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
USER_DATA is a nonencrypted tablespace that contains a set of tables with data. You want to convert all existing data in the USER_DATA tablespace and the new data into the encrypted format.Which methodswould you use to achieve this?（）A. Use Data Pump to transfer the existing data to a new encrypted tablespaceB. Use ALTER TABLE MOVE to transfer the existing data to a new encrypted tablespaceC. Use CREATE TABLE AS SELECT to transfer the existing data to a new encrypted tablespaceD. Enable row movement for each table to be encrypted and then use ALTER TABLESPACE to encrypt the tablespaceE. Encrypt the USER_DATA tablespace using the ALTER TABLESPACE statement so that all the data in the tablespace is automatically encrypted
Which statement is true about a running session that belongs to the online transaction processing (OLTP) group?() A. It permanently switches to the low_group consumer group if the session exceeds 10,000 I/O requests or 2,500 MB of data transfer.B. It performs the first 10000 I/O requests or 2,500 MB of data transfer in the LOW-GROUP consumer group, and then switches to the original group.C. It switches to the LOW_GROUP consumer group if the session exceeds 10000 I/O requests or 2500 MB of data transfer and returns to the original group after the operation.D. It switches to the LOW_GROUP consumer group if the session exceeds 10000 I/O requests or 2500MB of data transfer for queries, but not for data manipulation language (DML) operations.

The "main storage" normally means that part of internal storage into which instructions and other data must be loaded for subsequent execution or processing. In large computing systems, the term "main storage" is(71) to "memory". "Buffer" mainly indicates a special-purpose storage or storage area allowing, through(72) storage, the data transfer between two functional units having different transfer characteristics. A buffer storage is used between non-synchronized devices or where one is(73) and the other is parallel or between those having different trans far rates. "(74) (memory)" is also a special-purpose buffer storage, smaller and faster than main storage, used to hold a copy of instructions and data obtained from main storage and likely to be needed next by the processor. "Register" is commonly composed of a part of internal storage having a specified storage(75) and usually intended for a specific purpose.A．suitableB．optionalC．choiceD．preferred

单选题Which of the following statements is correct concerning heat transfer?（）AHeat is given off from a high temperature region known as a heat sinkBHeat transfer rate is affected most by the size of the heat sink involvedCHeat transfer rate is affected most by the temperature difference between the heat source and the heat sinkDHeat transfer by radiation will occur only by mass motion of a fluid substance
单选题What is the architectural benefit of keeping WebLogic Server transaction log in the database?（）AOracle does not allow replicating files between data centers, so keeping transaction log in database allows for replication.BMany transactions in WebLogic are database centric, so keeping log in database makes Two Phase Commit protocol possible.CIt obviates the need to keep in sync two replication technologies (file and database) between data centers. The single replication technology is used for frequently changing data.DTransaction log in a file system is extremely slow so it cannot be efficiently replicated.
