To configure the VLAN trunking protocol to communicate VLAN information between two switches, what two requirements must be met?

1.Each end of the trunk link must be set to the IEEE 802.1e encapsulation.

2.The VTP management domain name of both switches must be set the same.

3.All ports on both the switches must be set as access ports.

4.One of the two switches must be configured as a VTP server.

5.A rollover cable is required to connect the two switches together.

6.A router must be used to forward VTP traffic between VLANs.

  • A.1, 2 and 4
  • B.3, 5 and 6
  • C.2 and 4
  • D.1 and 6

Answer: C

Correct answer: 2 and 4

Two conditions matter: the VTP domain name must match on both switches, since a switch ignores advertisements from any other domain, and at least one switch must be in server mode, because only a server can originate VLAN changes. The encapsulation need not be an IEEE one - ISL works equally - a trunk is required rather than access ports, an ordinary straight or crossover cable is used, and no router is involved in carrying VTP.
