WGU C172 Network and Security -

Foundations; PA and OA set Exam

Questions and Answers


It is a network of users that share computer resources in a limited area. - ANSWER✔✔-LAN


Local Area Network - ANSWER✔✔-LAN


How are Local Area Networks defined? - ANSWER✔✔-In terms of protocol and the topology used for

accessing the network.


A set of rules established for users to exchange information - ANSWER✔✔-Protocol


The network architecture used to interconnect the networking equipment. - ANSWER✔✔-Topology


What are the most common topologies for LANs? - ANSWER✔✔-Ring, Bus, and Star


Uses a token that is placed in the data channel and circulates around the ring. - ANSWER✔✔-Token Ring

topology


A deterministic network - ANSWER✔✔-Token Ring Topology


Each station connected to the network ensures access for transmission of its messages at regular or fixed

time intervals - ANSWER✔✔-Deterministic


What are the disadvantages of the Token Ring system? - 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? -

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? -

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. -

ANSWER✔✔-Token ring hub


How does the token ring hub improve the network? - ANSWER✔✔-It improves the reliability of the

network.


Topology whereas the computers share the media or coaxial cable for data transmission. - ANSWER✔✔-

Bus topology


The coaxial cable that is looped through each networking device to transmit data in a bus topology -

ANSWER✔✔-ThinNet


In this topology, all devices on the network can see each other's data traffic. - 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. - ANSWER✔✔-Bus

topology


What are the disadvantages of a bus topology? - 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? - ANSWER✔✔-Bus topology


What is the most common topology used in today's LANs? - ANSWER✔✔-Star topology


Topology that uses twisted-pair cables with modular plugs to connect computers and other networking

devices. - ANSWER✔✔-Star topology


Topology whereas each device is connected to a switch or hub - ANSWER✔✔-Star


A switch or hub facilitates the transfer of data between networking devices in this topology -

ANSWER✔✔-star


Transmits data to all the devices connected in the star network - ANSWER✔✔-hub


Also called a multiport repeater - ANSWER✔✔-hub


Not meant for large networks, but are still used in some smaller, slower speed LANs - ANSWER✔✔-hub


A transmission from a hub in a star network to all the devices in the network connected to the hub -

ANSWER✔✔-broadcast


Stores the hardware or physical address for each device connected to its ports in a star network -

ANSWER✔✔-switch


Sends data transmissions directly to the port of the destination device on the network - ANSWER✔✔-

switch


The physical input/output interfaces to the networking hardware - ANSWER✔✔-port


Where the cables physically connect to each other or a central switch or hub - ANSWER✔✔-Port


Only the intended destination device on this network will see the data traffic - ANSWER✔✔-star
