CRYPTOGRAPHY FINAL EXAM REVIEW WITH 250 REAL
EXAM QUESTIONS AND CORRECT VERIFIED ANSWERS/
ALREADY GRADED A+ (BRAND NEW!!)
Q1. What is the primary goal of cryptography?
A) Data compression
B) Data confidentiality
C) Data deletion
D) Data duplication
Correct Answer: B) Data confidentiality
Rationale: Cryptography primarily ensures that data remains
private and inaccessible to unauthorized parties, though it also
supports integrity, authentication, and non-repudiation.
1
,Q2. Which of the following is NOT a basic goal of
cryptography?
A) Confidentiality
B) Integrity
C) Authentication
D) Obfuscation
Correct Answer: D) Obfuscation
Rationale: The four core goals are confidentiality, integrity,
authentication, and non-repudiation. Obfuscation is not a
standard cryptographic goal.
Q3. A cipher that uses the same key for encryption and
decryption is called:
A) Asymmetric
B) Symmetric
2
,C) Hash function
D) One-time pad
Correct Answer: B) Symmetric
Rationale: Symmetric-key algorithms use a single shared secret
key for both encryption and decryption.
Q4. Which algorithm is an example of a stream cipher?
A) AES
B) RSA
C) RC4
D) 3DES
Correct Answer: C) RC4
Rationale: RC4 is a stream cipher, encrypting data one byte at
a time, while AES and 3DES are block ciphers.
3
, Q5. What is the primary weakness of symmetric encryption?
A) Slow speed
B) Key distribution problem
C) Weak security
D) Large key sizes
Correct Answer: B) Key distribution problem
Rationale: Both parties must share the same secret key securely
before communication, which is challenging at scale.
Q6. Which encryption standard succeeded DES?
A) 3DES
B) AES
C) Blowfish
D) Twofish
