A.

port-based zoning

B.

zoning is optional

C.

single HBA zoning (one HBA per zone)

D.

single operation system zoning (all HBAs from one OS in a zone)

Question 2
Single choice

A customer has identified a performance bottleneck with Online Transaction Processing (OLTP) production host LUNs. The performance improvement plan includes a change to the Hitachi Dynamic Link Manager load balancing algorithm which is currently set to Round Robin.

Which setting would you recommend?

A.

Least I/Os

B.

Least blocks

C.

Extended Round Robin

D.

Extended Least blocks

Question 3
Single choice

You have just allocated four 3TB LUNs from a Hitachi Unified Storage System to a set of ESX 4.x servers.
The VMware administrator can see volumes that are assigned to the servers from an older storage array, but not the volumes you have just allocated.

What is the most likely cause?

A.

The FC switch ports need to be disabled/enabled to force the HBAs to re-login to the fabric.

B.

This a newer storage array with an older version of ESX so the HBA drivers need to be updated.

C.

ESX 4.x servers cannot recognize volumes that are 2TB or larger.

D.

The rescan function in VMware is not working, so both servers need to be rebooted.

Question 4
Multiple choice

Question 5
Multiple choice

A customer wants to create a multi-path environment for a specific Redhat Linux application on a Hitachi Unified Storage system. They have created Host Groups on all of the available ports and mapped the logical units accordingly.

A.

Device Mapper

B.

Multipath I/O (MPIO)

C.

Hitachi Dynamic Link Manager

D.

Multiplexed I/O (MPxIO)

Question 6
