問題1

It has come to your notice that there is little or no reuse of SOA Services in production. After some investigation, you have been made aware that project development teams are struggling with Service interoperability challenges.
What course of action do you take to address these challenges?

A. Design-time governance quality points are employed to ensure that Services following agreed enterprise standards and guidelines.

B. A single registry is employed to ensure Services are consistently published.

C. A single technology (for example, Java) is employed to build all Services which ensure standards consistency.

D. A single repository is employed to ensure Services are consistently discoverable.

E. A single service engineering team is employed to build all Services which ensure implementation consistency.

正確答案: B

問題2

You receive non-functional requirements for a set of business Services which specify that the Service must deliver secure payloads. In addition, the Services need to be built whereby they promote reusability, especially in heterogeneous IT environments. Which option best describes how you would design the Service?

A. Use Java.security to encrypt payload while making sure that service consumers are on a secure and reliable network.

B. Use WS-Policy and WS-Reliable Messaging to support delivery-based quality of service.

C. Use WS-I to promote interoperability while using the WS-Security family of services to secure web services.

D. Use Java to build the service and SSL to encrypt the transport.

正確答案: B

問題3

Which two statements are valid SOA infrastructure principles?

A. SOA Infrastructure must be based on open standards. This supports a best-of-breed approach and prevents vendor lock in.

B. Multiple versions of a SOA Service must not be run concurrently.

C. SOA infrastructure must be designed to enable point-to-point integration.

D. SOA Infrastructure must support all Services with standards-based interfaces, regardless of their choice of implementation technology.

問題4

Which statements describe how the Mediation Layer relates to the other architecture layers In the service-oriented integration architecture?

A. The Mediation Layer enables connectivity to back-end systems by providing protocol mediation.

B. The Mediation Layer facilitates communication between layers in the architecture and between the architecture and the systems that connect to the architecture.

C. The Mediation Layer provides the data translations needed to convert all Data Services data formats to the normalized data format.

D. Every call between layers in the architecture must pass through the Mediation Layer.

E. The Mediation Layer provides the bulk data movement capability for the architecture.

問題5

When the SOA roadmap process is described to a customer, the customer balks at the approach because the first step in the process is a current state analysis. From past experience the customer has seen current state assessments that took months to complete. The customer is not willing to spend months on another current state assessment. How is this customer issue addressed by the SOA roadmap development approach?

A. The current state assessment is done by reviewing documents provided by the customer. Two weeks is sufficient to review the documents and determine the current state.

B. The current state assessment is performed by evaluating the maturity and adoption of capabilities in the SOA Maturity Model. This narrow focus allows the assessment to be completed in approximately two weeks.

C. The scope of the current state assessment is restricted to the projects that the Project Selection Framework identified as the best SOA projects. This limited set of projects can be assessed in approximately two weeks.

D. The current state assessment is time boxed to two weeks. At the end of the two weeks, thecurrent state assessment is deemed complete and the next step in the roadmap creation process is begun.

E. The scope of the current state assessment is limited to one business unit at a time. This keeps the length of the assessment to approximately two weeks.

正確答案: B

問題6

Business users are asking for access to data that already exists in the enterprise but each back-end system is based on differing technologies making it challenging for the business users to access the data in a simple and expedited manner. How can the SOA conceptual architecture support this need?

A. Data is copied from the various source systems into an operational data store. This operational data store is then exposed to service consumers as common presentation services,

B. Existing data sources are exposed via the Service Bus.

C. Existing data sources are service enabled and exposed as common reusable Data Services.

D. Existing data sources are service enabled and exposed as common reusable Business Activity Services.

E. Existing data sources are service enabled and exposed as common reusable Business Activity Services, which in turn call the appropriate Data Services.

正確答案: A

問題7

During Service identification and discovery, which three reasons you would use a business function model?

A. To summarize what an enterprise does and the relationship between those functions

B. Define the organizational structure for the business

C. Provide a structure for a federated enterprise service bus deployment

D. To identify functional overlap and linkages in the SOA project selection process

E. Identify the high-level business processes in the organization

正確答案: A,B,C

問題8

Whether from new/changing business requirements or technical optimizations, your Services are bound to change and evolve over time. The lack of a Service versioning strategy will greatly impact the flexibility of your SOA initiative as it will severely hinder Service evolution. Which three principles should be part of a Service versioning strategy?

A. Concurrent versions of a Service must always be deployed on the same physical server.

B. Service providers must be able to release new versions into production without waiting for consumers to certify on them.

C. Service consumers should not require code modifications in order to access the latest compatibleService versions.

D. A new version of a Service must be developed using the same technology (for example, Java) thatthe original Service was developed in.

E. Consumers must be able to test and certify on new Service versions before switching to the newversion in production.

正確答案: A,D,E
