You are a database developer for a container manufacturing company. The containers produced by your company are a number of different sizes and shapes. The tables that store the container information are shown in the Size, Container, and Shape Tables exhibit:SizeSizeIDSizeNameHeightContainerContainerIDShapeIDSizeIDShapeShapeIDShapeNameMeasurementsA sample of the data stored in the tables is shown below:Size TableSizeID SizeName Height1 Small 402 Medium 603 Large 804 Jumbo 100Shape TableShapeID ShapeName Measurement1 Triangle 102 Triangle 203 Triangle 304 Square 205 Square 306 Square 407 Circle 158 Circle 259 Circle 35Periodically, the dimensions of the containers change. Frequently, the database users require the volume of a container. The volume of a container is calculated based on information in the shape and size tables.You need to hide the details of the calculation so that the volume can be easily accessed in a SELECT query with the rest of the container information. What should you do?A. Create a user-defined function that requires ContainerID as an argument and returns the volume of the container.B. Create a stored procedure that requires ContainerID as an argument and returns the volume of the container.C. Add a column named volume to the container table. Create a trigger that calculates and stores volume in this column when a new container is inserted into the table.D. Add a computed column to the container table that calculates the volume of the container.

Periodically, the dimensions of the containers change. Frequently, the database users require the volume of a container. The volume of a container is calculated based on information in the shape and size tables.
You need to hide the details of the calculation so that the volume can be easily accessed in a SELECT query with the rest of the container information. What should you do?
A. Create a user-defined function that requires ContainerID as an argument and returns the volume of the container.
B. Create a stored procedure that requires ContainerID as an argument and returns the volume of the container.
C. Add a column named volume to the container table. Create a trigger that calculates and stores volume in this column when a new container is inserted into the table.
D. Add a computed column to the container table that calculates the volume of the container.

You are a database administrator in the Los Angeles branch office of a specialty foods supplier. A mainframe. database at the headquarters contains all company data. Each branch office contains a SQL Server 2000 computer that imports regional data from the mainframe. database.The server in Los Angeles contains a Data Transformation Services (DTS) package that uses OLE DB to connect to the company's mainframe. database. The DTS package extracts and transforms data about buyers and products for that region. The DTS package then writes the data to the SQL Server database in Los Angeles.You need to configure a SQL Server computer for the new branch office in Sydney. You want to copy the Los Angeles package and modify it so that it writes data to the SQL Server database in Sydney.You use the DTS Designer to modify the DTS package so that it imports regional data from the mainframe. database to the server in Sydney. The modified DTS package runs successfully on the server in Los Angeles. You save this DTS package to the server in Sydney, but the server in Sydney cannot connect to the mainframe. database.You want to enable the server in Sydney to connect to the mainframe. database. What should you do?A．Change the connection properties in the DTS package so that the package uses new login credentials to connect to the mainframe. database.B．Modify the workflow in the DTS package so that the server in Sydney is included.C．On the server in Sydney, install an OLE DB provider for the mainframe. database.D．On the server in Sydney, delete and then re-create the DTS package.
