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.

  • Implement sub-queries.
    • This objective may include but is not limited to: identify problematic elements in query plans; pivot and unpivot; apply operator; cte statement; with statement
  • Implement data types.
    • This objective may include but is not limited to: use appropriate data; understand the uses and limitations of each data type; impact of GUID (newid, newsequentialid) on database performance, when to use which data type for columns
Modify Data
  • Create and alter stored procedures (simple statements).
    • This objective may include but is not limited to: write a stored procedure to meet a given set of requirements; branching logic; create stored procedures and other programmatic objects; techniques for developing stored procedures; different types of stored procedure results; create a stored procedure for data access layer; program stored procedures, triggers, and functions with T-SQL
  • Modify data by using INSERT, UPDATE, and DELETE statements.
    • This objective may include but is not limited to: given a set of code with defaults, constraints, and triggers, determine the output of a set of DDL; know which SQL statements are best to solve common requirements; use output statement
  • Work with functions.
    • This objective may include but is not limited to: understand deterministic and non-deterministic functions; scalar and table values; apply built-in scalar functions; create and alter user-defined functions (UDFs)
Troubleshoot and Optimize Queries
  • Optimize queries.
    • This objective may include but is not limited to: understand statistics; read query plans; plan guides; DMVs; hints; statistics IO; dynamic vs. parameterized queries; describe the different join types (HASH, MERGE, LOOP) and describe the scenarios in which they would be used
  • Manage transactions.
    • This objective may include but is not limited to: mark a transaction; understand begin tran, commit, and rollback; implicit vs. explicit transactions; isolation levels; scope and type of locks; trancount
  • Evaluate the use of row-based operations vs. set-based operations.
    • This objective may include but is not limited to: when to use cursors; impact of scalar UDFs; combine multiple DML operations
  • Implement error handling.
    • This objective may include but is not limited to: implement try/catch/throw; use set based rather than row based logic; transaction management
Install and Configure SQL Server
  • Plan installation.
    • This objective may include but is not limited to: evaluate installation requirements; design the installation of SQL Server and its components (including drives and service accounts); plan scale up vs. scale out basics; plan for capacity, including if/when to shrink, grow, autogrow, and monitor growth; manage the technologies that influence SQL architecture (including service broker, full text, and scale out); design the storage for new databases (drives, filegroups, partitioning); design database infrastructure; configure a SQL Server standby database for reporting purposes; Windows-level security and service level security; Core mode installation; benchmark a server before using it in a production environment (SQLIO, Tests on SQL Instance); choose the right hardware
  • Install SQL Server and related services.
    • This objective may include but is not limited to: test connectivity; enable and disable features; install SQL Server database engine and SSIS (not SSRS and SSAS); configure an operating system disk
  • Implement a migration strategy.

  • Configure additional SQL Server components.
    • This objective may include but is not limited to: set up and configure Analysis Services (AS), Reporting Services (RS), and SharePoint integration in a complex and highly secure environment; configure full-text indexing; SQL Server Integration Services (SSIS) security; filestream; filetable
  • Manage SQL Server Agent.
    • This objective may include but is not limited to: create, maintain, and monitor jobs; administer jobs and alerts; automate (setup, maintenance, monitoring) across multiple databases and multiple instances; send to "Manage SQL Server Agent jobs"
Maintain Instances and Databases
  • Manage and configure databases.
    • This objective may include but is not limited to: design multiple file groups; database configuration and standardization: autoclose, autoshrink, recovery models; manage file space, including adding new filegroups and moving objects from one filegroup to another; implement and configure contained databases; data compression; configure Transparent Data Encryption (TDE); partitioning; manage log file growth; Database Console Commands (DBCC)
