If a computer is shut down suddenly, the security database can become corrupted. If the security database becomes corrupted, perform the following steps to repair it: 1. At the command prompt, run esentutl /g to check the integrity of the security database. The database is found at %windir%\Security\Database\secedit.sdb. 2. If the database is corrupt, change to the %windir%\Security folder and run esentutl /r. 3. If this does not work, run esentutl /p against %windir%\Security\Database\secedit.sdb. 4. If none of the previous three steps work, delete all log files located in %windir%\Security.

Exercise 2: Test Using a Large Result Set In this exercise, you will execute the three queries mentioned in the lab preface and record each query s cost. In this case, the parameter supplied to all three queries (TerritoryID) will yield a larger result set of 3,433 rows (compared to 64 rows in the previous exercise). 1. Open SQL Server Management Studio and connect to an instance of SQL Server 2005. 2. In a new query window, type and execute the following SQL statements to create the TestDB database, the Test schema, and the two tables that will be used in this exercise:

from the Coho Vineyard Web site. Employees in each winery must be able to enter data locally in a Web application and have that data immediately written to databases on the database server at the central office. Finally, users must also be given a func tional e-mail account within the cohovineyard.com domain. This e-mail server must be located at the central office.

The database server should rely on the Kerberos protocol to authenticate Coho Vineyard employees. Coho Vineyard customers should not be given a Windows user account. One employee from each vineyard should be designated as an adminis trator of the DB1 database server.

StartTime, EndTime, ApplicationName, NTUserName, and LoginName are optional. You require DatabaseID only if you are accessing more than one database. Information in the Duration and TextData columns is especially useful in this analysis. Typically, you filter the trace to exclude system events and events with a duration of less than, for example, 5000 (5 seconds).

1. How can you meet the technical requirements for SQL Server authentication (Choose all that apply.) A. Configure DB1 to use SQL Server and Windows authentication mode. B. Configure DB1 to use Windows authentication mode. C. Create a Web application that collects customer credentials and matches these credentials to a SQL Server login. D. Create a Web application that collects employee credentials and matches these credentials to a SQL Server login. 2. How should you assign privileges to database server administrators A. Add the domain user accounts of one employee from each vineyard to the sysadmin fixed server role on DB1. B. Create a DB1Admins global group in the cohovineyard.com domain. Add the domain user account of one employee from each vineyard to the DB1Admins group and then add the DB1Admins group to the sysadmin fixed server role on DB1. C. Add the SQL Server logins of one employee from each vineyard to the sysadmin fixed server role on DB1. D. Create a DB1Admins global group in the cohovineyard.com domain. Add the SQL Server logins of one employee from each vineyard to the DB1Admins group and then add the DB1Admins group to the sysadmin fixed server role on DB1. 3. You are concerned that certain unauthorized employees have been directly added as DB1 system administrators. After you connect to the database with the user s login, how can you verify whether a given user is a system administrator of DB1 A. The SQL statement SELECT IS_SRVROLEMEMBER( serveradmin ) returns a value of zero. B. The SQL statement SELECT IS_SRVROLEMEMBER( sysadmin ) returns a value of zero. C. The SQL statement SELECT IS_SRVROLEMEMBER( serveradmin ) returns a value of 1. D. The SQL statement SELECT IS_SRVROLEMEMBER( sysadmin ) returns a value of 1.
