000-665 IBM Architectural Design of SOA Solutions
Answer: D QUESTION:52 An SOA solution designer has been asked to review a customer's service implementation. The customer has implemented a stateful service which models an interaction with three consecutive steps. What is the best advice to give the customer? A. Services should not be stateful. B. Service components should ideally hold state in-memory to avoid unnecessary overheads. C. State required by the service should be passed back and forth to the service consumer. D. The interaction should be modeled as a BPEL process and deployed on IBM Process Server. Answer:C QUESTION:53 A company has a heterogeneous set of service-enabled and legacy applications deployed internally. Currently, user accounts are managed differently by each application and a user needs to authenticate using different user ID'S for different applications. This results in relatively high IT support and maintenance costs since the IT department must set up most of the application user accounts manually and there is a proliferation of extraneous user accounts across the IT systems. The company wants to address this issue by creating a unified user management system where the IT department can centrally manage users in the enterprise, including their credentials and roles.The solution should also automatically provision user accounts to various applications based on the user's role in the organization. Which of the following IBM SOA Foundation offerings is best suited to address these requirements?
