Dell EMC Dell XtremIO Maintenance Achievement Exam Practice Test

Answer : B

The SAS (Serial Attached SCSI) connection speed for an XtremIO X1 is 6 Gb/s, while for an XtremIO X2, it is 12 Gb/s. The increased speed in the X2 model enhances data transfer rates and overall performance, reflecting advancements in the hardware capabilities of the newer generation.

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

To replace a power supply unit (PSU) in a storage controller of an XtremIO cluster, a specific command needs to be executed.

The correct command to initiate this process is replace-storage-controller-psu sc-psu-id=1 cluster-id='ABC123'.

This command specifies the action to replace the PSU (replace-storage-controller-psu), the PSU ID (sc-psu-id=1), and the specific cluster ID (cluster-id='ABC123').

Using this command ensures that the correct PSU in the specified cluster is prepared for replacement.

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.
