CompTIA A+ Core 2 (220-1002) — Question 113

Joe, an end user, has been prompted to provide his username and password to access the payroll system.
Which of the following authentication methods is being requested?

Answer options

• A. Single-factor
• B. Multifactor
• C. RADIUS
• D. TACACS

Correct answer: A

Explanation

The correct answer is A, Single-factor, because only one method of authentication, which is the username and password, is being used. Multifactor authentication would require additional methods beyond just a username and password, while RADIUS and TACACS are protocols for managing authentication but do not describe the type of authentication method being used.
