Switch R1 is configured to use the VLAN Trunking Protocol (VTP). What does R1 advertise
in its VTP domain?
A.
The VLAN ID of all known VLANs, the management domain name, and the total
number of trunk links on the switch.
B.
The VLAN ID of all known VLANs, a 1 -bit canonical format (CF1 Indicator), and the
switch configuration revision number.
C.
The management domain name, the switch configuration revision number, the known
VLANs, and their specific parameters.
D.
A 2-byte TPID with a fixed value of 0x8100 for the management domain number, the
switch configuration revision number, the known VLANs, and their specific parameters.
E.
None of the other alternatives apply.
Explanation:
“Each switch participating in VTP advertises VLAN information, revision numbers, and VLAN
parameters on its trunk ports to notify other switches in the management domain. VTP
advertisements are sent as multicast frames. The switch intercepts frames sent to the VTP
multicast address and processes them with its supervisory processor VTP frames are
forwarded out trunk links as a special case.
The following global configuration information is distributed in VTP advertisements:
VLAN IDs (ISL and 802.1Q)
Emulated LAN names (for ATM LANE)
802.10 SAID values (FDDI)
VTP domain name
VTP configuration revision number
VLAN configuration, including maximum transmission unit (MTU) size for each VLAN
Frame format

Incorrect Answers:
A: The total number of trunk links is not advertised.
B: A CFI is not advertised.
D: The TPID is not advertised. The value of 0x8100 is used to identify an 802.1Q trunking
tag.
