An application receives a batch of order records that are needed to populate a database. An order record is received that will cause an insert into the database table. Subsequent records will update this record. It is important that the: ?insert record is processed first. ?updates are processed so that the order record has the correct information at the end of processing. ?If update 1 changes the quantity from 5 to 20. ?If update 2 changes the quantity from 20 to 11. ?If update 2 is processed before update 1, the order quantity will no longer be correct. Which of the following quality of service (QoS) qualifiers should the integration developer use?
A. Add the Event Sequencing qualifier to the implementation of the component.
B. Add the Join Activity Session qualifier to the interface of the component.
C. Add the Join Transaction qualifier to the interface of the component.
D. Add the Event Sequencing qualifier to the interface of the component.
正解：D

質問 2：
An integration developer uses the Process Center perspective to connect to a repository. The Process Center repository contains process applications and toolkits which members of the business development team designed. The integration developer has ProcAppA open in an Integration Designer workspace. In order to run the process application on the repository, the integration developer must: (choose two)

B. create a new snapshot of the process application.
C. create a new import component which implements the interface.
D. call the invoke operation on the interface.

正解：C,D

質問 3：
During acceptance testing of an integration solution, various errors in the mediation flows were discovered. While correcting these errors, the development team found that little or no error handling was present within the mediation flows. Therefore, a new requirement is introduced to handle every exception within any mediation flow in exactly the same way by logging the exception to a file. How can an integration developer implement this requirement?
A. Create a mediation flow containing the exception handling logic, and invoke it whenever an error occurs.
B. Create a mediation subflow containing the exception handling logic, and connect every fail terminal to this new subflow.
C. Connect a trace primitive to each fail terminal.
D. Create a mediation subflow containing the exception handling logic, and connect the error input node of each mediation flow to this new subflow.
正解：D
