Which network device is considered passive in terms of how it
connects to other devices? - ✔✔✔ Correct Answer > Hub
Which port number does the file transfer protocol (FTP) use? -
✔✔✔ Correct Answer > 21
Which networking device can be programmed to make
decisions to send packets from an input port to an output port
based on IP addresses? - ✔✔✔ Correct Answer > A router uses
routing protocols to route packets from one input port to an
output port.
Wide Area Network (WAN) - ✔✔✔ Correct Answer > Spans a large
geographic area such as a state, province, or country
,Page 2 of 49
Which network device offers the capability of centralizing the
control of resources and compartmentalizing files for
improved reliability? - ✔✔✔ Correct Answer > Servers perform
critical roles such as providing authentication and providing
files to users.
What do networks use to communicate with resources and
manage the flow of data across the network? - ✔✔✔ Correct Answer
> Network operating system (NOS)
Which network resources can be on the cloud or over the
internet? - ✔✔✔ Correct Answer > 1. applications
2. disk storage
Applications can reside on a remote computer and can be
accessed over the cloud.
A server can be allocated to store data and files over the cloud.
Metropolitan Area Network (MAN) - ✔✔✔ Correct Answer > A large
computer network usually spanning a city
Local Area Network (LAN) - ✔✔✔ Correct Answer > Connects a
group of computers in close proximity, such as in an office
building, school, or home
,Page 3 of 49
Personal Area Network (PAN) - ✔✔✔ Correct Answer > provides
communication for devices owned by a single user that work
over a short distance
Virtual radio access network (vRAN) - ✔✔✔ Correct Answer >
Which type of network connects devices within the ranges of
30 feet or less? - ✔✔✔ Correct Answer > Personal area network
(PAN)
Mesh Topology - ✔✔✔ Correct Answer > Devices are connected with
many redundant interconnections between network nodes.
Bus Topology - ✔✔✔ Correct Answer > A network layout in which
there is one main trunk, or backbone, that all the various
computers and network devices are connected to.
Star Topology - ✔✔✔ Correct Answer > A topology with one central
node that has each computer or network device attached to
the central node. All data first goes into the central node and
then is sent out to its destination. (Think of it like a bicycle
wheel with spokes.)
, Page 4 of 49
Ring Topology - ✔✔✔ Correct Answer > Topology where the
computers are connected on a loop or ring. Data flows in one
direction only.
Gateways - ✔✔✔ Correct Answer > Nodes on a network that serves
as an entrance to another network
Bridges - ✔✔✔ Correct Answer > Layer 2 devices that filter traffic
between segments based on Media Access Control (MAC)
addresses.
Firewall - ✔✔✔ Correct Answer > a part of a computer system or
network that is designed to block unauthorized access while
permitting outward communication.
What is the security device that protects a network from
hackers and can also simultaneously prevent computers within
the network from accessing undesirable content on the
internet? -
✔✔✔ Correct Answer > Firewalls filter and inspect inbound and
outbound packets based on rules configured by the
administrator.
Virtualization - ✔✔✔ Correct Answer > Creates multiple "virtual"
machines on a single computing device
