WGU D315 UPDATED ACTUAL QUESTIONS
AND CORRECT ANSWERS
COMPREHENSIVE STUDY GUIDE
●● Local Area Network
Answer: LAN
●● How are Local Area Networks defined?
Answer: In terms of protocol and the topology used for accessing the
network.
●● A set of rules established for users to exchange information
Answer: Protocol
●● The network architecture used to interconnect the networking
equipment.
Answer: Topology
●● What are the most common topologies for LANs?
Answer: Ring, Bus, and Star
,●● Uses a token that is placed in the data channel and circulates around
the ring.
Answer: Token Ring topology
●● A deterministic network
Answer: Token Ring Topology
●● Each station connected to the network ensures access for
transmission of its messages at regular or fixed time intervals
Answer: Deterministic
●● What are the disadvantages of the Token Ring system?
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?
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?
,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.
Answer: Token ring hub
●● How does the token ring hub improve the network?
Answer: It improves the reliability of the network.
●● Topology whereas the computers share the media or coaxial cable for
data transmission.
Answer: Bus topology
●● The coaxial cable that is looped through each networking device to
transmit data in a bus topology
Answer: ThinNet
●● In this topology, all devices on the network can see each other's data
traffic.
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.
Answer: Bus topology
●● What are the disadvantages of a bus topology?
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?
Answer: Bus topology
●● What is the most common topology used in today's LANs?
Answer: Star topology
●● Topology that uses twisted-pair cables with modular plugs to connect
computers and other networking devices.
Answer: Star topology
●● Topology whereas each device is connected to a switch or hub
Answer: Star
