   A network monitoring platform must notify a ticketing system the moment a link-down event is detected. The ticketing system's API is only reachable from the corporate network, and the monitoring platform is cloud-hosted. The team wants to avoid constant polling and needs near-real-time alerts. Which approach should the team implement?

   • ASchedule a nightly batch job to export link-down events and email them to the ticketing system.
   • BUse a syslog server to forward link-down messages to the ticketing system via UDP port 514.
   • CHave the ticketing system poll the monitoring platform's REST API every 30 seconds for new link-down events.
   • DConfigure the monitoring platform to send an HTTP POST to the ticketing system's webhook URL whenever a link-down event occurs.

   A network admin wants to automate the creation of a trouble ticket whenever a critical event is detected on a network device. The device supports webhooks and the ticketing system has an API that accepts incoming webhooks. What is the most efficient way to achieve this?

   • AUse a script that periodically checks the device's syslog and creates tickets for critical messages.
   • BPoll the device for critical events every 5 minutes and then use the ticketing API to create a ticket.
   • CConfigure the device to send a webhook directly to the ticketing system's webhook endpoint when a critical event occurs.
   • DHave the device send an email to the admin, who then manually creates a ticket.

   A small startup is building an IoT monitoring system. They have a limited number of devices that send data infrequently, but they need to react quickly when a device sends an alert. They are deciding between using webhooks or polling the device API. Which approach is more appropriate and why?

   • AUse webhooks only if the devices support HTTPS, otherwise polling is required.
   • BUse polling because webhooks cannot be used with IoT devices.
   • CUse polling because it is simpler to implement and does not require registering a callback URL.
   • DUse webhooks because they provide push-based notifications, allowing immediate reaction to alerts without constant polling.

   A network operations center (NOC) wants to receive real-time alerts when a specific router's interface goes down. The router supports webhooks. The NOC team needs to integrate these alerts into their existing chat application. What is the most appropriate way to achieve this?

   • APoll the router's interface status every minute and post a message to the chat application when a change is detected.
   • BHave the router send an email to the NOC team whenever the interface goes down.
   • CConfigure the router to send a webhook to the chat application's incoming webhook URL when the interface state changes.
   • DUse an SNMP trap receiver that forwards alerts to the chat application via email.
