Dell EMC D-XTR-DY-A-24 Dell XtremIO Deploy Achievement Exam Practice Test

Answer : B

The largest size supported for each volume in a new XtremIO X2-S single X-Brick cluster, as per the Official Dell XtremIO Deploy Achievement documents, is 64 TB. This information is verified through the official documentation which outlines the capabilities and specifications of the XtremIO X2 systems. The documents provide a detailed description of the critical components, features, and implementation solutions in customer environments, which includes the storage capacity specifications for XtremIO systems1.

Answer : D

To interact with an XtremIO cluster using the REST API, the application that can be used is cURL. cURL is a command-line tool and library for transferring data with URLs and is commonly used for various types of HTTP requests.

The steps to use cURL with the XtremIO REST API are as follows:

Install cURL: Ensure that cURL is installed on your system. It is available for a variety of platforms including Windows, Mac, and Linux.

Prepare the API Request: Formulate your REST API request. This will include the XtremIO cluster's endpoint and the specific API call you wish to make.

Execute the cURL Command: Use the cURL command in your terminal or command prompt to execute the API request. The general syntax for a cURL request is:

curl [options] [URL]

For example, to list all volumes on an XtremIO cluster, you might use:

curl -u username:password -X GET 'https://XMS_IP_Address/api/json/v2/types/volumes'

Replace username:password with your actual credentials and XMS_IP_Address with the IP address of your XtremIO Management Server (XMS).

Analyze the Response: The response from the XtremIO cluster will be output to your terminal. It will typically be in JSON format, which you can then parse and analyze as needed.

Reference Documentation: For detailed information on the REST API calls available and their usage, refer to the official Dell XtremIO Deploy Achievement document1. This document will provide comprehensive guidance on implementing solutions using XtremIO systems, including the use of REST API for cluster interaction.

By following these steps and referring to the official documentation, you can successfully use cURL to interact with an XtremIO cluster via the REST API.

Answer : D

In an environment with multiple XtremIO X1 clusters running different versions of XtremIO software, the minimum number of XtremIO Management Servers (XMS) required is determined by the compatibility and management requirements of the clusters.

Compatibility Check: Verify the compatibility of XMS with different versions of XtremIO software. An XMS can manage clusters running the same major version of software.

Management Requirements: Assess the management requirements for the clusters. Each XMS can manage multiple clusters, but there may be limitations based on the software version and scalability limits.

Scalability Limits: Consider the scalability limits of the XMS. For example, an XMS managing multiple clusters may have a global limit on the number of volumes it can manage across all clusters1.

Determine the Minimum Number: Based on the above factors, determine the minimum number of XMS servers required. In this case, since there are two distinct software versions (4.0.4-41 and 3.0.3-11), at least two XMS servers would be needed---one for each software version group.

Official Documentation: Consult the official Dell XtremIO Deploy Achievement document for specific guidelines and instructions. The document will provide the authoritative steps and references for setting up and managing the XMS in a multi-cluster environment.

In conclusion, for four XtremIO X1 clusters with two different software versions, a minimum of two XMS servers is required---one for the clusters running software 4.0.4-41 and another for those running software 3.0.3-11. This ensures proper management and compatibility across the clusters.

Answer : A

In the event of a power failure, the XtremIO X2 system's NVRAM (Non-Volatile Random Access Memory) card will initiate the discharging of the SuperCapacitor (SuperCap). The SuperCap is designed to provide enough power to the NVRAM card to allow it to write any data in transit to a non-volatile storage medium, ensuring data integrity and preventing loss1. This process is a critical part of the XtremIO X2's data protection mechanism during unexpected power interruptions.

Answer : C

To update the Install base record for Dell XtremIO in addition to the PSNT, the following data needs to be provided:

Microcode Version: This refers to the firmware version running on your XtremIO system. It's essential to have the latest microcode version reported for support and maintenance purposes.

Installation Configuration: This includes details about the XtremIO system's setup, such as cluster configuration, number of X-Bricks, and any custom settings applied during the installation.

The process of updating the Install base record typically involves:

Gathering Information: Collect the microcode version from the XtremIO Management Server (XMS) interface and document the installation configuration details.

Submitting the Data: Provide the collected information to Dell Support or through the appropriate channel as directed in the Dell XtremIO Deploy Achievement documentation.

Verification: Dell Support may verify the provided information against their records and the actual system configuration to ensure accuracy.

Record Update: Once verified, Dell Support will update the Install base record with the new information.

For detailed instructions and the official procedure, refer to the Dell XtremIO Deploy Achievement document1. It's crucial to follow the official guidelines to ensure that the Install base record is accurately updated, which can be critical for effective support and maintenance of the XtremIO system.

Answer : D

The maximum number of 10 TB X-Bricks that can be configured in an XtremIO X1 cluster is four. This information is based on the data available up to my last update in 2021 and the search results obtained from the web.

Understanding X-Bricks: An X-Brick is the storage building block of an XtremIO system. Each X-Brick contains SSDs and provides a certain amount of storage capacity.

Cluster Configuration: The XtremIO X1 cluster is designed to scale out by adding additional X-Bricks to increase performance and capacity.

Maximum Number: At launch, the XtremIO platform supported up to 4 X-Bricks1. This allowed for expansion within a single cluster by adding more X-Bricks as needed.

Reference to Official Documentation: For the most accurate and up-to-date information, it is essential to refer to the latest official Dell XtremIO Deploy Achievement documents. These documents provide detailed specifications, including the maximum number of X-Bricks supported in different configurations.

Consulting Dell Support: If there have been updates or changes after my last knowledge update in 2021, consulting Dell support or the latest technical documentation would provide the current specifications.

In summary, based on the information available, the maximum number of 10 TB X-Bricks that can be configured in an XtremIO X1 cluster is four. However, always refer to the latest official documentation or Dell support for the most current information.

Answer : D

The recommended way to check the connectivity of DAE controllers, IB switches, IPMI, and BBU on an XtremIO X1 multi X-Brick after software installation and before cluster creation is to use the XMCLI (XtremIO Management Command Line Interface). The XMCLI provides commands to test connectivity and confirm that all components are healthy and connected within the cluster. Here are the steps:

Access XMCLI: Log into the XtremIO Management Server (XMS) and access the XMCLI.

Run Connectivity Tests: Use the test-xms-storage-controller-connectivity command to check the connectivity of the storage controllers. Similar commands are available for other components1.

Review Test Results: Analyze the output of the commands to ensure that there is no packet loss and that the response times are within acceptable limits.

Troubleshoot if Necessary: If any connectivity issues are detected, use the XMCLI to troubleshoot and resolve them before proceeding with the cluster creation.

Document the Process: Keep a record of the connectivity checks and any actions taken to resolve issues as part of the installation documentation.
