A. B. C. D.CD.
Of the options given, the two guest virtual machine components that provide the best performance in a View virtual desktop are vmxnet3 and PVSCSI.
vmxnet3: vmxnet3 is a VMware virtual network adapter. It is the latest and most advanced virtual NIC (Network Interface Card) offered by VMware. vmxnet3 is optimized for high performance and low CPU usage. Compared to the other virtual NICs, vmxnet3 provides the highest throughput, lowest CPU utilization, and lowest latency. It also has a number of advanced features, such as support for jumbo frames and hardware offloading.
PVSCSI: PVSCSI is a VMware paravirtualized SCSI adapter. It is a specialized adapter that provides improved I/O performance and lower CPU utilization compared to the other SCSI adapters. PVSCSI is optimized for high throughput, low latency, and low CPU usage. It also provides advanced features such as support for up to 64 virtual disks per virtual machine and support for vSphere Fault Tolerance.
BusLogic and e1000 are also virtual adapters, but they are not as optimized for performance as vmxnet3 and PVSCSI.
BusLogic: BusLogic is an older virtual SCSI adapter that is still supported by VMware. However, it is not as performant as the other options listed. It has been replaced by PVSCSI in newer versions of VMware.
e1000: e1000 is a virtual NIC that emulates an Intel 82545EM Gigabit Ethernet NIC. While it is a good general-purpose virtual NIC, it is not as optimized for performance as vmxnet3.
In summary, vmxnet3 and PVSCSI are the two guest virtual machine components that provide the best performance in a View virtual desktop due to their optimizations for high throughput, low latency, and low CPU utilization.
