EMC Proven Professional – Technology Architect — Question 19

Which entities are involved in the OAuth mechanism?

Answer options

• A. Resource owner, resource server, client, authorization server
• B. Resource owner, resource server, client, application server
• C. Resource client, resource server, owner, authentication server
• D. Resource client, resource server, owner, application server

Correct answer: A

Explanation

The correct answer, A, enumerates the four key entities in the OAuth mechanism: the resource owner, resource server, client, and authorization server. Options B, C, and D incorrectly substitute either the authorization server or the client with other terms that do not accurately represent the OAuth framework, thus making them invalid.
