WGU D315 NETWORK AND SECURITY - FOUNDATIONS FINAL
OBJECTIVE ASSESSMENT 2024/2025(ALL POSSIBLE LATEST QUESTIONS
WITH A+ GRADE ANSWERS)
It is a network of users that share computer resources in a limited area. (correct answers)LAN
Local Area Network (correct answers)LAN
How are Local Area Networks defined? (correct answers)In terms of protocol and the topology used for
accessing the network.
A set of rules established for users to exchange information (correct answers)Protocol
The network architecture used to interconnect the networking equipment. (correct answers)Topology
What are the most common topologies for LANs? (correct answers)Ring, Bus, and Star
Uses a token that is placed in the data channel and circulates around the ring. (correct answers)Token
Ring topology
A deterministic network (correct answers)Token Ring Topology
Each station connected to the network ensures access for transmission of its messages at regular or fixed
time intervals (correct answers)Deterministic
What are the disadvantages of the Token Ring system? (correct answers)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
answers)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 answers)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 answers)Token ring hub
How does the token ring hub improve the network? (correct answers)It improves the reliability of the
network.
Topology whereas the computers share the media or coaxial cable for data transmission. (correct
answers)Bus topology
The coaxial cable that is looped through each networking device to transmit data in a bus topology
(correct answers)ThinNet
In this topology, all devices on the network can see each other's data traffic. (correct answers)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 answers)Bus
topology
What are the disadvantages of a bus topology? (correct answers)"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 answers)Bus topology
What is the most common topology used in today's LANs? (correct answers)Star topology
, Topology that uses twisted-pair cables with modular plugs to connect computers and other networking
devices. (correct answers)Star topology
Topology whereas each device is connected to a switch or hub (correct answers)Star
A switch or hub facilitates the transfer of data between networking devices in this topology (correct
answers)star
Transmits data to all the devices connected in the star network (correct answers)hub
Also called a multiport repeater (correct answers)hub
Not meant for large networks, but are still used in some smaller, slower speed LANs (correct
answers)hub
A transmission from a hub in a star network to all the devices in the network connected to the hub
(correct answers)broadcast
Stores the hardware or physical address for each device connected to its ports in a star network (correct
answers)switch
Sends data transmissions directly to the port of the destination device on the network (correct
answers)switch
The physical input/output interfaces to the networking hardware (correct answers)port
Where the cables physically connect to each other or a central switch or hub (correct answers)Port
Only the intended destination device on this network will see the data traffic (correct answers)star
