Refer to the exhibit. What will be the result of issuing the following commands? Switch1(config)#
interface fastethernet 0/5Switch1(config-if)# switchport mode accessSwitch1(config-if)# switchport
access vlan 30
A.
The VLAN will be added to the database and VLAN 30 will be passed on as a VLAN to add to
the Switch2 VLAN database.
B.
The VLAN will not be added to the database, nor will the VLAN 30 information be passed on as
a VLAN to the Switch2 VLAN database.
C.
The VLAN will be added to the database, but the VLAN information will not be passed on to the
Switch2 VLAN database.
D.
The VLAN will not be added to the database, but the VLAN 30 information will be passed on as
a VLAN to the Switch2 VLAN database.
Explanation:
The three VTP modes are described below:
Server: This is the default for all Catalyst switches. You need at least one server in your VTP
domain to propagate VLAN information throughout the domain. The switch must be in server
mode to be able to create, add, or delete VLANs in a VTP domain. You must also change VTP
information in server mode, and any change you make to a switch in server mode will be
advertised to the entire VTP domain.
Client: In client mode, switches receive information from VTP servers; they also send and receive
updates, but they can’t make any changes. Plus, none of the ports on a client switch can be added
to a new VLAN before the VTP server notifies the client switch of the new VLAN. Here’s a hint: if
you want a switch to become a server, first make it a client so that it receives all the correct VLAN
information, then change it to a server-much easier!
Transparent: Switches in transparent mode don’t participate in the VTP domain, but they’ll still
forward VTP advertisements through any configured trunk links. These switches can’t add and
delete VLANs because they keep their own database-one they do not share with other switches.
Transparent mode is really only considered locally significant.
In our example, the switch is configured for transparent mode. In transparent mode the local
VLAN information can be created but that VLAN information will not be advertised to the other
switch.
