Ethernet networks can be cabled in a number of topologies, depending on what works best in each environment. As more nodes are added, the efficiency of Ethernet decreases. Select the best answer as to why Ethernet becomes less efficient as size increases.

A

Network collisions occur

B

Repeaters cannot increase the signal strength sufficiently

C

Cable terminators do not reflect the signal properly

D

Cable terminators do not absorb the signal properly

E

"Line echo" occurs due to the impedance of the cable

The MAC (Media Access Control) address of the network card is used in both Ethernet and Token-Ring networks and is essential for communication. What does MAC provide?

A physical address that is randomly assigned each time the computer is started

C

A physical address that is assigned by the manufacturer

D

The logical domain address for the workstation

E

An alias for the computer name

There are two domains on your network. The DESIGN domain trusts the SALES domain. A color printer is shared in the DESIGN domain, and print permissions have been granted to the Domain Users and Domain Guests groups in the DESIGN domain. The Guest account has been enabled in the DESIGN domain. User John Y logs on using his account in the SALES domain. What must you do to allow JohnY to access the printer?

A

Make JohnY a member of the DESIGN Domain Guests group

B

Make JohnY a member of the DESIGN Domain Users group

C

Do nothing. JohnY can access the printer now

D

JohnY cannot access the printer with this configuration

E

None of the above

Ethernet and Token-Ring are the two most commonly used network architectures in the world. Jim has heard of the different topologies for networks and wants to choose the architecture that will provide him with the most options. Which of the following would that be? Choose the most correct answer.

A

Token-Ring because it currently can run at both 4Mbps and 16Mbps. This means that it can be used in any topology

B

Ethernet, because it is cabled using fiber-optic cable

C

Token-Ring, because it uses a MAU

D

Ethernet, because it can be set up with most topologies and can use multiple transfer speeds

E

Neither Token-Ring nor Ethernet is the proper choice. Only ARCnet can be used in all topologies
