Question 9


Answers D and E are correct. Both performing a query against sys.dm_db_index_physical_stats and checking the fragmentation page of the index from within SQL Server Management Studio allow you to see fragmentation as well as many other physical characteristics. While querying sys.dm_fts_indexpopulation returns information about the full-text index populations currently in progress, sys.dm_exec_query_stats returns aggregate performance statistics for cached query plans.
