When a collision occurs in a network using CSMA/CD, how do hosts with data to transmit respond after the backoff period has expired?

The hosts return to a listen-before-transmit mode.
The hosts creating the collision have priority to send data.
The hosts creating the collision retransmit the last 16 frames.
The hosts extend their delay period to allow for rapid transmission

Which statements correctly describe MAC addresses? (Choose three.)

dynamically assigned
 
copied into RAM during system startup

layer 3 address

contains a 3 byte OUI

6 bytes long

32 bits long

Why do hosts on an Ethernet segment that experience a collision use a random delay before attempting to transmit a frame?

A random delay is used to ensure a collision-free link.
A random delay value for each device is assigned by the manufacturer.
A standard delay value could not be agreed upon among networking device vendors. 
A random delay helps prevent the stations from experiencing another collision during the transmission.

What is considered a benefit of wireless as a media choice?

more host mobility
lower security risks
reduced susceptibility to interference
less impact of the surroundings on the effective coverage area

With the use of unshielded twisted-pair copper wire in a network, what causes crosstalk within the cable pairs?

the magnetic field around the adjacent pairs of wire
the use of braided wire to shield the adjacent wire pairs
the reflection of the electrical wave back from the far end of the cable
the collision caused by two nodes trying to use the media simultaneously
