VCP Data Analysis & Reporting 4

Question 1

An administrator wants to compare CPU usage across all VMs in a cluster over the past week. Which vRealize Operations feature is best suited for this task?

Accepted Answer

Heat Map

Answer

Heat Maps in vRealize Operations visually compare metric values across multiple objects simultaneously, making it ideal for cluster-wide CPU usage comparison.

Question 2

What does the 'swapped' memory metric in vSphere indicate about a virtual machine?

Accepted Answer

The VM's memory has been written to the VMkernel swap file due to host memory pressure

Answer

Swapped memory indicates that the VMkernel has written the VM's memory pages to a .vswp swap file on disk because the host lacks sufficient physical RAM.

Question 3

In vCenter Server, which rollup type for historical performance data calculates the mean of all samples collected during a rollup period?

Accepted Answer

Average

Answer

The Average rollup type computes the arithmetic mean of all collected samples within a rollup interval, smoothing out short-term spikes.

Question 4

Which vRealize Operations report template is used to show VM rightsizing recommendations based on actual usage patterns?

Accepted Answer

VM Rightsizing Report

Answer

The VM Rightsizing Report in vRealize Operations identifies over-provisioned or under-provisioned VMs by comparing allocated resources to actual utilization.

Question 5

A vSphere administrator observes that network 'dropped packets' metric is increasing for a VM. What is the most likely cause?

Accepted Answer

The network buffer is overwhelmed and packets are being discarded

Answer

Dropped packets occur when the NIC's receive or transmit buffers are overwhelmed and the system cannot process packets fast enough, causing discards.
