A router has two serial interfaces and two
FastEthernet interfaces. It needs to connect to a wide area link to
the main office and to four VLANs in the local network. How can this
be accomplished in the most efficient manner?
Connect a trunked uplink from the
switch to a router FastEthernet interface and create logical
subinterfaces for each VLAN.
Use a hub to connect the four VLANS
with a FastEthernet interface on the router.
Two additional FastEthernet
interfaces are required to interconnect the VLANs.
Use serial to FastEthernet
transceivers to connect two of the VLANs to the router. Attach the
other two VLANs directly to the available FastEthernet ports.
Add a second router to handle the
inter-VLAN traffic.

The switches in the diagram are connected with trunks
within the same VTP management domain. Each switch is labeled with
its VTP mode. A new VLAN is added to Switch3. This VLAN does not
show up on the other switches. What is the reason for
this?
VLANs cannot be created on
transparent mode switches.
Server mode switches neither listen
to nor forward VTP messages from transparent mode switches.
VLANs created on transparent mode
switches are not included in VTP advertisements.
There are no ports assigned to the
new VLAN on the other switches.
Transparent mode switches do not
forward VTP advertisements.

Refer to the graphic. What are some advantages of
replacing the individual VLAN links between Switch1 and Switch2 with
a single trunk line? (Choose three.)
It would free 2 switch ports on
each switch.
It would free 3 switch ports on
each switch.
It would save 2 cabling runs.
It would save 3 cabling runs.
It would provide three times the
bandwidth of the individual links.
It would allow adding more VLANs
without requiring more cabling or switch
ports.

A switch is configured with the commands shown in the
diagram. Host1 is connected to port 0/4 with an IP address of
192.168.1.22/28. Host2 is connected to port 0/5 with an IP address
of 192.168.1.33/28. Host3 is connected to port 0/6 with an IP
address of 192.168.1.30/28. Select the statements that describe the
success of pinging from one host to another. (Choose
three.)
Host1 can ping Host2.
Host1 cannot ping Host2.
Host1 can ping Host3.
Host1 cannot ping Host3.
Host2 can ping Host3.
Host2 cannot ping
Host3.
5
A router is configured to connect to a trunked uplink
as shown in the graphic. A packet is received on the FastEthernet
0/1 physical interface from VLAN 10. The packet destination address
is 192.168.1.120. What will the router do with this
packet?
The router will forward the packet
out interface FastEthernet 0/1.1 tagged for VLAN 10.
The router will forward the packet
out interface FastEthernet 0/1.2 tagged for VLAN 60.
The router will forward the packet
out interface FastEthernet 0/1.3 tagged for VLAN 60.
The router will forward the packet
out interface FastEthernet 0/1.3 tagged for VLAN 120.
The router will not process the
packet since the source and destination are on the same
subnet.
The router will drop the packet
since no network that includes the source address is attached to the
router.
6
A switch in a VTP domain sends an advertisement
request. What will be the response?
A configuration status reply will
be issued from the closest client switch.
A three-way handshake will
establish a configuration session with the VTP server.
Summary and subset advertisements
will be sent by the VTP server.
The configuration version number
will be set to zero and all switches in the domain will issue
advertisements regarding the state of their
VLANs.
7

What should be done before moving a Catalyst switch to
a new VTP management domain? (Choose three.)
Verify that the new switch has a
lower configuration revision number than the other switches in the
domain.
Reset the VTP counters to allow the
switch to synchronize with the other switches in the domain.
Download the VTP database from the
VTP server in the new domain.
Configure the VTP server in the
domain to recognize the BID of the new switch.
Select the correct VTP mode and
version.
Configure the switch with the name
of the new management domain.
9

router interface for VLAN trunking? (Choose three.)
one subinterface per VLAN
one physical interface for each
subinterface

each subinterface

a management domain for each
subinterface
a compatible trunking protocol
encapsulation for each subinterface
10
By default, to which VLAN does a trunked link
belong?
the first VLAN defined

graphic, how many links would be required to carry the traffic for
all the VLANs between the switches?

links along the path between hosts A and B will a VLAN ID tag be
included with the frame?
C, E

the graphic? (Choose three.)
This design will not scale
easily.
This design exceeds the maximum
number of VLANs that can be attached to a switch.
