Using APIs

Refer to the exhibits. An application has been developed to perform multiple API calls. The calls are performed on the infrastructure devices. Information-transfer delays occur when the application runs. What are two reasons for this issue?

Choose two
  • A The list devices API call is failing and does not return a result.
  • B The requests are being rate limited to prevent multiple calls causing the excessive load.
  • C One of the API calls takes roughly three times as long to complete.
  • D Listing devices takes longer than usual due to high network latency.
  • E The list devices API call is inefficient and should be refactored.
Explanation

The authentication call completes in 5 seconds, whereas the device-list operation takes 13.25 seconds, or roughly three times longer. The device-list API is called within a list comprehension, which repeats a full device-list retrieval for every iterated device rather than retrieving the list once; this is inefficient and should be refactored. Cisco’s API defines the device-list operation as returning the list of network devices, so repeated calls are unnecessary for obtaining that same list.
