   An organization is deploying a new E-Series array and connecting it to a VMware ESXi host. The storage administrator wants to use the native VMware multipathing feature to manage the paths. What must the administrator do to ensure the E-Series paths are properly managed by VMware?

   • AInstall the NetApp E-Series DSM plugin for VMware and configure the path selection policy to 'Round Robin'.
   • BUse the default VMware NMP with the 'Fixed' path selection policy and manually set the preferred path.
   • CConfigure the E-Series array as 'Active/Passive' in the SANtricity software to match VMware's default settings.
   • DDisable the VMware NMP and use the E-Series SANtricity multipath driver for all path management.

   A database administrator reports intermittent performance degradation on a Linux host connected to an E-Series array. The multipath configuration shows all four paths as 'active' but the I/O throughput is inconsistent. The administrator suspects a path is flapping. What is the most effective way to confirm this diagnosis?

   • AReplace the Fibre Channel cables to rule out a physical layer issue.
   • BReview the system logs for 'multipathd' messages that indicate path failures or recoveries.
   • CCheck the output of 'multipath -ll' repeatedly over a few minutes and look for paths changing between 'active' and 'failed'.
   • DIncrease the 'polling_interval' in '/etc/multipath.conf' to reduce the frequency of path checks.

   A storage administrator is troubleshooting a multipathing issue on a Windows host. The 'mpclaim -s -d' output shows that two of the four paths are in a 'Failed' state. The administrator has verified that the cables, HBAs, and switch ports are all functional. What should the administrator check next?

   • AReboot the Windows host to re-initialize the MPIO stack.
   • BVerify that the E-Series array's target ports are online and not disabled.
   • CChange the load balance policy to 'Failover Only' to mask the failed paths.
   • DReinstall the HBA drivers on the Windows host.
