CompTIA Network+ (N10-009) — Question 391

A company uses a solution to rotate the password that engineers use to connect to critical systems. Which of the following best describes this solution?

Answer options

• A. Network access control
• B. TACACS+
• C. Key management
• D. Multifactor authentication

Correct answer: C

Explanation

The correct answer is C, Key management, as it refers to the administration of cryptographic keys and passwords, including their rotation. Options A, B, and D do not specifically address the rotation of passwords; Network access control is about managing access, TACACS+ is a protocol for authentication, and multifactor authentication involves using multiple methods to verify identity.
