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

A Continuously write to a specific range of logical block addresses to test Flash durability
B Overwrite each LUN multiple times to ensure they contain all unique data
C Test the performance of the All-Flash array with non-production static data
D Scatter writes across the entire array to simulate ordinary use of the system

How should a storage administrator navigate to different XtremIO clusters from the XMS GUI if the administrator has more than one cluster managed by the same
XMS?

A Click the Cluster Name on the Menu bar near the top of the screen
B Click the Inventory List button on the Menu bar
C Click the Administration tab and locate the Cluster Name
D Click the Cluster Name on the Status bar at the bottom of the screen

A customer has a large ESX server environment they are considering deploying to XtremIO for a VDI implementation. To determine a baseline of the environment, you are proceeding with documenting each servers CPU, NIC, and disk utilization statistics. The customer has provided you with direct CLI access to the servers to conduct this assessment.
Which utility should be used to monitor these performance parameters?

A esxtop
B resxtop
C top
D iostat

A customer has recently purchased an XtremIO 10 TB single X-Brick cluster for an implementation of Oracle RAC. The customer wants your help with integrating
Oracle with their new XtremIO cluster. The customer has three DATA disk groups, two REDO disk groups, and four FRA disk groups.
How many XtremIO LUNs should be assigned to the FRA disk groups?

A 2
B 4
C 6
D 8

Which multipathing software is supported by XtremIO?

A PowerPath/VE and NMP on ESXi hosts
B MPIO on non-clustered Microsoft Windows hosts only
C PowerPath/VE on Microsoft Windows VMs hosted by ESXi
D Native MPIO on IBM AIX clusters

Based on best practice, what is the maximum number of paths a host should have to an XtremIO volume?

A 4
B 8
C 16
D 32

A new 500 GB VM disk is created on a database that resides on an XtremIO LUN. The VMware administrator plans to provision the disk using the thick provisioned eager zeroed format.
How much physical XtremIO capacity will be allocated during this process?

A 5 GB
B 10 GB
C 50 GB
D None D

A customer wants to purchase an XtremIO array. After the array is installed, the customer wants to initially disable encryption. What is the result of enabling encryption on an array that is already being used?

A Data will remain in place but the XtremIO cluster services will need to be temporarily shutdown.
B Data will remain in place and there will be no interruption to the XtremIO cluster services.
C Data will be erased but there will be no interruption to the XtremIO cluster services.
D Data will be erased and the XtremIO cluster services will be temporarily shutdown.

An XtremIO administrator is having a problem with performance and is troubleshooting the issue. What is an accurate statement about I/O transfers?

A As I/O size increases, IOPs increase, and latency increases
B As I/O size increases, IOPs decrease, and bandwidth increases
C As I/O size decreases, IOPs increase, and bandwidth increases
D As I/O size decreases, IOPs decrease, and latency increases A

You are designing an XtremIO solution for a potential customer. If the server and storage information is available, which information should be documented regarding the customers capacity expectations?

A Capacity requirements on a per data center basis Expandability/scalability Performance requirements determined on a server-to-server basis
B Capacity requirements on a per volume basis Expandability/scalability Performance requirements determined on a server-to-server basis
C Capacity requirements on a per volume basis Compression rates/scalability Performance requirements determined on a server-to-server basis
D Capacity requirements on a per data center basis Expandability/scalability Performance requirements determined holistically

A customer has purchased a two X-Brick XtremIO array with a physical XtremIO Management Server (XMS). The customer plans to use all Fibre Channel connectivity in the environment.
What are the physical connectivity requirements for the cluster?

A 1 Copper Ethernet connection, 4 Fibre Channel Optical connections
B 3 Copper Ethernet connections, 8 Fibre Channel Optical connections
C 4 Copper Ethernet connections, 16 Fibre Channel Optical connections
D 5 Copper Ethernet connections, 8 Fibre Channel Optical connections

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

A 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
B Connect a single storage controller to the first switch Connect a second storage controller to the second switch Single initiator/multiple targets per zone Maximum of 6 paths for each LUN per zone
C Connect all N1 storage controllers to the first switch Connect N2 storage controllers to the second switch Multipath all host ports to single LUNs per zone Maximum of 4 paths for each LUN per zone
D Multiple HBA connections per host Single initiator/single target per zone Maximum of 2 paths to each X-Brick for each initiator Each host connected to each SAN switch

Based on XtremIO Data Protection, how many dedicated hot spare disks per X-Brick are required?

A 0
B 1
C 2
D 3
