Which statement describes the functionality of traffic shaping on a vSphere Standard Switch?

Which statement describes the functionality of traffic shaping on a vSphere Standard Switch?

A.
vSphere Standard Switches support only egress traffic shaping.

B.
vSphere Standard Switches support both ingress and egress traffic shaping.

C.
vSphere Standard Switches support best-effort traffic shaping based on quality of service
(QoS).

D.
vSphere Standard Switches support only ingress traffic shaping.

Explanation:
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.
