  B. Use the changed directory list option.

  C. Migrate the admin EVS to the node replicating the data.

  D. Create an additional IP address on the source EVS.

  Correct Answer: B

  B. File Replication

  C. Hitachi Shadowlmage

  D. Hitachi Universal Replicator

  Correct Answer: BD

• Question 48:

  A customer would like to implement an OLTP application using their Hitachi NAS Platform 4000. The Hitachi NAS Platform is connected to a Hitachi HUS 150 with SAS drives running firmware 0935/A or later. They want to achieve maximum performance. Considering the queue depth limitations on the Hitachi NAS Platform and Hitachi HUS 100 systems, what is the maximum number of active LUNs that should be assigned on each HUS target port?

  A. 16

  B. 32

  C. 64

  D. 128

  Correct Answer: B

• Question 49:

  1 GbE clients and they are asking about potential performance limiting factors in their network.

  Which two factors must be taken into consideration? (Choose two.)

  A. the use of a Network File System

  B. the use of flow control

  C. the number of modules (blades) in a switch

  D. the number of network hops

  Correct Answer: BD

• Question 50:

  A customer would like to implement a Hitachi NAS Platform in a NFS environment. They have two business requirements:

  1.

  The "Dev" environment has a write intensive random workload and requires excellent performance.

  2.

  The "Eng" environment has a 80% read and 20% write random workload and requires a right balance

  between cost and performance.

  Which set of RAID group types should you choose?

  A. RAID-10forDevandRAID-6forEng

  B. RAID-5forDevandRAID-10forEng

  C. RAID-10forbothDevandEng

  D. RAID-10forDevandRAID-1forEng

  Correct Answer: A
