Implementing Cisco Collaboration Applications (CLICA) — Question 151

Which type of protocol is OAuth 2.0?

Answer options

• A. authorization
• B. accounting
• C. authentication
• D. single sign-on

Correct answer: A

Explanation

OAuth 2.0 is primarily an authorization protocol that allows third-party applications to obtain limited access to user accounts on an HTTP service. The other options, such as accounting and authentication, do not accurately describe OAuth 2.0's main function, and while it can be part of a single sign-on solution, that is not its primary purpose.
