WGU D315 NETWORK AND SECURITY
FOUNDATION TEST BANK QUESTIONS
WITH VERIFIED ANSWERS FULL REVIEW
●● Local Area Network
Answer: A network of users that share computer resources in a limited
area.
●● Definition of Local Area Networks
Answer: In terms of protocol and the topology used for accessing the
network.
●● Protocol
Answer: A set of rules established for users to exchange information.
●● Topology
Answer: The network architecture used to interconnect the networking
equipment.
●● Common topologies for LANs
Answer: Ring, Bus, and Star.
,●● Token Ring topology
Answer: Uses a token that is placed in the data channel and circulates
around the ring.
●● Deterministic network
Answer: A network where each station connected to the network ensures
access for transmission of its messages at regular or fixed time intervals.
●● Disadvantages of the Token Ring system
Answer: 1. If an error changes the token pattern, it can cause the token
to stop circulating.
●● Troubleshooting disadvantage of Token Ring
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.
●● Solution to Token Ring troubleshooting
Answer: Connect each computer or device on the network to a central
token ring hub.
●● Token ring hub
Answer: A device that manages the passing of the token instead of
relying on individual computers to pass it.
,●● Improvement by token ring hub
Answer: It improves the reliability of the network.
●● Bus topology
Answer: Topology whereas the computers share the media or coaxial
cable for data transmission.
●● ThinNet
Answer: The coaxial cable that is looped through each networking
device to transmit data in a bus topology.
●● Bus topology data visibility
Answer: In this topology, all devices on the network can see each other's
data traffic.
●● Bus topology transmission
Answer: 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.
●● Disadvantages of bus topology
Answer: 1. Data can be corrupted if more 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.
●● Seldom used topology
Answer: Bus topology.
●● Most common topology in today's LANs
Answer: Star topology.
●● Twisted-pair cables topology
Answer: Topology that uses twisted-pair cables with modular plugs to
connect computers and other networking devices.
●● Star topology
Answer: Topology whereas each device is connected to a switch or hub.
●● Hub
Answer: Transmits data to all the devices connected in the star network.
●● Hub
Answer: Also called a multiport repeater.
●● Hub
