WGU D315 Network And Security - Foundations; PA
And OA Set (Questions With A+ Solutions)
It is a network of users that share computer resources in a limited area.
Right Ans - LAN
How are Local Area Networks defined? Right Ans - In terms of protocol
and the topology used for accessing the network.
A set of rules established for users to exchange information Right Ans -
Protocol
The network architecture used to interconnect the networking equipment.
Right Ans - Topology
What are the most common topologies for LANs? Right Ans - Ring, Bus,
and Star
Uses a token that is placed in the data channel and circulates around the
ring. Right Ans - Token Ring topology
A deterministic network Right Ans - Token Ring Topology
Each station connected to the network ensures access for transmission of
its messages at regular or fixed time intervals Right Ans - Deterministic
What are the disadvantages of the Token Ring system? Right Ans - 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? Right Ans - 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? Right Ans - 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. Right Ans - Token ring hub
How does the token ring hub improve the network? Right Ans - It
improves the reliability of the network.
Topology whereas the computers share the media or coaxial cable for data
transmission. Right Ans - Bus topology
The coaxial cable that is looped through each networking device to
transmit data in a bus topology Right Ans - ThinNet
In this topology, all devices on the network can see each other's data traffic.
Right Ans - 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. Right Ans - Bus topology
What are the disadvantages of a bus topology? Right Ans - "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? Right Ans - Bus
topology
What is the most common topology used in today's LANs? Right Ans -
Star topology
Topology that uses twisted-pair cables with modular plugs to connect
computers and other networking devices. Right Ans - Star topology
Topology whereas each device is connected to a switch or hub Right Ans
- Star
, A switch or hub facilitates the transfer of data between networking devices
in this topology Right Ans - star
Transmits data to all the devices connected in the star network Right
Ans - hub
Also called a multiport repeater Right Ans - hub
Not meant for large networks, but are still used in some smaller, slower
speed LANs Right Ans - hub
A transmission from a hub in a star network to all the devices in the
network connected to the hub Right Ans - broadcast
Stores the hardware or physical address for each device connected to its
ports in a star network Right Ans - switch
Sends data transmissions directly to the port of the destination device on
the network Right Ans - switch
The physical input/output interfaces to the networking hardware Right
Ans - port
Where the cables physically connect to each other or a central switch or
hub Right Ans - Port
Only the intended destination device on this network will see the data
traffic Right Ans - star
What is an advantage of the star topology? Right Ans - It improves the
efficiency of the available bandwidth of the network
What is an advantage of the star topology from the troubleshooting and
maintenance? Right Ans - A device can be removed or added without
disrupting other devices on the network
All devices are connected to each other Right Ans - mesh topology
