Analyze and Optimize VM Performance

An administrator runs a custom backup application on Windows that requires a 2 TB disk. Its throughput is substantially below expectations. The application is installed on a VM configured with:

  • Four vCPUs, with one core per vCPU
  • 4 GB of memory
  • One 50 GB vDisk for the Windows installation
  • One 2 TB vDisk for the application

What configuration change is recommended 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
Explanation

Striping the application volume across multiple vDisks enables parallel I/O streams and increases the available storage-throughput ceiling compared with a single large virtual disk. VMware guidance notes that multiple VMDKs, particularly when paired with appropriate virtual SCSI configuration, improve the guest’s ability to queue additional I/O.
