CORRECT DETAILED ANSWERS
WGU D315 NETWORK AND SECURITY FOUNDATIONS OJECTIVE ASSESMENT EXAM

Q: What are the disadvantages of the Token Ring system? - ANSWER-1. If an error changes the
token pattern, it can cause the token to stop circulating.



Q: What is a disadvantage of the Token Ring system from the troubleshooting and
maintenance? - 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.



Q: What is a solution to the troubleshooting and maintenance disadvantages of the Token Ring
system? - ANSWER-Connect each computer or device on the network to a central token ring
hub.



Q: A device that manages the passing of the token instead of relying on individual computers to
pass it. - ANSWER-Token ring hub



Q: How does the token ring hub improve the network? - ANSWER-It improves the reliability of
the network.



Q: Topology whereas the computers share the media or coaxial cable for data transmission. -
ANSWER-Bus topology

Q: The coaxial cable that is looped through each networking device to transmit data in a bus
topology - ANSWER-ThinNet



Q: In this topology, all devices on the network can see each other's data traffic. - ANSWER-Bus
topology



Q: 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. - ANSWER-Bus topology



Q: What are the disadvantages of a bus topology? - 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."

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



Q: Local Area Network - ANSWER-LAN



Q: How are Local Area Networks defined? - ANSWER-In terms of protocol and the topology
used for accessing the network.



Q: A set of rules established for users to exchange information - ANSWER-Protocol



Q: The network architecture used to interconnect the networking equipment. - ANSWER-
Topology



Q: What are the most common topologies for LANs? - ANSWER-Ring, Bus, and Star

Q: Uses a token that is placed in the data channel and circulates around the ring. - ANSWER-
Token Ring topology



Q: A deterministic network - ANSWER-Token Ring Topology



Q: Each station connected to the network ensures access for transmission of its messages at
regular or fixed time intervals - ANSWER-Deterministic




Q: Which topology is seldomly used in modern networks? - ANSWER-Bus topology



Q: What is the most common topology used in today's LANs? - ANSWER-Star topology



Q: Topology that uses twisted-pair cables with modular plugs to connect computers and other
networking devices. - ANSWER-Star topology



Q: Topology whereas each device is connected to a switch or hub - ANSWER-Star



Q: A switch or hub facilitates the transfer of data between networking devices in this topology -
ANSWER-star



Q: Transmits data to all the devices connected in the star network - ANSWER-hub



Q: Also called a multiport repeater - ANSWER-hub

Q: Not meant for large networks, but are still used in some smaller, slower speed LANs -
ANSWER-hub



Q: A transmission from a hub in a star network to all the devices in the network connected to
the hub - ANSWER-broadcast



Q: Stores the hardware or physical address for each device connected to its ports in a star
network - ANSWER-switch



Q: Sends data transmissions directly to the port of the destination device on the network -
ANSWER-switch



Q: The physical input/output interfaces to the networking hardware - ANSWER-port



Q: Where the cables physically connect to each other or a central switch or hub - ANSWER-Port



Q: Only the intended destination device on this network will see the data traffic - ANSWER-star



Q: What is an advantage of the star topology? - ANSWER-It improves the efficiency of the
available bandwidth of the network



Q: What is an advantage of the star topology from the troubleshooting and maintenance? -
ANSWER-A device can be removed or added without disrupting other devices on the network



Q: All devices are connected to each other - ANSWER-mesh topology
