Cisco I     IC 112906


Compare the following :

10BASE 5 and 10BASE T

10 BASE 5 has a higher segment length (500 meters) but only supports coaxial cable
10 BASE T has a lower segment length (100 meters) but supports CAT 3,4, and 5 UTP cable 

100BASE-TX and 100BASE-FX

100 BASE TX has a lower segment length (100 meters) but only supports CAT 5 UTP
100 BASE FX has a higher segment length (400 meters) and supports 62.5/125 fiber optic cable

Why would a network administrator choose to implement Gigabit Ethernet
from the backbone to the end user ?

higher bandwith provides high speed file transfer, maybe for a person who needs a high amount of bandwith because of the nature of his job i.e. computer graphics artist

On what type of network device are you likely to find “serial 1/0”

Router

What does IEEE 802.3 describe \?

Ethernet LAN type i.e. 802.3u Fast Ethernet


How many pins does an AUI port have?

15 pins

A repeater allows multiple hosts to be connected by taking an
incoming signal and generating a new, clean network signal.

Why doesn’t the repeater simply amplify the incoming signal?

Because the signal would be amplified after its distortion/deterioration took place,
Making a large deteriorated signal and transmitting the deteriorated signal along the rest of the network.

Peer to peer and client – server are 2 types of networks

Switches build data tables to make decisions on how to deal with data frames.
Name 2 pieces of information contained within these tables.

The interface and the MAC address

Switches operate at which layer of the OSI model?

Data-Link

A network associate is performing an initial configuration on a new Cisco 2811
router.  Which port on the router will be used to perform this task?

serial port (DB-60)

MAC is associated with which layer of the OSI model?

How do you connect an AUI port on a Cisco 2500 router to a CAT 5 ethernet 
cable?

Use a transceiver that converts an AUI to an RJ-45

Which device has a higher latency – switches or bridges? Why?
