Modules 1 - 4: Switching Concepts, VLANs, and
InterVLAN Routing Exam with complete solution
Which tasks can be accomplished by using the command history feature?
(Choose two.)
Set the command history buffer size.
Recall previously entered commands.
What is the first action in the boot sequence when a switch is powered on?
load a power-on self-test program
What must an administrator have in order to reset a lost password on a router?
physical access to the router
When configuring a switch for SSH access, what other command that is
associated with the login local command is required to be entered on the switch?
username username secret secret
Which command displays information about the auto-MDIX setting for a specific
interface?
show controllers
If one end of an Ethernet connection is configured for full duplex and the other
end of the connection is configured for half duplex, where would late collisions
be observed?
on the half-duplex end of the connection
Which command is used to set the BOOT environment variable that defines
where to find the IOS image file on a switch?
boot system
What does a switch use to locate and load the IOS image?
BOOT environment variable
Which protocol adds security to remote connections?
SSH
What is a characteristic of an IPv4 loopback interface on a Cisco IOS router?
It is a logical interface internal to the router.
What is the minimum Ethernet frame size that will not be discarded by the
receiver as a runt frame?
64 bytes
After which step of the switch bootup sequence is the boot loader executed?
after POST execution
Which impact does adding a Layer 2 switch have on a network?
an increase in the size of the broadcast domain
Which characteristic describes cut-through switching?
Frames are forwarded without any error checking.
What is the significant difference between a hub and a Layer 2 LAN switch?
A hub extends a collision domain, and a switch divides collision domains.
Which statement is correct about Ethernet switch frame forwarding decisions?
Frame forwarding decisions are based on MAC address and port mappings in the
CAM table.
How do switch buffers affect network performance?
, They store frames received, thus preventing premature frame discarding when
network congestion occurs.
Which switch characteristic helps keep traffic local and alleviates network
congestion?
high port density
Which switch component reduces the amount of packet handling time inside the
switch?
ASIC
Refer to the exhibit. A switch receives a Layer 2 frame that contains a source
MAC address of 000b.a023.c501 and a destination MAC address of
0050.0fae.75aa. Place the switch steps in the order they occur. (Not all options are
used.)
What information is added to the switch table from incoming frames?
source MAC address and incoming port number
Which switching method ensures that the incoming frame is error-free before
forwarding?
store-and-forward
Refer to the exhibit. How many broadcast domains are displayed?
8
Under which two occasions should an administrator disable DTP while managing
a local area network? (Choose two.)
when connecting a Cisco switch to a non-Cisco switch
on links that should not be trunking
Which two characteristics describe the native VLAN? (Choose two.)
The native VLAN traffic will be untagged across the trunk link.
The native VLAN provides a common identifier to both ends of a trunk.
On a switch that is configured with multiple VLANs, which command will remove
only VLAN 100 from the switch?
Switch(config)# no vlan 100
Refer to the exhibit. A network administrator is reviewing port and VLAN
assignments on switch S2 and notices that interfaces Gi0/1 and Gi0/2 are not
included in the output. Why would the interfaces be missing from the output?
They are configured as trunk interfaces.
