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.
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:1. VLAN IDs (ISL and 802.1Q)
2. Emulated LAN names (for ATM LANE)
3. 802.10 SAID values (FDDI)
4. VTP domain name
5. VTP configuration revision number
6. VLAN configuration, including maximum transmission unit (MTU) size for each VLAN

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.
