NETWORK AND SECURITY FOUNDATIONS
EXAM STUDY SHEET 2026 TEST PAPER
◉ Wireless Local Area Network (WLAN) Answer: A LAN with
wireless connectivity
◉ Storage Area Network (SAN) Answer: A network that allows
access to storage devices specifically instead of the more general
networking that can be used for any purpose.
◉ Campus Area Network (CAN) Answer: A network that provides
networking of multiple LANs across a limited area, like a university
campus or a group of buildings owned by a company
◉ Metropolitan Area Network (MAN) Answer: A network that
provides networking across a larger area, such as a whole city or the
equivalent of a metropolitan area, though it is not necessarily limited
by city boundaries.
◉ Wide Area Network (WAN) Answer: Anetwork that covers a large
geographical area within its network. This would be the case for
worldwide businesses or government bodies
,◉ client/server network Answer: A network that uses centrally
administered computers, known as servers, to enable resource
sharing for and to facilitate communication between the other
computers on the network.
◉ peer-to-peer network Answer: A type of network that connects
two client computers directly together.
◉ Bus Topology Answer: Network configuration wherein all
computers connect to the network via a central bus cable.
◉ Ring Topology Answer: Topology where the computers are
connected on a loop or ring. Data flows in one direction only.
◉ Star Topology 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.)
◉ Mesh Topology Answer: Devices are connected with many
redundant interconnections between network nodes.
◉ Presentation layer of the OSI model (Q/A) Answer: Character
encoding, data compression and encryption/decryption take place
at the
, ◉ Data link layer (Q/A) Answer: In the OSI model, Media Access
Control (MAC) and Logical Link Control (LLC) sublayers are the
components of:
◉ Centralized Answer: Networks where computing and network
power is centralized in a large, secure data center where users log
on to dumb terminals to access mainframe data and perform tasks.
◉ Decentralized Answer: Networks that rely on the computing
power in the user's device and enable users to operate without a
network connection and be portable.
◉ Hypervisor Answer: A software tool used to host virtual systems
◉ Hypervisor type 1 Answer: Operating systems that natively run
virtual machines and are intended to be installed on a dedicated
bare metal server
◉ Hypervisor Type 2 Answer: An installed as an application within
another operating system environment that allows the use of virtual
machines from within that same environment.
