Question 1

Which memory overcommit feature in AHV allows more vRAM to be allocated across VMs than the physical RAM available on a host?

Accepted Answer

Memory Overcommit is not supported in AHV

Answer

AHV does not support memory overcommit; each VM's allocated memory must be backed by physical RAM on the host, ensuring predictable performance.

Question 2

In Nutanix Prism, what metric is used to measure the actual storage I/O performance of a VM at a given moment?

Accepted Answer

IOPS (Input/Output Operations Per Second)

Answer

IOPS is the primary metric displayed in Prism to measure how many read and write operations a VM is performing per second.

Question 3

What is the purpose of the 'Guest Customization' feature when deploying VMs from templates in Nutanix?

Accepted Answer

Configures unique host settings like hostname, IP, and SID during first boot

Answer

Guest Customization (Sysprep for Windows, cloud-init for Linux) automatically configures VM-specific settings like hostname and network during the first boot.

Question 4

Which Nutanix feature allows administrators to set minimum, maximum, and burst resource limits for VM CPU and memory?

Accepted Answer

VM Resource Policies

Answer

VM Resource Policies in Nutanix allow administrators to define minimum guaranteed resources, maximum caps, and burst limits for individual VMs.

Question 5

When performing a VM disk hot-add in AHV, what is a key requirement for the operation to succeed without a reboot?

Accepted Answer

The guest OS must support SCSI hot-plug and have appropriate drivers

Answer

Hot-adding a disk without rebooting requires the guest OS to support SCSI hot-plug, which modern Windows and Linux distributions typically support with appropriate drivers.
