Dell EMC Dell XtremIO Maintenance Achievement D-XTR-MN-A-24 Exam Practice Test

Answer : C

The XtremIO X2 WebUI is based on HTML5 technology. HTML5 is the latest version of the Hypertext Markup Language, the code that describes web pages. It's actually three kinds of code: HTML, which provides the structure; Cascading Style Sheets (CSS), which take care of presentation; and JavaScript, which makes things happen1.

HTML5 is designed to deliver almost everything you'd want to do online without requiring additional software such as browser plugins. It does everything from animation to apps, music to movies, and can also be used to build complicated applications that run in your browser.

XtremIO X2's use of HTML5 allows for a more interactive and responsive WebUI that is compatible with a wide range of devices, including tablets and smartphones, providing a better user experience and easier management of the storage array1.

Answer : C

In the event of a power failure, the XtremIO X2 array is designed to protect the journal data using a combination of Supercapacitor and NVRAM. The NVRAM (Non-Volatile Random Access Memory) ensures that the data remains intact without power, while the supercapacitor provides the necessary energy to maintain the power to the NVRAM during the outage. This design allows the XtremIO X2 array to preserve the integrity of the journal data until normal power can be restored1.

Answer : B

In Dell XtremIO X2 arrays, the Disk Protection Groups (DPGs) are organized in such a way that each DPG spans multiple rows of drives. Specifically, DPG-2 in an XtremIO-X2 DAE (Disk Array Enclosure) uses the drives in Row 1 and Row 2. This configuration is designed to ensure redundancy and fault tolerance. The drives in these rows collectively form the DPG, which is responsible for data protection and performance optimization.

Answer : C

The minimum XtremIO software version required for expanding a Starter X-Brick cluster is 4.0.4. This version includes the necessary features and improvements to support the expansion process, ensuring compatibility and optimal performance.

Answer : C

For uploading the XtremApp to the XtremIO Management Server (XMS), the recommended tool is WinSCP. WinSCP is a popular SFTP client and FTP client for Microsoft Windows that allows for secure file transfer between a local and a remote computer1. It is particularly useful for uploading files like XtremApp due to its graphical user interface, which simplifies the process of transferring files.

The steps for uploading the XtremApp to the XMS using WinSCP are as follows:

Download and install WinSCP on your local machine.

Open WinSCP and enter the XMS's hostname or IP address, as well as the username and password.

Navigate to the XtremApp file on your local machine within the WinSCP interface.

Drag and drop the XtremApp file to the desired directory on the XMS.

Verify that the upload was successful by checking the file size and timestamp on the XMS.

This method is recommended in the Official Dell XtremIO Maintenance Achievement document as it provides a secure and reliable way to manage files on the XMS1.

Answer : D

To expand a Starter X-Brick cluster (which typically begins with one X-Brick) to an eight X-Brick cluster, a total of three expansions are required. Each expansion step in XtremIO can typically double the number of X-Bricks, thus:

First expansion: From 1 X-Brick to 2 X-Bricks.

Second expansion: From 2 X-Bricks to 4 X-Bricks.

Third expansion: From 4 X-Bricks to 8 X-Bricks.

This sequence ensures that the storage array scales properly, maintaining performance and redundancy.

Answer : C

Questions no: Which document contains the detailed steps for re-imaging the Storage Controller when preparing for a single-to-dual X-Brick expansion?

Verified Answer: C. XtremIO Hardware Installation and Upgrade Guide

Step by Step Comprehensive Detailed Explanation with Reference: The detailed steps for re-imaging the Storage Controller when preparing for a single-to-dual X-Brick expansion are contained in the XtremIO Hardware Installation and Upgrade Guide. This document provides comprehensive instructions on the physical installation, initial configuration, and upgrade procedures for XtremIO hardware components, including the process of re-imaging the Storage Controller1.

The steps typically include:

Ensuring that all data is backed up before starting the re-imaging process.

Verifying the current system configuration and health status.

Following the specific instructions for re-imaging the Storage Controller as outlined in the guide.

Performing post-re-imaging tasks such as system verification and configuration as necessary.

It is important to follow the guide closely to avoid any potential issues during the expansion process1.
