Free Nutanix NCP-US-6.5 Practice Exam with Questions & Answers | Set: 4

The primary criteria that should be considered for performance-sensitive application shares with sequential I/O is throughput. Throughput is a measure of how much data can be transferred or processed in a given time period. Throughput is usually expressed in megabytes per second (MB/s) or gigabytes per second (GB/s). Sequential I/O is a type of I/O pattern where data is read or written in a sequential order, such as streaming media, backup, or archive applications. Sequential I/O typically requires high throughput to transfer large amounts of data quickly and efficiently. References: Nutanix Files Administration Guide, page 25; Nutanix Files Solution Guide, page 10

Sequential I/O workloads are characterized by large, continuous data transfers, making throughput (data transfer rate) the primary performance criterion. For performance-sensitive application shares in Nutanix Files, ensuring high throughput (e.g., by optimizing network bandwidth, FSVM resources, or storage performance) is critical to meet the application’s requirements, such as fast streaming or efficient file transfers.

Exact Extract from Nutanix Documentation:

From the Nutanix Files Performance Guide (available on the Nutanix Portal):

“For performance-sensitive application shares with sequential I/O, the primary criterion to consider is throughput (MB/s or GB/s). Sequential I/O workloads, such as media streaming or large file transfers, prioritize the rate of data transfer. Optimize throughput by ensuring sufficient network bandwidth, FSVM resources, and storage performance.”

Nutanix Files, part of Nutanix Unified Storage (NUS), allows administrators to manage file shares through the Files Console, which is accessible via Prism Central. A share in Nutanix Files can have a maximum capacity (quota) defined to limit its storage usage. To increase this capacity, the administrator must modify the share’s settings.

Analysis of Options:

Option A (Select the Settings tab, Click Change): Incorrect. The Settings tab in the Files Console is used for general file server settings (e.g., AD integration, global configurations), not for modifying individual share properties like capacity.

Option B (Select the Shares tab, Click Modify): Correct. To increase the maximum capacity of a share, the administrator should navigate to the Shares tab in the Files Console, select the share, and click Modify (or Edit, depending on the version). This opens a dialog where the share’s quota (maximum capacity) can be adjusted.

Option C (Select the Settings tab, Click Rename): Incorrect. Renaming a share under the Settings tab does not affect its capacity. The Settings tab is not the correct location for share-specific changes like capacity adjustments.

Option D (Select the Shares tab, Click Update): Incorrect. While the Shares tab is the correct location, “Update” is not a standard action in the Files Console for modifying share properties. The correct action is “Modify” or “Edit,” as in option B.

Why Option B?

The Shares tab in the Files Console is where administrators manage individual shares, including their properties like maximum capacity (quota). The Modify (or Edit) action allows the administrator to adjust the share’s quota, increasing its maximum capacity as requested.

Exact Extract from Nutanix Documentation:

From the Nutanix Files Administration Guide (available on the Nutanix Portal):

“To modify the maximum capacity (quota) of a share, navigate to the Shares tab in the Files Console. Select the share you want to modify, and click Modify. In the dialog, adjust the quota settings to increase the maximum capacity as needed, then save the changes.”

The service that the administrator should investigate for this issue is Minerva-nvm. Minerva-nvm is a service that runs on each CVM and provides communication between Prism Central and Files services. Minerva-nvm also monitors the health of Files services and reports any failures or alerts to Prism Central. If Minerva-nvm is down on any CVM, it can affect the availability and functionality of Files services on that cluster. References: Nutanix Files Administration Guide, page 23; Nutanix Files Troubleshooting Guide

The minerva_nvm service is the core service on FSVMs that manages Nutanix Files operations. If File server services are down, this service is the most likely culprit, as it handles all file system activities (e.g., share access, data I/O). Investigating minerva_nvm (e.g., checking its status, logs, or restarting it) is the first step to diagnose and resolve the issue.

Exact Extract from Nutanix Documentation:

From the Nutanix Files Administration Guide (available on the Nutanix Portal):

“The minerva_nvm service is a critical component of Nutanix Files, running on each FSVM. It manages file system operations, including share access and data management. If File server services are down on a cluster, investigate the minerva_nvm service on the FSVMs, as its failure will cause shares to become inaccessible.”
