Answer 1

Questions 2011 pts

Ans ; MAC addresses

A bridge operate in both Physical layer and Data link layer.

As a physical layer device it regenerates the signal it receives. As a Data link layer device the Bridge can check the Physical addresses (MAC) contained in the frame.

IP adresses using in Network layer .So it is not applicable in Bridge

Question 2021

Ans ; The NIC has failed

if server has failed all other system cant access the server.

The OS needs a updation the Computer cannot be work properly.

If the Switch has failed all network system in the switch failed.

Question 2031;

Ans ;192.168.3.200

wwww.gleneclarke.com :-This is in Application layer.

00-02-3F-6B-25-13 ;-This is a MAC address .It I is in  Data link layer

192.168.3.200 : It is a IP Address , Operate in layer 3 ie Network Layer address

COMPUTER1 :It is a End User Device . Operate in Physical layer.

Question 2041:

Ans :Single mode Fiber . THe Single mode fiber's core size is smaller and carries light directly down the fiber. As a result light reflection created during light transmission decreases, lowering attenuation and allowing the signal to successfully travel over longer distance.

In multimode core size is five to six times longer in diameter than single mode ,which aloows much greater light gahering capacity and facilitates the use of cheaper electro optic devices. it has a traditionally limited transmission distance.

Question 2051

Ans : It is a Sublayer of the Data Link Layer

Question 2061 ;

Ans : Network Layer.

In physical layer Hub,Repeaters are used

In Data Link layer Switch , Bridge etc are used
