   • BThe multipath configuration file is missing
   • CThe LUN is not mapped to the host

   A Linux administrator is configuring multipathing for an E-Series array. The administrator has edited '/etc/multipath.conf' to add the E-Series device configuration and has run 'multipath -r' to reload the configuration. However, 'multipath -ll' shows the device as a single path instead of a multipath device. What is the most likely cause?

   • AThe Fibre Channel HBAs are not properly zoned to the E-Series array.
   • BThe 'wwid' in the multipath.conf file does not match the actual WWID of the E-Series LUN.
   • CThe E-Series array is configured as 'Active/Passive', which prevents multipathing.
   • DThe 'multipathd' service is not running, so the configuration was not applied.

   A company is standardizing its SAN environment on E-Series storage. The hosts are a mix of Windows Server 2019, RHEL 8, and VMware ESXi 7. The storage team wants to use the native multipathing software on each OS to minimize licensing costs. Which statement accurately describes the multipathing approach for these hosts?

   • AWindows uses MPIO, Linux uses Device Mapper Multipath (DM-Multipath), and VMware uses NMP, all of which are native and supported with E-Series.
   • BAll three operating systems must use the NetApp E-Series SANtricity multipath driver for proper failover.
   • CWindows and Linux can use native multipathing, but VMware requires a third-party DSM to function at all.
   • DLinux and VMware can use native multipathing, but Windows requires the installation of a third-party DSM from NetApp.

   What is the role of host-side multipathing software?

   • ATo manage the physical disks inside the storage array
   • BTo present LUNs to the host operating system
   • CTo provide a graphical interface for SAN switch configuration
