Which two benefits can be obtained by using VTP in a switching environment? (Choose two.)
A.
Allowing frames from multiple VLANs to use a single interface.
B.
Allowing switches to read frame tags.
C.
Maintaining VLAN consistency across a switched network.
D.
Allowing VLAN information to be automatically propagated throughout the switching environment.
E.
It allows ports to be assigned to VLANs automatically.
Explanation:
VTP minimizes the possible configuration inconsistencies that arise when changes are made. These inconsistencies can result in security violations, because VLANs can crossconnect when duplicate names are used. They also could become internally disconnected when they are mapped from one LAN type to another, for example, Ethernet to ATM LANE ELANs or FDDI 802.10 VLANs. VTP provides a mapping scheme that enables seamless trunking within a network employing mixed-media technologies.
VTP provides the following benefits:
* VLAN configuration consistency across the network
* Mapping scheme that allows a VLAN to be trunked over mixed media
* Accurate tracking and monitoring of VLANs
* Dynamic reporting of added VLANs across the network
* Plug-and-play configuration when adding new VLANs
