Dell EMC Dell XtremIO Maintenance Achievement Exam Practice Test

Answer : C

When creating a cluster, in addition to the cluster name, the following parameters are required: the expected number of X-Bricks, the IP address of X1-SC1 (the first Storage Controller), and the package name. These parameters are essential for setting up the cluster configuration and ensuring proper communication between components.

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 : A

When connected to the Tech port on a Dell XtremIO Storage Controller, the login name 'xinstall' should be used to test the Storage Controller cabling. This special login is designated for installation and configuration tasks, including testing and verifying cabling connections to ensure proper setup and functionality of the storage system.

Answer : C

Before an XtremIO X1 cluster can start, it is required that the Battery Backup Units (BBUs) are charged to at least 70%. This ensures that there is sufficient power reserve to maintain data integrity and allow for safe shutdown procedures in case of an unexpected power loss. The BBUs provide power to the Storage Processors and other critical components during an outage, allowing them to complete any in-progress operations and commit data to SSDs1.

The startup process checks the BBU charge level and will only proceed if the minimum charge requirement is met. This is a safety feature designed to protect the system and the data it holds. If the BBUs are not adequately charged, the system will not start, preventing potential data loss or corruption that could occur if the system were to lose power without the ability to properly shut down1.

Answer : D

In preparation for a single-to-dual online cluster expansion, the power cables that are pre-staged by being connected to Power Distribution Unit B (PDU-B) only are for the right-side Power Supply Units (PSUs) of the Storage Controllers (SCs). Specifically, these would be the power cables for X2-SC1-PSU-R and X2-SC2-PSU-R. This configuration ensures that there is a balanced power distribution across the PDUs and that the new cluster components will have power connectivity once they are physically installed1.

The process typically involves:

Identifying the correct power cables for the SCs' PSUs.

Connecting these cables to the designated ports on PDU-B.

Ensuring that the cables are properly managed and labeled for easy identification during the expansion process.

This procedure is part of the standard practices for expanding an XtremIO cluster, as detailed in the Official Dell XtremIO Maintenance Achievement document1.

Answer : B

When deploying a virtual XtremIO Management Server (XMS), the template uses the file name extension .ova. This is a standard format for virtual appliances, which are pre-configured virtual machines that can be imported and run on various virtualization platforms. The .ova file extension stands for Open Virtual Appliance (or Application) and is typically used for packaging and distributing software to be run in virtual machines1.

The deployment process using an .ova file typically involves the following steps:

Download the .ova file from the official source or portal.

Import the .ova file into the virtualization platform (such as VMware vSphere or Oracle VM VirtualBox).

Follow the prompts to configure the virtual machine settings as needed.

Once the import is complete, power on the virtual machine to begin the initial setup and configuration of the virtual XMS server.

This information is consistent with the practices outlined in the Official Dell XtremIO Maintenance Achievement document, ensuring that the deployment of the virtual XMS server aligns with Dell's recommended procedures2.

Answer : A

For an XtremIO X2-S, the ports used on the InfiniBand switches for an Inter-Switch Link (ISL) connection are typically high-numbered ports, which are usually at the end of the port range on the switch. While the specific port numbers can vary depending on the switch model and configuration, ports 35 and 36 are commonly used for ISL connections in many configurations1.

The process to identify the ISL ports is as follows:

Access the InfiniBand switch via the management interface.

Use the appropriate command to list the port configuration (this command can vary based on the switch's firmware).

Identify the ports configured for ISL, which will be indicated in the port configuration settings.

It's important to refer to the official Dell XtremIO Maintenance Achievement document or the InfiniBand switch documentation for the exact port numbers as they can differ based on the switch model and the cluster configuration1.
