What should you implement to optimize SQL Database for Race Central to meet the technical requirements?
A. the sp_update stored procedure
B. automatic tuning
C. Query Store
D. the dbcc checkdb command
Correct Answer: A
Explanation/Reference:
Explanation:
Scenario: The query performance of Race Central must be stable, and the administrative time it takes to perform optimizations must be minimized. sp_updatestats updates query optimization statistics on a table or indexed view. By default, the query optimizer already updates statistics as necessary to improve the query plan; in some cases you can improve query performance by using UPDATE STATISTICS or the stored procedure sp_updatestats to update statistics more frequently than the default updates.
Incorrect Answers:
D: dbcc checkdchecks the logical and physical integrity of all the objects in the specified database References:
