Security Fundamentals — Question 4

Which password attack uses all possible alpha numeric combinations?

Answer options

• A. Social engineering
• B. Brute force attack
• C. Dictionary attack
• D. Rainbow table attack

Correct answer: C

Explanation

The correct answer is B, as a brute force attack systematically tries all possible combinations of characters. Social engineering relies on manipulating individuals to disclose passwords, while a dictionary attack uses a pre-defined list of common passwords. A rainbow table attack utilizes precomputed hashes to crack passwords more efficiently, but does not cover all alphanumeric combinations.
