In the open systems interconnection (OSI) reference model, "layer" means one of seven conceptually complete,(71) arranged groups of services, functions, and protocols, that extend across all open systems.Application layer provides means for the application(72) to access the OSI environment. Presentation layer provides for the selection of a common syntax for representing data.(73) layer provides the means necessary for cooperating presentation entities to organize and synchronize their dialog and to manage their data exchange. Transport layer provides a reliable end-to-end data transfer service. Network layer provides for the entities in the transport layer the means for transferring blocks of data, by(74) and switching through the network between the open systems in which those entities reside. Data link layer provides services to transfer data between network layer entities. Physical layer provides the mechanical, electrical, functional, and procedural means to establish, maintain and(75) physical connections for transfer of bits over a transmission medium.A．ranklyB．levellyC．layeredD．hierarchically

You are the administrator of a SQL Server 2000 computer. The server contains a database that stores financial data. You want to use Data Transformation Services packages to import numeric data from other SQL server computers. The precision and scale values of this data are not defined consistently on the other servers.You want to prevent any loss of data during the import operations. What should you do?A．Use the ALTER COLUMN clause of the ALTER TABLE statement to change data types in the source tables. Change the data types so that they will use the lowest precision and scale values of the data that will be transferred.B．Use the ALTER COLUMN clause of the ALTER TABLE statement to change data types in the destination tables. Change the data types to reflect the highest precision and scale values involved in data transfer.C．Set a flag on each DTS transformation to require an exact match between source and destination columns.D．Set the maximum error count for each DTS transformation task equal to the number of rows of data you are importing. Use an exception file to store any rows of data that generate errors.E．Write Microsoft ActiveX script. for each DTS transformation. Use the script. to recast data types to the destinations precision and scale values.
