Click the Exhibit button. An administrator has received reports of poor network performance with a virtual machine. Which task will improve the network performance of this virtual machine?
A. Adjust shares for the virtual NIC on the virtual machine.
B. Traffic-shape this virtual machine.
C. Move the virtual machine to another virtual switch.
D. Add a CPU to the virtual machine.
Correct Answer: C
Explanation/Reference:
"Adjust shares for the virtual NIC on the virtual machine." – not possible to set/adjust shares on vNIC "Traffic-shape this virtual machine." – Traffic shape VM’s traffic; though on standard switch, this can only be done outbound, on a port-group – so yes this means from the vSwitch towards the VMs.In real world, just adding traffic shaping would solve the problem temporarily.
"Move the virtual machine to another virtual switch." – this is not clear either; it depends really – would the new switch have more uplinks?
"Add a CPU to the virtual machine." – Adding an extra CPU won’t fix network issues.
The jury is out on this: it could be traffic-shape or move to another vSwitch
