Q27. A storage administrator is configuring SAN switches and zoning to connect a four X-Brick XtremlO array. A VMware ESXi server is hosted on a blade chassis with 16 HBA ports.
In addition, the SAN consists of two separate SAN switches.
What is the recommended XtremlO best practice for zoning?

First Storage Controllers’ HBA ports to the first switch
Second Storage Controllers’ HBA ports to the second switch
Multipath all host ports to single LUNs per zone

Two HBA connections per host
Single initiator/multiple targets per zone
Maximum of 16 paths for each device
Host connected to each SAN switch

Single Storage Controller HBA port to the first switch
Single Storage Controller HBA port to the second switch
Single initiator/multiple targets per zone
Maximum of 4 paths for each LUN per zone

Two HBA connections per host connected to a single switch
Multiple initiators/multiple targets per zone
Maximum of 4 paths for each LUN per zone

Q28. You need to design a VDI solution for a customer. Which recommended best practices should be used for VDI environments?

Align data on 8 kB boundariesPut all VDI-related data on one large LUN

Align data on 4 kB boundariesAllocate multiple XtremIO LUNs to each host

Align data on 4 kB boundariesPut persona and user data on XtremIO LUNs

Align data on 8 kB boundariesPut the master VM image on an XtremIO LUN

When designing a Virtual Desktop Infrastructure (VDI) solution, it’s important to consider the best practices for performance and efficiency.
Option OB, “Align data on 4 kB boundariesAllocate multiple XtremIO LUNs to each host”, is a recommended best practice for VDI environments12.This is because aligning data on 4 kB boundaries can help to optimize the performance of the storage system12.The XtremIO storage array uses a 4 kB data block size, so aligning data on 4 kB boundaries can help to ensure that data is efficiently stored and retrieved12.
Allocating multiple XtremIO LUNs to each host can also help to distribute the I/O load more evenly across the storage system, which can improve performance12.This is particularly important in VDI environments, where there can be a high level of concurrent I/O activity12.
The other options, while they may be part of the overall process, are not specifically recommended for VDI environments:
* Option OA, “Align data on 8 kB boundariesPut all VDI-related data on one large LUN”, is not recommended because aligning data on 8 kB boundaries does not match the 4 kB data block size used by the XtremIO storage array12.Also, putting all VDI-related data on one large LUN can lead to performance issues due to the high level of concurrent I/O activity in VDI environments12.
* Option OC, “Align data on 4 kB boundariesPut persona and user data on XtremIO LUNs”, is not recommended because persona and user data typically do not require the high performance provided by XtremIO LUNs12.
* Option OD, “Align data on 8 kB boundariesPut the master VM image on an XtremIO LUN”, is not recommended because aligning data on 8 kB boundaries does not match the 4 kB data block size used by the XtremIO storage array12.
Therefore, the verified answer isB.Align data on 4 kB boundariesAllocate multiple XtremIO LUNs to each host, as it provides the most suitable solution for VDI environments according to the Dell XtremIO Design Achievement document12.

Q29. A user attempts to create a quorum disk for a host cluster. Volume parameters are:
Size = 1000 Kb
. Name 1 MB_Vol
However, the volume creation fails. What caused the process to fail?

Quorum disks cannot have an 8 kB block size

Volume name is invalid

Volume size is too small

XtremlO volumes cannot be quorum disks

Q30. When using the XtremIO PoC Toolkit, what is the purpose of the Age phase?

Test the performance of the All-Flash array with non-production static data

Overwrite each LUN multiple times to ensure they contain all unique data

Continuously write to a specific range of logical block addresses to test Flash durability

Scatter writes across the entire array to simulate ordinary use of the system

Q31. What is the correct sequence of steps to perform a UNMAP operation on a VMware ESXi host that is mapped to an XtremlO volume containing very little data and the XtremIO array shows the space in use?
