OFFICIAL (ISC)² CISSP - DOMAIN 4: COMMUNICATION AND
NETWORK SECURITY EXAM 2024 QUESTIONS WITH COMPLETE
SOLUTIONS VERIFIED
Address Resolution Protocol (ARP)
Is used at the Media Access Control (MAC) Layer to provide for direct communication
between two devices within the same LAN segment.
Bit
Most essential representation of data (zero or one) at Layer 1 of the Open Systems
Interconnection (OSI) model.
Bluetooth (Wireless Personal Area
Network IEEE 802.15)
Bluetooth wireless technology is an open standard for short-range radio frequency
communication used primarily to establish wireless personal area networks (WPANs),
and it has been integrated into many types of business and consumer devices.
Bridges
Layer 2 devices that filter traffic between segments based on Media Access Control
(MAC) addresses.
Cellular network
A radio network distributed over land areas called cells, each served by at least one
fixed-location transceiver, known as a cell site or base station.
Code-division multiple access (CDMA)
Every call's data is encoded with a unique key, then the calls are all transmitted at once.
Concentrators
Multiplex connected devices into one signal to be transmitted on a network.
, Content Distribution Network
(CDN)
Is a large distributed system of servers deployed in multiple data centers across the
internet.
Dynamic or Private Ports
Ports 49152 - 65535. Whenever a service is requested that is associated with Well-
Known or Registered Ports those services will respond with a dynamic port.
Fibre Channel over Ethernet (FCoE)
A lightweight encapsulation protocol and lacks the reliable data transport of the TCP
layer.
Firewalls
Devices that enforce administrative security policies by filtering incoming traffic based
on a set of rules.
Frame
Data represented at Layer 2 of the Open Systems Interconnection (OSI) model.
Global System for Mobiles (GSM)
Each call is transformed into digital data that is given a channel and a time slot.
Internet Control Message Protocol (ICMP)
Provides a means to send error messages and a way to probe the network to determine
network availability.
Internet Group Management Protocol (IGMP)
Used to manage multicasting groups that are a set of hosts anywhere on a network that
are listening for a transmission.
Multiprotocol Label Switching (MPLS)
Is a wide area networking protocol that operates at both Layer 2 and 3 and does label
switching.
OSI Layer 1
Physical Layer
OSI Layer 2
Data-Link Layer
OSI Layer 3
