    3) A government agency wants to ensure the selected patterns and code standards set down by their SOA governance body are adhered to.Which type of tool will support this?

    • A. Code generation

    • B. Parsing

    • C. UML modeling

    • D. Data modeling

    Correct Answer
    A. A. Code generation
    Explanation
    Code generation tools are used to automatically generate code based on predefined patterns and code standards. These tools ensure that developers adhere to the set standards and guidelines established by the SOA governance body. By automating the code generation process, these tools help in maintaining consistency and reducing human error. They also save time and effort by eliminating the need for manual coding. Therefore, code generation tools are the most suitable type of tool to support the government agency's requirement of ensuring adherence to selected patterns and code standards.

    7) The SOA reference architecture identifies core services including Interaction, Process, Information, Partner, Access, and Infrastructure.What is one valid reason for excluding one or more of these services in an SOA?

    • A. The application is predominantly middleware in nature, eliminating the need for presentation services.

    • B. The consumer and the provider belong to different companies.

    • C. The business sponsor has set budget constraints on solution architecture and the architectural components to be included have to be prioritized.

    • D. The customer's internal politics make the specification too difficult.

    Correct Answer
    A. A. The application is predominantly middleware in nature, eliminating the need for presentation services.
    Explanation
    One valid reason for excluding one or more of these services in an SOA is that the application is predominantly middleware in nature, eliminating the need for presentation services. This means that the application primarily focuses on facilitating communication and integration between different systems or components, rather than directly interacting with end-users or providing user interfaces. In such cases, presentation services may not be required as the application's main purpose is to enable the exchange of data and functionality between different systems.

    1) A retail catalog companys printing and mailing expenses are growing much more rapidly than revenue. Each time they update their database, they ship more catalogs and customers call in with more corrections.Which evaluation and recommendation should the SOA Designer make?

    • A. Data quality is low. Master data management should be installed to cleanse and maintain data quality both from data sources and updates from the call center.

    • B. Third party mail lists are inconsistent. Use process modeling to identify when multiple records are created and how multiple catalogs get printed. Then use process simulation to optimize new processes.

    • C. Processes do not incorporate data cleansing. Create an information service that retrieves similar records and displays them in a portlet, so operators can see multiple records and work with the customer to eliminate them.

    • D. Data entry is a very common source of error and customers are often inconsistent as well. Operator generated updates should be re-implemented to the indirect exposure solution pattern to separate data entry from record update permitting a data cleansing step in the update processes.

    Correct Answer
    A. A. Data quality is low. Master data management should be installed to cleanse and maintain data quality both from data sources and updates from the call center.
    Explanation
    The correct answer is A because the given scenario suggests that the company is experiencing issues with data quality, which is causing the printing and mailing expenses to increase. Installing a master data management system would help to cleanse and maintain data quality from both data sources and updates from the call center. This would ensure that accurate and reliable data is used for printing catalogs, reducing the need for corrections and ultimately lowering expenses.

    4) A company has an existing message-based middleware solution that allows exchanging business information among several applications using a topic-based publish-subscribe integration pattern. As part of its SOA strategy, the company is now embarking on service-enabling the applications and wants to employ the publish-subscribe pattern using Web services technology.Which Web services specification best addresses this need?

    • A. WS-Federation

    • B. WS-Addressing

    • C. WS-Notification

    • D. WS-MetaDataExchange

    Correct Answer
    A. C. WS-Notification
  • 6. 

    5) Why is it necessary to enforce policies and monitor services within SOA Services Management?

    • A. To insure data integrity and correlate business processes

    • B. To trace transactions and diagnose problems

    • C. To collect key performance metrics

    • D. To ensure service availability

    Correct Answer
    A. D. To ensure service availability
    Explanation
    Enforcing policies and monitoring services within SOA Services Management is necessary to ensure service availability. By enforcing policies, organizations can set rules and regulations for the services to ensure they are functioning properly and are available for use. Monitoring services allows organizations to track the performance and availability of the services, identify any issues or problems, and take necessary actions to ensure uninterrupted service availability. This helps in maintaining a reliable and efficient service infrastructure for the users.

    2) A company wants to integrate a number of existing best-of-breed applications by implementing service facades and an Enterprise Service Bus (ESB). The initial scenario involves the transfer of order information between a number of these backend services depending on business rules. An SOA Designer is asked to capture the functional requirements.What is the most appropriate starting point?

    • A. Analysis of the information requirements of the existing applications

    • B. Investigation into appropriate industry standards for transferring data

    • C. Creation of use cases to understand what the services may be and how they interact

    • D. Define the component model associated with the existing applications and specify the service interfaces

    Correct Answer
    A. C. Creation of use cases to understand what the services may be and how they interact
    Explanation
    The most appropriate starting point in this scenario is the creation of use cases to understand what the services may be and how they interact. This is because use cases help in identifying the different functionalities and interactions required between the existing applications. By creating use cases, the SOA Designer can gain a clear understanding of the business requirements and define the scope of the services that need to be integrated. This will provide a solid foundation for designing the service facades and the Enterprise Service Bus (ESB) architecture.
