Hitachi Hitachi Certifications HCE-5710 Questions & Answers

• Question 11:

  A customer uses Universal Replicator for Disaster Recovery for several mission critical applications. A disaster occurs at the production site and network communication is lost between the sites. Which two actions should be used to split the Universal Replicator pairs from the recovery site so the secondary volumes can be used for application recovery? (Choose two.)

  A. Issue a horctakeover -S command from the recovery site CCI server.

  B. Issue a horctakeover -S command from the recovery site Storage Navigator.

  C. Suspend the Universal Replicator pairs with S-VOL write enabled from the recovery site CCI Server.

  D. Delete the Universal Replicator pairs from the secondary site using the recovery site Storage Navigator.

  Correct Answer: AD

• Question 12:

  During a Copy-on-Write SnapShot (CoW) implementation, a customer asks you to demonstrate the Quick Restore functionality of the software. CCI for this environment is installed on a UNIX host using korn shell and the CoW CCI device group is COW_db01. Which statement is correct?

  A. This is not possible using Copy-on-Write SnapShot.

  B. Use the pairresync -g COW_db01 -fq normal -restore commands.

  C. Use the export HORCC_REST=NORMAL; pairresync -g COW_db01 -restore commands.

  D. Use the export HORCC_REST=COW_QUICK; pairresync -g COW_db01 -restore commands.

  Correct Answer: A

• Question 13:

  An AMS customer wants to copy a database over 100km to a secondary site using TrueCopy Extended Distance. The number of updates is minimal and the application's workload is very stable. Which two factors should be carefully considered? (Choose two.)

  A. How many LUNs are replicated.

  B. Which LUN types must be copied.

  C. How large should the pool be on the controllers.

  D. How large is the recovery point objective (RPO).

  Correct Answer: CD

• Question 14:

  A customer must implement a Disaster Recovery environment for a mission critical UNIX database. The production and recovery sites are 30km apart and a DWDM infrastructure is in place between the locations. The requirement is for zero data loss in the event of a disaster. Which HDS replication technology meets the customer's requirements?

  A. Universal Replicator

  B. TrueCopy Synchronous

  C. TrueCopy Asynchronous

  D. TrueCopy cascaded from a local ShadowImage

  Correct Answer: B

• Question 15:

  On the Storage Navigator frame for a TrueCopy pair operation, the "Status" column on the primary array indicates PSUS. What are three CCI commands that put the TrueCopy pairs in this status? (Choose three.)

  A. pairsplit -r from primary

  B. pairsplit -e from primary

  C. pairsplit -r from secondary

  D. pairsplit -S from secondary

  E. pairsplit -e from secondary

  Correct Answer: ACD

• Question 16:

  When integrating NetBackup with HiCommand Protection Manager (HPtM), which option should you specify on the setup GUI Command Control Interface (CCI) Linkage tab?

  A. instance number

  B. CCI installation path

  C. track size for data copy

  D. dynamic reconfiguration of secondary volume

  Correct Answer: B

• Question 17:

  The Hitachi HiCommand Protection Manager (HPtM) software uses Volume Shadow Copy Service (VSS) to protect mission critical databases, file systems and application data, Which three components does VSS coordinate to achieve this? (Choose three.)

  A. The application that requests VSS services.

  B. The programs that manage shadow copies.

  C. Copy-on-Write SnapShot designed for VSS.

  D. Hitachi Software that allows you to present storage.

  E. Applications that store persistent information on disk.

  Correct Answer: ABE

• Question 18:

  A customer is implementing Copy-on-Write SnapShot (CoW) for the first time on a Universal Storage Platform USP100 array. What should the customer do prior to creating the pool?

  A. Create the V-VOL group.

  B. Register the pool ID number.

  C. Initialize the V-VOL management area;

  D. Place the pool disks in a separate CLPR.

  Correct Answer: C

• Question 19:

  While testing a TrueCopy Asynchronous implementation, the pairs in a Copy Group suspend unexpectedly. It is determined that the suspend is due to a sidefile puncture. Which three criteria must be considered when determining the cause of the sidefile puncture? (Choose three.)

  A. insufficient journal space

  B. insufficient cache memory

  C. remote link distance too long

  D. insufficient remote link bandwidth

  E. excessive contention on secondary Array Groups

  Correct Answer: BDE

• Question 20:

  A customer has replicated his database internally using ShadowImage. Which two benefits can be expected from this approach? (Choose two.)

  A. Fewer storage units are needed for Disaster Recovery.

  B. Multiple updates can be made against the data at the same time.

  C. More reporting applications can be run against the secondary copy.

  D. The applications can be restarted faster in the event of a database corruption.

  Correct Answer: CD
