PCCSA EXAM QUESTIONS AND
ANSWERS 2025
Address Resolution Protocol (ARP)
A protocol that translates a logical address, such as an IP address, to a
physical MAC address. The Reverse Address Resolution Protocol (RARP)
translates a physical MAC address to a logical address.
Advanced Encryption Standard (AES)
A symmetric block cipher based on the Rijndael cipher.

application programming interface (API)
A set of routines, protocols, and tools for building software applications
and integrations.
,application whitelisting
A technique used to prevent unauthorized applications from running on an
endpoint. Authorized applications are manually added to a list that is
maintained on the endpoint. If an application is not on the whitelist, it
cannot run on the endpoint. However, if it is on the whitelist the
application can run, regardless of whether vulnerabilities or exploits are
present within the application.
attack vector
A path or tool that an attacker uses to target a network.
authoritative DNS server
The system of record for a given domain.
autonomous system (AS)
A group of contiguous IP address ranges under the control of a single
internet entity. Individual _______ _______s are assigned a 16-bit or 32-bit AS
number (ASN) that uniquely identifies the network on the internet. ASNs
are assigned by the Internet Assigned Numbers Authority (IANA).
boot sector
Contains machine code that is loaded into an endpoint's memory by
firmware during the startup process, before the operating system is
loaded.
boot sector virus
,Targets the boot sector or master boot record (MBR) of an endpoint's
storage drive or other removable storage media.
bot
Individual endpoints that are infected with advanced malware that
enables an attacker to take control of the compromised endpoint. Also
known as a zombie.
botnet
A network of bots (often tens of thousands or more) working together
under the control of attackers using numerous command-and-control
(C&C) servers.
bridge
A wired or wireless network device that extends a network or joins
separate network segments.
bring your own apps (BYOA)
Closely related to BYOD, _________ is a policy trend in which organizations
permit end users to download, install, and use their own personal apps on
mobile devices, primarily smartphones and tablets, for work-related
purposes.
bring your own device (BYOD)
A policy trend in which organizations permit end users to use their own
personal devices, primarily smartphones and tablets, for work-related
purposes. _______ relieves organizations from the cost of providing
equipment to employees but creates a management challenge because of
the vast number and type of devices that must be supported.
, broadband cable
A type of high-speed internet access that delivers different upload and
download data speeds over a shared network medium. The overall speed
varies depending on the network traffic load from all the subscribers on
the network segment.
broadcast domain
The portion of a network that receives broadcast packets sent from a node
in the domain.
bulk electric system (BES)
The large interconnected electrical system, consisting of generation and
transmission facilities (among others), that comprises the "power grid."
bus (or linear bus) topology
A LAN topology in which all nodes are connected to a single cable (the
backbone) that is terminated on both ends. In the past, bus networks
were commonly used for very small networks because they were
inexpensive and relatively easy to install, but today bus topologies are
rarely used. The cable media has physical limitations (the cable length),
the backbone is a single point of failure (a break anywhere on the network
affects the entire network), and tracing of a fault in a large network can
be extremely difficult.
child process
In multitasking operating systems, a subprocess created by a parent
process that is currently running on the system.
