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

Answer : A

ESRS (EMC Secure Remote Services) configuration verification is typically done using commands that check for system notifications and configurations.

The show-syslog-notifier command is used to verify the settings and configuration of syslog notifications, which is part of the ESRS setup.

This command helps in ensuring that the notifications are correctly configured and functioning as intended, allowing for remote monitoring and management.

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 : A

The XtremIO X2 storage system can be expanded for capacity (Scale-Up) or both capacity and performance (Scale-Out). The system begins with a single building block, called an X-Brick, with a minimum of 18 SSDs. When additional capacity is required, the system scales up, with up to 72 SSDs for a single X-Brick1. Therefore, to upgrade a single X-Brick XtremIO X2 cluster that already contains 36 SSDs, the minimum number of SSDs required would be 18, which is the base configuration for an X-Brick.

=========================

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 : B

In an XtremIO X1 system, a full data protection group (DPG) can tolerate the loss of up to 5 drives before a data loss occurs. The XtremIO architecture ensures high availability and redundancy, but losing more than 5 drives within a DPG exceeds the system's ability to protect data, leading to potential data loss.

Answer : B

When comparing XtremIO X1 to XtremIO X2, the amount of memory installed in a Storage Controller with a DAE attached with 400 GB SSDs differs. For the X1, it is 256 GB, while for the X2, it is 512 GB. This increase in memory in the X2 model supports higher performance and improved handling of data operations.

Answer : C

The XtremIO Storage Array Site Preparation Guide contains the power requirements for the XtremIO system. This guide includes detailed specifications for power consumption, electrical requirements, and other environmental factors necessary for proper installation and operation.
