Which security feature does stateless authentication and authorization use for REST API calls?

Answer options

• A. OAuth 2 tokens
• B. API keys
• C. SSL/TLS certificate encryption
• D. cookie-based session authentication

Correct answer: A

Explanation

The correct answer is A, as stateless authentication typically employs OAuth 2 tokens to manage user sessions without server-side storage. Options B and D represent alternative methods that involve stateful sessions or different types of credentials, while C refers to encryption protocols that secure data transmission but do not directly relate to authentication methods.
