1. Both symmetric and asymmetric encryption can meet the requirements, but symmetric encryption is the best choice because it minimizes administrative overhead. You can use symmetric key encryption because the data will be transferred between relatively stable computers in remote offices, and because configuring each with a secret key would be easy. Alternatively, you can use asymmetric encryption, configure a key pair at the centralized database, and distribute the public key to each of the remote offices. The application could then use asym-

Automatic Updates is also the client component of a Software Update Services (SUS) infrastructure, which allows an enterprise to provide centralized and managed updates..

If a damaged table has one or more constraints, it is recommended that you run DBCC CHECKCONSTRAINTS when the repair operation is complete. In some cases, the damage might be so severe that there is not enough information to repair the database. To gain limited access to the remaining data, it will be necessary to place the database into emergency mode. You can accomplish this by using the EMERGENCY option of the ALTER DATABASE command. EMERGENCY mode allows members of the sysadmin fixed server role read-only access. This allows them to diagnose problems and retrieve any available data.

In the Notifications and Filters sections, you can perform the following actions:

1. Correct Answers: B and D A. Incorrect: You cannot enable the CLR on a database-by-database basis. B. Correct: The CLR must be enabled using the Surface Area Configuration utility. C. Incorrect: A class that conforms to the UDT specification must be com piled and loaded into SQL Server; however, class creation is not limited exclusively to .NET languages. D. Correct: Any CLR-compatible language, which includes C#, Visual Basic, and Cobol.NET can be used to create a class to be used for a CLR UDT. 2. Correct Answers: A and C A. Correct: System functions that return a scalar value can be referenced. B. Incorrect: Stored procedures cannot be called within a check constraint. C. Correct: UDFs that return a scalar value can be referenced. D. Incorrect: Views cannot be referenced in check constraints. 3. Correct Answer: C A. Incorrect: A text data type can store up to 2 GB of data, but does not allow direct comparison of columns. B. Incorrect: A varbinary data type stores binary data. C. Correct: A varchar(max) column can store up to 2 GB of data while still allowing all functions and comparison operators to be used. D. Incorrect: A regular varchar column cannot store 2 GB of data. 4. Correct Answer: B A. Incorrect: A text data type is always inappropriate for a primary key because of the possibility of having very large volumes of data stored in the column.

In 1, you started SQL Server Profiler, captured a trace generated by running a query from the Query Editor, and then used that trace as a workload in the DTA. If you prefer, you can enter a query or procedure into Query Editor and use the Analyze Query In Database Engine Tuning Advisor button on the Query Editor toolbar to open the DTA and provide either all or a selected portion of the code in the Query Editor window as a workload for DTA analysis. We discuss the DTA later in this lesson.
