NCP-MCI-6.10 · Question #107

Which predefined view should be leveraged in Prism Central Intelligent Operations to determine which VM is consuming too many resources and causing other VMs to starve?

The correct answer is B. Bully VMs List. In Prism Central Intelligent Operations, the Bully VMs List identifies VMs that are aggressively consuming shared resources and causing performance degradation for neighboring VMs. This view is the correct tool for diagnosing resource starvation caused by a single VM.

Why each option

In Prism Central Intelligent Operations, the Bully VMs List identifies VMs that are aggressively consuming shared resources and causing performance degradation for neighboring VMs. This view is the correct tool for diagnosing resource starvation caused by a single VM.

AConstrained VMs List

The Constrained VMs List shows VMs that are being starved of resources, identifying victims rather than the cause of starvation.

BBully VMs ListCorrect

The Bully VMs List in Prism Central's VM Efficiency view flags virtual machines that consume a disproportionately high share of CPU, memory, or I/O resources relative to their peers, directly starving other co-located VMs. Identifying and right-sizing or migrating bully VMs resolves the noisy-neighbor problem described in the scenario.

CInactive VMs List

The Inactive VMs List surfaces VMs with very low utilization that may be candidates for decommissioning, not VMs over-consuming resources.

DOverprovisioned VMs List

The Overprovisioned VMs List identifies VMs allocated more resources than they actually use, which is a capacity-planning concern unrelated to causing starvation.
