Hitachi Data Systems Storage Architect-Hitachi NAS Platform (HH0-450) Free Practice Test

Question 1

A customer wants to consolidate four Windows servers into one Hitachi NAS Platform 2-node 3090 cluster. Due to security requirements, each server's data has to be kept on a separate file system and the workload changes from month to month. Either DNS names or IP addresses are used for mapping the shares. The customer wants to take advantage of balancing the load between the two nodes in the cluster. Which consolidation method should be used?

A. Create two EVSs and use DNS aliasing to represent the four names and four IP addresses.

B. Create four individual EVSs, two on each node and use QoS to balance the load.

C. Create four individual EVSs representing the four servers.

D. Create two EVSs, add two names and two IP addresses to every EVS.

Correct Answer: C

Question 2

A customer recently purchased a Hitachi NAS Platform 3090 and a Hitachi AMS2300 for back-end storage. The customer is concerned about back-end performance. What are two considerations? (Choose two.)

A. Do not mix SAS and SATA in the same storage pool.

B. Do not use Brocade M-Series switches.

C. Do not exceed 8 SATA LUNS per FC port.

D. Do not share storage ports with another other host.

Correct Answer: A,D

Question 3

When de-migrating files with Data Migrator from Tier 2 back to Tier 1 and there is insufficient space available for the de-migration path, what happens to the de-migration instance?

A. Data Migrator will fail the reverse migration instance.

B. Data Migrator will look for an alternate location with available space.

C. Data Migrator will automatically map to another file system.

D. Data Migrator will automatically delete data in place of the stub.

Correct Answer: A

Question 4

A customer has a Hitachi AMS2100 attached to a 2-node Hitachi NAS Platform 3090 cluster. They initially purchased 15 TB and have just purchased an additional 5 TB. They now need to expand their existing storage pools. What must be considered when expanding the storage pools?

A. All storage pools must be offline.

B. All system drives must be in the same system drive group.

C. All system drives must be offline.

D. All system drives must be of the same size in terms of capacity.

Correct Answer: D

Question 5

An enterprise customer has asked you to plan a data migration from their six existing Windows Storage Server clusters to their Hitachi NAS platform 3090 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. Consolidate the environment to two EVSs, migrate the shares and link them to the same DFS context.

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. Use Cluster Name Space and build a namespace that mirrors the current DFS namespace.

Correct Answer: A

Question 6

You are designing a Hitachi NAS Platform solution for a video streaming application over NFS version 3. The I/O profile is heavily read intensive. Which Hitachi NAS Platform feature would deliver optimum performance?

A. superflush

B. Transfer Primary Access

C. NFS acceleration

D. read cache

Correct Answer: D
