A customer requires a VSP asynchronous replication solution for their Hitachi NAS Platform 4000. They have two data centers that are over 500 km apart. They are concerned with intermittent network connectivity problems and would like to leverage disk-based journaling.
Which block-based replication should be used?

• A.Hitachi TrueCopy Extended Distance
• B.Hitachi TrueCopy
• C.Hitachi Universal Replicator
• D.Hitachi Shadowlmage

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.Perform data recovery from the deleted file system.
• C.Execute the "consistency-check" command.
• D.Use multiple checkpoints.

To increase resilience and maintain performance a customer wants to upgrade their Hitachi NAS Platform two-node cluster to a three-node cluster.
What are two prerequisites? (Choose two.)

• A.A NVRAM upgrade for mirroring must be performed.
• B.The 10 GbE cluster interconnect media must be single mode fiber.
• C.An additional cluster license is needed.
• D.10 GbE switches are required for the cluster interconnect.

You are designing a solution for a Hitachi NAS Platform 4000 that will be used in a VMware vSphere environment.The customer would like to use tiering to improve performance.
What are three design best practices for Hitachi Tiered File Systems in this environment? (Choose three.)

• A.Use the "fs-analyze-data-usage" command to simulate Tiered File System metadata requirements.
• B.When using SAS drives in tier 0, RAID 1+0 should be used.
• C.Use five percent of the total file system size to estimate the metadata requirements.
• D.SSD should be used in tier 0 to achieve the largest performance improvements.
• E.RAID6 should be configured for HDT.

You are designing a solution for a customer who has the following requirements for their NAS environment:
Synchronous replication for all their filesystems
Automated failover
Stretched cluster at a distance of 50 km
---
Which solution should you recommend?

• A.SyncDR
• B.Hitachi Universal Replicator
• C.Object Replication
• D.File Replication
