第5题:
TestKing.com uses SQL Server 2005. Users report that report execution is slow. You investigate and discover that some queries do not use optimal execution plans. You also notice that some optimizer statistics are missing and others are out of date. You need to correct the problem so that reports execute more quickly. Which two Transact-SQL statements should you use?()
第6题:
It cannot generate recommendations that support multiple workload queries.
It can recommend partitioning on tables provided that the workloads have some predicates and joins on the columns of the NUMBER or DATE type.
It can recommend partitioning only on tables that have at least 10,000 rows.
It can recommend only B-tree indexes and not bitmap or function-based indexes
第7题:
Every SQL statement in the STS is considered only once for execution
The SQL statements in the STS are executed concurrently to produce the execution plan and execution statistics
The execution plan and execution statistics are computed for each SQL statement in the STS

第8题:
Run the SQL Access Advisor.
Run the SQL Tuning Advisor (STA).
Run the Automatic Workload Repository (AWR) report.
Run the Automatic Database Diagnostic Monitor (ADDM).
第9题:
The plan baselines can be evolved over time to produce better performance.
The newly generated plans are directly placed into the SQL plan baseline without being verified.
The new SQL statements initially run with the plans that are known to produce good performance under standard test configuration.
The optimizer does not generate new plans for the SQL statements for which the SQL plan baseline has been imported.
