IBM C2160-667 Online Questions & Answers

• Question 61:

  Two existing applications share common data with each having their own database. Since the data is replicated between the two of them every night, it leads to problems during the day when either application works with potentially outdated

  data. The customer is considering SOA as a solution.

  Which SOA approach can most effectively solve this problem?

  A. Design a service interface on top of both applications allowing exchange of the shared data in real time.
  B. Create an information integration layer exposed as services, then re-factor both applications to use those services.
  C. Consolidate both databases into one and establish proper locking algorithms to ensure data integrity.
  D. Design a new service that encapsulates the shared data between the two applications.
  B. Create an information integration layer exposed as services, then re-factor both applications to use those services.

• Question 62:

  A company has been experiencing a substantially higher load on their online ordering system over the holidays. The assigned Solution Architect has recommended the use of selectors in routing the incoming requests based on market

  factors.

  Which important design consideration is being addressed when evaluating the business process aspect of an SOA solution?

  A. Evaluating a number of deployment options for load balancing
  B. Delivery of a consistent user experience under various load conditions
  C. Ability to respond quickly to high value orders
  D. Leveraging information services to improve customer satisfaction
  C. Ability to respond quickly to high value orders

• Question 63:

  An IT organization within a large global enterprise is convinced that adopting SOA would significantly improve their alignment to business requests for new functionality but they have questions regarding SOA governance. Which statement about SOA governance is true?

  A. SOA governance ties IT governance to enterprise governance by defining the roles andresponsibilities associated with processes that support the goals of the business.
  B. Management of the introduction of SOA must be incorporated into enterprise governance to be most effective.
  C. Business agility can best be achieved by introducing independent SOA governance at multiple levels within the enterprise organization together with executive sponsorship.
  D. The business organization must be educated about how SOA governance will solve their IT operational issues to ensure financial support from the various business units.
  B. Management of the introduction of SOA must be incorporated into enterprise governance to be most effective.

• Question 64:

  A retail bank built an SOA for their customer service portal. Their layered architecture contains services at all levels.

  The system is not providing the performance required.

  What should the SOA Designer examine first to identify the cause?

  A. Review network capacity since large numbers of small messages can introduce a high overhead ratio, limiting the data transmitted per message.
  B. Review the service governance processes making sure they are identifying duplication and ensuring service level requirements are being managed.
  C. Review database accesses since large numbers of service requests can result in contention for database connections, race conditions or unintentional locking.
  D. Review the granularity of the service operations to determine whether there are too many technical services relative to the number of business services.
  D. Review the granularity of the service operations to determine whether there are too many technical services relative to the number of business services.

• Question 65:

  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.
  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.

• Question 66:

  An SOA project consists of services deployed in a heterogeneous distributed environment that includes an Enterprise Service Bus (ESB). When adding a requirement for routing management, how should it be implemented?

  A. As additional mediation capabilities within the existing ESB
  B. As additional management capabilities within the existing ESB
  C. As specific mediation functions implemented as separate proxies
  D. As a specific management function implemented in a federated ESB
  A. As additional mediation capabilities within the existing ESB

• Question 67:

  During the planning phase of SOA governance, which task should be one of an SOA Designer's first priorities?

  A. Ensure the currently deployed services honor Service Level Agreements (SLAs).
  B. Assess tooling to enforce governance control points.
  C. Analyze processes affected by SOA adoption.
  D. Understand how to support identified KPI metrics in the governance model.
  C. Analyze processes affected by SOA adoption.

• Question 68:

  An Architect is developing the security architecture for an organization where there are currently two security registries - RACF for CICS applications and LDAP for Web applications. The CICS applications are currently being accessed internally via MQ with user credentials in the MQ header. As part of an SOA initiative, the legacy applications are being exposed to partners via Web services on WebSphere Application Server using JCA to access the CICS applications. At which point in the architecture is the credential mapping performed?

  A. In the WS-Security header provided by the service consumer
  B. In the credential token (LTPAtoken)
  C. In the adapter
  D. In a mediation in an Enterprise Service Bus (ESB)
  C. In the adapter

• Question 69:

  A customer wants to build an executive dashboard using information stored in a CICS application with data in legacy files, as well as customer profiles from a third party service. The IT department wants to build a data warehouse, but

  management is concerned about the expense and duration of this approach.

  Which is a viable, service-enabled alternative?

  A. Recommend the construction of a federated data solution to provide a single view of data in the various customer systems providing on demand data cleansing and aggregate into a portal dashboard.
  B. Re-face the CICS screens and scrape off the needed data, then aggregate into the required dashboard.
  C. Specify the dashboard and required information services, and then develop transformation components for the required information.
  D. Specify the executive view of the dashboard, elaborate the data model required to support the dashboard, specify the source-target mappings, and populate the data model.
  C. Specify the dashboard and required information services, and then develop transformation components for the required information.

• Question 70:

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