What should you use?
- Activity Monitor
- sp_who3 stored procedure
- SQL Server Management Studio (SSMS) Object Explorer
- SQL Server Data Collector
- SQL Server Data Tools (SSDT)
- SQL Server Configuration Manager
Correct answer: B
Explanation:
Use sp_who3 to first view the current system load and to identify a session of interest. You should execute the query several times to identify which session id is most consuming teh system resources. Parameters sp_who3 null - who is active; sp_who3 1 or 'memory' - who is consuming the memory; sp_who3 2 or 'cpu' - who has cached plans that consumed the most cumulative CPU (top 10); sp_who3 3 or 'count' - who is connected and how many sessions it has; sp_who3 4 or 'idle' - who is idle that has open transactions; sp_who3 5 or 'tempdb' - who is running tasks that use tempdb (top 5); and, sp_who3 6 or 'block' - who is blocking. Use sp_who3 to first view the current system load and to identify a session of interest. You should execute the query several times to identify which session id is most consuming teh system resources.
Parameters
sp_who3 null - who is active;
sp_who3 1 or 'memory' - who is consuming the memory;
sp_who3 2 or 'cpu' - who has cached plans that consumed the most cumulative CPU (top 10);
sp_who3 3 or 'count' - who is connected and how many sessions it has;
sp_who3 4 or 'idle' - who is idle that has open transactions;
sp_who3 5 or 'tempdb' - who is running tasks that use tempdb (top 5); and,
sp_who3 6 or 'block' - who is blocking.

You observe that several indexes are fragmented.
You need to rebuild the indexes.
What should you use?
- Activity Monitor
- sp_who3 stored procedure
- Object Explorer in the SQL Server Management Studio (SSMS)
- SQL Server Data Collector
- SQL Server Data Tools (SSDT)
- SQL Server Configuration Manager
Correct answer: C
Explanation:
How to: Rebuild an Index (SQL Server Management Studio)To rebuild an index In Object Explorer, connect to an instance of the SQL Server Database Engine and then expand that instance. Expand Databases, expand the database that contains the table with the specified index, and then expand Tables. Expand the table in which the index belongs and then expand Indexes. Right-click the index to rebuild and then click Rebuild. To start the rebuild operation, click OK.
