CISSP DOMAIN 4 COMMUNICATION
AND NETWORK SECURITY WITH
ANSWERS
Address Resolution Protocol (ARP) - CORRECT ANSWER-Is
used at the Media Access Control (MAC) Layer to provide for
direct communication between two devices within the same
LAN segment.
Bit - CORRECT ANSWER-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) - CORRECT ANSWER-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 - CORRECT ANSWER-Layer 2 devices that filter traffic
between segments based on Media Access Control (MAC)
addresses.
Cellular network - CORRECT ANSWER-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) - CORRECT ANSWER-
Every call's data is encoded with a unique key, then the calls
are all transmitted at once.
, Concentrators - CORRECT ANSWER-Multiplex connected
devices into one signal to be transmitted on a network.
Content Distribution Network
(CDN) - CORRECT ANSWER-Is a large distributed system of
servers deployed in multiple data centers across the internet.
Dynamic or Private Ports - CORRECT ANSWER-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) - CORRECT ANSWER-A
lightweight encapsulation protocol and lacks the reliable data
transport of the TCP layer.
Firewalls - CORRECT ANSWER-Devices that enforce
administrative security policies by filtering incoming traffic
based on a set of rules.
Frame - CORRECT ANSWER-Data represented at Layer 2 of
the Open Systems Interconnection (OSI) model.
Global System for Mobiles (GSM) - CORRECT ANSWER-Each
call is transformed into digital data that is given a channel and a
time slot.
Internet Control Message Protocol (ICMP) - CORRECT
ANSWER-Provides a means to send error messages and a
way to probe the network to determine network availability.
Internet Group Management Protocol (IGMP) - CORRECT
ANSWER-Used to manage multicasting groups that are a set of
hosts anywhere on a network that are listening for a
transmission.
