SANS SEC 275 Questions with verified answers
.deb, .rpm Ans✓✓✓ File endings for packages
"AND" (pg. 66) Ans✓✓✓ Checks if two inputs are both true
-Considered connective, an AND connective is called a conjunction
"NAND" Ans✓✓✓ And circuit followed by a NOT circuit
-NAND is connective and is known as an alternative denial
"NOR" Ans✓✓✓ Or circuit followed by NOT circuit
-NOR is connective and is known as a joint denial
"NOT" Ans✓✓✓ Only takes one input - inverts whatever input it recieves, so true
becomes false and false becomes true
-NOT is represented by !
-NOT is connective and is a negation
"OR" Ans✓✓✓ Checks if at least one of the inputs is true
-OR is connective, known as a disjunction
"XOR" Ans✓✓✓ Exclusive OR, checks if only one side of the other is true, but not
both. If only one input is true, then the output is true.
-XOR is exclusive, meaning it doesn't like both inputs being true. XOR is
connective and known as an exclusive disjunction
,0b11001 (binary) Ans✓✓✓ 0d25 (denary)
APFS Ans✓✓✓ Apple File System. Default on most Mac systems
Apt-get (pg. 203) Ans✓✓✓ Linux command for installing or updating a program
using the advanced packaging tool.
ARP (pg 316) Ans✓✓✓ Address Resolution Protocol. Resolves IP addresses to
MAC addresses. ARP poisoning attacks can redirect traffic through an attacker's
system by sending false MAC address updates. VLAN segregation helps prevent
the scope of ARP poisoning attacks within a network.
ASCII Ans✓✓✓ a code for representing English characters as numbers, with each
letter assigned a number from 0 to 127
Authoritative name servers Ans✓✓✓ Responsible for the last two parts of any
domain name which is the resolution at which a single organization may be
responsible for DNS lookups.
-Controls mapping between IP adress and domain name
Base64 (pg. 59) Ans✓✓✓ An encoding scheme that converts binary data (e.g.
image, audio, etc.) into ASCII string.
Benefit of RAM Ans✓✓✓ Speed
Benefits of virtualization Ans✓✓✓ pg. 108-109
, Best way to configure networking on a linux system is... (pg 122) Ans✓✓✓ Do it
from the command line
BIOS Ans✓✓✓ Basic Input/Output System
-Stores on motherboard
-First program to be loaded
-Stores on the RAM of the motherboard
Bit (pg. 44) Ans✓✓✓ A contraction of "Binary Digit". A bit is the single unit of
information in a computer, typically represented as a 0 or 1.
1 byte = 8 bits
1 kilobyte (kB) = 1,000 bytes
1 megabyte (MB) = 1,000 kilobytes
1 gigabyte (GB) = 1,000 megabytes
1 terabye (TB) = 1,000 gigabytes
Booatloader (pg. 101) Ans✓✓✓ program that is loaded by the BIOS when a
computer is first on an is responsible for loading the OS
Boolean statement Ans✓✓✓ Statements that can be only true or false, known as
a proposition
Buses Ans✓✓✓ Collection of wires that carry signals between various
components of the computer system
