Which benefit does multipathing provide in a SAN environment?

It eliminates the need for backup software

It increases the maximum LUN size supported by the storage array

It allows a single HBA to connect to multiple storage arrays without additional configuration

It provides automatic failover in the event of a path failure

What is the primary purpose of multipathing in a SAN environment?

To increase the storage capacity available to a host by combining multiple LUNs

To allow multiple hosts to access the same LUN simultaneously without any configuration

To provide redundant I/O paths between the host and storage, enabling failover and load balancing

To encrypt data in transit between the host and the storage array

A storage administrator has just finished configuring multipathing on a Windows host connected to an E-Series array. The administrator wants to perform a quick verification that the configuration is working before putting the host into production. Which action is the most appropriate for this verification?

Run a disk performance test to see if the throughput is acceptable.

Use 'mpclaim -s -d' to confirm that all paths are listed as 'Active'.

Reboot the host and check if the disks are visible after the reboot.

Check the SANtricity System Manager to confirm the host is connected.

After configuring multipathing on a Windows host connected to an E-Series array, the administrator wants to verify that all four paths are active and that the configuration is working correctly. Which action should the administrator take to confirm the multipath configuration?

Use the 'mpclaim -s -d' command to display the path status for each disk.

Open 'MPIO' in the Control Panel and check the 'DSM' tab to see the list of devices using MPIO.

Check the Windows Event Viewer for any MPIO-related warnings or errors.

Run 'diskpart' and select the volume to see the associated paths.

A storage administrator has configured multipathing on a Windows host connected to an E-Series array. After a firmware upgrade on the array, the administrator notices that the 'mpclaim -s -d' output shows all paths as 'Unavailable'. What is the most likely cause of this issue?

The firmware upgrade changed the device identification, causing the MPIO DSM to no longer recognize the device.

The multipath configuration was reset to defaults during the firmware upgrade.

The firmware upgrade disabled the Fibre Channel ports on the array, requiring a reboot of the array.

The Windows host lost its HBA drivers during the upgrade and needs a driver reinstall.
