SNMP, NetFlow, syslog, Wireshark, latency, jitter, packet loss, throughput,
bandwidth, QoS, troubleshooting methodologies, topology mapping, device
health, interface errors, CPU/memory utilization, link utilization, alerting
thresholds, and reporting. Each question has four options with one correct answer
marked with ✅. Correct answers are intentionally mixed (not all A, B, C, or D).
