The correct answer is A. Increase the number of vCPUs for PVMAPP_0. When vRealize Operations Analysis indicates CPU contention or saturation as the root cause of VM health alerts, the correct remediation is to increase the number of vCPUs allocated to the VM.

Why each option
When vRealize Operations Analysis indicates CPU contention or saturation as the root cause of VM health alerts, the correct remediation is to increase the number of vCPUs allocated to the VM.
When the vRealize Operations Analysis pane identifies CPU demand exceeding available vCPU capacity - evidenced by high CPU ready time or CPU demand approaching 100% - increasing the vCPU count gives the VM additional parallel processing threads to satisfy its workload, directly addressing the CPU bottleneck identified in the alert.
Increasing memory allocation addresses memory balloon or swap-driven performance issues; if the Analysis pane identifies CPU as the primary contention metric, adding RAM does not resolve CPU-driven degradation.
Increasing the memory limit only helps when an artificially low limit is capping the VM's usable memory - this is a memory-specific configuration action that has no effect on a CPU performance problem.
Increasing the CPU reservation in MHz guarantees a minimum floor of CPU resources but does not expand the total number of vCPUs available; when the VM needs more parallel processing capacity, adding vCPUs is the correct fix rather than reserving more of the existing allocation.
