   An engineer is automating a workflow that requires retrieving device configuration from DNA Center and posting a summary to a Webex room. The engineer has a DNA Center session and a Webex bot token. The script must handle the case where the DNA Center session expires during the workflow. Which approach is best?

   • ACreate a new DNA Center session before every API call.
   • BIgnore authentication errors and continue with the Webex message.
   • CWrap the entire workflow in a try/except block and re-authenticate to DNA Center if an authentication error occurs, then retry the failed operation.
   • DUse a very long timeout on the DNA Center session to prevent expiry.

   A developer is using the Meraki SDK to update multiple SSIDs across many networks. The script occasionally fails with a rate limit error (HTTP 429). The developer wants to make the script more robust without overcomplicating it. Which approach is the most effective?

   • AUse the SDK's built-in retry feature, which automatically retries all failed requests.
   • BCatch the 429 exception and retry the request after a short delay, with a maximum number of retries.
   • CIncrease the SDK's timeout parameter to 60 seconds.
   • DIgnore the 429 error and continue with the next SSID.

   A developer is using the Cisco Meraki SDK to update the MX firewall rules for a large number of networks. The script must handle rate limiting and ensure that each update is confirmed before proceeding to the next network. The developer has noticed that the SDK's built-in retry mechanism is not sufficient because the rate limit is very low. Which approach best handles this situation?

   • AUse concurrent threads to send updates in parallel, reducing the overall time.
   • BIgnore the rate limit and rely on the SDK to handle errors.
   • CIncrease the SDK's retry count and timeout settings to allow more attempts.
   • DImplement a custom retry loop that waits for the Retry-After header and checks the response status after each attempt.

   An engineer is writing a script that uses the Cisco DNA Center SDK to automate network changes. The script will be run by a CI/CD pipeline. The engineer wants to ensure that the script fails fast if the DNA Center credentials are invalid, rather than waiting for a timeout. Which approach is best?

   • ACall a simple API like 'devices.getDeviceList' immediately after creating the DNACenterAPI object to validate the credentials.
   • BUse a try/except block around the entire script and catch all exceptions at the end.
   • CSet the 'timeout' parameter to a low value in the DNACenterAPI constructor.
   • DRely on the SDK to automatically retry authentication failures.
