Q21. An organization has a large investment in legacy technologies (such as CICS and IMS) supporting applications that provide their core business transactions and data access. The Solution Architect believes significant value exists in providing interoperable or open standard,service-based access to those transactions (e.g., transactions that query account balance, create orders, schedule or track deliveries, query stock levels.)
Which solution pattern should be considered by an Architect for providing service-based access tolegacy systems?
A. Create a data access component for each transaction.
B. Implement a service choreographer.
C. Add a controlling service gateway.
D. Implement an infrastructure with a Web services-compliant broker.
Answer: D
Q22. A mortgage loan provider currently has legacy applications utilized by a networkof branches and franchised agents. They want to expand by adding a new channel to allow independent mortgage brokers to submit mortgage loan applications. They realize they must provide a differentiating offering to the independent mortgage brokers to attract participants and grow the new channel.
How can SOA benefit their requirement?
A. By building an SOA with a secure connectivity layer, they could quickly enable the mortgage broker channel to use their applications without any changes to the legacysystem.
B. They could reduce the cost to develop new applications needed for each independent broker by reusing services as integration code that is written for each broker's system to expedite development.
C. By service enabling the legacy applications and offering a Web-based portal for independent brokers, they can minimize the impact to existing channels, minimize changes to existing code, and quickly create an offering for the new channel.
D. By implementing security and governance as part of an SOA deployment, they can control access to the current system to determine which brokers are using the system and personalize their marketing to the high usage brokers.
Answer: C
Q23. Why is it necessary to enforce policies and monitor services within SOA Services Management?

Q24. A financial services company manages retirement accounts for its corporate clients. The company has developed Web services for account and portfolio management and has deployed an Enterprise Service Bus (ESB) to mediate access to the servicesfrom various internal applications.
Recently, the company has been getting pressure from some of its clients to expose its account and portfolio Web services externally so that clients can consume and integrate these services within their own internalWeb applications. The company wants to ensure that access to the services by its clients is secure and controlled so that accounts are not compromised and also wants to minimize impact to its current IT infrastructure. The company consults an SOA Designerfor guidance on the solution design.
Which approach should the SOA Designer suggest to handle this requirement?
A. Allow clients access to the services via a portal that exposes only those services applicable to each client.
B. Create a business processto route client requests to the appropriate services based on business rules.
C. Allow service access to clients via an exposed ESB gateway that restricts access to authorized requestors only.
D. Update the existing mediation logic in the ESB to handle the security requirements and allow external applications to access the services.
Answer: C

A. Information Services
B. Process Services
C. Partner Services
D. Interaction Services
Answer: C
Q26. A company has multiple services with each having adifferent requirement for availability and response time.
Which environment should the Architect recommend?

Q27. A company is using the IBM SOA Solution Stack to create a new composite application to keep up with the changing marketplace. Functions and data from several existing Enterprise Information Systems (EIS) will be aggregated into the new application using a top-down approach. See the information in the Exhibit.
Which solution is the most appropriate for implementation?
A. Exposing existing applications using multiple adapters
B. Exposing existing systems to heterogeneous clients
C. Exposing existing applications with service components
D. Exposing existing systems with a Web services gateway
Answer: C
Q28. How can a designer most effectively integrate components developed in various technologies at different companies into a composite application within an SOA?
A. Through careful coordination to ensure compatible interfaces
B. Through the use of industry standards such as SOAP over HTTPS
C. By placing the components in a service repository which will mediate the differences in their interfaces
D. By providingcode mediation and transformation functions through a business process modeling effort
Answer: B
Q29. Due to a number of recent acquisitions, an organization is reviewing common services provided by each of the acquired companies to reduce duplication. As part of this review, they discover functionally equivalentservices deployed by all of the different organizations.
Which technique provides valuable feedback from operations about which duplicate services most completely meet non-functional requirements of the service?
A. Use business modeling tools to drive process simulations based on operational data.
B. Use an integrated systems management console with an integrated capacity planning tool.
C. Use a business activity monitor dashboard with Service Level Agreement (SLA) templates and policies to monitor and analyze KPIs.
D. Use the metadata and usage information from the service registry to determine service usage.
Answer: B
Q30. As part of an SOA initiative, a utility company is re-writing a 2-tier call center application used for reporting power outages. Customers call in to report power outages and in some cases ask to be notified when the problemis fixed. The call center application is tightly coupled with a vendor-developed power management application which dispatches workers for repairs. The current call center application is difficult to maintain since it implements a very large and complex framework to manage the calls and the relationship with the power management system.
Which design approach should the SOA Designer use?
A. Expose the API of the existing application framework as a collection of services.
B. Enhance the existing application framework with a portal to provide integration at the glass.
C. Ask the power management software vendor to create Web services access.
D. Replace the existing application framework with an Enterprise Service Bus (ESB) and an adapter to the power management system.
