An administrator has a custom backup application that requires a 2TB disk and runs in Windows. Throughput is considerably lower than expected. The application was installed on a VM with the following configuration:

1.

Four vCPUs with one core/vCPU

2.

4GB of Memory

3.

One 50GB vDisk for the Windows installation

4.

One 2TB vDisk for the application

What is the recommended configuration change to improve throughput?

A. Increase the number of cores per vCPU

B. Increase the vCPUs assigned to the VM

C. Span the 2TB disk across four vDisks

D. Add 4GB of memory to the VM

An administrator is planning to deploy a Nutanix cluster to support a few high-performance VMs. This deployment will have the following considerations:

1.

Individual VMs will likely generate network throughputs in the range of 90-100Mbps

2.

Due to the configuration of the VMs, it is unlikely that a node will host more than one or two of them at a time

3.

Individual VMs will communicate with only a few (one or two) remote hosts at a time

4.

Multicast will not be used in the environment

5.

The hosts are connected via two 1GbE network connections
