第2题:
With regard to Ethernet media access methods, which of the following are true?
(Choose all that apply.)
A.A device waits for an electronic signal before transmitting.
B.A device listens and waits until the media is not busy before transmitting.
C.All devices on an Ethernet segment see data that passes on the network medium.
D.Only the sender and the receiver devices see data that passes on the network medium.
E.Ethernet networks allow you to configured devises with higher transmission priority.
第3题:
IP multicasting is a set of technologies that enable efficient delivery of data to many locations
on a network. Rather than making multiple copies of a message intended to be distributed
to multiple recipients at the __(71)__ of origin of a message, multicasting initially sends just
one __(72)__ and does not copy it to the individual recipients until it reaches the closest common point
on the network, thereby __(73)__ the bandwidth consumed. Network performance is significantly
(74) because it isn’t bogged down with the processing and transmission of several large data files;
each receiving computer doesn’t have to __(75)__ the transmitting server for the file.
(71)
A. point
B. bottom
C. head
D. sight
