CompTIA Network+ (N10-009) — Question 265

After providing a username and password, a user must input a passcode from a phone application. Which of the following authentication technologies is used in this example?

Answer options

• A. SSO
• B. LDAP
• C. MFA
• D. SAML

Correct answer: C

Explanation

The correct answer is C, MFA (Multi-Factor Authentication), which requires users to provide multiple forms of verification before they can access an account. The other options, such as SSO (Single Sign-On), LDAP (Lightweight Directory Access Protocol), and SAML (Security Assertion Markup Language), do not involve the use of a secondary code from a mobile application, which is essential for MFA.
