Correct Answer: B
Bandwidth usage is the amount of data transferred over a network connection in a given time period. It is an indicator of how much traffic is flowing through a network device or link. Peak network traffic is the highest level of bandwidth usage that occurs during a specific time interval, such as an hour, a day, or a week.
Monitoring peak network traffic can help you identify potential bottlenecks, plan for capacity, and optimize network performance. NPM can monitor bandwidth usage on nodes and interfaces using SNMP, WMI, or NetFlow protocols. You can view bandwidth usage charts and reports in the web console, as well as set alerts and thresholds for bandwidth utilization.
