CompTIA Network+ (N10-007) — Question 574

An administrator wants to implement an additional authentication factor to the remote SSH servers. Which of the following accomplishes this goal with the principle of `something you have`?

Answer options

• A. Certificate
• B. Pattern
• C. Password
• D. Fingerprint

Correct answer: A

Explanation

The correct answer is A, Certificate, as it represents a physical item that can be held, such as a smart card or hardware token, which is used for authentication. The other options, like Pattern, Password, and Fingerprint, do not fit the 'something you have' principle as they are either knowledge-based or biometric factors.
