Answer: A

Explanation:

NetFlow is a network protocol developed by Cisco for collecting IP traffic information and monitoring network traffic. It collects metadata of the IP traffic flowing across networking devices like routers and switches. On the other hand, Traffic mirroring involves capturing all the data packets that flow through a particular point in the network to analyze or inspect them later.
