Which feature of vSphere networking restricts the inbound and outbound network bandwidth of a group of virtual machines?

Differentiated Services Code Point (DSCP) is used for classifying and prioritizing network traffic (Quality of Service) but does not directly restrict the bandwidth of virtual machines.

NetFlow is a protocol designed for collecting and analyzing IP traffic statistics for monitoring purposes, not for enforcing bandwidth restrictions.

Traffic Shaping allows administrators to configure specific policies, including average bandwidth, peak bandwidth, and burst size, to restrict the network throughput for a port group or individual virtual machine, effectively managing its network resource consumption.

Port Mirroring (SPAN) is a feature that duplicates network traffic from one port to another for monitoring and analysis, it does not limit bandwidth.
