You are the administrator of a SQL Server 2000 computer. The server contains a database named FinanceData that is used by a client/server application. Each employee has a SQL Server login that the application uses to access the server.Your company hires a new employee named Andrew. You create a SQL Server login named Andrew. You also create a database user named Andrew in the database and grant the database user full permissions in the database.Whenever Andrew runs the client/server application, he receives the following error message: "Invalid object name." Andrew also reports that he cannot access the database by using the application.You need to ensure that Andrew can use the application. Which Transact-SQL statement should you execute?

A

EXEC sp_defaultdb 'Andrew','FinanceData'

B

GRANT ALL ON FinanceData TO Andrew

C

EXEC sp_addlogin 'Andrew'

D

EXEC sp_grantdbaccess 'FinanceData','Andrew'GOsp_addrolemember 'db_datareader','Andrew'

Which of the following statements are true?
Statement I Big data refers to no precise quantity, but generally refers to data in the range of Petabytes and Exabyte, i.e. billions to trillions of records, all from various sources. Big data is generated much faster. than traditional data in much larger quantities.
Statement II Big data interests industries because they are able to learn more patterns and curious variances than smaller data sets, with the capability to provide valuable insights into consumer behaviour, weather systems, financial market activity, or other phenomena.
Statement III Various departments and product lines use various applications within most organisations and store data in separate datasets. These separate databases may contain similar data, but data from one data base to another is not always consistent. This is called data silo.

You are a Web developer for XYZ. You create an ASP.NET application that accesses sales and marketing data. The data is stored in a Microsoft SQL Server 2000 database on a server named XYZ01.
The company purchases a factory automation software application. The application is installed on XYZ01, where it creates a second instance of SQL Server 2000 named Factory and a database named FactoryDB. You connect to FactoryDB by using Windows Integrated authentication.
You want to add a page to your ASP.NET application to display inventory data from FactoryDB. You use a SqlConnection object to connect to the database. You need to create a connection string to FactoryDB in the instance of SQL Server named Factory on XYZ01. Which string should you use?

A

?Server=XYZ01;Data Source=Factory; Initial Catalog=FactoryDB;Integrated Security=SSPI?

B

?Server=XYZ01;Data Source=Factory; Database=FactoryDB;Integrated Security=SSP1?

C

?Data Source=XYZ01\\Factory; Initial Category=Factory; Integrated Security=SSP1?

D

?Data Source=XYZ01\\Factory; Database=FactoryDB; Integrated Security=SSP1?

You are an administrator of a SQL Server 2000 computer. The server contains a database that stores inventory data. Another database administrator has created a number of scheduled jobs to maintain the inventory database. Each weeknight the following jobs occur.
- A BULK INSERT job imports data at 10:00 P.M
- Indexes are rebuilt at 10:15 P.M
- Data integrity checks are performed at 10:30 P.M
- A differential backup is performed at 10:45 P.M
- A DBCC SHRINKDATABASE job runs at 11:00 P.M.
You notice that the final job often fails and returns the following error message: "Server: Msg 3140, Level 16, State 3. Could not adjust the space allocation for file 'inventory_data'."You need to ensure that the final job runs without errors. What should you do?

A

Modify the DBCC SHRINKDATABASE job so that it uses DBCC SHRINKFILE statement to shrink each file individually.

B

Create a new DBCC SHRINKFILE job to shrink the inventory_data file. Schedule the new job to run at the same time as the DBCC SHRINKDATABASE job.

C

Increase the time between the differential backup and the DBCC SHRINKDATABASE job.

D

Increase the time between the data integrity checks and the differential backup.

You are the database administrator for a financial services company. Employees enter data 24 hours a day into a SQL Server 2000 database. These employees report slower response times when new account information is gathered from branch offices and added to the database. You currently use the following BULK INSERT statement to add the account information.BULK INSERT finance.dbo.customersFROM 'd:bulkaccts143_10142000.txt'WITH DATAFILETYPE = 'char', FIELDTERMINATOR = 't', ROWTERMINATOR = 'n', TABLOCK You want to ensure that response times do not slow when new account information is added to the database. What should you do?

A

Add the BATCHSIZE option to the BULK INSERT statement, and then set the option equal to 10 percent of the number of rows to be loaded.

B

Add the ROWS_PER_BATCH option to the BULK INSERT statement, and then set the option equal to 10 percent of the number of rows to be loaded.

C

Drop the indexes for the Customers table before the data load, and then re-create the indexes after the data load is complete.

D

Remove the TABLOCK option from the BULK INSERT statement.

You develop an enterprise application, called XYZApplication that includes a Windows Form presentation layer, middle-tier components for business logic and data access, and a Microsoft SQL Server database.
You are in the process of creating a middle-tier component that will execute the data access routines in your application. When data is passed to this component, the component will call several SQL Server stored procedures to perform database updates. All of these procedure calls run under the control of a single transaction.
The code for the middle-tier component will implement the following objects:
SqlConnection cn = new SqlConnection();
SqlTransaction tr;
If two users try to update the same data concurrently, inconsistencies such as phantom reads will occur. You must now add code to your component to specify the highest possible level of protection against such inconsistencies.
Which code segment should you use?

A

tr = cn.BeginTransaction(?ReadCommitted?);

B

tr = cn.BeginTransaction(IsolationLevel.ReadCommitted);

C

tr = cn.BeginTransaction(IsolationLevel.Serializable);

D

tr = cn.BeginTransaction(?Serializable?);
