An administrator is unable to configure Receive Side Scaling on the vmnic driver in a Windows
2008 R2 guest.
Based on the exhibit, what would need to be modified to enable this option?
A.
Manually configure a static MAC address
B.
Enable DirectPath I/O
C.
Ensure the vmnic is attached to the correct network
D.
Change the adapter type to VMXNET3
Explanation:
VMXNET 3: The VMXNET 3 adapter is the next generation of a paravirtualized NIC designed for performance, and is not related to VMXNET or VMXNET 2. It offers all the features available in VMXNET 2, and adds several new features like multiqueue support (also known as Receive Side Scaling in Windows), IPv6 offloads, and MSI/MSI-X interrupt delivery. For information about the performance of VMXNET 3, see Performance Evaluation of VMXNET3 Virtual Network Device. Because operating system vendors do not provide built-in drivers for this card, you must install VMware Tools to have a driver for the VMXNET 3 network adapter available.
