单选题 A customer needs a remote data copy, data migration, and off-site backup solution. The solution cannot impact application performance. The sites are over continental distances.  Which  characteristic of DS8700 Global Mirror makes it a good fit for this customer()

A

it provides synchronous mirroring on both sides

B

it can be implemented withoutFlashCopy volumes at the target site

C

with Global Mirror, the Metro Mirror functions can be used over continental distances

D

it has almost no impact on application performance because of its extremely short and adjustable coordination time

单选题 A customer wants to collect performance data from a newly installed IBM System Storage DS8700 to determine if the system meets expected benchmarks using their application test data.  Which tool best gathers the performance data()

A

IBM DS Storage Manager

B

Tivoli Storage Resource Manager

C

Tivoli Storage Productivity Center for Disk

D

Tivoli Storage Productivity Center for Data

单选题 A customer has purchased three IBM System Storage DS8700 systems and would like to have their administrators trained.  Which training alternative provides the necessary training with the least financial impact()

A

purchase the training CD for the disk subsystem and have the staff do self-paced training

B

have the IBM Service Support Representative perform the training

C

contact IBM Education Services for an onsite training class

D

send one person at a time to an IBM training session

单选题 A customer has a storage requirement for a mixed IBM Power AIX and System z environment. They require approximately 3 TB of high performance disk for their System z environment. They require approximately 32 TB of low-performance disk for their System p environment. The storage specialist is using Capacity Magic to configure an IBM DS8700.  Which configuration is most appropriate for this customer()

A

2 x 300 GB 15k rpm disk drive sets for System z; and 4 x 2 TB 7.2k rpm disk drive sets for Power AIX

B

4 x 146 GB 15k rpm disk drive sets for System z; and 4 x 2 TB 7.2k rpm disk drive sets for Power AIX

C

2 x 300 GB 10k rpm disk drive sets for System z; and 4 x 300 GB 15k rpm disk drive sets for Power AIX

D

2 x 300 GB 15k rpm disk drive sets for System z; and 2 x 1 TB 7.2k rpm disk drive sets for Power AIX

单选题 What is a benefit of storage virtualization technology in the IBM System Storage DS8800()

A

fewer expansion units are needed

B

multiple workloads can be managed separately

C

resource isolation is eliminated

D

Linux can run in LPAR mode

单选题 A global customer’s IT strategy is based upon two DS8000 systems and an N series gateway. They want to protect their  business by implementing a disaster recovery solution. The storage specialist has recommended cascaded mirroring.  Which of the following is the business benefit of cascaded replication()

A

it is cost efficient, as a single N series or DS8000 can have its controllers split between the  primary and secondary site and use semi- synchronousmirroring while using asynchronous mirroring to a third site

B

the second site acts as a repeater station so that greater geographical distances can be achieved

C

ITprovides high availability together with disaster recovery by implementing Metro/Global Mirror across three geographically dispersed systems

D

it guarantees data protection by implementing two synchronous copies of the primary site data

单选题 A customer has an existing IBM System Storage DS8700 2-way model with 8 mega packs of 300 GB disks and 16 fibre ports.  How many additional fibre ports and mega packs can be installed in the base frame()

A

16fibre ports and 0 mega packs

B

4fibre ports and 8 mega packs

C

8fibre ports and 4 mega packs

D

12fibre ports and 0 mega packs

单选题 A storage specialist needs to automate some tasks triggered in the event of disaster recovery.  What is the best solution to accomplish this()

A

using the DS GUI, step through Real Time Manager, Copy Services, Create custom scripts; actions and event conditions can be defined that triggerthe script; there is no need for a password

B

create a shell script usingdscli commands; trigger the script from the operating system, and call the script using the -pwd option with the password

C

create a password file; create a shell script using dscli commands; trigger the script from the operating system

D

create a password file; create a shell script usingdscli commands; trigger the script from the operating system; call the dscli script with the dscli -script  -pwdfile command
