CCNA3 Exploration Chapter 3. Study questions.
3.1
Why is it generally a good idea to split up a large network into
smaller
networks?What is the advantage of implementing subnets as VLANs
rather than usingrouters to separate subnets?How many VLANs can
there be on a Catalyst 2600 series switch?Which VLANs exist by
default on a Catalyst 2600 switch, and which of theseare intended
for Ethernet networks?If you create a normal range VLAN, where will
the information about it bestored?A new Catalyst switch has not yet
been configured. Are the Ethernet portsassociated with any VLAN? If
so, which one?Should you configure the switch IP address on VLAN
1?What name is given to the type of VLAN that carries normal user
traffic suchas files, downloads and e-mails?Which type of VLAN
needs special configuration so that its traffic has priorityover
other traffic?What are the two methods of assigning an end device
to a VLAN, and whichmethod is more common? (Assume that voice
traffic is not required.)A PC attached to a switch sends out a
broadcast ARP request. Which deviceswill receive the ARP
request?Which devices allow inter-VLAN communication?What is a VLAN
trunk?
What is frame tagging?Which protocol is now most commonly used
for frame tagging, and whichother protocol may still be in use?What
is the purpose of the EtherType field in a frame, which is set to
thehexadecimal value of 0x8100?What does a switch port on a trunk
link do if it receives a frame without a tag?Why can native VLANs
and VLAN trunks give problems when Cisco devicesand non-Cisco
devices are mixed on a network?How can you configure the
fastethernet interface fa0/1 of switch SW1 to be atrunk port?How
can you configure the fastethernet interface fa0/2 of switch SW1 to
be a
port that handles traffic from one VLAN only?What is the purpose
of Dynamic Trunking Protocol?Two switches are connected. If both
ends of the link are ports in dynamic automode, will the link be a
trunk or not?Two switches are connected. If both ends of the link
are ports in dynamicdesirable mode, will the link be a trunk or
not?What is the currently approved method of creating a VLAN,
number 6, calledFinance, on switch SW1?Which other mode could be
used for creating a VLAN?Which command will let you see a list of
all existing VLANs and the ports thatare associated with each
one?
What information does the command show vlan summary give
you?Which command would show you whether or not VLAN 4 is up?

What is the effect of the commands:SW1(config)#int
fa0/12SW1(config-if)#no switchport access
vlanSW1(config-if)#endWhat is the effect of the commands:
SW1(config)#no vlan 7SW1(config)#exitWhat is the effect of the
command:SW1(config)#delete flash:vlan.datYou configure interface
Fa0/1 as follows:SW1(config-if)#switchport mode trunkWhich is the
native VLAN, and which VLANs can this interface handle?Which
additional commands would you give to make VLAN 90 the nativeVLAN
and to permit traffic belonging to VLANs 3, 4 and 5 only?Which
command would show you how interface Fa0/1 has been configuredfor
trunking?
You give the commands:SW1(config)#int fa0/1SW1(config-if)#no
switchport trunk allowed vlanSW1(config-if)#endWhich VLAN traffic
can now pass over the trunk link?How can you stop interface Fa0/1
from being a trunk link?A trunk link is not working correctly. What
should you check?
