WGU D315 UPDATED ACTUAL
Questions and CORRECT Answers
It is a network of users that share computer resources in a limited area. - CORRECT
ANSWER - LAN



Local Area Network - 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
