A script calls the Cisco Webex API to list all messages in a room. The API returns HTTP 404 Not Found because the room was deleted. The script's current logic retries the request three times with a 10-second delay. What is the most appropriate classification of this error?

Recoverable, because the room may be recreated automatically

Recoverable, because the 404 may be a transient server error

Unrecoverable, because the room no longer exists and retrying will not recreate it

Unrecoverable, but the script should retry once to confirm

A monitoring script calls the Cisco Meraki API every 5 minutes to check the status of a network. The API returns HTTP 429 Too Many Requests with a Retry-After header of 60 seconds. The script's current logic treats all non-2xx responses as unrecoverable and terminates. What is the most appropriate change?

Treat the 429 as recoverable and retry after the Retry-After delay

Increase the monitoring interval to 10 minutes to avoid the 429

Ignore the 429 and continue with the next monitoring cycle

Keep the current logic because 429 is a permanent error

A developer is writing a function that calls the Cisco Webex API to delete a meeting. The API returns HTTP 409 Conflict because the meeting is currently in progress. The developer wants to handle this specific error differently from other errors. Which control flow approach is most appropriate?

Use a try/except block that catches the HTTPError and checks the status code

Use a pass statement to ignore the 409 and continue

Use a return statement to exit the function without any error handling

Use a while loop that retries the delete until the meeting ends
