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.Multiple HBA connections per hostSingle initiator/single target per zoneMaximum of 2 paths to each X-Brick for each initiatorEach host connected to each SAN switch
• B.Connect a single storage controller to the first switchConnect a second storage controller to the second switchSingle initiator/multiple targets per zoneMaximum of 6 paths for each LUN per zone
• C.Connect all N1 storage controllers to the first switchConnect N2 storage controllers to the second switchMultipath all host ports to single LUNs per zoneMaximum of 4 paths for each LUN per zone
• D.Two HBA connections per host connected to a single switchMultiple initiators/multiple targets per zoneMaximum of 4 paths for each LUN per zone

At which point is data compressed when a host sends data to the XtremIO storage system?

• A.Inline before data is written to the SSD
• B.After data is written to the SSDs
• C.After data is in SSD cache
• D.Once data is written to the storage controller

A customer has recently deployed an XtremIO 20 TB two X-Brick cluster to run an existing instance of Oracle RAC previously leveraging VNX for back-end storage. The application environment uses a block size of 1 MB. Multiple tables are in use with the
PARALLEL_DEGREE_POLICY variable set to AUTO.
The customer wants your help with tuning the DB_FILE_MULTIBLOCK_READ_COUNT parameter for best performance with XtremIO. Which values should be recommended for tuning the DB_FILE_MULTIBLOCK_READ_COUNT parameter in the Oracle RAC
environment?

• A.24 or 32
• B.64 or 128
• C.256 or 512
• D.8 or 16

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

When installing a physical XtremIO Management Server (XMS) station, which requirement must be met?

• A.XMS must be able to access one of the management ports on one X-Brick storage controller in the cluster
• B.XMS must be able to access all management ports on the X-Brick storage controllers
• C.XMS must be able to access only the management ports on the first X-Brick's storage controllers
• D.XMS must be able to access all management ports on at least two X-Brick storage controllers in the cluster
