A network operations center (NOC) wants to receive immediate notifications when a critical router interface goes down, but they do not want to be paged for minor issues. What is the best approach?

Set up NetFlow and alert on high traffic

Use a packet sniffer to detect link failures

Configure SNMP traps with severity-based alerting rules

Enable syslog and monitor all messages

A network administrator is troubleshooting a security incident. The administrator needs to determine when a specific user's workstation last connected to the network and which switch port it used. Which log source should be examined first?

Switch authentication and port logs

During traffic analysis, an administrator notices a sudden spike in outbound traffic from a single workstation. What is the most likely concern?

A possible security compromise or malware activity

A hardware failure in the switch

A network administrator is setting up monitoring for a new application that will be deployed across the WAN. The administrator wants to establish a performance baseline to detect future anomalies. What is the most appropriate first step?

Configure alerts based on vendor-recommended thresholds

Immediately set thresholds based on the application's maximum capacity

Collect performance data during normal operation over a representative period

Enable NetFlow on all routers and switches
