Nutanix Certified Associate (NCA) — Questions and Answers

Question 1: Why is written communication important in Nutanix Exam practice?

Modern technology has eliminated the need for written communication
It is less effective than verbal communication in all situations
Written records are only needed for legal disputes
It creates a permanent record, ensures clarity, and provides reference for future actions (Correct answer)

Correct answer: It creates a permanent record, ensures clarity, and provides reference for future actions

Written communication creates documented records, provides clarity through careful word choice, allows review before sending, and serves as reference material for decisions and future actions.

Question 2: What AHV feature enables a running VM to be moved to a different host without any downtime?

Live migration (Correct answer)
Cold migration
Cluster node expansion
Snapshot and restore

Correct answer: Live migration

AHV live migration transfers a running VM between hosts transparently with no service interruption, similar to VMware vMotion.

Question 3: Which Nutanix report helps identify which hosts in a cluster are most heavily utilized to support workload rebalancing decisions?

Protection Domain Status Report
Data Resiliency Report
Host Performance Summary Report (Correct answer)
Erasure Coding Efficiency Report

Correct answer: Host Performance Summary Report

The Host Performance Summary Report shows per-host CPU, memory, and storage utilization, helping administrators identify hotspots for workload rebalancing.

Question 4: Which Nutanix licensing tier is required to access advanced features like Calm and Flow?

Starter
Foundation
Ultimate (Correct answer)
Pro

Correct answer: Ultimate

The Ultimate license tier unlocks the full Nutanix feature set, including Calm (automation) and Flow (microsegmentation).

Question 5: What is the primary operational benefit of enabling memory overcommit in AHV?

It accelerates VM performance by transparently compressing memory pages
It enables live migration of VMs with very large memory footprints
It allows more VMs to run on a host than the physical RAM would normally support (Correct answer)
It reduces storage overhead for VM virtual disk images

Correct answer: It allows more VMs to run on a host than the physical RAM would normally support

Memory overcommit increases VM density by allowing the hypervisor to schedule physical RAM among more VMs than could fit if each VM's maximum allocation were fully reserved.

Question 6: A single AHV cluster node will fail to function when the cluster is configured using the default settings. <br> What will happen with the virtual machines (VMs) that are currently running on that node?

The cluster attempts to restart VMs on other hosts (Correct answer)
The VMs do a live migration to the master node in the cluster
The cluster restarts all VMs in the event of a host failure
The VMs do a live migration to any other node in the cluster

Correct answer: The cluster attempts to restart VMs on other hosts

When a host in a cluster experiences a failure or becomes unavailable, the cluster detects the failure and attempts to restart the affected virtual machines on other available hosts within the cluster. <br> VM resiliency or VM restart is an important feature for maintaining high availability and minimizing downtime in virtualized environments. It helps ensure that virtual machines continue to operate even in the face of host failures or disruptions.

Question 7: A Nutanix engineer is asked to create a knowledge base article about a recurring connectivity issue for helpdesk staff. What is the most important characteristic of this document?
