Free Practice Questions for EMC D-XTR-MN-A-24 Exam

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.

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.

The highlighted port in the exhibit is a Fibre Channel (FC) port. This port type is used for high-speed data transfer between the storage controller and connected devices or networks. Fibre Channel is a technology known for its reliability and speed, making it suitable for storage area networks (SANs).The identification of the FC port is based on recognizing the physical characteristics of FC ports, such as their shape and typical placement on storage devices, as well as knowledge about Dell’s XtremIO systems’ configuration options1.

=========================

The correct racking order from bottom to top to expand an XtremIO X1 configuration from a dual X-Brick to a quad X-Brick is as follows:

X3-SC1

X3-DAE

X3-BBU

X3-SC2

As per the image provided, which appears to be a list or part of a document detailing the steps for racking components, the order listed for expanding an XtremIO X1 configuration is:

Begin with the bottom component, which is ‘X3-SC1’ (Storage Controller 1).

Above ‘X3-SC1’, install ‘X3-DAE’ (Disk Array Enclosure).

Next, install ‘X3-BBU’ (Battery Backup Unit) above ‘X3-DAE’.

Finally, at the top, place ‘X3-SC2’ (Storage Controller 2).

This order ensures that the heavier components are at the bottom for stability and likely follows Dell’s official guidelines for proper airflow and cable management within the rack1.

=========================

When the NVRAM status LED on an XtremIO X2 is flashing red at one-second intervals, it indicates an uncorrectable error. This is a critical status that typically signifies a hardware malfunction or failure within the NVRAM module, which requires immediate attention.NVRAM, or Non-Volatile Random Access Memory, is crucial for retaining data integrity during power losses or system crashes1.

The steps to address this issue usually involve:

Investigating the system logs to identify the specific nature of the error.

Contacting Dell EMC support for guidance on diagnosing and resolving the issue.

Following the recommended procedures for troubleshooting or replacing the affected NVRAM module, as per the support team’s instructions.

It is important to resolve such errors promptly to prevent potential data loss and to maintain the overall health and performance of the storage system1.

=========================

In an XtremIO X1 system, a full data protection group (DPG) can tolerate the loss of up to 5 drives before a data loss occurs. The XtremIO architecture ensures high availability andredundancy, but losing more than 5 drives within a DPG exceeds the system's ability to protect data, leading to potential data loss.
