• Question 41:

  What should be the initial approach for this scenario?

  A. Analyze the business process to uncover a new business model, then create service wrappers for legacy systems.
  B. Create service wrappers for legacy systems, then aggregate existing data and enable human interaction.
  C. Create service wrappers for the legacy systems, then reuse them in different processes.
  D. Analyze the existing information sources to deliver them as a service, then reuse the services in different processes.
  B. Create service wrappers for legacy systems, then aggregate existing data and enable human interaction.

• Question 43:

  A team is evaluating the maturity of a customer's solution architecture relative to the IBM SOA Foundation. It is discovered that the customer has invested heavily in an internally-developed Enterprise Service Bus (ESB) and that their ESB has

  functionality expected to be found in other SOA Foundation services, especially Process Services, Business Services, and Information Services.

  Which recommendation should be made?

  A. Continue development of the ESB because the architecture is generally compliant with the SOA Foundation.
  B. Stop development of the ESB because the architecture violates the principle of loose coupling among services.
  C. Continue using the ESB but begin a transition to a vendor-supported, standards-compliant ESB.
  D. Modify development priorities to shift Process Services functionality to other parts of the Solution Architecture.
  C. Continue using the ESB but begin a transition to a vendor-supported, standards-compliant ESB.

• Question 44:

  A new business process is being written that will call a number of new or existing Web services. As part of the SOA quality management process, which activity is the most appropriate?

  A. Test and validate that the Web services meet the Service Level Agreements (SLAs).
  B. Monitor and manage the service implementation platform.
  C. Monitor and manage the service availability.
  D. Provide an automated test platform for functional and regression testing.
  D. Provide an automated test platform for functional and regression testing.

• Question 45:

  A large government organization has been making significant and well publicized mistakes resulting in citizen dissatisfaction. The root cause is analyzed and found to be inconsistency in business processes and inconsistency of data from system to system. Several systems access and store data in inconsistent ways. Which parts of the IBM platform could provide the basis for the solution to these specific issues?

  A. DB2WebSphere Portal ServerWebSphere Business Services Fabric
  B. DB2WebSphere Business MonitorWebSphere Integration Developer
  C. Information ServerWebSphere Business ModelerWebSphere Process Server
  D. Information ServerWebSphere Business Modeler WebSphere Message Broker
  C. Information ServerWebSphere Business ModelerWebSphere Process Server

• Question 46:

  A large bank has a paper-based process for transferring funds between regional centers that takes days to complete. They want to use SOA to automate this process. As an SOA Designer, what is a likely reason to also include Partner Services?

  A. The automated process needs to provide self service and status tracking of the process to its users.
  B. The funds transfer process involves service calls to an internal workflow that controls the final step.
  C. There is a requirement to use Extract/Transform/Load (ETL) to move information from one service to another.
  D. There is a business requirement to conform to interchange standards like Society for Worldwide Interbank Financial Telecommunication (SWIFT).
  D. There is a business requirement to conform to interchange standards like Society for Worldwide Interbank Financial Telecommunication (SWIFT).

• Question 47:

  A mobile phone company uses SOA to create internal applications for its call centers, partners, and customers. The organization is beginning to establish SOA governance and has enlisted the services of an SOA Solution Designer. As part of

  an audit of their current environment, it is found that they are achieving very low reuse of services and data entities. Further investigation reveals that duplicate services and data entities have been created.

  In which phase of the SOA Governance and Management Method should this problem be initially addressed and which action should be taken?

  A. In the monitoring phase, a registry and repository should be deployed to monitor and enforce service and data entity creation processes defined in the governance model.
  B. In the enabling phase, a registry and repository should be deployed to enforce service and data entity creation processes defined in the governance model. Staff should be instructed on how to execute the new asset creation processes and on the importance of these procedures.
  C. In the defining phase, a single version of the duplicate services and data entities should be created and a plan to migrate consumers to the new version should be defined. A process for the governance of the creation of these assets should be defined also.
  D. In the planning phase, a plan for migrating to a single version for each of the assets should be created. Additionally, a plan to deploy a registry and repository to enforce the asset creation processes should be created.
  C. In the defining phase, a single version of the duplicate services and data entities should be created and a plan to migrate consumers to the new version should be defined. A process for the governance of the creation of these assets should be defined also.

• Question 48:

  A large machine manufacturing company is using WebSphere Message Broker as an Enterprise Service Bus (ESB) providing routing and transformation functions. Manufacturing data is available from MQ enabled CICS transactions.

  Customer information is available via existing Web services on WebSphere Process Server (WPS) accessing UDB via JDBC. They are developing a new service to track the status of a customer's specific machine through production. The

  SOA Designer has decided to first create a Manufacturing Information service on WPS using JMS to access the CICS transactions.

  What is the rationale for this approach?

  A. Reusability
  B. Reliability
  C. Portability
  D. Data Consistency
  A. Reusability

• Question 49:

  In an environment with a federated Enterprise Service Bus (ESB) made up of a WebSphere DataPower Appliance and a WebSphere ESB, a new legal requirement is passed that requires logging of all messages that arrive from a particular

  set of external partners.

  How should this new compliance requirement be satisfied?

  A. Logging of the messages should be added to the compliance manager and enforced with the management product.
  B. Management proxy should be inserted for each of the services that are called by the external partners.
  C. Logging should be added to the WebSphere DataPower Appliance.
  D. Logging should be added to the WebSphere ESB.
  C. Logging should be added to the WebSphere DataPower Appliance.

• Question 50:

  The SOA Designer for a large corporation has been assigned the responsibility of defining the services for the purchasing area. The SOA Designer identifies the business needs and background information from the relevant stakeholder use

  cases. It is important that 95% of purchasing requests are processed within four hours.

  Which approach should be followed by the SOA Designer?

  A. Evaluate legacy application systems for relevant functionality and performance.
  B. Model the purchasing business process and simulate operations to correctly identify service granularity.
  C. Use goal service modeling to understand which candidate services are critical.
  D. Interview the stakeholders to find out which business services they would like to expose to business partners.
  C. Use goal service modeling to understand which candidate services are critical.
