Question: A technician is troubleshooting a network issue affecting multiple remote terminal units (RTUs) communicating with a central SCADA server. Several RTUs are intermittently losing connection for short periods. They are all connected via an industrial Ethernet network. Which of the following is the MOST effective first step to diagnose the intermittent disconnections?
Answer options:
- Replacing all communication cables in the network. ✅ Checking network switch logs for port errors or excessive collisions.
- Rebooting the SCADA server and all RTUs simultaneously.
- Rewriting the RTU firmware to improve network stability.
Correct answer: Checking network switch logs for port errors or excessive collisions.
Explanation: Checking network switch logs for errors or collisions provides valuable diagnostic information about the health of the network infrastructure, often pointing to specific faulty ports or congestion that can cause intermittent issues. Replacing all cables, rebooting everything, or rewriting firmware are much more drastic and less targeted initial steps.
