Exam 350-401 topic 1 question 876 discussion

The two mechanisms used with OAuth 2.0 for enhanced validation are: A. Authorization OAuth 2.0 is primarily an authorization framework that allows applications to request limited access to user resources on behalf of a user. It ensures that the client has the right to perform actions on behalf of the resource owner. D. Authentication Although OAuth 2.0 is not directly an authentication protocol, it is often used in combination with other protocols (like OpenID Connect) to validate the identity of the user in the process of authorizing access. Why other options are incorrect: B. Custom headers: While headers may be part of the OAuth process (e.g., passing tokens in HTTP headers), they are not a core mechanism of OAuth validation itself. C. Request management: OAuth does not manage requests directly; it deals with access tokens and scopes for authorization. E. Accounting: This term is typically related to tracking usage or resource consumption, which is not directly part of OAuth 2.0's validation processes.

1. OAuth 2.0 is primarily an authorization framework. 2. OAuth 2.0 is not primarily an authentication protocol (OpenID Connect adds authentication on top of OAuth 2.0)

A and D correct

Authorization: OAuth 2.0 is primarily used for authorization purposes, allowing applications to access resources on behalf of a user after the user grants permission. Authentication: OAuth 2.0 also involves authentication to verify the identity of the user or application accessing the resources. This ensures the security and integrity of the authorization process.

A & D are right, the other options, custom headers (B), request management (C), and accounting (E), are not directly related to OAuth 2.0 mechanisms for enhanced validation. OAuth 2.0 primarily focuses on authorization and relies on external authentication mechanisms.

OAuth 2.0 itself handles Authorization and manages Client Requests, so if you interpret the question to mean, "What mechanisms does OAuth 2.0 provide?", A & C seems correct. However in typically ambiguous Cisco fashion, the question asks which mechanisms are used *with* OAuth 2.0, and Authentication is very often paired with it. So A & D is just as viable depending on how you interpret the question.

A. Authorization (Correct): OAuth 2.0 is primarily used for authorization, allowing a third-party application to access resources on behalf of the resource owner after the resource owner grants permission. The authorization process is a fundamental part of OAuth 2.0. D. Authentication (Correct): While OAuth 2.0 itself is not an authentication protocol, it is often used in conjunction with authentication mechanisms such as OpenID Connect. OpenID Connect is built on top of OAuth 2.0 and provides authentication capabilities. So, authentication is an important aspect when OAuth is used in certain contexts.

A & C I Believe OAuth 2.0 is an authorization protocol and NOT an authentication protocol. As such, it is designed primarily as a means of granting access to a set of resources, for example, remote APIs or user data.
