A network administrator is troubleshooting a production network with poor visibility.

Reports:

  • !Log entries appear out of chronological order — timestamps are inconsistent
  • !No centralized logging visibility across all devices
  • !Network devices are not being monitored for performance or alerts
  • !Device-to-device connections are unclear — no discovery protocol output

Analyze management protocols to identify what is missing, understand how each protocol works, and improve network visibility.
