A developer is building a dashboard that retrieves data from Cisco DNA Center. The API has a rate limit of 10 requests per second. The dashboard needs to display data for 500 devices, and each device requires a separate API call. The developer wants to minimize the total time to fetch all data while staying within the rate limit. Which approach should the developer use?

Make all 500 requests concurrently using asynchronous calls.

Increase the rate limit by requesting a higher quota from Cisco.

Make requests sequentially with a delay of 0.1 seconds between each request.

Use a concurrency limit of 10 and process the requests in batches, waiting for each batch to complete before starting the next.

Which of the following is an example of data transformation that might be performed before visualizing API data?

Adding a new user account to the dashboard application

Increasing the timeout value for API requests

Changing the API endpoint URL to point to a different server

Converting timestamps from Unix epoch to a human-readable date format
