Which feature provides network monitoring using NetFlow?

The feature that provides network monitoring using NetFlow is the Distributed Virtual Switch. This technology is specifically designed to facilitate advanced networking capabilities within a VMware vSphere environment, allowing for better management and monitoring of virtual networks across multiple hosts.

The Distributed Virtual Switch provides centralized management of virtual networking, which includes the ability to implement NetFlow for traffic analysis and monitoring. With NetFlow, network administrators can gain insights into network traffic patterns, identify potential bottlenecks, and enhance overall network performance by analyzing data at a granular level.

While Standard Switches can be used for networking in a VMware environment, they do not support advanced features like NetFlow monitoring. Physical Switches are part of the hardware layer and do not directly integrate with the virtualized components in the same way as a Distributed Virtual Switch. VM Networks refer to the logical networks mapped to virtual machines but do not encompass the monitoring capabilities provided by NetFlow.
