1 HP ExpertOne exam preparatin guide Architecting Multi-site HP Strage Slutins Exam descriptin This guide helps yu t study fr the Architecting Multi-site HP Strage Slutins (HP0-J67) exam. Yu can benefit frm this guide whether yu are attempting t expand yur existing HP certificatin r yu have experience implementing and managing anther vendr s Enterprise Strage slutins and want t get certified with HP. T pass the exam, yu will need t demnstrate an understanding f the skill requirements fr Strage Architect and Strage Cnsultant fcused individuals that have the right knwledge t supprt the sales representatives at the custmer site and prepare a cmplete and supprted slutin fr a custmer. The training will review, and use case study lab exercises t expand the skills f Strage Prfessinals t cnsult, Architect, design and prpse slutins in the HP Strage prtfli. Wh shuld take this exam? Senir strage architects wh lead a team designing strage envirnments and wh desire t leverage HP Cnverged Strage Systems in multi-site envirnments. The individual shuld have an average f 3-5 years experience designing and architecting strage slutins in a multi-vendr envirnment. This training is imprtant fr strage IT prfessinals f HP channel partners, HP pre-sales emplyees and enterprise level rganizatins wh need t credibly design and prpse tailred strage slutins t mst effectively meet enterprise level, r multi-site, business needs with ptimum ROI.

Review and validate the prpsal. Present the slutin t the custmer. Tips fr taking this exam This exam assesses whether yu have the knwledge and skills that a Strage Architect requires n the jb. Therefre, many test items present a scenari, which utlines a particular envirnment r prblem. Yu may als need t use exhibits t cmplete the test items successfully. Take the time t read the entire questin and cnsider all f the ptins carefully befre yu answer. If the questin indicates that it features an exhibit, study the exhibit and reread the questin. Make sure t select the answer that crrectly respnds t the questin that is asked, nt simply an answer that includes sme crrect infrmatin. If the questin asks fr mre than ne answer, remember t select each crrect answer. Yu will nt receive partial credit fr a partially crrect answer. Sample questins Use the fllwing questins t help assess whether yu are ready t take the exam. Answers t these sample questins are prvided at the end f this guide. 1. Yu are wrking with a lcal children's hspital n a full strage refresh prpsal. The hspital has implemented a three-tier strage strategy as detailed belw. Tier 1 - Business critical 24x7 databases, applicatins, and data warehuses. Als includes any ther applicatins that have high availability and heavy write perfrmance. This data is replicated t a disaster recvery site t ensure n data lss ccurs in additin t standard backup practices. Currently 50 TB n HP XP Tier 2 - General user file shares and nn-critical databases. Minimal dwntime can be tlerated, and high perfrmance is nt required. This data is backed up daily. Currently 150 TB n multiple HP EVAs. Tier 3 - Lng-term archives f user data. The data is mved frm Tier 2 t Tier 3 as it ages. Dwntime can be tlerated, but data must be maintained. Backups are nly dne when new data is added t the archive. There are currently 250 TB n multiple HP P2000s. Csts fr nging maintenance and management are escalating, and the hspital is lking fr ways t reduce csts and re-deply strage management staff even with the annual 10% grwth. Yu are designing an HP 3PAR StreServ slutin t meet their needs and are using the HP Strage Sizer t make yur calculatins. Which wrklad mix meets the hspital's needs fr strage fr the next year? 2
