Which resource management technique can be used to relieve a network bottleneck by a virtual machine with occasional high outbound network activity?
Apply traffic shaping to the port group that contains the virtual machine.
Convert traffic shaping from a vNetwork Standard Switch to a vNetwork Distributed Switch.
Apply traffic shaping to the other virtual machines in the same port group.
Apply traffic shaping to the virtual machine with high activity.

I’m not shure but the more likely is apply Traffic Shaping in port that contains virtual machine to bursts traffic.
Traffic Shaping Policy
A traffic shaping policy is defined by average bandwidth, peak bandwidth, and burst size. You can establish a traffic shaping policy for each port group and each distributed port or distributed port group. ESXi shapes outbound network traffic on standard switches and inbound and outbound traffic on distributed switches. Traffic shaping restricts the network bandwidth available on a port, but can also be configured to allow bursts of traffic to flow through at higher speeds.
