WGU C172 Network and Security - Foundations; PA and
OA set Exam Questions and Answers Rated A+ 2026
It is a network of users that share computer resources in a limited area. - ans
LAN
Local Area Network - ans LAN
How are Local Area Networks defined? - ans In terms of protocol and the
topology used for accessing the network.
A set of rules established for users to exchange information - ans Protocol
The network architecture used to interconnect the networking equipment. -
ans Topology
What are the most common topologies for LANs? - ans Ring, Bus, and
Star
,Uses a token that is placed in the data channel and circulates around the
ring. - ans Token Ring topology
A deterministic network - ans Token Ring Topology
Each station connected to the network ensures access for transmission of its
messages at regular or fixed time intervals - ans Deterministic
What are the disadvantages of the Token Ring system? - ans 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? - ans 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? - ans 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. - ans Token ring hub
How does the token ring hub improve the network? - ans It improves the
reliability of the network.
Topology whereas the computers share the media or coaxial cable for data
transmission. - ans Bus topology
The coaxial cable that is looped through each networking device to transmit
data in a bus topology - ans ThinNet
In this topology, all devices on the network can see each other's data traffic.
- ans 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. - ans Bus topology
, What are the disadvantages of a bus topology? - ans "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? - ans Bus
topology
What is the most common topology used in today's LANs? - ans Star
topology
Topology that uses twisted-pair cables with modular plugs to connect
computers and other networking devices. - ans Star topology
Topology whereas each device is connected to a switch or hub - ans Star
