A. Each end of the trunk line must be set to IEEE 802.1 E encapsulation.
B. The VTP management domain name of both switches must be set the same.
C. All ports on both the switches must be set as access ports.
D. One of the two switches must be configured as a VTP server.
E. A rollover cable is required to connect the two switches together.
F. A router must be used to forward VTP traffic between VLANs.
Answer: B,D
Explanation:
VLAN Trunking Protocol (VTP) is a Cisco proprietary Layer 2 messaging protocol that manages
the addition, deletion, and renaming of VLANs on a network-wide basis. Virtual Local Area
Network (VLAN) Trunk Protocol (VTP) reduces administration in a switched network. When you
configure a new VLAN on one VTP server, the VLAN is distributed through all switches in the
domain. This reduces the need to configure the same VLAN everywhere. To do this VTP carries
VLAN information to all the switches in a VTP domain. VTP advertisements can be sent over ISL,
802.1q, IEEE 802.10 and LANE trunks. VTP traffic is sent over the management VLAN (VLAN1),
so all VLAN trunks must be configured to pass VLAN1. VTP is available on most of the Cisco
Catalyst Family products.
VTP operates in one of three modes:
Server - In this VTP mode you can create, remove, and modify VLANs. You can also set other
configuration options like the VTP version and also turn on/off VTP pruning for the entire VTP
domain. VTP servers advertise their VLAN configuration to other switches in the same VTP
domain and synchronize their VLAN configuration with other switches based on messages
received over trunk links. VTP server is the default mode. The VLANs information are stored on
NVRAM and they are not lost after a reboot.
Client - VTP clients behave the same way as VTP servers, but you cannot create, change, or
delete VLANs on the local device. In VTP client mode, VLAN configurations are not saved in
NVRAM.
