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

Answer : C

For an XtremIO X2-R four X-Brick cluster, the total number of rack units that should be left for the Cable Management ducts (CMD) is 4U1. This is based on the specifications provided by Dell EMC, which indicate that the Cable Management ducts are optional and, when included, require 2U of rack space for a two-brick cluster. Therefore, for a four-brick cluster, it would be logical to double the space to 4U to accommodate the additional cabling and ensure proper cable management1.

The process for allocating space for CMDs involves:

Reviewing Specifications: Check the official XtremIO X2 specifications to determine the space requirements for CMDs.

Allocating Rack Space: Based on the specifications, allocate the necessary rack units for CMDs within the customer's rack.

Installing CMDs: Install the CMDs in the allocated space to manage the cables effectively.

Organizing Cables: Arrange and secure the cables within the CMDs to ensure a neat and organized cable layout.

Verifying Installation: Confirm that the CMDs are installed correctly and that all cables are managed properly without any strain or interference.

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.

Answer : B

For an XtremIO X2 dual X-Brick cluster configuration without a physical XMS installed, the total number of power connectors required in a customer rack is 8. This is based on the system specifications which state that a 2 Brick Cluster requires 16 x IEC C14 power sockets1. Since the physical XMS would typically require additional power sockets, and it is not included in this configuration, the total number of power connectors needed would be less than the specified 16.

Here's the breakdown:

Each X-Brick in a dual X-Brick configuration would require power for its controllers and DAEs.

The InfiniBand switches included in a multi X-Brick system would also require power.

Without the physical XMS, which would normally need its own power connectors, the total comes down to 8 connectors required for the dual X-Brick setup1.

Answer : D

For the integration of Oracle with XtremIO, the best practice for HBA drivers includes setting the LUN-queue depth to optimize performance. If a single host is connected to the X-Brick, the LUN-queue depth can be set to the maximum supported by the HBA, which is 256 for QLogic HBAs1. As additional hosts are added, this setting should be reduced proportionately until reaching a minimum of 32 to maintain optimal performance1.

Assess Host Connection: Determine the number of hosts connected to the X-Brick.

Set Queue Depth: For a single host, set the queue depth to 256. Adjust as necessary when more hosts are added.

Configure HBA Settings: Apply the queue depth setting in the HBA configuration.

Test Performance: Monitor the system's performance to ensure the settings are optimal.

Adjust if Necessary: If performance issues are observed, adjust the queue depth settings as needed.

Answer : D

When adding a user account in the XtremIO X2 XMS, the required information includes a unique user name, account type, and e-mail notification settings. Here's a detailed explanation:

Unique User Name: A unique identifier for the user account. This is essential to distinguish between different users and manage permissions accordingly.

Account Type: Specifies the level of access or role assigned to the user account, such as administrator, viewer, or custom roles with specific privileges.

E-mail Notification: Configuration settings for sending alerts and notifications to the user's e-mail address. This is important for monitoring and managing the system effectively.

Answer : D

When an XtremIO X2 array is delivered, the cable shown in the exhibit should be connected to the middle USB ports in both X3-SC1 and X3-SC2. This is based on the standard configuration and setup for XtremIO X2 arrays as per the Dell XtremIO Deploy Achievement document. The middle USB ports are typically used for specific functions such as connecting to a management network or interfacing with other devices that are part of the storage array infrastructure.

The process for connecting the cable is as follows:

Identify the Correct Ports: Locate the middle USB ports on both X3-SC1 and X3-SC2. These ports are usually marked and differentiated from other USB ports by their position or labeling.

Connect the Cable: Insert the USB connector end of the cable into the middle USB port on X3-SC1 and then connect the other end to the corresponding port on X3-SC2. Ensure that the connection is secure and that the cable is not obstructing any other components or airflow.

Verify the Connection: Once connected, verify that the cable is recognized by the system. This can typically be done through the XtremIO Management Server (XMS) interface or by checking the system's hardware configuration.

Check for Functionality: Ensure that the connected cable functions as intended. This may involve transferring data or accessing the management network, depending on the specific use case for the cable.

Reference Official Documentation: For detailed instructions and best practices, always refer to the official Dell XtremIO Deploy Achievement document1. This document provides comprehensive guidance on all aspects of setting up and managing XtremIO X2 arrays, including cable connections.

By following these steps and referring to the official documentation, you can ensure that the cable is connected correctly and that the XtremIO X2 array is set up for optimal performance and management.

Answer : A

During the installation of an XtremIO X1 system, the document that should be used to identify the ports for IPMI (Intelligent Platform Management Interface) cable connections is the XtremIO Storage Array Hardware Installation and Upgrade Guide. This guide typically contains detailed information about the hardware components, including diagrams and descriptions of the ports, which are essential for correctly connecting the IPMI cables.

The process of identifying the correct IPMI ports usually involves the following steps:

Locate the Guide: Access the XtremIO Storage Array Hardware Installation and Upgrade Guide. This document is designed to provide instructions specifically related to the physical components of the XtremIO system.

Identify the Ports: Use the diagrams and descriptions within the guide to locate the IPMI ports on the XtremIO hardware. These ports are typically labeled and may be color-coded to help distinguish them from other ports.

Connect the Cables: Once the IPMI ports have been identified, connect the IPMI cables to these ports as per the instructions provided in the guide. Ensure that the connections are secure and that the cables are not obstructing any other components.

Verify the Connections: After connecting the cables, verify that the connections match the diagrams and descriptions in the guide. This step is crucial to prevent any issues related to incorrect cabling.

Reference Documentation: For the most accurate and up-to-date information, always refer to the latest version of the XtremIO Storage Array Hardware Installation and Upgrade Guide1. This ensures that any changes or updates to the hardware are taken into account during the installation process.

By following these steps and referring to the correct documentation, you can ensure that the IPMI cable connections are made correctly, which is vital for the remote management and monitoring of the XtremIO X1 system.
