Which tasks can be accomplished by using the command history feature? (Choose two.)
View a list of commands entered in a previous session.
Recall previously entered commands.
Save command lines in a log file for future reference.
Set the command history buffer size.
Recall up to 15 command lines by default.
Which statement describes the system LED operation on Cisco Catalyst switches?
If the LED is amber, the system is receiving power but it is not functioning properly.
If the LED is blinking green, the system is operating normally.
If the LED is amber, the system is not powered on.
If the LED is blinking amber, the switch is performing POST.
What type of Ethernet cable would be used to connect one switch to another switch when neither switch supports the auto-MDIX feature?
coaxial
rollover
crossover
straight-through
What advantage does SSH offer over Telnet?
username and password authentication
encryption
connection-oriented services
more connection lines
What is the first action in the boot sequence when a switch is powered on?
low-level CPU initialization
load a power-on self-test program
load the default Cisco IOS software
load boot loader software
Which command will provide information about the status of all interfaces including the number of giants, runts, and collisions on the interface?
show ip interface brief
show running-config
show history
show interfaces
Which statement is true about broadcast and collision domains?
The size of the collision domain can be reduced by adding hubs to a network.
The more interfaces a router has the larger the resulting broadcast domain.
Adding a router to a network will increase the size of the collision domain.
Adding a switch to a network will increase the size of the broadcast domain.
What is one function of a Layer 2 switch?
forwards data based on logical addressing
determines which interface is used to forward a frame based on the destination MAC address
duplicates the electrical signal of each frame to every port
learns the port assigned to a host by examining the destination MAC address
What will a Cisco LAN switch do if it receives an incoming frame and the destination MAC address is not listed in the MAC address table?
Send the frame to the default gateway address.
Forward the frame out all ports except the port where the frame is received.
Drop the frame.
Use ARP to resolve the port that is related to the frame.
Which switch characteristic helps alleviate network congestion when a 10 Gbps port is forwarding data to a 1 Gbps port?
frame buffering
high port density
fast internal switching
fast port speed
Which switching method makes use of the FCS value?
store-and-forward
broadcast
cut-through
large frame buffer
Which information does a switch use to keep the MAC address table information current?
the source and destination MAC addresses and the incoming port
the source MAC address and the incoming port
the destination MAC address and the incoming port
the source and destination MAC addresses and the outgoing port
the source and destination MAC addresses and the outgoing port
What happens to a port that is associated with VLAN 10 when the administrator deletes VLAN 10 from the switch?
The port creates the VLAN again
The port becomes inactive
The port goes back to the default VLAN
The port automatically associates itself with the native VLAN
An administrator is investigating a failure on a trunk link between a Cisco switch and a switch from another vendor. After a few show commands, the administrator notices that the switches are not negotiating a trunk. What is a probable cause for this issue?
Both switches are in trunk mode
Switches from other vendors do not support DTP
Both switches are in nonegotiate mode
DTP frames are flooding the entire network
What is the purpose of the vlan.dat file on a switch?
It holds the operating system.
It holds the saved configuration.
It holds the VLAN database.
It holds the running configuration.
When a Cisco switch receives untagged frames on a 802.1Q trunk port, which VLAN ID is the traffic switched to by default?
management VLAN ID
native VLAN ID
data VLAN ID
unused VLAN ID
A network administrator is determining the best placement of VLAN trunk links. Which two types of point-to-point connections utilize VLAN trunking? (Choose two.)
between a switch and a network printer
between a switch and a server that has an 802.1Q NIC
between two switches that utilize multiple VLANs
between a switch and a client PC
between two switches that share a common VLAN
Which distinct type of VLAN is used by an administrator to access and configure a switch?
management VLAN
data VLAN
native VLAN
default VLAN
A PC is to access a web server on another network. Which inter-VLAN method will provide the highest bandwidth at Layer 3 and also provide a default gateway for the PC?
trunked interface between the router and the switch
multiple physical interfaces on the router, all connected to a Layer 2 switch
router on a stick
multilayer switch with routing enabled
A small college uses VLAN 10 for the classroom network and VLAN 20 for the office network. What is needed to enable communication between these two VLANs while using legacy inter-VLAN routing?
Two groups of switches are needed, each with ports that are configured for one VLAN.
A router with at least two LAN interfaces should be used.
A switch with a port that is configured as trunk is needed to connect to a router.
A router with one VLAN interface is needed to connect to the SVI on a switch.
What is a disadvantage of using multilayer switches for inter-VLAN routing?
Spanning tree must be disabled in order to implement routing on a multilayer switch.
Multilayer switches are limited to using trunk links for Layer 3 routing.
Multilayer switches have higher latency for Layer 3 routing.
Multilayer switches are more expensive than router-on-a-stick implementations.
What is a disadvantage of using router-on-a-stick inter-VLAN routing?
requires the use of multiple router interfaces configured to operate as access links
does not scale well beyond 50 VLANs
does not support VLAN-tagged packets
requires the use of more physical interfaces than legacy inter-VLAN routing
What is the meaning of the number 10 in the encapsulation dot1Q 10 native router subinterface command?
the VLAN ID
the subinterface number
the interface number
the subnet number
What operational mode should be used on a switch port to connect it to a router for router-on-a-stick inter-VLAN routing?
access
dynamic desirable
trunk
dynamic auto
