Question
An administrator is experiencing storage performance issues on a Windows Server 2019 VM with the following configuration:
vCPU: 1 VRAM: 8 GB vSCSI: VirtIO SCSI Controller vDisk: 2 (100 GB, 250 GB) vNIC: VirtIO Fast Ethernet The AHV cluster is healthy, and other Windows VMs are performing well. Which configuration change should be reviewed to enhance VM performance?
Options
- AAdd a second virtual storage controller (vSCSI).
- BEnable Balance-TCP on bridge (br0).
- CIncrease Controller VM (CVM) resources.
- DIncrease the VM's number of vCPUs.

Explanation
A single vCPU is likely causing a bottleneck, limiting the VM's ability to process I/O requests Option D (Increase the VM's number of vCPUs) is correct: Windows requires sufficient CPU resources to handle disk and network operations. Adding more vCPUs allows the VM to process more I/O operations simultaneously, improving performance.
