EMC Dell XtremIO Operate Achievement Sample Questions (Q59-Q64):

NEW QUESTION # 59
What is the maximum number of volumes allowed in an XtremIO Consistency Group?

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

Answer: A

Explanation:
* The maximum number of volumes allowed in an XtremIO Consistency Group is 512.
* Consistency Groups ensure that multiple volumes can be managed and replicated together, maintaining data consistency across all included volumes.
* This limit allows for efficient management and scalability of storage resources within the XtremIO environment.

* XtremIO Consistency Group Best Practices

NEW QUESTION # 60
What is a specific configuration guideline that should be followed when configuring Linux hosts to support XtremIO storage?

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

Answer: D

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.

* Dell XtremIO Host Configuration Guide for Linux
* Host Configurations in XtremIO Environments

NEW QUESTION # 61
What is the purpose of Microsoft VSS integration with XtremlO?

A. Directly transfer data between storage devices
B. Allow third-party management of volume operations
C. Compress files before presenting to LUNs
D. Reclaim space from deleted volumes

Answer: B

Explanation:
* The purpose of Microsoft VSS (Volume Shadow Copy Service) integration with XtremIO is to allow third-party management of volume operations.
* VSS provides a framework that enables applications to create consistent snapshots, backups, and restores of data without disrupting operations.
* This integration is essential for ensuring data integrity and consistency during backup and restore operations.

* Dell XtremIO VSS Integration Guide
* Microsoft VSS Documentation

NEW QUESTION # 62
Which file systems support UNMAP on a Linux server connected to an XtremlO cluster?

A. Ext4, XFS, and ZFS
B. ReiserFS, Ext3, and XFS
C. Ext3, Ext4, and XFS
D. ReiserFS, Ext4, and ZFS

Answer: C

Explanation:
For Linux servers connected to an XtremIO cluster, the file systems that support the UNMAP command include Ext3, Ext4, and XFS. The UNMAP command allows these file systems to inform the storage array about blocks that are no longer in use, facilitating better space reclamation and efficiency in storage management.
References:
* Dell EMC documentation on XtremIO configurations for Linux environments confirms the support for UNMAP with these specific file systems.
* Linux kernel documentation also supports the use of UNMAP/TRIM operations with Ext3, Ext4, and XFS for storage optimization.

NEW QUESTION # 63

Which operation is represented in the exhibit?

A. Write-back Cache
B. Read Cache Hit
C. Read Cache Miss
D. Write-through Cache

Answer: C

Explanation:
If the requested data is not found in cache, it is called a cache miss and the data must be read from the storage.
The back end accesses the appropriate storage device and retrieves the requested data. Data is then placed in cache and finally sent to the compute system through the front end. Cache misses increase the I/O response time.
