WGU D334 – INTRODUCTION TO CRYPTOGRAPHY
EXAM QUESTIOS AND CORRECT ANSWERS | LATEST
UPDATE 2026/2027 | ALREADY GRADED A+ | BRAND
NEW | 100% PASS | WGU


1. What is the primary purpose of cryptography?
A. To store data securely
B. To protect data confidentiality, integrity, and authenticity
C. To back up information
D. To manage network traffic
Rationale: Cryptography is used to secure communication and protect
data by ensuring confidentiality, integrity, and authenticity.

2. Which of the following is a symmetric encryption algorithm?
A. AES
B. RSA
C. ECC
D. Diffie-Hellman
Rationale: AES (Advanced Encryption Standard) is a symmetric
encryption algorithm, meaning it uses the same key for both
encryption and decryption.

3. What is the main disadvantage of symmetric encryption?
A. It is slower than asymmetric encryption

B. Key distribution is difficult
C. It provides no confidentiality
D. It uses large key sizes

,Rationale: Symmetric encryption requires both parties to have the
same key, making secure key distribution a challenge.



5. What is a digital signature used for?
A. Encrypting messages
B. Ensuring message authenticity and integrity
C. Speeding up encryption
D. Preventing eavesdropping
Rationale: Digital signatures verify the sender's identity and ensure
the message has not been altered.

6. Which type of cryptography is primarily used for creating digital
signatures?
A. Symmetric
B. Asymmetric
C. Block cipher
D. Stream cipher
Rationale: Digital signatures rely on asymmetric cryptography,
where the sender
signs with a private key and the recipient verifies with the sender’s
public key.
