) Cisco's proprietary Dynamic Trunking Protocol (DTP) defines how the trunking negotiation occurs between switches.
