GFACT Questions and Correct
Answers the Latest Update
/ qn
✓ Don't launch with a graphical user interface.
/i
✓ Don't try to run as administrator, run as a normal user instead (this won't matter
because of AlwaysInstallElevated).
/quiet
✓ Don't show the user any messages.
1024?!
✓ 1 kilobyte = 1024 bytes. IEC introduced KiB instead: 1 byte is 8 bits. 1 kibibyte (KiB)
is 1024 bytes. 1 mebibyte (MiB) is 1024 kibibytes. 1 gibibyte (GiB) is 1024 mebibytes.
1 tebibyte (TiB) is 1024 gibibytes.
Active Directory
✓ A system that allows the server to communicate with Windows desktops, allowing
the administrator to easily configure all the connected desktops from one location,
amongst other uses which we will cover in future modules. Active Directory allows
administrators to configure settings on Windows desktops that are connected to a
Windows server.
✓ Adding a new user is as simple as running: net user /add <username> <password>
This command will create a new user and set the password to what you specified.
You can do so much more when creating users this way, such as configuring account
expiry and setting times where the account can log on.
Add-ins
✓ Microsoft Word allows for third parties to write 'add-ins', which extend the
functionality of Microsoft Word.
Advanced Memory Forensics with Volatility
✓ Volatility is one of the most widely used memory forensics tools. Useful Volatility
commands: imageinfo - vol.py or volatility -f memdump.mem imageinfo
Aliases
✓ PowerShell comes with several aliases set up for common cmdlets. cat, cd, dir, ls, rm
Alternate Number Bases
✓ We are very used to counting in base 10, but other number bases like base 16 (hex)
or base 2 (binary) are incredibly useful in computing.
Alternative Search Engines
✓ No two search engines are the same. Alternative Search Engines - Google, Bing,
Yahoo, DuckDuckGo, archive.org
AlwaysInstall Elevated
✓ Some administrators will configure this so that users can install software on their
computers without administrator approval.
✓ Collecting stats and analysing interactions on a web server.
Anti Forensics
✓ Cyber criminals improve and modify their operational security (OpSec) in order to
avoid being caught. NotPetya is part of the Petya family of encrypting ransomware
that targets Microsoft Windows based systems.
APFS
✓ The Apple File System supports permissions and encryption, and duplicate files can
be stored without using additional space, with changes to one copy of a file being
saved as a delta (the difference between the old file and the new file) to lower space
requirements.
Application Layer
✓ An example of an application layer protocol is something like HTTP or FTP. HTTP
GET request is an application layer protocol because the web browser will form the
request necessary for displaying a page or submitting a form.
apropos
✓ The 'apropos' tool is used to search man pages for keywords, usually to find the
'appropriate' tool to use in a particular situation. The 'apropos' command is used to
find the 'appropriate' tool for a particular job.
apt-get
✓ The apt command is incredibly useful to rapidly find, install, or remove software. The
way 'apt' works is by having a list of 'sources'; these are servers which contain
information about available packages, download links and version information. 'apt
update' only updates the list of available packages.
✓ The 'argc' variable is an integer which contains the number of arguments passed to
the program when it was executed. The 'argv' array contains the data passed in.
Arithmetic Logic Unit (ALU)
✓ The Arithmetic Logic Unit is the part of the CPU responsible for performing
arithmetic and logical operations.
ARP
✓ The Address Resolution Protocol translates IP addresses to MAC addresses for
transmission purposes. ARP is only for the local network.
ARP Cache
✓ ARP (address resolution protocol) is a protocol used on local networks to map IP
addresses to MAC addresses. When a computer receives an ARP response, it saves
it into the ARP cache.
ARP Spoofing / Poisoning
✓ The flaw in the ARP protocol comes because, if an ARP response is sent to a
computer, it will store that value in its ARP cache even if it didn't make an ARP
request asking for a response.
Arrays
✓ In C, you have to specify the type of the array when you create it, and it can only
ever hold that type of data. You can't mix and match within the same array.
