2 QUESTION: 104 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 Answer: B, D QUESTION: 105 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. Answer: A QUESTION: 106 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. 36

3 D. Create an additional IP address on the source EVS. Answer: B QUESTION: 107 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 Answer: A, C QUESTION: 108 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. Answer: B, D QUESTION: 109 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 cutover. 37

4 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. Answer: A, C, D QUESTION: 110 A customer is using the JetMirror object-based replication to mirror their data to a DR site. They now want to perform a controlled failover due to a planned power outage in their primary site without losing any data. Which two statements are correct? (Choose two.) A. The customer must perform a syslock on the primary FS before failover. B. The customer must have a scheduled replication window of one hour or less. C. The customer must promote the FS on the DR site. D. The customer must do a initial synchronization before failover. Answer: A, C QUESTION: 111 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. D. A thin file system can be created with a larger maximum size than the storage pool size. Answer: B, D QUESTION: 112 A customer has 28 independent file servers with various amounts of data on each server and they would like to consolidate with a Hitachi NAS Platform. Which three factors must be considered prior to the consolidation? (Choose three.) 38

5 A. number of concurrent users B. type of applications and specific purpose of each application server C. server BIOS version D. number of mount points and shares E. number of concurrent HTTP instances Answer: A, B, D QUESTION: 113 A customer is considering deploying a Hitachi NAS Platform in their environment. They require a single mount point to allow for ease of administration and data organization. Which licensed Hitachi NAS Platform software feature would help this customer? A. storage pools B. snapshots C. File System Rollback (FSR) D. Cluster Namespace (CNS) Answer: D QUESTION: 114 You need to plan a 2-node Hitachi NAS Platform cluster microcode upgrade from 7.x to 8.x. How will the customer operations be impacted? A. All the EVSs will failover between the nodes during the upgrade. B. All the EVSs will be offline during the upgrade. C. Only NFS clients will be denied access during the upgrade. D. Only CIFS clients will be denied access during the upgrade. Answer: B QUESTION: 115 A customer is considering the purchase of a Hitachi NAS Platform model 3080 or Their infrastructure includes both 10 GbE and 1 GbE data networks and they are asking about connectivity support. Which statement is correct? A. Model 3080 only supports 1 GbE. B. Model 3080 supports 10 GbE and 1 GbE networks concurrently. 39

6 C. Model 3080 supports either 10 GbE or 1 GbE networks. D. Model 3090 only supports 10 GbE networks. Answer: B QUESTION: 116 You have architected a Hitachi NAS Platform MetroCluster solution. What is the expected behavior when the primary storage fails? A. Automatic EVS failover cannot occur. B. All replication policies get deleted. C. All snapshots are deleted. D. The backup SMU is promoted to primary. Answer: A QUESTION: 117 A customer would like to attach a Hitachi NAS Platform 3100 to an existing Hitachi AMS2300 storage system. They have specific performance requirements and they would like to know if the AMS2300 will meet these requirements. Which information should you analyze from the "perfmon" output of the AMS2300 prior to recommending a solution? (Choose three.) A. disk drives operating rate B. microcode version C. license keys D. controller write pending rate E. disk IO rate (IOPS) Answer: A, D, E QUESTION: 118 A customer has purchased a 2-node Hitachi NAS platform 3080 cluster.
