WGU C172 Network and Security Network
Exam Review Questions and Answers
2024/2025
What does LAN stand for? - correct answer Local Area Network
What is a LAN? - correct answer Network of users that share computer resources in a
limited area
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
How are LANs defined? - correct answer They are defined by topology and protocol
It is a network of users that share computer resources in a limited area. - correct
answer LAN
A type of network adapter used in desktop computers - correct answer network
interface card or NIC
Can be a NIC inserted into an expansion slot on the computers motherboard - correct
answer A wired network adapter
Where does a PC Card adapter connect to? - correct answer Notebook computers
What does a PC card adapter do? - correct answer provides an RJ-45 jack for
connecting to wired networks
The PC card adapter supports connects to which networks? - correct answer Both 10
mbps and 100 mbps networks
,What are private addresses? - correct answer IP addresses set aside for use in private
intranets
Intranets - correct answer An internal network that provides file and resource sharing
but is not accessed from the Internet
Are private addresses routeable? - correct answer No, because they are not public
IP internetwork - correct answer A network that uses IP addressing for identifying
devices connected to the network
TCP/IP - correct answer Transmission Control Protocol/Internet Protocol, the protocol
suite used for internetworks such as the Internet
Which 802.11x wireless technologies are compatible? - correct answer b,g, and n
When there is a combination of wireless b, g, and/or n technologies, which frequency
will be set for the combined technologies? - correct answer The slowest speed
Where does a wireless n adapter insert into? - correct answer A notebook or laptop
computer PC card slot
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."
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
