SECURITY FOUNDATIONS) PA&OA
EXAM |GUARANTEED

It is a network of users that share computer resources in a limited area. -
ACCURATE ANSWERS✔✔ LAN


Local Area Network - ACCURATE ANSWERS✔✔ LAN


How are Local Area Networks defined? - ACCURATE ANSWERS✔✔
In terms of protocol and the topology used for accessing the network.


A set of rules established for users to exchange information -
ACCURATE ANSWERS✔✔ Protocol


The network architecture used to interconnect the networking
equipment. - ACCURATE ANSWERS✔✔ Topology


What are the most common topologies for LANs? - ACCURATE
ANSWERS✔✔ Ring, Bus, and Star


Uses a token that is placed in the data channel and circulates around the
ring. - ACCURATE ANSWERS✔✔ Token Ring topology

,A deterministic network - ACCURATE ANSWERS✔✔ Token Ring
Topology


Each station connected to the network ensures access for transmission of
its messages at regular or fixed time intervals - ACCURATE
ANSWERS✔✔ Deterministic


What are the disadvantages of the Token Ring system? - ACCURATE
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? - ACCURATE 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? - ACCURATE 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. - ACCURATE ANSWERS✔✔ Token
ring hub


How does the token ring hub improve the network? - ACCURATE
ANSWERS✔✔ It improves the reliability of the network.

,Topology whereas the computers share the media or coaxial cable for
data transmission. - ACCURATE ANSWERS✔✔ Bus topology


The coaxial cable that is looped through each networking device to
transmit data in a bus topology - ACCURATE ANSWERS✔✔ ThinNet


In this topology, all devices on the network can see each other's data
traffic. - ACCURATE 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. - ACCURATE ANSWERS✔✔ Bus
topology


What are the disadvantages of a bus topology? - ACCURATE
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? - ACCURATE
ANSWERS✔✔ Bus topology


What is the most common topology used in today's LANs? -
ACCURATE ANSWERS✔✔ Star topology

, Topology that uses twisted-pair cables with modular plugs to connect
computers and other networking devices. - ACCURATE ANSWERS✔✔
Star topology


Topology whereas each device is connected to a switch or hub -
ACCURATE ANSWERS✔✔ Star


A switch or hub facilitates the transfer of data between networking
devices in this topology - ACCURATE ANSWERS✔✔ star


Transmits data to all the devices connected in the star network -
ACCURATE ANSWERS✔✔ hub


Also called a multiport repeater - ACCURATE ANSWERS✔✔ hub


Not meant for large networks, but are still used in some smaller, slower
speed LANs - ACCURATE ANSWERS✔✔ hub


A transmission from a hub in a star network to all the devices in the
network connected to the hub - ACCURATE ANSWERS✔✔ broadcast


Stores the hardware or physical address for each device connected to its
ports in a star network - ACCURATE ANSWERS✔✔ switch


Sends data transmissions directly to the port of the destination device on
the network - ACCURATE ANSWERS✔✔ switch
