EMC Proven Professional – Technology Architect — Question 7

What is an OpenID mechanism?

Answer options

• A. An open standard for authentication in which a service provider uses authentication services from an identity provider
• B. An open authorization mechanism that allows a client to access protected resources from a resource server on behalf of a resource owner
• C. A network authentication protocol that provides strong authentication for client/server applications by using secret-key cryptography
• D. A mechanism that examines data packets traversing a network and compares them to a set of filtering rules

Correct answer: A

Explanation

The correct answer is A because OpenID is specifically designed as an open standard for authentication, allowing service providers to use identity providers for user authentication. Options B, C, and D describe different mechanisms related to authorization, authentication protocols, and network filtering, which do not accurately represent OpenID's purpose.
