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 port group containing the virtual machine
B.
apply traffic shaping to the other VMs in the same port group
C.
apply traffic shaping to the VM with high activity
D.
convert the switch from a vNetwork Standard Switch to a vNetwork Distributed
Switch
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.
