sys.dm_io_virtual_file_stats Returns I/O statistics for data and log files.

If we are going to encrypt credit card number for storage, then we should have Data Encryption Key(DEK) for encrypting the credit card number.

- Scenario: Databasel will also contain a stored procedure named usp_UpdateOrderDetails.  The stored procedure is used to update order information. The stored procedure queries the Orders table twice each time the procedure executes.  The rows returned from the first query must be returned on the second query unchanged along with any rows added to the table between the two read operations. - REPEATABLE READ Specifies that statements cannot read data that has been modified but not yet committed by other transactions and that no other transactions can modify data that has been read by the current transaction until the current transaction completes.

Scenario: The databases must be available if the SQL Server service fails.

- Scenario: Database2 will contain a stored procedure named usp_UpdateInventory. Usp_UpdateInventory will manipulate a table that contains a self-join that has an unlimited number of hierarchies. - A table variable can be very useful to store temporary data and return the data in the table format. - Example: The following example uses a self-join to find the products that are supplied by more than one vendor. Because this query involves a join of the ProductVendor table with itself, the ProductVendor table appears in two roles. To distinguish these roles, you must give the ProductVendor table two different aliases (pv1 and pv2) in the FROM clause.  These aliases are used to qualify the column names in the rest of the query. This is an example of the self-join Transact-SQL statement:           Incorrect Answers:B: Using a CTE offers the advantages of improved readability and ease in maintenance of complex queries.The query can be divided into separate, simple, logical building blocks.  These simple blocks can then be used to build more complex, interim CTEs until the final result set is generated

Dynamic Management Views and Functions (Transact-SQL)

- Scenario:- Data from Database2 will be accessed periodically by an external application named Application1 - Application developers must be denied direct access to the database tables.  Applications must be denied direct access to the tables. Tutorial: Signing Stored Procedures with a Certificate

- Scenario: You must encrypt the backup files to meet regulatory compliance requirements.  The encryptionstrategy must minimize changes to the databases and to the applications. - Transparent data encryption (TDE) performs real-time I/O encryption and decryption of the data and log files. The encryption uses a database encryption key (DEK), which is stored in the database boot record for availability during recovery. Transparent Data Encryption (TDE)

- EXECUTE AS Clause (Transact-SQL) In SQL Server you can define the execution context of the following user-defined modules: functions (exceptinline table-valued functions), procedures, queues, and triggers.

1. Scenario: System administrators must be able to run real-time reports on disk usage.2. The data collector provides an historical report for each of the System Data collection sets.  Each of the following reports use data that is stored in the management data warehouse:Disk Usage Summary Query Statistics History Server Activity History You can use these reports to obtain information for monitoring system capacity and troubleshooting system performance.
