CompTIA PenTest+ (PT0-001) — Question 121

Which of the following BEST protects against a rainbow table attack?

Answer options

• A. Increased password complexity
• B. Symmetric encryption
• C. Cryptographic salting
• D. Hardened OS configurations

Correct answer: A

Explanation

The correct answer is A, as increased password complexity makes it harder for attackers to guess passwords, thereby reducing the effectiveness of rainbow tables. Options B and D do not specifically address the issues related to hashing and password storage, while C, although helpful, does not offer the same level of protection as increased complexity in passwords.
