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

Starting 24 April 2014, the questions on this exam include content covering SQL Server 2014.

Please note that the questions may test on, but will not be limited to, the topics described in the bulleted text.

Implement database objects (30-35%)

Create and alter tables (complex statements)
Develop an optimal strategy for using temporary objects, including table variables and temporary tables; define alternatives to triggers; define data version control and management; implement @Table and #table appropriately; create calculated columns; implement partitioned tables, schemas and functions; implement column collation; implement online transaction processing (OLTP)

Design, implement and troubleshoot security

Design the locking granularity level
Choose the right lock mechanism for a given task; handle deadlocks; design index locking properties; fix locking and blocking issues; analyse a deadlock scenario; design appropriate isolation level, including Microsoft ActiveX data objects defaults; design for locks and lock escalation; design transactions that minimise locking; reduce locking contention; identify bottlenecks in data design; design appropriate concurrency control, such as pessimistic or optimistic

Maintain indexes
Inspect physical characteristics of indexes and perform index maintenance, identify fragmented indexes, identify unused indexes, implement indexes, defrag/rebuild indexes, set up a maintenance strategy for indexes and statistics, optimise indexes (full, filter index), statistics (full, filter), force or fix queue, when to rebuild versus reorg and index, create a tuning and maintenance strategy for proactive operations
