A. AIX with the XIV connected to itB. SVC with the XIV connected to itC. N series gateway with XIV as back-end storageD. SONAS gateway with XIV as back-end storageAnswer: DQUESTION: 60When is the best time to complete a TDA for XIV?A. after the XIV hardware is installedB. before the customer starts to use the XIV hardwareC. after the XIV hardware is orderedD. during the pre-sales activity before the hardware is orderedAnswer: DQUESTION: 61A customer reports performance problems on an XIV Gen3 system. After furtheranalysis of performance statistics, it appears that latency is high for reads but writesare acceptable. I/O size is generally small, with more writes than reads.Whichoption is likely to help the situation?A. implementvolume striping on the hostB. installSSDsintheXIVsystemC. install ECoE adapters in the hostD. enable IBM Easy Tier on the volumesAnswer: BQUESTION: 62For optimum redundancy, how many paths between the host and a 15 module XIVshould be configured for each LUN?A. 12 pathsB. 6 pathsC. 4 paths19

D. 2 pathsAnswer: BQUESTION: 63A customer wants to ensure resource availability for their SAP application byimplementing Q0S. How could the performance class be defined?A. limited to 10,000 IOPS and add the SAP application servers to itB. limited to 10,000 IOPS and add all hosts except the SAP application to itC. for half of the interface modules add all hosts, with the remaining modulesserving the SAP applicationD. for half of the interface modules add the SAP application, with the remainingmodules serving all other I/OAnswer: BQUESTION: 64A customer complains that their SAP database now performs worse than it didbefore being migrated from traditional RAID storage to XIV. The database wasconfigured using 20 x 200GB XIV LUNs presented to an AIX 6 host OS wherethey are concatenated and striped into six volumes for the databases and logs. Nochanges have been made in the transition to XIV. What if anything can be done toimprove performance?A. the SAP volumes should be put into a QoS Performance ClassB. add Fibre Channel adapters to the host and balance volumes across the adaptersC. implement static load balancing and increase the queue depth of the hostadaptersD. the databases should be reorganized into larger volumes on the XIV and notstriped within the OSAnswer: DQUESTION: 65Which two of the following IBM products assure online data migration?(Selecttwo)20

A. DS8870B. XIV Storage SystemC. SAN Volume ControllerD. DS5000seriesE. FlashSystemsAnswer: B, CQUESTION: 66A customer wants to know how much capacity has been consumed against theCapacity on Demand entitlement on their XIV system. How would the technicalspecialist determine the capacity consumed?A. running the XCLI command cod listB. running the XCLI command system capacity listC. running the XCLI command vol list and summing the Used Capacity columnD. looking at the soft consumed capacity in the bottom left corner of the XIV GUIAnswer: AQUESTION: 67What is the maximum period of time the XIV system stores detailed host andvolume data?A. foreverB. 365daysC. 90daysD. 30daysAnswer: DQUESTION: 68Based on best practice, what is the optimal number of SVC Fibre Channelconnections to a full 15 module XIV?A. connect the SVC to 6 XIV portsB. connect the SVC to 9 XIV portsC. connect the SVCto 12 XIV ports21

D. connecttheSVCtol6XlVportsAnswer: CQUESTION: 69Following a proof of concept, it has been determined that an eleven module XIVsystem containing 2 TB drives is the minimum configuration suitable for theworkload, which consists primarily of random writes. The customer is concernedabout the upfront costs so the sales representative has suggested a six modulesystem with 3 TB drives, which would also provide amplecapacityfor theapplication. Given the customer’s concerns, which configuration should thetechnical specialist recommend to best meet the customer’s requirements?A. a six module XIV with 3 TB drives and SSDsB. an eleven module XIV with 3 TB drives and six CoD activations C. an elevenmodule XIV with 2 TB drives and eight CoD activations D. a nine module XIVwith 2 TB drives and six CoD activationsAnswer: CQUESTION: 70When creating a thin provisioned volume on an XIV the maximumcapacityislimited by:A. the vol size max configuration parameterB. the availablecapacityin the XIV systemC. the softcapacityof the storage pool where the volume residesD. the hard capacity of the storage pool where the volume residesAnswer: C22
