Skills Being MeasuredThis exam measures your ability to accomplish the technical tasks listed below.The percentages indicate the relative weight of each major topic area on the exam.The higher the percentage, the more questions you are likely to see on that content area on the exam.

The information after “This objective may include but is not limited to” is intended to further define or scope the objective by describing the types of skills and topics that may be tested for the objective. However, it is not an exhaustive list of skills and topics that could be included on the exam for a given skill area. You may be tested on other skills and topics related to the objective that are not explicitly listed here.
Plan Business Intelligence (BI) Infrastructure (15%)
  • Plan for performance.
    • This objective may include but is not limited to: optimize batch procedures: extract, transform, load (ETL) in SQL Server Integration Services (SSIS)/SQL and processing phase in Analysis Services; configure Proactive Caching within SQL Server Analysis Services (SSAS) for different scenarios; understand performance consequences of Unified Dimension Model (UDM) and Data warehouse (DWH) design; analyze and optimize performances of Multidimensional Expression (MDX) and Data Analysis Expression (DAX) queries; optimize queries for huge data sets; understand the difference between partitioning for load performance versus query performance in SSAS; appropriately index a fact table; optimize Analysis Services cubes in UDM; create aggregations using Usaged Based Optimizations

  • Plan and manage upgrades.

    • This objective may include but is not limited to: plan change management for a BI solution
  • Maintain server health.

    • This objective may include but is not limited to: design an automation strategy
Design BI Infrastructure (16%)
  • Design a security strategy.
    • This objective may include but is not limited to: configure security and impersonation between database, analysis services and frontend; implement Dynamic Dimension Security within a cube; configure security for an Extranet environment; configure Kerberos Security; skills on authentication mechanisms, ability to build secure solutions end to end; design security roles for calculated measures; understand the tradeoffs between regular SSAS security and dynamic security; plan and implement security requirements of a BI solution
  • Design a SQL partitioning strategy.
    • This objective may include but is not limited to: choose the proper partitioning strategy for the data warehouse and cube; implement a parallel load to fact tables by using partition switching; use data compression in Fact tables
  • Design a backup strategy.

    • This objective may include but is not limited to: design a High Availability (HA) and disaster recovery (DR) strategy; proactively preventing issues
  • Design a logging and auditing strategy.
    • This objective may include but is not limited to: design a new SSIS logging infrastructure (i.e. info available thru the catalog views); validate data is balancing and reconciling correctly
Design a Reporting Solution (24%)
  • Design a Reporting Services dataset.
    • This objective may include but is not limited to: data query parameters; creating appropriate SQL queries for an application (MDX queries); managing data rights and security; extracting data from Analysis Services; balancing query-based processing versus filter-based processing; managing data sets through the use of stored procedures
  • Manage Excel Services/Reporting for SharePoint.
    • This objective may include but is not limited to: configure data refresh schedules for PowerPivot published to SharePoint; publish BI info to SharePoint; use SharePoint to accomplish BI administrative tasks
  • Design a data acquisition strategy.

    • This objective may include but is not limited to: identify the data sources that needs to be used to pull in the data; determine the changes (incremental data) in the data source (time window); identify the relationship and dependencies between the data sources; determine who can access which data; what data can be retained for how long (regulatory compliance, data archiving, aging); design a data movement strategy; profile source data
  • Plan and manage reporting services configuration.
    • This objective may include but is not limited to: native mode

    • This objective may include but is not limited to: linked reports, drill-down reports, drill-through reports, migration strategies, access report services API, sub reports, Code-Behind strategies; identify when to use Reporting Services, Report Builder, or Crescent; design/implement context transfer when interlinking all types of reports (RS, RB, Crescent, Excel, PowerPivot); implement BI tools for reporting in SharePoint (Excel Services versus Performance Point versus Reporting Services); select a subscription strategy
Design BI Data Models (34%)
  • Design the data warehouse.
    • This objective may include but is not limited to: design a data model that is optimized for reporting; design & build a cube on top; design enterprise data warehouse (EDW) and OLAP cubes; choose between natural keys and surrogate keys when designing the data warehouse; use the facilities available in SQL Server to design, implement and maintain a data warehouse (partitioning, slowly changing dimensions (SCD), change data capture (CDC), Clustered Index Views etc.); identify design best practices; implement a many-to-many relationship in an OLAP cube; design a data mart/warehouse in reverse from an Analysis Services cube (or empty Analysis Services cube that was created referring requirements); use rowstamp in the data warehouse; choose between performing aggregation operations in the SSIS pipeline or the relational engine; select surround architecture
  • Design a schema.
    • This objective may include but is not limited to: multidimensional modeling starting from a star schema; relational modeling for a Data Mart; choose or create a topology
  • Design cube architecture.
    • This objective may include but is not limited to: produce efficient aggregated cubes; partition cubes and build aggregation strategies for the separate partitions; design a data model; choose the proper partitioning strategy for the data warehouse and cube; design the data file layout for a data warehouse keeping maximum performance in mind; given a requirement, identify the Aggregation method that should be selected for a measure in a MOLAP cube; design cube aggregations to maintain a balance between storage and performance; performance tune a MOLAP cube using aggregations; design a data source view; cube drill-through and write back actions
  • Design fact tables.
    • This objective may include but is not limited to: design a data warehouse that supports many to many dimensions with factless fact tables
  • Design BI Semantic Models.
    • This objective may include but is not limited to: plan for a multidimensional cube; write a UDM model with many to many (this is related to MDX/BISM code, but it is a good example for exercises; choose between UDM and BISM depending on the type of data and workload
