An automation script is receiving HTTP 500 Internal Server Error responses from a Cisco DNA Center API when attempting to deploy a template. The request appears correct according to the documentation. What is the most appropriate troubleshooting step?

Regenerate the API token and retry

Inspect the API server logs and the response body for error details

Modify the request body to use different field names

Change the endpoint URL to a different version

A developer is integrating with a Cisco Webex API that uses rate limiting. The API documentation states that the rate limit is 10 requests per second per token. The developer's script sends 20 requests in quick succession and receives HTTP 429 Too Many Requests for some of them. The developer needs to ensure all requests succeed without violating the rate limit. What is the most appropriate approach?

Implement exponential backoff and retry logic that respects the Retry-After header

Increase the number of API tokens to distribute the requests

Send all requests in parallel to complete faster

Ignore the 429 responses and assume the requests succeeded

An engineer is using a REST API to update a network device configuration. The API documentation specifies that the endpoint requires a Content-Type header of application/json and a body containing the full configuration object. The engineer sends a PUT request with the correct body but receives HTTP 415 Unsupported Media Type. What is the most likely cause?

The server is temporarily overloaded

The Content-Type header is set to text/plain instead of application/json

The request body is missing a required field

A Python script uses the requests library to call a Cisco DNA Center API. The script receives a 401 Unauthorized response. The script previously worked with the same credentials. What is the most likely cause?

The request body is missing a required field.

The script is using the wrong HTTP method.

The API endpoint has been deprecated.

The API token has expired and needs to be refreshed.

An engineer is troubleshooting a failed API call to a Cisco Intersight API. The request is a POST to /api/v1/compute/RackUnit with a JSON body. The response is HTTP 415 Unsupported Media Type. The engineer checks the request and sees that the Content-Type header is set to application/json. What is the most likely cause?

The server is temporarily overloaded

The request body is not valid JSON, even though the Content-Type header is correct
