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
