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

Answer : A

In a multi X-Brick XtremIO X1 cluster, the failure of more than half of the COM (communication) cables forces the cluster into a degraded mode. This degraded mode is a protective measure to ensure that the cluster can continue operating with reduced performance and redundancy until the issues with the COM cables are resolved.

Answer : C

The field replaceable units (FRUs) on an XtremIO X1 Storage Controller include the entire component and the Power Supply Unit (PSU). This information is verified as per the Official Dell XtremIO Maintenance Achievement document, which outlines the FRU replacement procedures for XtremIO products1.

Answer : C

To successfully operate Technician Advisor on an XtremIO X2, TCP ports 80 and 443 need to be open between the XMS (XtremIO Management Server) and X1-SC1 (Storage Controller). These ports are used for HTTP and HTTPS communication, respectively, allowing for secure management and operation of the storage system.

Answer : B

This performance metric is derived from the system's ability to deliver linear scalability, meaning that two X-Bricks can deliver twice the IOPS of a single X-Brick configuration2.

The calculation for this is based on the performance of a single X-Brick, which can achieve up to 300,000 IOPS under the same workload conditions. Therefore, with two X-Bricks, the system can achieve double that amount, resulting in 600,000 IOPS1.

This information is crucial for planning and sizing purposes, ensuring that the storage array meets the performance requirements of the applications it supports2.

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 : A

A key feature of the XtremIO storage array is inline compression. This feature allows data to be compressed in real-time as it is written to the storage system, which helps to reduce storage footprint and improve storage efficiency without impacting performance.

Answer : B

In a multi X-brick cluster, each X-brick consists of multiple Disk Array Enclosures (DAEs) that work together to provide storage and data redundancy.

If both DAE controllers in a single X-Brick fail, the impact is localized to the LUNs (Logical Unit Numbers) that store data on that particular DAE.

The entire cluster does not shut down; rather, only the data on the affected DAE becomes unavailable.

This design ensures that the rest of the cluster continues to operate normally, albeit with potential performance degradation depending on the data distribution and workload.
