   A network administrator set up a webhook to send client disconnect events to a custom analytics platform. The endpoint occasionally returns HTTP 500 errors during peak hours. The administrator notices that some events are missing from the analytics platform. What is the most likely reason for the missing events, and what should the administrator do?

   • AThe webhook is misconfigured because it uses HTTP instead of HTTPS. The administrator should change the URL to HTTPS.
   • BThe events are being filtered out because the webhook topic is set to 'Alarm Events' instead of 'Client Events'. The administrator should change the topic.
   • CMist retries failed deliveries for a limited time; if the endpoint remains unavailable, events are dropped. The administrator should make the endpoint more reliable.
   • DMist does not retry webhook deliveries, so any failure results in immediate loss. The administrator should implement a local queue.
