Correct answers: A, C
Explanation
When interpreting REST API responses from Cisco DNA Center, the HTTP status code provides insight into the success or failure of the API request. A '200 OK' indicates a successful request, and the payload in this case contains the requested network device details. Understanding the HTTP status codes and the structure of the JSON payload is essential for troubleshooting and utilizing the API effectively.
- A. Correct.
The HTTP status code '200' indicates a successful request and response cycle, meaning the server processed the request correctly.
- B. Incorrect.
A JSON payload with device details does not indicate an error. Error responses typically include status codes in the 4xx or 5xx range and may contain error descriptions.
- C. Correct.
The JSON payload in this scenario contains device details such as hostname, IP address, and platform type, as returned by Cisco DNA Center.
- D. Incorrect.
A status code of '200' does not indicate authentication failure. Authentication failures are usually indicated by a '401 Unauthorized' status code.
- E. Incorrect.
While Cisco DNA Center supports REST APIs, it does not strictly adhere to the RESTCONF data model. RESTCONF is a protocol used for network device configuration and management, whereas Cisco DNA Center uses a more general REST API approach.
