Why should memory and network utilization be used to identify bottlenecks?

While excessive memory and network can slow vDisk loading, this option is less specific than option B, which directly ties the vDisk store utilization to the PXE boot process, a critical initial step.

The PXE boot process for Provisioning Services heavily relies on network communication to retrieve the bootstrap file and initial boot components, often from the PVS server which accesses the vDisk store. Excessive network utilization (contention) or memory pressure on the PVS server or the underlying vDisk store components involved in this initial boot phase will introduce significant latency, directly slowing down the PXE boot sequence for target devices.

Excessive memory and network utilization does not directly cause fragmentation of the TFTP bootstrap file; fragmentation is a disk-level attribute.

Excessive memory and network utilization does not directly cause fragmentation of vDisks; vDisk fragmentation is a consequence of storage usage and management.
