EMC Dell XtremIO Deploy Achievement Sample Questions (Q47-Q52):

NEW QUESTION # 47
A systems administrator is installing a new Microsoft Windows 2012 host and has granted access to a 2 TB LUN from XtremIO. Quick formatting of the XtremIO LUN takes much longer than expected.
What is causing this delay in the formatting process?

  • A. LBA Block size is set to 4 kB
  • B. VAAI is disabled
  • C. UNMAP is enabled
  • D. UNMAP is disabled

Answer: C

Explanation:
The delay in the quick formatting process of a 2 TB LUN from an XtremIO storage array when installing a new Microsoft Windows 2012 host is likely caused by the UNMAP feature being enabled. The UNMAP command is part of the SCSI thin provisioning set, which allows the host to inform the storage array which blocks are no longer in use and can be reclaimed. When UNMAP is enabled, the quick format process may take longer because the storage array needs to process these UNMAP commands and perform the necessary space reclamation tasks1.
It's important to note that while UNMAP can improve storage efficiency, it can also introduce overhead during operations like formatting, which can lead to delays. For detailed procedures and best practices, it is recommended to consult the Official Dell XtremIO Deploy Achievement document or reach out to Dell support for the most accurate guidance.


NEW QUESTION # 48
What is an accurate statement when managing multiple XtremIO X2 clusters?

  • A. Virtual XMS can manage up to four X-Brick clusters
  • B. One XMS can manage up to 16 X-Brick clusters
  • C. Clusters can only be added/removed through the XMCLI
  • D. XtremIO X1 XMS can manage XtremIO X2 clusters

Answer: B

Explanation:
When managing multiple XtremIO X2 clusters, the XtremIO Management Server (XMS) is designed to manage multiple clusters efficiently. According to the Official Dell XtremIO Deploy Achievement document, one XMS can manage up to 16 X-Brick clusters. This capability is part of the XMS's design to provide centralized management and monitoring for large-scale deployments, allowing administrators to manage a significant number of clusters from a single interface1.
The XMS provides a comprehensive set of management features, including performance monitoring, alerting, reporting, and configuration management for all connected XtremIO clusters. It simplifies the administration of multiple clusters by providing a unified view and control over the entire XtremIO environment1.


NEW QUESTION # 49
Which Linux/UNIX command is used for monitoring the performance of system input/output devices?

  • A. netstat
  • B. nbtstat
  • C. iostat
  • D. stat

Answer: C

Explanation:
The iostat command is used for monitoring the performance of system input/output devices on Linux/UNIX systems. It provides statistics about disk input/output operations and CPU utilization, which are essential for assessing the performance of these devices. The iostat command generates reports that can be used to change system configuration to better balance the input/output load between physical disks1. This command is particularly useful for system administrators who need to monitor and optimize disk performance and throughput2.


NEW QUESTION # 50

Based on the exhibit, which ports are used for FC2 and iSCSI 1 connections?

  • A. b and d
  • B. a and c
  • C. b and c
  • D. a and d

Answer: B

NEW QUESTION # 51
When using the Microsoft VSS Framework with an XtremlO cluster to manage snapshot backups, what is the correct sequence of steps to create a Windows volume backup?

Answer:

Explanation:

Explanation:

The correct sequence of steps to create a Windows volume backup using the Microsoft VSS Framework with an XtremIO cluster is as follows:
* Requestor interacts with the VSS service to start the backup.
* VSS service sends a Freeze request to the Writer.
* Provider creates an XVC of the file system and exposes the volume to the host.
* VSS service sends a Thaw request to the Writer.
* Requestor uses the XVC to back up the content of the volume.
* The Requestor, typically a backup application, initiates the process by interacting with Microsoft's Volume Shadow Copy Service (VSS) to commence a snapshot backup.
* The VSS service then issues a Freeze request to its Writers, which are responsible for ensuring data consistency for applications during backups.
* An XtremIO Provider, which interfaces between the XtremIO storage and VSS, creates an XtremIO Virtual Copy (XVC) of the file system. This copy is then made accessible to the host system for backup purposes.
* After the XVC is created, the VSS sends a Thaw request to the Writers, allowing them to resume normal operations while maintaining data integrity.
* Finally, the Requestor uses the XVC to back up the content of the volume, ensuring a consistent and recoverable backup is made.
Please note that this sequence is based on the standard operation of Microsoft VSS with storage systems like XtremIO and should be verified against the most current Dell XtremIO Deploy Achievement documentation for any updates or specific instructions related to your environment.
