WGU D431 UPDATED EVALUATION TEST QUESTIONS AND
SOLUTIONS GUARANTEE A+
✔✔Post Office Protocol version 3 (POP3) - ✔✔A protocol used to receive email that
works on port 110.
✔✔Power-on self-test (POST) - ✔✔A brief hardware test the BIOS performs upon boot-
up.
✔✔Probative value - ✔✔The value of evidence in helping determine the facts in a case.
✔✔Protected computer - ✔✔Any computer at a financial institution of any kind or a
government agency.
✔✔Rainbow table - ✔✔Type of password crackers that work with precalculated hashes
off all passwords available within a certain character space.
✔✔Real evidence - ✔✔Physical objects that can be touched, held, or directly observed,
such as a laptop with a suspect's fingerprints on it or a handwritten note.
✔✔Recover time objective (RTO) - ✔✔The time that the system is expected to be back
up. This must be less than MTD.
✔✔Recovery point objective (RPO) - ✔✔The amount of work that might need to be
redone, or data lost.
✔✔Routing table - ✔✔A table used with routers to track what IP addresses are
connected to ports on the router.
✔✔Rules of evidence - ✔✔Rules that govern whether, when, how, and why proof of a
legal case can be placed before a judge or jury.
✔✔Scrubber - ✔✔Software that cleans unallocated space. Also called a sweeper.
✔✔Simple Mail Transfer Protocol (SMTP) - ✔✔A protocol used to send email that works
on port 25.
✔✔Slack space - ✔✔The unused space between the logical end of file and the physical
end of file. It is also called file slack.
✔✔Slurred image - ✔✔The result of acquiring a file as it is being updated.
✔✔Sniffer - ✔✔Computer software or hardware that can intercept and log traffic passing
over a digital network.
, ✔✔Social engineering - ✔✔Nontechnical means of obtaining information you would not
normally have access to.
✔✔Software forensics - ✔✔The process of examining malicious computer code.
✔✔Spoofing - ✔✔The act of making an email message appear to come from someone
or someplace other than the real sender or location.
✔✔Stack (S) - ✔✔Memory is allocated based on the last-in, first-out (LIFO) principle.
✔✔Steganalysis - ✔✔The determination of whether a file or communication hides other
information.
✔✔Steganography - ✔✔The art and science of writing hidden messages.
✔✔Steganophony - ✔✔The use of steganography with sound files.
✔✔Stream cipher - ✔✔A form of cryptography that encrypts the data as a stream, one
bit at a time.
✔✔Subnetting - ✔✔Dividing a network into smaller portions.
✔✔Subscriber Identity Module (SIM) - ✔✔A card that identifies a phone with a user and
a number.
✔✔Substitution - ✔✔In cryptography, the method of changing some part of the plaintext
for some matching part of ciphertext.
✔✔Swap file - ✔✔A virtual memory extension of RAM that can be temporary or
permanent.
✔✔Sweeper - ✔✔A kind of software that cleans unallocated space. Also called a
scrubber.
✔✔Symmetric cryptography - ✔✔Those methods where the same key is used to
encrypt and decrypt the plaintext.
✔✔Temporary data - ✔✔Data that an operating system creates and overwrites without
the computer user taking a direct action to save this data.
✔✔Test system - ✔✔A functional system compatible with the hard drive from which
someone is trying to recover data.
