Developing Applications Using Cisco Core Platforms and APIs (DEVCOR) — Question 189

Which OAuth mechanism enables clients to continue to have an active access token without further interaction from the user?

Answer options

• A. refresh grant
• B. JWT
• C. password grant
• D. preshared key

Correct answer: A

Explanation

The refresh grant allows a client to obtain a new access token using a refresh token, thereby maintaining access without requiring the user to log in again. JWT (JSON Web Token) is a token format, not a mechanism for obtaining tokens. The password grant requires user credentials for each token, while preshared key is not relevant to OAuth token management.
