Which of the following resource management techniques could be used to relieve a network bottleneck caused by a VM with occasional high outbound network activity?

A.
apply traffic shaping to the VM with high activity

B.
apply traffic shaping to the port group containing the virtual machine

C.
convert the switch from a vNetwork Standard Switch to a vNetwork Distributed Switch

D.
apply traffic shaping to the other VMs in the same port group

Explanation:
Edit the Traffic Shaping Policy for a Virtual Switch – Vcenter Help ESX/ESXi allows you to shape outbound traffic on virtual switches. The traffic shaper restricts the network bandwidth available to any port, but may also be configured to temporarily allow "bursts" of traffic to flow through a port at higher speeds.

Procedure:
1/ Log in to the vSphere Client and select the server from the inventory panel.
2/ Click the Configuration tab and click Networking.
3/ Select a vSwitch and click Properties.
4/ Click the Ports tab.
5/ Select the vSwitch and click Edit.
6/ Click the Traffic Shaping tab.
7/ Select Enabled from the Status drop-down menu to enable traffic shaping policy exceptions. The Status policy here is applied to each virtual adapter attached to the port group, not to the vSwitch as a whole. If you enable the policy exception in the Status field, you set limits on the amount of networking bandwidth allocation for each virtual adapter associated with this particular port group. If you disable the policy, services have a clear connection to the physical network by default.
8/ For each traffic shaping policy, enter a bandwidth value.
