Example Questions

ShadowImage can be used to copy LUNs when they are assigned to which host interface type(s)? A customer who has purchased an AMS2500 storage system is looking for a multipathing software solution for heterogeneous platforms. Which three features does Hitachi Dynamic Link Manager provide the customer with? (Choose three.) A customer uses Copy-on-Write Snapshot to create a point-in-time copy (V-Vol) of their data for backup. When is the customer able to mount the V-Vol? Which two features of Hitachi Copy-on-Write Snapshot enable the rapid creation of a data copy? (Choose two.) A customer is reviewing mid-tier arrays to support a dual infrastructure environment; MS Exchange and backup to disk. Write I/O from the backup to disk fills up cache because it is writing to slower SATA drives. Which AMS500 feature isolates the MS Exchange application from the effects of backup to disk I/O? What are two reasons why a customer would want to use Host Groups on an AMS2100? (Choose two.) A customer has a WMS100 array to support an archiving solution. Archiving solutions are batch processes that have low performance requirements. Which configuration alternative is supported on the WMS100? A customer is using Copy-on-Write Snapshot to store multiple copies of a P-Vol. After the last snapshot, the data on the P-Vol is extensively modified. What happens if the Data Pool becomes full? A customer wants to provide OLTP database and large file NAS services on a single AMS2300 system. How can the AMS2300 features be used to help the customer achieve this objective? A customer has an AMS2100 connected to a host which has two paths to CTL0 and two paths to CTL1. The customer has installed Hitachi Dynamic Link manager and load balancing is enabled. With all systems working correctly , over how many paths will I/O to an LU be Load-balanced? Which statement defines the "damping" function with respect to triggering alerts in HiCommand Tuning Manager for performance monitoring and notification? A customer uses Copy-on-Write Snapshot to create a point-in-time copy (V-VOL) of their data for backup. When can the snapshot be used to backup the production data? Which two features of the AMS2000 controllers eliminate the need for additional load balancing software required for VMware environments? (Choose two.) What are two performance reasons why you would recommend choosing an AMS2500 over an AMS2300 system? (Choose two.) Which two statements are true about the AMS1000? (Choose two.) A storage administrator wants to use True Copy to replicate volumes between an AMS2100 and an AMS2300. Hom many S-Vol copies can be made from a single P-Vol? What are two reasons why a customer would want to use Host Groups on an AMS2100? (Choose two) A customer wants to create a no-single-point-of-failure SAN using the HDS AMS200 as inexpensively as possible. Which AMS200 configuration satisfies their needs? Which two features of Hitachi Copy-on-Write Snapshot enable the rapid creation of a data copy? (Choose two) A customer requires a new modular storage array which will use parity for data protection. When a drive fails in a RAID 5 group, the remaining disks are each a single point of failure. A requirement is that the vendor must minimize the amount of time the array is in a single point of failure state following a disk failure. Which two features of the AMS500 support the requirement? (Choose two.) A customer wishes to minimize disruptions due to planned or unplanned outages. Which two features of Hitachi Copy-on-Write Snapshot facilitate these requirements? (Choose two) When using TrueCopy asychronously, what is the primary function of consistency groups? Which two benefits are provided by HDD Roaming in the Adaptable Modular Storage family? (Choose two.) Which two actions can be performed with Copy-on-Write Snapshot on AMS2000 systems? (Choose two) What are two values that HiCommand Device Manager software provides about storage management? (Choose two.) What is an advantage of TrueCopy Synchronous operation? What are two conditions for migrating data using Hitachi Tiered Storage Manager? (Choose two) During a customer install of an AMS subsystem the controller ports do not log into the SAN fabric. The port indication light on the SAN switch indicates a port login failure. Using the Storage Navigator Modular GUI you need to configure the AMS Fibre Channel controller to work with their SAN fabric. Which topology would you select in Storage Navigator that would allow you to connect to their SAN switch? Which two statements accurately describe Modular Volume Migration? (Choose two.) A customer has a storage array that supports a large MS Exchange environment. The array is bottlenecked at the array host ports. The customer has a requirement for a new modular array that will solve this problem. Which AMS500 feature will support the requirements of this requirement? A customer is evaluating AMS storage arrays to provide storage for a high performance database that must be available 24x7. Which HDS supported configuration meets their needs? What is the primary function of TrueCopy Extended Distance software in business continuity? After a performance analysis a customer decides to move LUNs from RAID Group 0 to RAID Group 10. Which two statements regarding Modular Volume Migration are true? (Choose two.) A customer requires a new modular storage array which will use parity for data protection. A requirement is that the vendor must minimize the amount of time the array is in single point-of-failure state following a disk failure. Which two features of the AMS2300 support the requirement? (Choose two) Which three methods are available for creating a RAID Group using Storage Navigator Modular 2? (Choose three.) For the WMS/AMS product families, if the replacement HDD is of a larger capacity and of a different RPM than the failing HDD, how does the system respond? What is required when implementing a TrueCopy Extended Distance replication solution? IT centers that have Microsoft Windows production systems that must operate in a highly available 24 x 7 environment require business continuity support. Which HDS solution provides support for this need with MS Windows plug-and-play? HDS Adaptable Modular Storage models (AMS200 and AMS500) provide efficient cost-effective storage for medium and small businesses. Which three attributes characterize the AMS product line? (Choose three.) Which two additional license based features can be enabled on an AMS storage subsystem using the Storage Navigator Modular GUI? (Choose two.) TrueCopy software can be used in combination with some other replication products. Which three configurations are valid? (Choose three.) An AMS2300 customer is concerned about protecting their mission critical data from unauthorized access. What would they gain from enabling Host Group Security? A customer is using Storage Navigator Modular to setup RAID Groups on a new AMS2100. Which three RAID levels are supported? (Choose three.) Which two methods are available for creating a RAID Group using Storage Navigator Modular 2? (Choose two.) A customer wishes to purchase a global solution that will respond to their data protection, archival and restore needs. They seek an alternative solution to an Hitachi Content Archival Platform (HCAP) proposal. Which solution would you choose? Which two transport methods are used by HiTrack Monitor to report errors? (Choose two) You set a warning threshold to take pre-emptive action when a critical resource approaches an unacceptable capacity level. What are two examples of critical resources that could affect application performance? (Choose two.) A customer requires a new modular storage array which will use parity for data protection. A requirement is that the vendor must minimize the amount of time the array is in a single point-of- failure state following a disk failure. Which two features of the AMS2300 support the requirement? (Choose two.) What are two advantages of TrueCopy Extended Distance replication? (Choose two.) A modular storage array is connected to a TagmaStore USP system. Internal volumes that contain data that are not critical to the business will be migrated from the USP to the modular array in order to save money. The application using the data should not have any disruption during or after the volume migration. What happens to the source volume's LDEV number after the volume has been migrated?
