Chapter 5 test

Which type of inter-VLAN communication
design requires the configuration of multiple
PHYSICAL interfaces (wasting cables and ports
on both switches and routers)

Legacy Inter-VLAN routing

Which type of inter-VLAN communication
design requires the configuration of multiple
sub interfaces, but only one physical interface?

Router on a Stick


In this diagram, the SWITCH
does the routing for the hosts
that connect to VLAN 5. If a
computer connects to a Web
Server from the Internet, will a
VLAN number be added to the
frame?
No, VLAN id’s are only added
when the VLAN is being routed
by a router, this is being done by
this layer three switch


A disadvantage of Router on the stick is that it
doesn’t scale well. How many VLANs did the
curriculum say you could have on Router-on-astick VLAN routing?
50


When using multiple VLANs on a multilayer
switch, how is traffic routed?
Using internal VLAN interfaces on the switch
(they are VIRTUAL not physical interfaces)


If you are using LEGACY inter-vlan equipment
and you need to have two vlans, how many
physical interfaces are needed on the router to
enable the communication between the two
vlans?
At least two LAN interfaces should be used


If you configure a router with Sub interfaces for
vlans, and attach that router to a switch’s
Gigabit interface, what command must you
enter on the switch in order to allow for inter
VLAN routing?
Switchport mode trunk


True or false: Administrative distance refers to
the TRUSTIWORTHINESS of a particular
route. The lower the number, the more
trustiworthy the route.
That is CORRECT



R3efer to the exhibit. PCs on different VLANs
cannot communicate. What are two errors
Gig1/1 is in the default VLAN
Gig1/1 is configured



Users complain that PC2 cannot communicate with
PC1. Based on the output, what is the possible
cause of the problem?
The encapsulation dot1Q 5 command contains the
wrong VLAN
Note: The subinterfaces do not need a no
shutdown command and the fact that it is using
subinterface 0/0.5 is okay, but it is not okay that
the dot1Q 5 is there, it should be dot1Q 10


When creating a ROUTED PORT for a single
network on a MULTILAYER SWITCH, (layer 2
and 3), what command must be entered on the
switches interface?
To create a routed port for a single network


What is an advantage of using a multilayer
switch for inter-VLAN routing?
The are much faster because all the switching
stays in the switch


What is a disadvantage of using multilayer
swtiches for inter-VLAN routing??
They are more expensive than router-on-a-stick


When creating inter-VLAN routing on a
multilayer switch, what is a virtual-routed
VLAN interface called?
SVI


What command is used to display the list of
VLANs that exist on the switch?
Show VLANs
