至于“DatamodelsarecomponentsofaMetadatarepository.”,數(shù)據(jù)模型的確是元數(shù)據(jù)存儲庫的內(nèi)容之一,大家也不要去追究這個選項講得不完整,DAMA的題都一樣,但至少比其它幾個選項要好,至少沒錯。40.TheMetadatarepositoryenablesustoestablishmultipleperspectivesofdata.Theseare:A、InternalandexternalB、TheBusinessandTechnicalPerspectiveC、Dimensionalandnon-dimensionalperspectiveD、3rdnormalformandun-normalisedE、Structuredandunstructured答案:B解析:三種主要元數(shù)據(jù)類型,業(yè)務(wù)元數(shù)據(jù),技術(shù)元數(shù)據(jù),操作元數(shù)據(jù)。41.Tocontinuallyimprovethequalityofdataandinformationanorganizationmustconsiderwhichoneofthefollowing?A、Theclarityandsharedacceptanceofdatadefinitions.B、MaximizetheeffectiveuseandvalueofdataandinformationassetsC、Controlthecostofdatamanagement.D、UnderstandtheinformationneedsoftheenterpriseanditsstakeholdersE、All答案:A42._________governanceconsistsofaddressingacurrentcriticalissueA、PerformanceB、CentralC、Pre-emptiveD、ProtectiveE、Reactive答案:E43.Asearchenginedatabaseispopulatedbyawebcrawlerorspidersoftwarethatusuallyprocessesas:A、Linearlyindependent,nearexact(LINE)B、Fundamentallyavailable,consistentlytrue(FACT)C、Atomic,consistent,isolated,durable(ACID)D、Basicallyavailable,softstate,eventually,consistent(BASE)E、Continuallyrepeating,alwaysperforming(CRAP)答案:D解析:ACID和BASE是兩個對立體,BASE強(qiáng)調(diào)擴(kuò)展,更適合互聯(lián)網(wǎng)見P27344.Agoalof'DocumentandContentManagement'istoensureeffectiveandefficientretrievalanduseof:A、data,butnotinformationinunstructuredformats.B、information,butnotdatainunstructuredformats.C、Dataandinformationinstructuredformats.D、Dataandinformationinunstructuredformats.E、Dataandinformationinrelationalformats.答案:D解析:文件是非結(jié)構(gòu)化數(shù)據(jù)45.InDimensionaldatamodels,whichoftheseisNOTtrueregardingMeasuresA、MeasuresarefoundinFacttablesB、CaremustbetakenifameasureisasnapshotfigureC、MeasurescanalwaysbeaddedacrossalldimensionsD、MeasuresshouldbenumericandadditiveE、Justbecauseavalueisnumericaldoesnotmeanitisameasure答案:C解析:該題考的是維度建模,稍后我做個完整的視頻解釋,這里稍作簡述。Measurescanalwaysbeaddedacrossalldimensions:中的維度表,某種意義上來說,跟參考數(shù)據(jù)是同義的,如地區(qū)維表,這里表是不能累加的,也不含指標(biāo)相關(guān)的內(nèi)容的,也不能單獨(dú)使用,必須和事實(shí)表關(guān)聯(lián)才能使用的。MeasuresarefoundinFacttables:事實(shí)表就是記錄過程數(shù)據(jù)的,如訂單數(shù)據(jù),所以是可以找到指標(biāo)相關(guān)的信息的Caremustbetakenifameasureisasnapshotfigure:這種中性描述,沒錯,雖然沒把原因?qū)懗鰜硎O聝蓚€答案:指標(biāo)是累加的數(shù)值(請參閱《華為數(shù)據(jù)之道》)46.Inadatawarehouse,wheretheclassificationlistsfororganizationtypeareinconsistentindifferentsourcesystemsthereisanindicationthatthereisalackoffocusonA、ReferencedataB、MetadataManagementC、DataModellingD、DataStorageE、Masterdata答案:A解析:組織架構(gòu)屬參考數(shù)據(jù)在DAMA中,若見到分類這種詞語,一般就指參