CompTIA Security+ (SY0-601) — Question 247

Audit logs indicate an administrative account that belongs to a security engineer has been locked out multiple times during the day. The security engineer has been on vacation for a few days. Which of the following attacks can the account lockout be attributed to?

Answer options

• A. Backdoor
• B. Brute-force
• C. Rootkit
• D. Trojan

Correct answer: B

Explanation

The correct answer is B, as a brute-force attack involves systematically attempting multiple passwords to gain access, which could lead to the account being locked out. The other options, such as a backdoor, rootkit, or Trojan, do not directly cause account lockouts in this manner.
