QuestionQ524

Understanding and Using APIs

A network engineer sends several API calls to Cisco Prime to obtain a list of all devices. Each received response contains only a subset of the devices. The engineer observes that some API calls return HTTP code 429 rather than 200. Why were some devices omitted from the response?

  • A The API applied an offset that was indicated in the request.
  • B The API failed to identify how many items to retrieve.
  • C The API timed out the request.
  • D The API rate limited the request.
Explanation

HTTP 429 indicates that the API request rate limit was exceeded; requests beyond that limit are rejected or throttled rather than returning a normal successful response.
