The Company switches have all been upgraded to use VTP version 2. What are two benefits
provided in VTP Version 2 that are not available in VTP Version 1? (Select two)

A.
VTP version 2 supports Token Ring VLANs

B.
VTP version 2 allows VLAN consistency checks

C.
VTP version 2 allows active redundant links when used with spanning tree

D.
VTP version 2 reduces the amount of configuration necessary

E.
VTP version 2 saves VLAN configuration memory

Explanation:
Understanding VTP Version 2
If you use VTP in your network, you must decide whether to use VTP version 1 or version 2.
Note: If you are using VTP in a Token Ring environment, you must use version 2.
VTP version 2 supports the following features not supported in version 1:
• Token Ring support—VTP version 2 supports Token Ring LAN switching and VLANs
(Token Ring Bridge Relay Function [TrBRF] and Token Ring Concentrator Relay Function
[TrCRF]).
• Unrecognized Type-Length-Value (TLV) Support—A VTP server or client propagates
configuration changes to its other trunks, even for TLVs it is not able to parse. The
unrecognized TLV is saved in NVRAM.
• Version-Dependent Transparent Mode—In VTP version 1, a VTP transparent network
device inspects VTP messages for the domain name and version, and forwards a message
only if the version and domain name match. Because only one domain is supported in the
supervisor engine software, VTP version 2 forwards VTP messages in transparent mode
without checking the version.
• Consistency Checks—In VTP version 2, VLAN consistency checks (such as VLAN
names and values) are performed only when you enter new information through the CLI or
SNMP. Consistency checks are not performed when new information is obtained from a VTP
message, or when information is read from NVRAM. If the digest on a received VTP
message is correct, its information is accepted without consistency checks.
