質問 1：
An integration developer is developing a mediation module using the WebSphere Integration Developer. The mediation module interacts with different databases, via the database lookup mediation primitive and an Enterprise Information system (EIS) binding. It is expected that during the lifetime of this solution, the databases connection details will change. The customer wants to avoid downtime of the applications as much as possible. What is the BEST way for the integration developer to implement a solution so that when database connection details change, downtime is minimized?
A. Update the details of the database connections, then deploy the updated EAR file.
B. Define a properties file for the application to load on startup. When a change in the connection details occurs, update the details in the properties file and restart the application.
C. Define the various database connection details as WebSphere Variables. When a change in the connection details occurs, update the WebSphere Variables on the server and restart the server.
D. Define the various database connections used as JNDI names. When a change in the connection details occurs, update the JNDI details on the server and restart the application.
正解：D

質問 2：
An integration developer is using a Database Lookup primitive in a mediation flow. The developer wants to design the flow in such a way any connection failure in the Database Lookup primitive is persisted and then the message processing continues:
What is the correct way to achieve this in the flow? The developer must:
A. wire the keyNotFound terminal of the Database Lookup primitive to the input terminal of the Event Emitter mediation primitive; wire the output terminal of the Event Emitter mediation primitive to the next element in the flow.
B. wire the keyNotFound terminal of the Database Lookup primitive to the input terminal of the Fail mediation primitive; wire the output terminal of the Fail mediation primitive to the next element in the flow.
C. wire the fail terminal of the Database Lookup primitive to the input terminal of the Event Emitter mediation primitive; wire the output terminal of the Event Emitter mediation primitive to the next element in the flow.
D. wire the fail terminal of the Database Lookup primitive to the input terminal of the Fail mediation primitive; wire the output terminal of the Fail mediation primitive to the next element in the flow.
正解：A

質問 3：
An application containing a mediation flow has been deployed to a server. During runtime various faults are being seen in the server logs and the development team has been asked to investigate this issue.
On examination of the server logs, the team is having trouble locating where exactly in the flow the problems are occurring as the errors seem to be different each time. Examination of the mediation flow in WebSphere Integration Developer has shown that the flow currently does not have any error handling contained within it.
How should the developers BEST proceed in order to improve the flow error handling and to aid the debugging process following deployment?
A. Ensure that the Quality of Service transaction setting for the flow is set to Global.
B. Ensure the fail terminal of each primitive is wired with a Fail primitive containing a description
C. Use the Custom Mediation primitive to output extra logging information about the flow.
D. Use the Message Logger primitive to log messages so they can be examined.
正解：C

質問 4：
An integration development team is developing a mediation flow. A custom requirement is that in the event an error occurs at any point in the mediation flow, a copy of the entire SMO is to be placed into the server log for the system administrator to examine. How should the integration development team BEST implement this requirement?
A. Wire a Message Logger primitive to each failure terminal and set the Logging type to 'Local Server Log'.
B. Wire a Trace primitive to each failure terminal and set the destination property to 'Local Server Log'.
C. Wire a Custom primitive to each failure terminal and insert System.err.println(smo) into the Details section.
D. Change the server logging settings to log SMO messages.
正解：B

質問 5：
An integration developer needs to perform an iteration over an array of elements using the Fan Out - Fan In primitives.
Where in the Service Message Object (SMO) can the integration developer find the data of each occurrence of the repeating element?
A. In the primitive context section.
B. In the user context section.
C. In the body section.
D. In the shared context section.
正解：D

質問 6：
An integration developer must create an XML map to transform an input request to a back-end EIS request. Certain elements of the input request must be used as part of the back-end EIS request.
Which of the following values might be appropriate for the Root property of the transformation primitive?
A. "/headers"
B. "/context"
C. "/"
D. "/smo"
E. "/body"
正解：C

質問 7：
A service implementation has been exposed through an SCA Export binding. An integration developer drags the SCA Export of this service into the assembly diagram of a mediation module to integrate it with this service through an SCA Import binding. At this point, neither the service, nor the consuming mediation module is versioned. After deploying these modules in production, the integration developer decides to create multiple versions of the service with no change to the mediation module.
Which of the following statements is correct if the developer implements this change on the server? With multiple versions of the service, the import in the mediation module would:
A. resolve to only the oldest version of the export.
B. randomly pick up any version of the export to get bound to it.
C. resolve to only the latest version of the export.
D. fail to resolve to any export.
正解：C

質問 8：
An integration developer has created two versions of a component for debugging purposes. Which of the following statements BEST reflects the behavior of the two versions of the components in the integrated debugger?
A. The versions run sequentially in the integrated debugger.
B. The versions run in parallel in the integrated debugger.
C. The integrated debugger runs only the latest version of the component in debug mode.
D. The integrated debugger must be configured to run both versions in debug mode.
正解：B
