1. Correct Answer: A A. Correct: The sys.dm_exec_query_stats DMV returns aggregate performance statistics for cached query plans. These statistics include the usage of CPU and disk I/O resources. B. Incorrect: The sys.dm_db_index_physical_stats DMV returns size and fragmentation information for the data and indexes of the specified table or view. It does not return resource usage statistics. C. Incorrect: You can add Showplan event classes to a trace definition so that Profiler gathers and displays query plan information in the trace. This procedure does not return resource usage statistics. D. Incorrect: The sqlcmd utility allows you to enter commands, including operating system commands, by using the Command Console. It does not return resource usage statistics. 2. Correct Answer: C A. Incorrect: Restarting the SQL Server computer has an impact on database users. Resetting the statistics in the DMV has a minimal impact on users. B. Incorrect: Restarting the SQL Server service has an impact on database users. Resetting the statistics in the DMV has a minimal impact on users. C. Correct: The DMV statistics are cumulative. You need to reset them so that you can determine whether the readings relate to current performance problems. Resetting the DMV statistics has a minimal impact on users. D. Incorrect: The DMV statistics are cumulative. Inspecting the value in the waiting_tasks_count counter will not help you determine whether the DMV readings relate to current performance problems. You need to reset the statistics.

B. Correct: This query checks that the name starts with M without performing a substring operation. Data is case insensitive, so m% is the same as M% . C. Incorrect: Performing a substring operation to determine the first letter of a name is unnecessary and slows down the query. Duplicate rows probably do not exist and do not, in any case, present a problem, so the DISTINCT operator is unnecessary and slows query operation. D. Incorrect: Duplicate rows probably do not exist and do not, in any case, present a problem, so the DISTINCT operator is unnecessary and slows query operation. 2. Correct Answer: D A. Incorrect: Both Profiler and the DTA (especially the DTA) use server resources. Also, this procedure results in a series of recommendations. It does not quickly give you the information you need. B. Incorrect: This procedure lets you obtain recommendations for redesigning a query plan without executing the plan. However, this is not what you want to do. The DTA uses server resources, and you should not run it on a production server. Also, this procedure results in a series of recommendations. It does not quickly give you the information you need. C. Incorrect: This procedure gives you a graphical representation of the query plan. You can use the procedure to analyze a query plan without running the query, although it can also display information for a query you execute. It does not quickly give you the information you need. D. Correct: The DMV quickly gives you the information you need and does not add significantly to the load on the server. The disadvantage of using DMVs is that you need to execute the query, but that is not a problem in this case.

1. Correct Answer: B A. Incorrect: The ALTER INDEX statement with REORGANIZE replaces DBCC INDEXDEFR AG. In any case, you need to check the index for fragmentation, not reorganize it. B. Correct: You can use the system function sys.dm_db_index_physical_stats to detect fragmentation in a specific index, all indexes on a table or in an indexed view, all indexes in a database, or all indexes in all databases.