考數(shù)據(jù)47.DatagovernancediffersfromitgovernanceinthatA、Seriousproblemscanoccurintheprojectcycle,andafteroperationalizedversusupfrontfeaturesanalysisanddesignintechnologyprojectsB、YoubuyanddeploysolutionsatincreasinglevelsofspecificationthroughtheprojectC、Seriousproblemscanbediscoveredatanyleveloftheorganizationversustop-downidentificationofrisksandissuesintechnologyD、NosinglegrouphascontrolofdataasitflowsthroughouttheorganizationversussingleownerassignmentoftechnologyE、None答案:D解析:該題用排除法,除了所選答案外,其余均是IT治理內(nèi)容,與數(shù)據(jù)治理無關(guān),題目是讓我們選擇數(shù)據(jù)治理的解釋48.AdataownerhasresponsibilityandauthorityforA、AllB、Quality,access,distributionandbusinessdefinitions.C、BusinessdefinitionsanddatasecuritymanagementD、Regulationspolicies,knowledgeofdataprivacylaws,businessrulesandbusinessobjectivesE、Distributionsandretentionofdata答案:B49.Thedeliverablesforadatamodellingprocessdoesnothavetoinclude:A、LineagedescribingwherethedatacamefromB、IssuesandoutstandingquestionsC、OneormorediagramsD、ThestepsinthebusinessprocessthatusethedataE、Definitionsforentities,attributesandrelationships答案:D解析:Thestepsinthebusinessprocessthatusethedata:應(yīng)該是業(yè)務(wù)架構(gòu)要交付的內(nèi)容50.Forbusinessintelligence,businessdatastewardshelpwithallofthefollowingEXCEPTA、DataqualityMetricsB、BIrequirementsC、BIissueD、ManagementmetricsE、Dimensionalmodeldevelopment答案:E51.Whatarerelationshiplabels?A、Arelationshipwithoutcardinality.B、Theverbphrasesdescribingthebusinessrulesineachdirectionbetweentwoentities.C、Aforeignkeythathasbeenrole-named.D、Thenullabilitysettingonaforeignkey.E、Anon-identifyingrelationship.答案:B解析:請P202,relationship,指兩個實(shí)體之間的關(guān)聯(lián)關(guān)系。52.Adatalineagetoolenablesauserto:A、Enablesrapiddevelopmentofdashboardreporting.B、Lineupthedatatosupportsophisticatedglossarymanagement.C、Visualisehowthedatagetstothedatalake.D、Trackthedatafromsourcesystemtoatargetdatabase;understandingitstransformations.E、Trackthehistoricalchangestoadatavalue.答案:D解析:請見P245,書上的定義:53.De-identifyingsensitivedatainadatawarehouseenables:A、CertaintyofcompletedatasetsforinterrogationB、AbypassintheneedtoassessdataqualityC、AreducedcomplexityinthedatamodelsD、IncreasedutilizationwithoutcompromisingdataprivacyE、Afocusonre-identifyingrecordswith3rdpartydatasets答案:D解析:見P330~P331,從書上可知,增加數(shù)據(jù)安全的能力,將降低效率;該題難點(diǎn)在于“在不泄露數(shù)據(jù)隱私的情況下提高利用率”,如何達(dá)成。因除了敏感數(shù)據(jù)單獨(dú)管理外,還可以用物理隔離,賬號體系等諸多手段保障安全。54.Adatawarehousedepl

維表有兩個特征:(1)字段(列)數(shù)量大:如會員,可能會有二、三十個字段(2)維表記錄數(shù)與事實(shí)表比不大,如阿里巴巴的會員記錄可能十億行(維表),但事實(shí)表(交易記錄)估計已經(jīng)超過萬億行。我拿阿里來舉例,是因?yàn)榘⒗锘敬砹司S度建模的金字塔頂端。實(shí)際上更多的情況是一千幾百個產(chǎn)品,數(shù)百萬行交易記錄。
