Question No: 41

While monitoring the effectiveness of your existing SOA governance model you notice that employees are not acting, interacting, and collaborating in the best Interest of your SOA initiative. What best approach should you take to address your challenges?

  1. Hold meetings for interested employees where they are encouraged to read and understand the standards and policies to which they must adhere

  2. Project teams are given ultimatums to adhere to standards and policies or pay the consequences

  3. Have visible and vocal support from a sponsor who re-iterates the importance of the SOA initiative and the role that employees will play

  4. Project teams are given both ultimatums and inducements to adhere to standards and policies

  5. Define a SOA Center of Excellence that hires external consultants to develop Services that adhere to standards and policies

  6. Give inducements to project teams to adhere to standards and policies

Answer: D

Question No: 42

Which statement describes how complexity, effort, and benefit are used In the SOA Project Selection Framework?

  1. Complexity measures the number of integrations that the projectwould require. Effort measures the amount of effort that existing shared services would save for the project.

    Benefitmeasures the amount of additional revenue that would result from the project, A top project for inclusion would have a larger benefit and effort with a lower complexity.

  2. Complexity measures the number of integrations that the project would require. Effort measures the amount of effort that existing shared services would save for the project. Benefit measures the business benefit that would be delivered by the project. A top project for inclusion would have a larger benefit and effort with a lower complexity.

  3. Complexity measures the technical complexity of the project. Effort measures the level of effort required to complete the project. Benefit measures the amount that the project would advance the SOA maturity of the organization. A top project for inclusion would have a larger benefit than the effort.

  4. Complexity measures the technical complexity of the project. Effort measures the level of effort required to complete the project. Benefit measures the amount of business benefit that would be delivered by the project. A top project for inclusion would have a large benefit and lower complexity and effort.

  5. Complexity measures the technical complexity of the project. Effort measures the level of effort required to complete the project. Benefit measures the amount of business benefit that would be delivered by the project. A top project for inclusion would have a large benefit and an effort that is lower than the complexity.

Answer: B

Question No: 43

Which statement completes the following sentence about SOA requirements? SOA requirements differ from traditional project requirements because SOA requirements…

  1. Are realized by shared Services which are not owned by any single application, consist of their own lifecycle, and are managed independently.

  2. May be implemented by existing applications, applications that are being developed, or proposed applications that have not yet been delivered.

  3. Once handed to a project by the business, can be purely managed by that project.

  4. Are focused on defining the integration points between applications,

  5. Should only be managed by a SOA centre of excellence.

Answer: A Explanation:

In order to achieve effective SOA, applications simply cannot be developedindependently of one another. Further, SOA applications utilize shared Services whichare not owned by any single application, consist of their own lifecycle and aremanaged independently. In order to be effective in managing requirements within anSOA, applications have to be aware of the requirements of existing applications,in-flight applications, as well as proposed applications.

Question No: 44

Which role is critical in promoting the discovery and reuse of SOA Services and supporting the service lifecycle?

  1. Service Development Platform

  2. Service Bus

  3. Metadata Repository

  4. Service Registry

Answer: B

Question No: 45

While using the Service Candidate Selection Framework It becomes apparent that there is another factor specific to the organization that negatively impacts the development of Services that is not being captured by any of the existing criteria. How should this situation be handled?

  1. A new realization inhibitor criterion should be added to the Parameters worksheet (and be propagated through the other worksheets) to capture and score this additional factor.

  2. A new realization benefit criterion should be added to the Parameters worksheet (and be propagated through the other worksheets) to capture and score this additional factor.

  3. New realization benefit and realization inhibitor criteria should be added to the Parametersworksheet (and be propagated through the other worksheets) to capture and score this additional factor.

  4. This additional factor should be ignored because all of the important criteria are already included in the Service Candidate Selection Framework.

  5. Replace one of the existing realization Inhibitor criterion with a new criterion that captures this additional factor.

  6. Replace one of the existing realization benefit criterion with a new criterion that captures this additional factor.

Answer: B,F

Question No: 46

Question No: 47

OASIS s SOA-RM defines high-level terms intended to provide commonality when discussing and describing SOA. Which two statements are true when comparing SOA-RM with Oracle#39;s Service meta-model?

  1. Both SOA-RM and Oracle#39;s Service meta-model separates the textual aspects from the technicalaspects.

  2. SOA-RM and Oracle#39;s Service meta-model differ on the specifics of the constituent parts of a Service.

  3. Oracle#39;s Service meta-model breaks out the service interface as a first class facet of a Service;whereas the SOA-RM combines the service interface in with the service description.

  4. SOA-RM addresses Usage Agreements as defined by Oracle.

  5. SOA-RM execution context maps directly with Oracle#39;s definition of a Service Implementation.

Answer: A,C Explanation:

The SOA RM definition of a Service is similar to the one provided by ORA. There isno glaring discrepancy between the two concerning the definition of a Service.However, the two differ on the specifics of the constituent parts of a Service. The SOARM describes three constituent parts of a Service just like ORA does. ORA breaks outthe Service Interface as a first class facet of a Service; whereas the SOA RM lumps theservice interface in with the service description.

ORA separate the human-readable, textual aspects ofthe Service from the technicalaspects. The textual aspects are the Usage Agreement and the Service Contract. Thetechnical aspects are the Service Interface and the Service Implementation. The SOARM does not separate them. Both the service description and the contracts andpolicies include both technical and textual contents.

Question No: 48

How should the stated service-oriented Integration architecture principles be applied at an organization?

  1. All of the architecture principles must be followed. If any of the principles are violated, the architecture is not service oriented.

  2. The organization should review and evaluate the architecture principles, and then derive their own architecture principles that match their specific environment and goals.

  3. An organization can add additional architecture principles, but the stated architecture principles must be followed.

  4. An organization can decide to not enforce one or more of the architecture principles, but additional architecture principles will not be needed.

  5. The architecture principles define what products will be used in the architecture, so the architecture principles must be adjusted to reflect the chosen products.

Answer: B

Question No: 49

Whether from new/changing business requirements or technical optimizations, your Services are bound to change and evolve over time. The lack of a Service versioning strategy will greatly impact the flexibility of your SOA initiative as it will severely hinder Service evolution. Which three principles should be part of a Service versioning strategy?

  1. Service providers must be able to release new versions into production without waiting for consumers to certify on them.

  2. A new version of a Service must be developed using the same technology (for example, Java) thatthe original Service was developed in.

  3. Concurrent versions of a Service must always be deployed on the same physical server.

  4. Service consumers should not require code modifications in order to access the latest compatibleService versions.

  5. Consumers must be able to test and certify on new Service versions before switching to the newversion in production.

Answer: B,C,E

Question No: 50

What two aspects of an existing requirementsmanagement approach need to be extended when adopting SOA?

  1. Requirements need to be assessed against the enterprise business model and not just the immediate project’s scope.

  2. Need to encompass requirements from operational staff to manage deployed Services as well as the business

  3. Requirements need to expressed in terms of a Service contract, implementation, and interface.

  4. All requirements are captured regardless of whether Services will be built from them.
