To configure the VLAN trunking protocol to communicate VLAN information between two switches, what two requirements must be met? (Choose two.)
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 seiver.
E.
A rollover cable is required to connect the two switches together.
F.
A router must be used to forward VTP traffic between VLANs.
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 seiver, 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, 802.1 q, 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:
Seiver – 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 seivers 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 seiver 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 seivers, but you cannot create, change, or delete VLANs on the local device. In VTP client mode, VLAN configurations are not saved in NVRAM.
