EMC Dell XtremIO Operate Achievement Sample Questions (Q21-Q26):

NEW QUESTION # 21
A systems administrator upgraded a Microsoft Windows 2003 server to Windows Server 2008. The administrator noticed that performance is less than expected. Investigationhas shown that the partitions on the XtremlO volumes are misaligned.
Which step(s) should be taken to align the data?

A. Backup the data, run diskpart, recreate the partition, restore the data
B. Use Disk Management to move the partition
C. Use Mbralign to move the partition
D. Backup the data, run fdisk, recreate the partition, restore the data

Answer: A

Explanation:
When dealing with misaligned partitions on XtremIO volumes after upgrading from Windows Server 2003 to Windows Server 2008, the following steps should be taken to realign the data:
* Backup the Data: The first and most crucial step is to ensure that all data on the existing partitions is backed up. This is to prevent any data loss during the alignment process.
* Run Diskpart: After backing up, use the Diskpart utility, which is a command-line disk partitioning tool that allows you to manage your disk's partitions.
* Recreate the Partition: With Diskpart, delete the existing misaligned partition and then create a new partition.When creating the new partition, ensure that it is aligned correctly, typically to a 1MB boundary, which is the default alignment for Windows Server 2008 and newer versions1.
* Restore the Data: Once the new partition is created and aligned properly, restore the data from the backup to the newly aligned partition.
This process ensures that the partitions are aligned optimally for the XtremIO storage system, which can help improve performance and efficiency. It's important to note that while tools like Disk Management and Mbralign can be used for managing partitions, they may not provide thenecessary functionality to realign existing partitions on Windows Server 2008.Therefore, using Diskpart is the recommended approach1.

NEW QUESTION # 22
What is a specific configuration guideline that should be followed when configuring Linux hosts to support XtremIO storage?

A. Enable the I/O elevator
B. Set the execution throttle to 35025
C. Set the LUN queue depth to 64
D. Assign LUN 0 to the boot LUN

Answer: C

Explanation:
* Configuring Linux hosts to support XtremIO storage involves setting the LUN queue depth to 64.
* This configuration ensures optimal performance by allowing the host to handle multiple I/O operations concurrently, matching the capabilities of the XtremIO array.
* Proper tuning of the LUN queue depth is crucial for maximizing throughput and minimizing latency in high-performance storage environments.

NEW QUESTION # 23
If a host writes a unique data block to an XtremlO X1 array, what is the correct sequence of operations?

Answer:

Explanation:

The correct sequence of operations when a host writes a unique data block to an XtremIO X1 array is as follows:
* Data is arranged into 8 KB blocks and fingerprinted.
* Fingerprint to the physical array location mapping is created.
* Location for the block on the array is selected.
* Write operation is performed.
* Reference count for the fingerprint is set to "1".
* Data Arrangement and Fingerprinting: Initially, the data received from the host is organized into 8 KB blocks.Each block is then fingerprinted, which involves creating a unique identifier for the data block that can be used to detect duplicates and manage data more efficiently1.
* Mapping Creation: After fingerprinting, a mapping between the fingerprint and its physical location on the XtremIO array is established.This step is crucial for the array to know where each data block is stored and to retrieve it quickly when needed1.
* Location Selection: The XtremIO system then selects the most appropriate location for the data block on the array.This decision is based on various factors, including space availability and optimization algorithms1.
* Write Operation: Once the location is determined, the actual write operation takes place.The data block is written to the selected spot on the SSD within the array1.
* Reference Count Setting: Finally, a reference count for the data block's fingerprint is set to "1". This indicates that there is currently one instance of this data block stored on the array.The reference count is used to manage data deduplication and ensure efficient storage utilization1.

NEW QUESTION # 24
In order to upgrade an XtremlO X2 two X-Brick cluster with 30 SSDs per DAE, what is the minimal number of SSDs that can be ordered?

A. 0
B. 1
C. 2
D. 3

Answer: D

Explanation:
* According to Dell XtremIO documentation, when upgrading an XtremIO X2 two X-Brick cluster, the minimal number of SSDs that can be ordered is 12.
* XtremIO clusters use a scale-out architecture, and each X-Brick requires a specific number of SSDs for proper functioning.
* The upgrade process is designed to maintain the performance and resilience of the storage system.
* The specific requirement of 12 SSDs ensures balanced data distribution and optimal performance across the cluster.

NEW QUESTION # 25
What is an accurate statement regarding RecoverPoint and XtremIO?

A. RecoverPoint cannot scale-up with X-Bricks by adding more RPAs
B. RecoverPoint only supports homogeneous replication from XtremIO-to-XtremIO
C. RecoverPoint supports synchronous and asynchronous replication of file-based storage
D. At least one RecoverPoint Appliance is required per X-Brick

Answer: D

Explanation:
* Each X-Brick in an XtremIO environment requires at least one RecoverPoint Appliance (RPA) to manage replication tasks effectively.
* RecoverPoint provides both synchronous and asynchronous replication, ensuring data integrity and disaster recovery capabilities.
* The RPA is crucial for handling replication operations and maintaining data consistency across XtremIO clusters.
