ACTUAL Questions and CORRECT
Answers
It is a network of users that share computer resources in a limited area. - CORRECT
ANSWER - LAN
How are Local Area Networks defined? - CORRECT ANSWER - In terms of protocol and
the topology used for accessing the network.
A set of rules established for users to exchange information - CORRECT ANSWER -
Protocol
The network architecture used to interconnect the networking equipment. - CORRECT
ANSWER - Topology
What are the most common topologies for LANs? - CORRECT ANSWER - Ring, Bus,
and Star
Uses a token that is placed in the data channel and circulates around the ring. - CORRECT
ANSWER - Token Ring topology
A deterministic network - CORRECT ANSWER - Token Ring Topology
Each station connected to the network ensures access for transmission of its messages at regular
or fixed time intervals - CORRECT ANSWER - Deterministic
What are the disadvantages of the Token Ring system? - CORRECT ANSWER - 1. If an
error changes the token pattern, it can cause the token to stop circulating.
,What is a disadvantage of the Token Ring system from the troubleshooting and maintenance? -
CORRECT ANSWER - The token ring path must be temporarily broken or interrupted if a
computer or any device on the network is to be removed or added to the network.
What is a solution to the troubleshooting and maintenance disadvantages of the Token Ring
system? - CORRECT ANSWER - Connect each computer or device on the network to a
central token ring hub.
A device that manages the passing of the token instead of relying on individual computers to
pass it. - CORRECT ANSWER - Token ring hub
How does the token ring hub improve the network? - CORRECT ANSWER - It improves
the reliability of the network.
Topology whereas the computers share the media or coaxial cable for data transmission. -
CORRECT ANSWER - Bus topology
The coaxial cable that is looped through each networking device to transmit data in a bus
topology - CORRECT ANSWER - ThinNet
In this topology, all devices on the network can see each other's data traffic. - CORRECT
ANSWER - Bus topology
Topology whereas each computer must wait for pauses in transmission or until the transmission
from one device is complete before initiating a new transmission onto the network. - CORRECT
ANSWER - Bus topology
What are the disadvantages of a bus topology? - CORRECT ANSWER - "1. Data can be
corrupted if ore than one device on the network transmits at the same time and will have to be
resubmitted.
, 2. The use of the shared coaxial cable prevents data transmission from being very bandwidth-
efficient."
Which topology is seldomly used in modern networks? - CORRECT ANSWER - Bus
topology
What is the most common topology used in today's LANs? - CORRECT ANSWER - Star
topology
Topology that uses twisted-pair cables with modular plugs to connect computers and other
networking devices. - CORRECT ANSWER - Star topology
Topology whereas each device is connected to a switch or hub - CORRECT ANSWER -
Star
A switch or hub facilitates the transfer of data between networking devices in this topology -
CORRECT ANSWER - star
Transmits data to all the devices connected in the star network - CORRECT ANSWER -
hub
Also called a multiport repeater - CORRECT ANSWER - hub
Not meant for large networks, but are still used in some smaller, slower speed LANs -
CORRECT ANSWER - hub
A transmission from a hub in a star network to all the devices in the network connected to the
hub - CORRECT ANSWER - broadcast
Stores the hardware or physical address for each device connected to its ports in a star network -
CORRECT ANSWER - switch
