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.
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
Wide Area Network (WAN) - ✔✔✔ Correct Answer > Spans a large
geographic area such as a state, province, or country
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
,Personal Area Network (PAN) - ✔✔✔ Correct Answer > provides
communication for devices owned by a single user that work over a
short distance
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.)
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
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)
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.
Virtualization - ✔✔✔ Correct Answer > Creates multiple "virtual" machines
on a single computing device
Hypervisor - ✔✔✔ Correct Answer > Software that enables a single computer
to run multiple operating systems simultaneously.
Type 1 Hypervisor (bare metal) - ✔✔✔ Correct Answer > Software to manage
virtual machines that is installed before any operating system is
installed.
Type 2 Hypervisor (hosted) - ✔✔✔ Correct Answer > A virtual machine
interface that's loaded on top of an existing OS.
