Exam Language(s): English

1.What is oversubscription in the context of virtual libraries?A.more capacity allocated than physically installedB.more libraries created than currently licensedC.more virtual drives created than currently licensedD.more data streams than the library can processAnswer: A  2.With the maximum number of supported nodes, running the VLS software version 3.x, how many arrays are supported in a VLS9000?A.8B.16C.32D.64Answer: B  3.What is an advantage of using the automigration feature of virtual library systems?A.The tapes are analyzed during backup to migrate all files. After the content is decoded, only those files are compared to the same files from the previous backup.B.It leverages object-level differencing code with a design centered on performance and scalability.C.The destination tapes are block-by-block copies of the source tapes and can easily be restored by any tape library to which the backup application has access.D.It delivers fastest restores from recently backed up data, maintains the complete most recent copy of backup data, but eliminates duplicate data in previous backups.Answer: C  4.What are advantages of having separate zones for disk storage systems and disk-to-disk backup systems in storage area networks? (Select two.)A.The physical and virtual tape controllers do not discover disk controllers.B.Administrative and management costs are lower.C.Tape multipathing functionality can be used to map the physical and virtual devices.D.There is less host access and improved target and LUN shifting.E.Performance is improved, due to dedicated HBAs for disk and tape access.Answer: AE  5.When would you opt to use an HP Data Protector environment with Advanced Backup to Disk licensing in conjunction with a virtual library system instead of a traditional backup-to-disk solution? (Select two.)A.when you want to use target-based compressionB.when the environment consists mainly of LAN clientsC.when you want to use existing SAN storage or locally attached storageD.when there are many SAN hosts writing to diskE.when there are relatively few SAN hosts writing to disk Answer: AD  6.What is a benefit of using HP Data Protector Software’s capacity-based licensing model with an HP Virtual Library System?A.Deduplication is included in the capacity license.B.Four times the license capacity is available for short-term use.C.It simplifies management of the virtual library devices.D.No penalty is imposed when configuring additional virtual drives or libraries.Answer: D  7.Which statement is true about automigration using the Smart Copy functionality?A.The backup application can immediately use the destination library if the source library fails.B.Smart Copy acts as a transparent disk cache to the physical library.C.A backup application can only use Smart Copy if it supports the SMI-S interface.D.Because the copy jobs are initiated from the virtual library, the backup application will not be aware of any copy failures.Answer: C  8.What do the HP StorageWorks Virtual Library System 6200/6600 appliances provide? (Select two.)A.resiliency against a single MSA20 volume failureB.support of up to two MSA20 disk enclosures at any timeC.online addition of physical storage capacityD.fewer media failures due to the use of virtual mediaE.performance enhancements for single file restores due to lower tape load and positioning/seek timesAnswer: DE  9.What is a key functionality offered with HP StorageWorks Virtual Library System storage virtualization?A.fully automated capacity addition and removalB.reassignment of resources as requirements changeC.ability to enable and disable tape compression on an as-needed basisD.automated LUN to host assignmentAnswer: B  10.How is storage space assigned between the virtual cartridges and the physical disks in the HP StorageWorks Virtual Library System storage pool?A.Storage space is dynamically assigned as it is used.B.Each virtual library has a fixed amount of storage space available for cartridges to use.C.Each virtual tape drive has a fixed amount of storage space available for cartridges to use.D.When the media is created, full storage space is reserved within the storage pool.Answer: A