切記,這里提的多與少,是維表與事實(shí)表作比較,千萬不要與主數(shù)據(jù)及參考數(shù)據(jù)一同分析,這是兩個概念。67.Discoveringanddocumentingmetadataaboutphysicaldataassetsprovides:A、EffectiveprojectscopemanagementB、AnestimationofbalancesheetvalueofenterprisedataC、InformationonhowdataistransformedasitmovesbetweensystemsD、InsightsintothetemporaldataqualityE、Scopingboundariesofthedatadictionary答案:C解析:見P636,該題考的是數(shù)據(jù)血緣,68.Inadatawarehouse,wheretheclassificationlistsfororganizationtypeareinconsistentindifferentsourcesystemsthereisanindicationthatthereisalackoffocusonA、DataStorageB、MasterdataC、MetadataManagementD、DataModellingE、Referencedata答案:E解析:組織架構(gòu)屬參考數(shù)據(jù)在DAMA中,若見到分類這種詞語,一般就指參考數(shù)據(jù)69.Referencedataisusedto:A、EnforceenterprisesecuritystandardsB、PopulatefacttablesinadatamartC、CategorizeorclassifydataD、DescribebackupstrategiesE、Removeduplicatecustomerrecords答案:C解析:參考數(shù)據(jù),如地區(qū)等,某種意義上來說,是把事實(shí)數(shù)據(jù)按地區(qū)進(jìn)行切片(或者說歸類)70.Bysetting,enforcingandauditingmetadatastandards,organizationshopeto:A、StandardizebusinessrulesinoperationalprocessesB、EaseofunderstandingdatadictionariesC、Ensuretheappropriateclassificationormeta-metadataD、SimplifyintegrationandenableuseE、Provideactivitiesforthedatagovernanceoffice答案:D解析:見P60871.WhichofthefollowingBESTdescribestheroleofadataintermediary?A、SomeonewhodecideswhatdataisimportanttothebusinessB、AllC、SomeonewhoisresponsiblefortranslatingbusinessrequirementsintoadatabasedesignD、Someonewhoisresponsibleformanagingthemeta-datarepositoryE、Someonewhoreceivesdatainoneformandtranscribesitintoanotherfor答案:E72.WhichofthefollowingisNOTaprimaryMasterDataManagementareaoffocus?A、IdentifyingduplicaterecordsB、ProducingreadonlyversionsofkeydataitemsC、Generatingagoldenrecord/bestversionofthetruthD、ProducingcleardatadefinitionsforMasterDataE、Providingaccesstogoldendatarecords答案:B解析:B類型題目,相關(guān)的書上的介紹請見P518,我截圖如下:并未見到提及“Producingreadonlyversionsofkeydataitems”73.AcharacteristicofinformationqualitythatmeasuresthedegreeofthedatagranularityisknownA、AggregationB、DatasetC、ScaleD、Precision答案:D74.Anapplicationusesasingleserviceaccountforalldatabaseaccess.Oneoftherisksofthisapproachis:A、ItconstrainstheapplicationfromrunningparallelprocessesB、ThedatabaserunsoutofthreadsC、TheapplicationfreezesmoreoftenD、TheabilitytotracewhomadechangestothedataE、Thedatabecomesoutoforder答案:C解析:serviceaccount指的是非操作人員帳戶,如SQLSERVER中的SYSTEM帳戶等,他們是沒有密碼的;如果所有數(shù)據(jù)庫都用一個serviceaccount,如dev,prd,uat,那假設(shè)其中某個地方引致這個account出現(xiàn)問題(如拒絕訪問WINDOW的某個目錄,而這個目錄剛好是保存數(shù)據(jù)的父目錄),將會出現(xiàn)所有環(huán)境不能訪問;又或者在修改后臺服務(wù)帳戶權(quán)限后,導(dǎo)至前臺桌面應(yīng)用不能訪問(Tableau會有此問題)
