IBM C2160-667 Online Questions & Answers

• Question 51:

  A. Include clustered servers in the environment
  B. Include a workload manager in the environment
  C. Include a workload manager with a set of clustered servers in the environment
  D. Include an OSI layer three network load balancer with a set of clustered servers in the environment
  C. Include a workload manager with a set of clustered servers in the environment

• Question 52:

  An organization is adding composite services to the environment. The services are running across different environments and operating systems. When considering secure access, what is one of the additional challenges that must be considered?

  A. The requirement to use identity provisioning across the service request
  B. The requirement to use the same authorization privileges throughout the service request
  C. The requirement to use the same identity throughout the service request
  D. The requirement to use the same credentials throughout the service request
  C. The requirement to use the same identity throughout the service request

• Question 53:

  It has been determined that an application running on a mainframe needs to be service-enabled to allow it to be invoked asynchronously via an Enterprise Service Bus (ESB). The application interface is already capable of accepting

  WebSphere MQ messages, and the SOA designer does not wish to modify the current application code.

  What is an appropriate method of service-enabling the application that would also offer a high level of reuse of the resulting service in a business process?

  A. Use WebSphere Process Server to invoke an adaptor that manages WebSphere MQ over the MQ Link.
  B. Build a WebSphere ESB mediation to call an EJB which sends JMS messages via an MQ Queue Connection Factory.
  C. Create a service wrapper in WebSphere Message Broker which mediates between SOAP over JMS and the applications own data format delivered via MQ.
  D. Create an adapter connector using a WebSphere DataPower appliance that switches between HTTP at the front-end and MQ to communicate with the application at the backend.
  C. Create a service wrapper in WebSphere Message Broker which mediates between SOAP over JMS and the applications own data format delivered via MQ.

• Question 54:

  At an organization, some standards-based technologies have been adopted around a J2EE application server. There is now a need to provide multi-channel access to existing service providers. Which product should be used for service connectivity in this design?

  A. WebSphere Message Broker
  B. WebSphere Service Registry and Repository
  C. WebSphere Enterprise Service Bus (ESB)
  D. DataPower SOA Appliance
  C. WebSphere Enterprise Service Bus (ESB)

• Question 55:

  A hospital had fully federated its patient databases when patient privacy laws were passed. The CIO expects more regulation in the future. Which high level design pattern should the SOA Designer use to best address this nonfunctional requirement?

  A. Direct Exposure
  B. Indirect Exposure
  C. Web Service Proxy
  D. Requester Side Caching
  B. Indirect Exposure

• Question 56:

  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
  A. Code generation

• Question 57:

  An organization in the utilities sector has used WebSphere MQ for several years. Over time, the staff has developed expertise in WebSphere MQ and they are most comfortable solving problems using messaging- based technology. They

  plan to take advantage of SOA but are concerned about the risk of moving to new technology.

  Which technical solution should be suggested for this client?

  A. Create service faades for existing applications using WebSphere Message Broker.
  B. Use SOAP messaging with WebSphere MQ applications and WebSphere Enterprise Service Bus (ESB).
  C. Use WebSphere MQ pub/sub messaging to decouple service consumers from service providers.
  D. Use WebSphere MQ services instead of an ESB.
  A. Create service faades for existing applications using WebSphere Message Broker.

• Question 58:

  A group of SOA Architects is discussing strategies to improve re-use without impacting the existing project deadlines. Which action is most likely to achieve the stated objective?

  A. Modify existing applications to use service interfaces that most closely correspond to existing APIs.
  B. Integrate existing applications based upon a canonical message model derived from industry- relevant specifications.
  C. Integrate existing applications using adapters that expose existing functionality as services.
  D. Use a mixed strategy of modifying existing applications and adaptation to service descriptions that are aligned with business goals.
  C. Integrate existing applications using adapters that expose existing functionality as services.

• Question 59:

  An SOA project implementation is underway in a large government organization. The development, testing, staging, and production environments have been installed and configured. Each environment consists of an Enterprise Service Bus

  (ESB), a registry and repository, a Web server, application servers, and Business Process Engine (BPEL).

  With only weeks before the project goes live with a business critical application, what should be recommended?

  A. Functional, performance and security tests are undertaken on the infrastructure and services as soon as possible.
  B. The capacity plan should be checked to ensure the systems are specified to cope with the predicted average and peak loads.
  C. Software Configuration Management (SCM) processes such as promotion of code through the various environments be tested to ensure policies defined in the governance model are enforced.
  D. Communication between the various environments and between the various system components is thoroughly tested.
  A. Functional, performance and security tests are undertaken on the infrastructure and services as soon as possible.

• Question 60:

  A retail online commerce company uses SOA to create internal applications for its call centers, partners, and customers. As they matured, they began to look at establishing SOA governance and enlisted the services of an SOA Designer.

  After an audit of the current environment, it was found that they were achieving very low reuse of services and data entities. Further investigation revealed that duplicate services and data entities were being created.

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

  A. A registry and repository should have been deployed to monitor and enforce service and data entity creation processes defined in the governance model. This should be done during the measure phase.
  B. A plan for migrating to a single version for each of the assets should have been created and a plan to deploy a registry and repository to enforce the asset creation processes. This should have been created in the planning phase.
  C. A single version of the duplicate services and data entities should have been created. A plan to migrate consumers to the new version should have been defined. A process for the governance of the creation of these assets should have been defined during the defining phase.
  D. A registry and repository should have been deployed to enforce service and data entity creation processes defined in the governance model. Staff should have been instructed on how to execute the new asset creation processes and on the importance of these procedures. This should all be done in the enable phase.
  C. A single version of the duplicate services and data entities should have been created. A plan to migrate consumers to the new version should have been defined. A process for the governance of the creation of these assets should have been defined during the defining phase.
