Hitachi Data Systems Certified Expert - Replication solutions implementation Sample Questions:

1. A customer is concerned about a large number of changes being made daily to production systems over a
period of three weeks. The customer decides to make Copy-on-Write SnapShot copies of the database at
the start of every day to easily restore the most recent version should it be necessary. Each copy must be
kept for one week. The average change to the database is 10 percent daily. The database is 10TB in size.
Which two considerations are relevant? (Choose two.)

A) The pool should be defined as being 10TB in size.
B) The pool should be defined on the same type of RAID groups as the production database.
C) The pool should be defined as being 7TB in size.
D) The pool should be on separate parity groups than the production volumes.

2. A customer is replicating data between sites using Universal Replicator. They are using CCI at each site
running on Solaris servers with korn shell; both CCI servers are also used to control ShadowImage pairs
on each array. The CCI device group is named UR_db01 and each server is using the horcm2 daemon for
the Universal Replicator pairs. Which two sets of commands will set the correct parameters and display
the status of the Universal Replicator pairs in the CCI device group? (Choose two.)

A) pairdisplay -g UR_db01 -IM2
B) unset HORCMINST; export HORCC_MRCF=2; pairdisplay -g UR_db01
C) export HORCMINST=2; unset HORCC_MRCF; pairdisplay -g UR_db01
D) pairdisplay -g UR_db01 -IH2

3. Your customer must decide if TrueCopy Asynchronous or TrueCopy Synchronous is the best solution.
Which three statements describe TrueCopy Synchronous characteristics? (Choose three.)

A) TrueCopy Synchronous maintains consistency of data with time stamping and sequence numbering.
B) TrueCopy Synchronous turnaround times become unacceptable at longer distances.
C) TrueCopy Synchronous guarantees an RPO of zero.
D) TrueCopy Synchronous reports the ending status to the host only after the S-VOL update copy
operation is complete.
E) TrueCopy Synchronous can register a maximum of sixteen remote control units (CUs) for one local
CU.

4. A customer asks you to review a plan for installing HiCommand Protection Manager (HPtM) software to
protect Microsoft Exchange 2003. You are aware that Exchange 2003 is a very critical business
application for this customer. Their plan is to use one large LUN for the public store and check point files
and second large LUN for the mail box store and the transaction log. Which solution will provide the
customer with maximum protection?

A) The customer should use four different mounted LUNs: two LUSE LUNs for public and mailbox stores,
one for checkpoint files, and one for transaction log files
B) The customer should use four different mounted LUNs: one for public stores, one for mailbox stores,
one for checkpoint files, and one transaction log files.
C) The customer should use three different mounted LUNs: one for public stores and mailbox stores, one
for checkpoint files, and one for transaction log files.
D) The customer should use three different mounted LUNs: one for public stores, one for mailbox stores
and checkpoint files, and one for transaction log files.

5. You are setting up an Hitachi Storage Cluster (HSC) for Microsoft Environments for a customer who
wishes to have a fileshare resource called engDep highly available. This fileshare will be configured on a
Physical Disk called diskE . The Generic Script resource is called SCScript. What is the correct
dependency order for setting up these resources?

A) EngDep is dependent on diskE and engDep is dependent on SCScript
B) EngDep is dependent on diskE and diskE is dependent on SCScript
C) DiskE is dependent on engDep and diskE is dependent on SCScript
D) EngDep is dependent on SCScript and diskE is dependent on SCScript
