CompTIA ITF+ (FC0-U61) — Question 198

When users access a company’s website from home, they are prompted to log in with a username and password. However, when in the office they are not prompted to log in and instead are able to access the website directly. Which of the following is this the BEST example of?

Answer options

• A. Multifactor authentication
• B. Non-repudiation
• C. Hardware token
• D. Single sign-on

Correct answer: D

Explanation

The correct answer is D, Single sign-on, because it allows users to access multiple applications with one set of credentials, particularly in a trusted environment like the office. The other options do not apply to this scenario: Multifactor authentication involves multiple forms of verification, non-repudiation ensures that actions cannot be denied, and a hardware token is a physical device for authentication.
