Q47. A large machinemanufacturing company is using WebSphere Message Broker as an Enterprise Service Bus (ESB) providing routing and transformation functions. Manufacturing data is available from MQ enabled CICS transactions. Customer information is available via existing Webservices on WebSphere Process Server (WPS) accessing UDB via JDBC. They are developing a new service to track the status of a customer's specific machine through production. The SOA Designer has decided to first create a Manufacturing Information serviceon WPS using JMS to access the CICS transactions.
What is the rationale for this approach?
A. Reusability
B. Reliability
C. Portability
D. Data Consistency
Answer: A
Q48. A government department has been directed to make sure that its agencies can share data sothey can handle crises effectively. Laboring under a prior directive to migrate to SOA, the Chief Architect is looking for the best way to incorporate this latest directive.
What should the SOA Designer recommend?
A. The various agency databases shouldbe federated and information services implemented. The data transformation capabilities are included in data federation.
B. New data replication processes should be introduced so that information within agency databases can be shared whenever needed. Datatransformation should be incorporated within the replication processes where there is a mismatch.
C. Enterprise Service Bus (ESB) message transformations should be used to transform exchanged data based on agency standard data models. Existing messages should be converted into XML so that SOA appliances can use XSLT to convert the messages at high speed.
D. Business experts and IT data modelers should develop an enterprise level standard data model. Each agency can then define how its data can be convertedinto the standard. Once done, Extract/Transform/Load ETL tooling can be used for large scale cleansing of the existing databases and transforming it into the new standard.
