CompTIA CASP+ (CAS-004) — Question 563

A software house is developing a new application. The application has the following requirements:
✑ Reduce the number of credential requests as much as possible
✑ Integrate with social networks
✑ Authenticate users
Which of the following is the BEST federation method to use for the application?

Answer options

• A. WS-Federation
• B. OpenID
• C. OAuth
• D. SAML

Correct answer: B

Explanation

OpenID is the best choice because it allows users to authenticate via their existing social network accounts, thereby reducing the need for multiple credential requests. WS-Federation and SAML are more complex and suited for enterprise environments, while OAuth is primarily used for authorization, not authentication.
