Correct | Grade A (2026/2027)
This WGU D431 Digital Forensics in Cybersecurity (DQO1) course focuses on
identifying, collecting, preserving, and analyzing digital evidence, requiring
proficiency in forensic investigation methodologies, legal compliance, and network
security. The study guide cover topics like file systems, steganography, and anti-
forensics.
Exam Content & Key Areas (DQO1)
• Forensics Process: Identification, preservation, investigation, and analysis
of digital evidence.
• Legal & Ethics: Understanding laws like CALEA, HIPAA, and the Privacy
Protection Act.
• Mobile & Network: Data extraction from mobile devices and examining
network logs/traffic.
• Key Concepts: ASCII, anti-forensics, bit-level analysis, and asymmetric
cryptography.
• Investigation Steps: First-responder procedures, such as handling active
computers and securing evidence.
Quiz_________________?
American Standard Code for Information Interchange (ASCII) -
Answer
A set of codes defining all the various keystrokes you could make, including
letters, numbers, characters, and even the spacebar and return keys.
1
, Quiz_________________?
Anonymous remailing -
Answer
The process of sending an email message to an anonymizer. The anonymizer
strips identifying information from an email message before forwarding it with the
anonymous mailing computer's IP address.
Quiz_________________?
Anti-forensics -
Answer
The actions that perpetrators take to conceal their locations, activities, or
identities.
Quiz_________________?
Asymmetric cryptography -
Answer
Cryptography wherein two keys are used: one to encrypt the message and
another to decrypt it.
Quiz_________________?
Asynchronous transfer mode (ATM) -
Answer
2
, A high-speed connection technology that uses fixed-length, 53-byte packets called
calls.
Quiz_________________?
Authenticate -
Answer
To verify the identity of a person, or to verify evidence.
Quiz_________________?
Base transceiver station (BTS) -
Answer
The part of the cell network responsible for communications between the mobile
phone and the network switching system.
Quiz_________________?
Basic input/output system (BIOS) -
Answer
The basic instructions stored on a chip for booting up the computer.
Quiz_________________?
Bit-level information -
3
, Answer
Information at the level of actual 1s and 0s stored in memory or on the storage
device.
Quiz_________________?
Block cipher -
Answer
A form of cryptography that encrypts data in blocks; 64-bit blocks are quite
common, although some algorithms (like AES) use larger blocks.
Quiz_________________?
Bootstrap environment -
Answer
A special program, such as U-Boot or RedBoot, that is stored in a special section
of the flash memory.
Quiz_________________?
Brute-force attack -
Answer
An attack in which the attacker tries to decrypt a message by simply applying
every possible key in the keyspace.
