A network administrator received reports that a 40Gb connection is saturated. The only server the administrator can use for data collection in that location has a 10Gb connection to the network. Which of the following is the best method to use on the server to determine the source of the saturation?
Correct Answer: C
This is because flow data is a method of collecting and analyzing information about the traffic flows on a network. Flow data can provide details such as the source and destination IP addresses, ports, protocols, and bytes transferred for each flow. Flow data can help identify the source of the saturation by showing which hosts and applications are generating or consuming the most bandwidth. Flow data can be collected using protocols such as NetFlow, IPFIX, or sFlow. The source of this answer is the Cisco ENCOR v1.1 course, module 10, lesson 10.1: Implementing NetFlow and IPFIX.
