Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) — Question 239

Which method of account authentication does OAuth 2.0 use within REST APIs?

Answer options

• A. username/role combination
• B. access tokens
• C. cookie authentication
• D. basic signature workflow

Correct answer: B

Explanation

OAuth 2.0 employs access tokens as a method of account authentication to grant access to resources. The other options, such as username/role combinations and cookie authentication, do not align with the OAuth 2.0 framework, while the basic signature workflow is not a recognized method used within this context.
