FOUNDATIONS PA AND OA EXAM 2026
COMPLETE QUESTIONS WITH ANSWERS
◉ LAN. Answer: Local Area Network
◉ In terms of protocol and the topology used for accessing the
network.. Answer: How are Local Area Networks defined?
◉ Protocol. Answer: A set of rules established for users to exchange
information
◉ Topology. Answer: The network architecture used to interconnect
the networking equipment.
◉ Ring, Bus, and Star. Answer: What are the most common
topologies for LANs?
◉ Token Ring topology. Answer: Uses a token that is placed in the
data channel and circulates around the ring.
◉ Token Ring Topology. Answer: A deterministic network
,◉ Deterministic. Answer: Each station connected to the network
ensures access for transmission of its messages at regular or fixed
time intervals
◉ 1. If an error changes the token pattern, it can cause the token to
stop circulating.. Answer: What are the disadvantages of the Token
Ring system?
◉ 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.. Answer: What is a disadvantage of the Token Ring
system from the troubleshooting and maintenance?
◉ Connect each computer or device on the network to a central
token ring hub.. Answer: What is a solution to the troubleshooting
and maintenance disadvantages of the Token Ring system?
◉ Token ring hub. Answer: A device that manages the passing of the
token instead of relying on individual computers to pass it.
◉ It improves the reliability of the network.. Answer: How does the
token ring hub improve the network?
,◉ Bus topology. Answer: Topology whereas the computers share the
media or coaxial cable for data transmission.
◉ ThinNet. Answer: The coaxial cable that is looped through each
networking device to transmit data in a bus topology
◉ Bus topology. Answer: In this topology, all devices on the network
can see each other's data traffic.
◉ Bus topology. Answer: 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.
◉ "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.". Answer: What are the
disadvantages of a bus topology?
◉ Bus topology. Answer: Which topology is seldomly used in
modern networks?
◉ Star topology. Answer: What is the most common topology used in
today's LANs?
, ◉ Star topology. Answer: Topology that uses twisted-pair cables
with modular plugs to connect computers and other networking
devices.
◉ Star. Answer: Topology whereas each device is connected to a
switch or hub
◉ star. Answer: A switch or hub facilitates the transfer of data
between networking devices in this topology
◉ hub. Answer: Transmits data to all the devices connected in the
star network
◉ hub. Answer: Also called a multiport repeater
◉ hub. Answer: Not meant for large networks, but are still used in
some smaller, slower speed LANs
◉ broadcast. Answer: A transmission from a hub in a star network
to all the devices in the network connected to the hub
◉ switch. Answer: Stores the hardware or physical address for each
device connected to its ports in a star network
