CompTIA Cloud+ (CV0-003) — Question 171

A company uses multiple SaaS-based cloud applications. All the applications require authentication upon access. An administrator has been asked to address this issue and enhance security. Which of the following technologies would be the BEST solution?

Answer options

• A. Single sign-on
• B. Certificate authentication
• C. Federation
• D. Multifactor authentication

Correct answer: D

Explanation

Multifactor authentication (MFA) is the most effective solution as it requires users to provide multiple forms of verification before gaining access, significantly enhancing security. Single sign-on simplifies access but does not add an extra layer of security. Certificate authentication and federation also improve security, but they do not provide the same level of user verification as MFA.
