WGU D334 ACTUAL EXAM PAPER 2026
COMPLETE QUESTIONS AND SOLUTIONS
GRADED A+
◉ variable; fixed
Answer: Hashing involves taking a _____ length input and producing a
_____ length output (message digest).
A. fixed; fixed
B. variable; fixed
C. fixed; variable
◉ 160
Answer: The hash value in bits for SHA-1 is ____.
A. 128
B. 160
C. 256
◉ 128
Answer: The hash value in bits for MD4 is ____.
,A. 128
B. 160
C. 256
◉ Transport
Answer: IPSec ______ mode involves "end-to-end" encryption; i.e. data
remains encrypted from the time it leaves a sender's device to the
time it arrives at the receiver's device.
A. Tunnel
B. Transport
C. Trusted
◉ Tunnel
Answer: IPSec ______ mode involves encryption from gateway to
gateway, i.e. just through the public network space.
A. Tunnel
B. Transport
C. Trusted
◉ Tunnel
,Remember, with tunnel mode, encryption does not happen until just
before it leaves the local network. Traffic likely remains unencrypted
between the end user device and the local network boundary.
Answer: A security analyst on a local network using monitoring tools
is likely to only be able to read contents of traffic encrypted using
IPSec ______ mode.
A. Tunnel
B. Transport
C. Trusted
◉ Chaskey
Answer: _____ is a lightweight cryptography method for signing
messages (MAC). It boasts a relatively undemanding hardware
implementation (only ~3,333 gates required at 1MHz clock rate)
making it suitable for IoT implementation.
◉ 128
Answer: Chaskey has a key size of _____ bits.
A. 256
B. 128
C. 80
◉ salt
, Answer: A weakness of one-way hashing is that the same piece of
plaintext will result in the same ciphertext unless _____ is applied.
A. Salt
B. Ash
C. Ether
◉ 40
Answer: The minimum recommended key size to use with RC4 is
_____ bits.
A. 40
B. 20
C. 64
◉ 2048
Answer: RC4 is a symmetric stream cipher with a variable key size
up to a max of _____ bits.
A. 256
B. 2048
C. 1024
◉ Data Encryption Standard (DES)
Answer: _____ has a block size of 64 bits, key size of 56 bits, and 16
rounds of substitution & transposition.
