CompTIA A+ Core 2 (220-1102) — Question 413

A technician needs to strengthen security controls against brute-force attacks. Which of the following options best meets this requirement?

Answer options

• A. Multifactor authentication
• B. Encryption
• C. Increased password complexity
• D. Secure password vault

Correct answer: C

Explanation

Increased password complexity is the best option as it makes it significantly harder for attackers to successfully guess passwords during a brute-force attack. While multifactor authentication adds an additional layer of security, it does not directly address the strength of the passwords themselves. Encryption and secure password vaults do not specifically mitigate brute-force attacks on password guessing.
