   A logistics company has deployed GPS trackers on its fleet. The trackers communicate via CoAP to a central server. The security team wants to detect if a tracker is sending data to an unauthorized endpoint. Which monitoring approach is most effective for this purpose?

   • AConfigure the central server to log all CoAP requests and alert on any destination IP not in the approved allowlist.
   • BMonitor the trackers' battery levels and alert if they drop faster than expected.
   • CCapture and store all raw packets from the trackers for forensic analysis after an incident.
   • DEnable SNMP traps on the trackers to report interface errors.
