Hitachi HITACHI DATA SYSTEMS CERTIFIED SPECIALIST -NAS ARCHITECT Sample Questions:

1. An enterprise customer has asked you to plan a data migration from their six existing Windows Storage Server clusters to their Hitachi NAS platform 4000 cluster. They are currently using DFS and all of the current user access is mapped to the DFS namespace. You are asked to deliver a transparent migration strategy to minimize user impact.
Which optimal migration strategy do you recommend?

A) Use Cluster Name Space and build a namespace that mirrors the current DFS namespace.
B) Create an EVS for each server instance and assume the original name and IP address.
C) Use CNAME records to point end-users to EVS instances using the same UNC path.
D) Consolidate the environment to two EVS, migrate the shares and link them to the same DFS context.

2. You are designing Hitachi NAS File Clone solution for a customer with an existing Hitachi NAS platform.
Which two are required? (Choose two.)

A) iSCSI volumes
B) Hitachi NAS G2 hardware
C) NAS firmware version 8.x or later
D) WFS-2 file system

3. A customer wants to implement a Hitachi NAS Platform 4000 in a 10 GbE network environment with some 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 number of modules (blades) in a switch
B) the use of flow control
C) the use of a Network File System
D) the number of network hops

4. A customer is running Web messaging related applications using a Hitachi NAS Platform 4000. They are worried about data inconsistencies and would like to know how a WFS-2 file system can benefit their current environment.
Which two functions will provide an additional layer of data protection? (Choose two.)

A) Perform a quick rollback to a previous successful snapshot.
B) Execute the "consistency-check" command.
C) Perform data recovery from the deleted file system.
D) Use multiple checkpoints.

5. Your customer would like to implement a two-node Hitachi NAS Platform 4000 cluster
using a HUS 110 storage system. The HUS is shared with other Open Systems platforms. Ports OB and 1B are the only ports available on the HUS. Hport 1 and 3 are the only ports available on the Hitachi NAS Platform nodes.
Which two wiring and zoning configurations should be used? (Choose two.)

A) Hport 1 and 3 of node 1, and HUS port OB must be connected to switch 1 and could be in the same zone.
B) Hport 1 of both nodes, and HUS port OB must be connected to switch 1 and could be in the same zone.
C) Hport 3 of both nodes,and HUS port 1B must be connected to switch 2 and could be in the same zone.
D) Hport 1 and 3 of node 2, and HUS port 1B must be connected to switch 2 and could be in the same zone.
