IBM C2160-667 Online Questions & Answers

• Question 81:

  A bank has decided to rewrite their payment system from CICS/VSAM to SOA/J2EE/DB2 to easily adapt to a rapidly changing market, improve reporting capability and comply with a corporate edict to migrate off CICS/ VSAM. The payment process is large and complex and includes three major sub-processes (Validation, Sanctions, and Disbursement) as well as additional supporting processes (e.g. Advising, Printing, and Reporting.)

  What is the first step in the roadmap that should be suggested to the client?

  A. Model major sub-processes, wrap existing CICS/VSAM for use by these processes and deploy the resulting solution.
  B. Model supporting processes and associated relational data model, then deploy the resulting solution.
  C. Model major sub-processes and associated relational data model, migrate selected CICS/VSAM to the new model and deploy the resulting solution.
  D. Model supporting processes, wrap existing CICS/VSAM and deploy the resulting solution.
  B. Model supporting processes and associated relational data model, then deploy the resulting solution.

• Question 83:

  A manufacturing company has a large environment where they are using WebSphere Message Broker as their Enterprise Service Bus (ESB). For the services that are provided to partners, a standard Service Level Agreement (SLA) of four seconds has been defined for the service response time.

  A. End-user response time monitoring should be provided.
  B. Monitor the Message Broker for response time of the services.
  C. Application Response Measurement (ARM) based monitoring should be provided.

• Question 84:

  A retail company is faced with the challenge of quickly introducing new products involving components from multiple lines-of-business. How can adopting SOA help this company meet this challenge?

  A. By introducing an Enterprise Service Bus (ESB) to support services created from existing legacy application functions.
  B. By providing a single view of disparate data sources through the use of Information as a Service.
  C. By introducing a portal for access to components from multiple lines of business to provide integration at the glass.
  D. By identifying services in each Line of Business (LOB) that would support new product development and marketing business processes.
  D. By identifying services in each Line of Business (LOB) that would support new product development and marketing business processes.

• Question 85:

  A financial services company manages retirement accounts for its corporate clients. The company has developed Web services for account and portfolio management and has deployed an Enterprise Service Bus (ESB) to mediate access to the services from various internal applications. Recently, the company has been getting pressure from some of its clients to expose its account and portfolio Web services externally so that clients can consume and integrate these services within their own internal Web applications. The company wants to ensure that access to the services by its clients is secure and controlled so that accounts are not compromised and also wants to minimize impact to its current IT infrastructure. The company consults an SOA Designer for guidance on the solution design. Which approach should the SOA Designer suggest to handle this requirement?

  A. Allow clients access to the services via a portal that exposes only those services applicable to each client.
  B. Create a business process to route client requests to the appropriate services based on business rules.
  C. Allow service access to clients via an exposed ESB gateway that restricts access to authorized requestors only.
  D. Update the existing mediation logic in the ESB to handle the security requirements and allow external applications to access the services.
  C. Allow service access to clients via an exposed ESB gateway that restricts access to authorized requestors only.

• Question 86:

  Existing applications running on CICS are identified as having the functionality required to implement a service interface. The decision has been made to use WebSphere Message Broker to implement the aggregation and transformation logic necessary to fulfill the service contract using the CICS application's APIs. The developers intend to expose the service using the SOAP/HTTP Web services features of WebSphere Message Broker. What needs to be done first to expose this service implementation?

  A. Create a message flow to act as composition logic which implements the interface.
  B. Deploy the service to the service registry and alert the service consumer projects.
  C. Provide lookup rights to the service in the service registry for the authorized consumers.
  D. Generate the Web services client proxy for the portlet to use to connect with WebSphere Message Broker.
  A. Create a message flow to act as composition logic which implements the interface.

• Question 87:

  A company is using the IBM SOA Solution Stack to create a new composite application to keep up with the changing marketplace. Functions and data from several existing Enterprise Information Systems (EIS) will be aggregated into the new application using a top-down approach. See the information in the Exhibit.

  

  Which solution is the most appropriate for implementation?

  A. Exposing existing applications using multiple adapters
  B. Exposing existing systems to heterogeneous clients
  C. Exposing existing applications with service components
  D. Exposing existing systems with a Web services gateway
  C. Exposing existing applications with service components

• Question 88:

  A music production company wants to develop a new way of creating and producing music. Their intent is to make it possible for musicians and technicians to collaborate remotely on new compositions. They want to explore an SOA

  approach.

  Where should the SOA Designer begin?

  A. Analyze the production company's legacy systems to identify candidate services and then propose additional services to facilitate collaboration.
  B. Identify best of breed file sharing, workflow, and collaboration tools that are Web services ready, and propose a portal with user-profile customization.
  C. Convene a workshop with all the stakeholders to clarify their goals and objectives, then develop use cases and business process models to achieve them.
  D. Because intellectual property ownership is a critical issue in this business, examine available digital rights management systems to see if they will work in an SOA.
  C. Convene a workshop with all the stakeholders to clarify their goals and objectives, then develop use cases and business process models to achieve them.

• Question 89:

  The employees of a large insurance firm use several applications that reside in CICS. There is also an existing application server and an in-house developed customer management system. Each application provides its own interaction

  services using different protocols and UIs.

  Which pattern is the most appropriate to create unified access to the existing applications?

  A. Expose application functionality as services and create a portal for access.
  B. Wrap application functionality as information services and present using Java Server Faces.
  C. Create an AJAX front end which uses REST calls to access the back end APIs.
  D. Use a Web services gateway to access the existing systems and integrate the information by creating a consistent Web 2.0-based user interface.
  A. Expose application functionality as services and create a portal for access.

• Question 90:

  A manufacturing company can receive many customer orders at once. When an order is received, the OrderProcessing business process allocates a unique order number, updates the Customer service and invokes the Credit service. The

  process does not continue until the Credit service notifies it that the customer's details are valid, and this can take some time.

  Since multiple instances of the OrderProcessing process can exist at runtime, how can a specific instance be selected when the Credit service is ready to send notification?

  A. By creating a time stamp that is correlated to the customer ID
  B. By creating a qualified identifier that includes the customer number
  C. By creating a correlation set that includes the order number and customer ID
  D. By implementing a parallel activity as part of the OrderProcessing flow
  C. By creating a correlation set that includes the order number and customer ID
