Nutanix Exam Quality Assurance & Improvement 5

Question 1

Which Nutanix feature enables administrators to set I/O performance guarantees for specific VMs or storage containers?

Accepted Answer

Storage QoS (Quality of Service) policies

Answer

Storage QoS policies in Nutanix allow setting IOPS or throughput limits and reservations on storage containers to prevent noisy-neighbor issues.

Question 2

What is the significance of the 'Extent Store Usage' metric in Nutanix performance analysis?

Accepted Answer

It tracks the percentage of data blocks consumed in persistent storage after OpLog draining

Answer

Extent Store Usage reflects persistent storage consumption after write data has drained from OpLog, giving a true picture of backend storage utilization.

Question 3

A Nutanix administrator notices that OpLog usage remains persistently high. What does this most likely indicate?

Accepted Answer

Write I/O is exceeding the rate at which the system can drain to the Extent Store

Answer

Persistently high OpLog usage means incoming writes are outpacing the drain process, which can cause write latency increases as OpLog space fills.

Question 4

Which Nutanix Prism Central capability allows administrators to define and enforce policies that automatically remediate detected anomalies?

Accepted Answer

Prism Pro X-Play (Playbooks)

Answer

X-Play Playbooks in Prism Pro allow administrators to create automated workflows that trigger on alerts and take remediation actions like VM restart or notification.

Question 5

In a Nutanix environment, what is the purpose of running a 'log_collector' operation before engaging Nutanix Support?

Accepted Answer

To gather comprehensive cluster logs into a bundle for Support to analyze

Answer
