Which statement is true about broadcast and collision domains?
a)
Adding a switch to a network will increase the size of the broadcast domain
b)
Adding a router to a network will increase the size of the collision domain
c)
The more interfaces a router has the larger the resulting broadcast domain
d)
The size of the collision domain can be reduced by adding hubs to a network
e)
Adding a switch to a network will decrase the size of the broadcast domain
2.
What is one function of a Layer 2 switch?
a)
Duplicates the electrical signal of each frame to every portt
b)
Learns the port assigned to a hostt by examining the destination MAC address
c)
Determines which interface is used to forward a frame on the destination MAC address

To manage the layer 3 packets

Which two statements are true about half-duplex and full-duplex communications? (Choose two.)
a)
Full duplex offers 100% potential use of the bandwidth
b)
Half duplex has only one channel
c)
Full duplex allows both ends to transmit and receive simultaneously

10.
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?
a)
Drop the frame
b)
Forward the frame out all ports except the port where the frame is received
c)
Send the frame to the default gateway address
d)
Use ARP to resolve the port that is related to the frame

It is assigned to a physical port and can be connected to other devices
c)
The no shutdown command is required to place it in the UP state
d)
It is a logical interface internal to the router
13.
Which characteristic describes cut-through switching?
a)
Error-free fragments are forwarded, so switching occurs with lower latency
