   A storage administrator is configuring host access to a PowerMax array. The environment has two separate fabrics, each with a single director. The administrator must ensure that a new AIX host can see both paths to the same LUN, but the host's HBA only has one WWN per port. The host will be connected to both fabrics. What is the minimum configuration required to provide redundant, zoned access?

   • AConfigure the host HBA to present a different WWN for each fabric using NPIV, then zone each WWN to a single director.
   • BCreate a single storage group, add the host's WWN to the masking view, and zone the WWN to one port on each of the two directors.
   • CCreate two separate storage groups, one for each fabric, and add the host's WWN to both masking views.
   • DZone the host's WWN to a single port on one director and rely on the array's internal failover to provide redundancy.

   A PowerMax administrator is investigating a connectivity issue. A new host has been zoned to a front-end port, and the masking view has been created. However, the host cannot see the LUN. The administrator checks the port and sees that the 'Logged In' indicator is 'No'. What is the most likely cause?

   • AThe host's HBA is not successfully logging into the fabric.
   • BThe port is not in the correct port group.
   • CThe masking view is incorrect.
   • DThe port speed is mismatched.

   A PowerMax administrator is troubleshooting a performance issue. A front-end FC port is showing a high 'percentage of time busy' in Unisphere. The port is connected to a heavily used database server. What is the most likely cause of this high utilization?

   • AThe back-end disk group is too slow.
   • BThe port is configured with the wrong topology.
   • CThe database workload is generating more I/O than the single port can handle.
   • DThe port's WWN is incorrect.

   An administrator is configuring a new PowerMax array. The array will be used for a VMware environment that uses iSCSI for storage connectivity. The administrator needs to configure the front-end ports for iSCSI. What is a required parameter that must be set for these ports?

   • AThe port's physical address in the director's back-end bus.
   • BThe World Wide Name (WWN) for the iSCSI port.
   • CThe Fibre Channel topology (e.g., point-to-point or arbitrated loop).
   • DThe IP address, subnet mask, and gateway for the iSCSI port.
