Your customer is interested in using thin provisioning at the file system level and wants to know how the auto-expansion function works on the Hitachi NAS Platform. Which two statements are true? (Choose two.)
A. A storage pool will automatically expand reaching the high watermark.
B. A thin file system will allocate space as needed until the maximum size is reached.
C. A thin file system will automatically expand to 10% beyond the high watermark.

You are asked to design a Hitachi NAS Platform solution with a requirement to replicate data across a distance of 300 km. Which two replication technologies are suitable? (Choose two.)
A. TrueCopy
B. Intelligent Data Replication
C. ShadowImage
D. Hitachi Universal Replicator
A customer has a single node Hitachi NAS Platform 3080 which is the only host directly attached to a Hitachi AMS2500. They would like to add another mission critical application to this environment and with the performance requirement of 12,000 IOPS with 80% random writes at 4 KB block sizes. The AMS is currently configured with 45 SATA drives in a RAID 6 configuration. The customer has stated three requirements: 1. the 3080 should continue to support data archiving. 2. the new mission critical application must be highly available. 3. they want to re-use the AMS2500. Which solution would you recommend?
A. Add a new Hitachi NAS Platform cluster and additional SAS drives in RAID 1+0.
B. Add a new Hitachi NAS Platform node and additional SATA drives in RAID 6.
C. Add a new Hitachi NAS Platform node and additional SATA drives in RAID 5.
D. Add an externalized AMS1000 with SSD drives.
The administrator of a production Hitachi NAS Platform connected to a Hitachi AMS2300 requires file level replication to another Hitachi NAS Platform. However, there is a concern over the large numbers of files and about the high change rate as the replication time window is small. What should be done to reduce the replication time?
A. Use Transfer Primary Access.
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.
You are creating a deployment plan for a new Hitachi NAS Platform customer that will meet their recovery and data consolidation requirements for their NFS and CIFS data. Which two key infrastructure areas must you identify for the design? (Choose two.)
A. Recovery Point Objective
B. types of servers
C. Recovery Time Objective
D. number of NDS servers
You are designing a solution with a Hitachi NAS Platform cluster connected to a Hitachi AMS2000 Family storage system with SAS disk drives. Which two actions will optimize performance? (Choose two.)
A. Configure at least 4 LUNs per RAID group.
B. Configure 1 LUN per RAID group.
C. Disable superflush on each system drive.
D. Set the correct superflush setting on each system drive.
A customer has asked you to plan a server migration from their existing Microsoft Windows storage server cluster to their Hitachi NAS platform. The customer requires that namespace be preserved so that the migration is transparent to their end-users. Which three actions will achieve the desired result? (Choose three.)
A. Use CNAME records to preserve UNC paths on cut-over.
B. Move the IP addresses to the EVSs from the original source server.
C. Rename the EVS CIFS server name to the original source server name on cut-over.
D. Change the UNC path in the logon scripts to point to the new server names given to the EVS CIFS server instances.
E. Use DFS and link both the EVS CIFS server instances and the original servers to the same context.
The administrator of a Hitachi NAS Platform wants to automate the replication of a directory called "Finance" within the file system called "accounts". Other data in this file system should not be replicated. Which product should be used to achieve this?
A. Hitachi TrueCopy (TC)
B. Hitachi Universal Replicator (HUR)
C. Incremental Data Replication
D. Data Migration
You are planning a data migration from a distributed Windows file server environment to a Hitachi NAS platform. You have discovered that some of the applications use hard-coded IP addresses. You have also identified that login scripts are used to map network drives for the end users. Which two methods can you use to minimize impact during the migration? (Choose two.)
A. Modify the login scripts to point to the new location regardless of host name or IP address.
B. Use CNAME records to preserve the IP addresses for hard-coded applications.
C. Use the same IP addresses on the EVSs as the original server for applications.
D. Use CNS to present a unified namespace and transparently migrate the applications.
A customer wants to use the data migration function with their Hitachi NAS Platform. Which three criteria are used by this function? (Choose three.)
A. by last access
B. by source file system block size
C. by file name
D. by path
E. by protocol type
