WGU D315 Network and Security -
Foundations; Questions with 100%
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
Sends data transmissions directly to the port of the destination device on the
network Correct Answer: switch
