Question

40. Unlike a hub LAN, a switched LAN a. provides each node with me full network bandwidth b. forwards all traffic to each port of the switch c. requires a software upgrade to each node connected d. all of the above 41. Coaxial cable is less susceptible to interference and cross-talk because a. it is constructed with a shield b. it uses a dielectric material C. it has a stronger insulator d. it uses a higher grade of copper 42. Carrier sense multiple access with collision detection is an access method that requires nodes to a transmit when the line is idle or wait others are done b. receive a special frame that allows them to transmit c. collide with other transmissions to assert a level of priority d. all of the above

Explanation / Answer

40)

Hub sends the incoming packets to all the output ports. But Switch sends the incoming packet to one or more output ports. Therefore switches provides high bandwidth. So, the correct answer is (a).

41)

Coaxial cable is less susceptible to interference and cross-talk because they of the shield.

Therefore, the correct answer is (a).

42)

Carrier Sense Multiple Access with Collision Detection (CSMA/CD) is an access method that requires nodes to transmit when the line is idle or wait others are done.

Therefore, the correct answer is (a).
