Hitachi Data Systems Certified Expert - Replication solutions implementation Sample Questions:
1. A customer has a TrueCopy Asynchronous environment between two USP100 arrays with a cascaded
ShadowImage off of the TrueCopy secondary volumes at the recovery site. The customer would like the
ShadowImage volumes synchronized and suspended every four hours for ata protection from a rolling
disaster. Which steps should be scripted to ensure data consistency on the ShadowImage volumes with
the lowest impact to the recovery point?
A) 1) Resynchronize ShadowImage volumes.
2 ) Suspend ShadowImage volumes using At-Time Split.
B) 1) Suspend TrueCopy volumes.
2 ) Resynchronize ShadowImage volumes.
3 ) Suspend ShadowImage volumes.
4 ) Resynchronize TrueCopy volumes.
C) 1) Resynchronize ShadowImage volumes using Quick Split.
2 ) Suspend ShadowImage volumes.
D) 1) Suspend TrueCopy volumes.
2 ) Resynchronize ShadowImage volumes.
3 ) Suspend ShadowImage volumes using At-Time Split.
4 ) Resynchronize TrueCopy volumes.
2. 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 on separate parity groups than the production volumes.
B) The pool should be defined as being 10TB in size.
C) The pool should be defined as being 7TB in size.
D) The pool should be defined on the same type of RAID groups as the production database.
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 turnaround times become unacceptable at longer distances.
B) TrueCopy Synchronous reports the ending status to the host only after the S-VOL update copy
operation is complete.
C) TrueCopy Synchronous maintains consistency of data with time stamping and sequence numbering.
D) TrueCopy Synchronous can register a maximum of sixteen remote control units (CUs) for one local
CU.
E) TrueCopy Synchronous guarantees an RPO of zero.
4. A customer is planning to use Universal Replicator for Disaster Recovery of a normal transactional
database (e.g. Oracle, DB2). Which two must be included in the same Journal Group? (Choose two.)
A) transaction logs
B) database dumps
C) application binaries
D) data files
5. A customer uses ShadowImage to create a copy of an online UNIX database so that it can be mounted
and started on another server for testing purposes. Which two should be scripted on the recovery server
prior to resynchronizing the ShadowImage pairs to ensure any volume manager changes are reflected on
the recovery server after the next ShadowImage suspend? (Choose two.)
A) unmount filesystem(s)
B) perform fsck on the filesystem(s)
C) SCSI inquiry to discover device(s)
D) deport/export disk group(s)
