You create a stored procedure that retrieves all of the rows from a table named Table1.
You need to recommend a solution to ensure that all of the statements in the stored procedure can be executed if another transaction is modifying rows in Table1 simultaneously.
What should you recommend?
A. Snapshot isolation
B. A database snapshot
Once snapshot isolation is enabled, updated row versions for each transaction are maintained in tempdb. A unique transaction sequence number identifies each transaction, and these unique numbers are recorded for each row version. The transaction works with the most recent row versions having a sequence number before the sequence number of the transaction. Newer row versions created after the transaction has begun are ignored by the transaction.
You have a SQL Server instance on a server named Server1.
You need to recommend a solution to perform the following tasks every week:
– Rebuild the indexes by using a new fill factor.
– Run a custom T-SQL command.
– Back up the databases.
What should you recommend?
More than one answer choice may achieve the goal. Select the BEST answer.
A. A trigger
B. An alert
C. A maintenance plan
D. Windows PowerShell
E. A system policy
Maintenance plans create a workflow of the tasks required to make sure that your database is optimized, regularly backed up, and free of inconsistencies.
