What does VTP do, and what does the abbreviation stand for?
VLAN Trunking Protocol is a protocol used to transmit configuration information about
VLANs between interconnected switches. VTP helps prevent misconfiguration, eases
administration of the switches, and also reduces broadcast overhead by the use of VTP
pruning.

Name the three VTP modes. Which of these does not allow VLANs to be added or
modified?
Server and client modes are used to actively participate in VTP; transparent mode is used
to simply stay out of the way of servers and clients while not participating in VTP.
Switches in client mode cannot change or add VLANs.

What Catalyst 1900 switch command configures ISL trunking on fastethernet port 26 so
that as long as the switch port on the other end of the trunk is not disabled (off) or
configured to not negotiate to become a trunk, the trunk will definitely be placed in
trunking mode?
The trunk desirable interface subcommand tells this switch to be in trunking mode (in
other words, to use ISL) as long as the switch in the other end of the trunk is configured
for on, autonegotiate, or desirable. If the other switch has configured the trunk as off or
nonegotiate, trunking will not be enabled.
45
What type of VTP mode allows a switch to create VTP advertisements?
