Q1. One of the goals of your newly formed SOA Initiative is to address current integration brittleness and inflexibility. Which option best supports your goal?
A. Make sure the Service contract details how the Service was implemented so that the Service consumer can take advantage of the underlying technology platform.
B. Utilize XML because it is flexible and Service consumers can transform the Service payload easily.
C. Decouple Service consumers from Service providers by encapsulating and abstracting the source systems behind a Service interface
D. Utilize REST Services because they are more flexible because they are not restrained by WS* standards.
Answer: C
Explanation:
Service-oriented integration done correctly avoids thebrittleness of a point-to-pointintegration architecture. In service-oriented integration the consumer is decoupledfrom the source system via the SOA Service that encapsulates and abstracts the sourcesystems behind a service interface. Consumers of the SOA Service should need nodetails about the underlying source system. They should base the service usage solelyon the contract provided by the SOA Service.

Q2. Business functional modellingis useful for modelling organizations that wish to adopt SOA. Select the three statements below that describe the benefits of business functional modelling to SOA.
A. A business functional model assists in minimizing functional duplication.
B. A business functional model provides a holistic view of the enterprise to avoid leaving gaps in theanalysis.
C. A business functional model progresses from fine to coarse-grained analysis which helps identify high value services.
D. A business functional model is dependent on the organizational structure,
E. A business functional model progresses from coarse to fine-grained analysis which helps identifyunique services that can be turned into coarse-grained services through composition.
Answer: A,B,E
Q3. You are a developer working on a Service implementation and you notice that there may be an opportunity to make use of another external Service to deliver your implementation. What steps should you take to make use of that Service?
A. Incorporate the Service using its published interface and inform the governance board when the project is finished, so as not to delay the delivery schedule
B. Create a second instance of the Service for your purposes so as not to affect the capacity of the current Service
C. Gather the re-use justification and present it the SOA governance board and wait for s/gn-off of your new design
D. Bypass the published interface and call the implementation of the other Service directly so as to reduce the latency of calling this Service
E. Copy and paste the implementation code for the second Service to expand the implementation of your own Service, so reducing latency to a minimum and creating a composite Service
Answer: D
Q4. While defining the SOA Requirements Management process, you have identified the need for a SOA repository. Which three items would you store against your Service?
A. Source code
B. Usage Agreements
C. Capacity Metrics
D. Security Policies
E. Build scripts
Answer: B,C,D
Q5. The SOA infrastructure you are building requires dynamic Service binding for loose coupling and a standards based way of storing and accessing Service descriptions at run time. How will you Implement this with Oracle products?
A. Use Oracle Service Registry (OSR), which provides a robust UDDI registry for runtime metadata information including Service descriptions (WSDl), and policies (WS-Pollcy).
B. Use Oracle BPEL Process Manager to implement dynamic Service binding functionality and SOA Service catalog
C. Implement Service discovery and dynamic Service binding functionality using Oracle Business Process Management (OBPM) and Oracle Business Rules (OBR) products
D. This functionality is not available in any of the Oracle products out of the box.
Answer: A
Explanation:
Oracle Service Registry (OSR) provides a robust UDDI registry for runtime metadatainformation including service descriptions (WSDL), and policies (WS-Policy). It maybe used to support loose coupling through dynamic service binding if a Service Bus isnot present. Please note that the Service Bus would be a basic requirement as SOAmaturity increases. OSR is also ideal for providing discovery of services when accessto a repository is not permitted.
Q6. The company you are working with wants to integrate an environment control system into the facility security and monitoring system. The environment control system sends temperature andhumidity readings every half second. What is the best message exchange pattern to use for this integration and why?
A. The one-way message exchange pattern is the best pattern for this scenario because it requires the least network resources and if a message is lost, another message with more up-to-date information will be sent in less than a second.
B. The reliable one-way message exchange pattern is the best pattern for this scenario because it provides a status return code so that a lost message can be re-sent.
C. The request-response message exchange pattern is the best pattern for this scenario because the security and monitoring system needs to provide a response message to the environment control system.
D. The request optional-response message exchange pattern is the best pattern for this scenario because the security and monitoring system may want to provide a response message to the environment control system.
E. The buffer-and-send message exchange pattern is the best pattern for this scenario because the messages from the environment control systems are grouped together and sent less frequently in larger messages thus reducing network traffic.
Answer: A

Q7. A project manager has come to you as the SOA architect asking why his Service Candidate has to be justified before he can build it. What two reasons are you going to give that it is important that Services must be justified before they are implemented?
A. The Services must be implemented by a single team and the Justification process prevents otherteams from creating Services.
B. SOA Services incur greater costs over their full lifecycle than application components and therefore must justify the extra investment before they are built.
C. No control over Service creation can result in Service proliferation resulting in a complex and inconsistent SOA that is difficult to manage and maintain.
D. The release of the Service needs to be co-ordinated with other projects and therefore his project will not be delivering it because the timescales are incompatible.
Answer: C,D
Q8. Your organization has decided to invest in SOA as a key component of your overall enterprise technology strategy. Identify three core benefits your organization can expect,
A. More rapid and cost-effective response to changing business needs
B. More effective reuse of macro-level business functionality
C. Automatic governance adherence
D. Immediate and significant ROI
E. Simplification of integration between existing IT assets
F. Total elimination for the need forEAI
Answer: A,B,C
Q9. Which of the following statements describes how the layers in the service-oriented integration architecture interact?
A. Upper layers in the architecture use capabilities provided by any of the lower layers in the architecture.
B. A layer in the architecture uses capabilities provided by the adjacent layers, that Is, the layer-above and the layer below.
C. A layer in the architecture uses capabilities provided by the adjacent lower layer in the architecture.
D. A layer in the architecture uses capabilities provided by the adjacent upper layer in the architecture.
E. The layers in the architecture expose functionality to the User Interaction Systems, but do not interact.
Answer: A
Explanation:
Upper layersin the architecture leverage the capabilities provided by the lower layers. Generally,upper layers call lower layers in the architecture and the reverse (i.e. lower levelscalling upperlayers) is prohibited. There may be some special cases that are exceptionsto this rule. Upper layers are allowed to call capabilities provided byany lower layer and, therefore, may skip any intermediate layers.

Q10. Services, Service consumer applications, and SOA Infrastructure components are instrumented to report on various events and conditions within the SOA environment at run time. The types of information they log can vary widely depending on the types of events in an organization. What are two example of these events?
A. Business value of the Service
B. Performance and load characteristics
C. Service exceptions
D. Service reuse metrics
Answer: B,C
