Whenever our team identifies changes in the exam questions,exam objectives, exam focus areas or in exam requirements, We immediately update our exam questions for both PDF and online practice exams. This commitment ensures our customers always have access to the most current and accurate questions. By preparing with these actual questions, our customers can successfully pass the Dell EMC Dell XtremIO Operate Achievement exam on their first attempt without needing additional materials or study guides.
Other certification materials providers often include outdated or removed questions by Dell EMC in their Dell EMC D-XTR-OE-A-24 exam. These outdated questions lead to customers failing their Dell EMC Dell XtremIO Operate Achievement exam. In contrast, we ensure our questions bank includes only precise and up-to-date questions, guaranteeing their presence in your actual exam. Our main priority is your success in the Dell EMC D-XTR-OE-A-24 exam, not profiting from selling obsolete exam questions in PDF or Online Practice Test.
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?
VMware vStorage APIs for Array Integration (VAAI) offloads certain storage tasks from the ESXi host to the storage array.
When VAAI is disabled, operations like quick formatting can take significantly longer because the tasks are handled by the host instead of being offloaded to the array.
Quick formatting involves writing zeroes to the entire LUN, and without VAAI, this process is much slower.
Enabling VAAI allows the XtremIO array to handle these operations more efficiently, reducing the time required for tasks like formatting.

In addition to PowerPath, what other supported multipathing software is used for VMware ESXi hosts connecting to XtremIO?
In addition to PowerPath, the supported multipathing software for VMware ESXi hosts connecting to XtremIO is Native Multipathing (NMP).
NMP is integrated with VMware and provides basic multipathing capabilities, allowing for path redundancy and load balancing.
Properly configuring multipathing is crucial for achieving high availability and optimal performance in a VMware environment with XtremIO storage.

A systems administrator's VMware Horizon environment consists of 1000 linked clones. Based on best practices, what is the minimum number of datastores required to support this configuration connected to XtremIO?
Minimum 4 Datastores: Based on best practices for VMware Horizon environments, with 1000 linked clones, it is recommended to have a minimum of 4 datastores connected to XtremIO.
This configuration helps distribute the load and ensures optimal performance and manageability.

A systems administrator has been informed that a new backup policy has been put in place for 500 production volumes on an XtremlO X2-R array. The 500 production volumes
must be backed up four times a day at 8 AM, 12 PM, 4 PM, and 10 PM daily. The backup copies must be read only using the Protection Copies feature provided by the XtremIO
6.x code.
How many days of XtremlO Virtual Copy read only volumes can the array store before the original backups are deleted?
7 Days: Given that 500 production volumes must be backed up four times a day using XtremIO's Protection Copies feature, the system can store the read-only volumes for approximately 7 days before the oldest backups are deleted.
This calculation ensures that the array's capacity is used efficiently while adhering to the backup policy requirements.

A systems administrator is responsible for the operations of 20 XtremlO X1 clusters; each are using a standalone XMS server. The administrator wants to consolidate management operations to the minimum number of XMS servers as possible.
What is the smallest number of XMS servers that can support the environment?
A single XtremIO Management Server (XMS) can manage up to 8 X-Brick clusters.
For 20 XtremIO X1 clusters, the smallest number of XMS servers required to support the environment is 4.
Consolidating management operations to the minimum number of XMS servers helps in simplifying administration and monitoring tasks.
