What is causing the connectivity loss during failover?
An engineer is performing failover testing on an FC-attached, dual-controller SC8000 system. The engineer
notes that the customer’s Windows 2008 R2 servers experience I/O errors. The RHEL and ESX servers
experience no problems.
A11 FC HBA timeouts are configured per Dell best practices. The Windows servers that are experiencing
issues have had no OS-level configuration changes related to SAN storage. All servers use the same FC fabric.

Which ESX Multi-pathing policy should be used?
A customer has mapped a volume to a ESX server using two 8 Gb Fibre Channel (FC) paths. The customer
needs the traffic to split equally across the two FC paths.
Which ESX Multi-pathing policy should be used?
Which HBA feature must be enabled to meet the requirement?
An engineer needs to configure a server. The server is connected to a Storage Center via iSCSI using or more
hardware iSCSI host bus adapters. If connectivity is lost due to controller failover, the server needs to reconnect
to the Storage Center iSCSI target ports.
Which HBA feature must be enabled to meet the requirement?
Which feature is enabled?
An engineer needs to configure a VMware host. According to best practice, the engineer needs to enable a
feature by changing the variables QFullSampleSize and QFullThreshold. The engineer sets those two
parameters to the value of 0 in VMware ESXi 5.1 Patch 1 and later versions.

An engineer has mapped a volume to an existing Windows 2012 server. The engineer has configured zoning
and confirmed that all paths are correctly configured. The operating system can only see one path within the
MPIO software.
Which step should the engineer take so that all paths are presented to the server?
