Packet capture
Answers
D.
Packet capture
Suggested answer: C

Explanation:

Flow data is a summary of network traffic that can be used to monitor and analyze network performance, utilization, and security. Flow data can provide information such as source and destination IP addresses, ports, protocols, bytes, packets, and timestamps. Flow data can be collected using protocols such as NetFlow, sFlow, or IPFIX. Flow data can help identify the source of network saturation without requiring a full packet capture, which would be impractical on a 40Gb connection with a 10Gb server.
