WGU D315 NETWORK AND SECURITY
FOUNDATION EXAM QUESTIONS AND
CORRECT ANSWERS| 2026 UPDATED
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
