Explanation

Question 3 of 76

2

3.Which of the following statements is true?

Select one of the following:

  • A. "Contract first" design is important to SOA because it makes you think about service contract design
    options at the same time that you are building the underlying service logic.

  • B. "Contract first" design is important to SOA because it forces you to establish standardized service
    contracts prior to the development of the underlying service logic.

  • C. "Contract first" design is important to SOA because without a contract, services cannot be invoked.
    However, there is no preference as to when, during the service delivery lifecycle, the contract should be
    designed or established.

  • D. "Contract first" design is an unproven design technique that is not commonly employed when
    delivering service-oriented solutions and is therefore not considered important to SOA.

Explanation

Question 57 of 76

2

57.An IT enterprise proceeds with an SOA initiative that is based on the creation of a single enterprise
service inventory. However, conflicts arise when different IT departments disagree on who will own the
services and how they will be governed. Which of the following alternative approaches could be chosen to
address these conflicts?

Select one of the following:

  • A. The top-down approach is chosen. This allows services to be modeled subsequent to their design,
    thereby enabling each service to be governed by multiple owners.

  • B. It is decided to proceed with the creation of multiple domain service inventories. This allows collections of services to be independently governed by different owners, while still enabling the IT enterprise as a whole to transition toward SOA.

  • C. The established "contract last" approach is chosen, allowing different IT managers to focus on
    contract-related governance issues after the services are deployed and in use.

  • D. Because SOA projects absolutely require enterprise-wide standardization and further demand the
    creation of an enterprise service inventory, the IT managers have no choice than to cancel the project.

    reusable services. Over time, this will allow us to improve the cost-effectiveness of IT as a whole."

  • C. "SOA will help us streamline our IT enterprise. Our goal, ultimately, is to turn the IT department into a part of the organization that provides increased value to the business while reducing its overall burden."

  • D. "SOA will help our IT department overcome cultural challenges we've traditionally had with the
    ownership of EAI (Enterprise Application Integration) platforms. Through the use of proven bridging and transformation technologies introduced by SOA, any IT staff that have historically disagreed with each other about ownership issues, will now be able to overcome their differences."

Question 61 of 76

61.Below are excerpts from four different SOA adoption strategy documents. Based on your
understanding of SOA, service-orientation, and the goals of service-oriented computing, select the
adoption strategy that is clearly the most likely to succeed:

Select one of the following:

  • A. "As part of our planned transition toward service-orientation, we will continue to extend the existing legacy applications with transformation-centric middleware that will enable seamless integration and runtime conversion between the different data models and data formats used by these applications."

  • B. "Each of our existing legacy applications already establishes a domain boundary that is defined by the purpose of the application. We are confident that by leveraging these pre-defined silo-based boundaries we can create a series of effective domain service inventories, each with a scope that corresponds to a legacy application boundary."

  • C. "Our strategy fully supports the tactical (short-term) nature of service-oriented computing by
    de-emphasizing standardization and allowing different project teams to deliver services optimized to their respective requirements. This not only speeds the initial delivery of services, it further supports
    interoperability by enabling services to leverage established integration technologies."

  • D. "Our strategy is to make the consistent application of service-orientation principles a priority in order tosupport the attainment of the goals of service-oriented computing. The primary justification for this approach is the fact that we have identified the goals of service-oriented computing to be in alignment with our own business goals."

Question 62 of 76

62.Which of the following is an expected result of successfully adopting SOA?

Select one of the following:

  • A. A natural increase in runtime performance that you will gain as a result of the fact that service
    compositions will often be comprised of a greater amount of individually participating programs (services) than traditional distributed applications.

  • B. The fact that the existing IT organizational structure will not have to change because of how well a
    service-oriented enterprise fits into traditional IT departmental structures that are focused on
    project-centric application delivery.

  • C. The tactical (short-term) focus of service-orientation, which allows for the initial rapid delivery of
    services without concerns about their subsequent governance.

  • D. The strategic (long-term) target state that is attainable when many of the services delivered are
    interoperable and reusable, thereby allowing for them to be repeatedly composed in response to new and changing business requirements.

Explanation

Question 63 of 76

2

63.Service Composition A is comprised of 4 services. Service Composition B is comprised of 6 services.
Because both service compositions are comprised of services from the same service inventory, the
service inventory will have a total of how many services?

Select one of the following:

  • A. 10

  • B. 24

  • C. Based on the information provided, it's impossible to know how many services reside in the service
    inventory because we don't know how many other service compositions exist.

  • D. Based on the information provided, it's impossible to know how many services reside in the service
    inventory because the quantity of services within a service inventory is not determined by the quantity of services in service compositions.

Explanation

Question 64 of 76

2

64.I built a service-oriented solution a year ago comprised of 3 services. I've just been told that the
business process automated by the solution is going to be replaced by a new business process that
introduces some changes to how the business process logic needs to be automated. What should I do?

Select one of the following:

  • A. Replace the solution with a brand new service-oriented solution comprised of new services designed
    specifically to automate the new business process.

  • B. Identify the services within the solution that are no longer relevant to the new business process and
    permanently retire them so that no other service-oriented solution inadvertently uses them.

  • C. Assuming there is an established service inventory in place, attempt to locate any existing services that can provide the logic required to automate the new business process and then change how the services within the solution need to be composed, as required.

  • D. Due to the fact that service-oriented solutions are inherently unable to adapt to business process
    change, you should investigate for how long you can continue to use your current solution. Even if it does not exactly provide the functionality required by the new business process, it is still likely to automate a subset of the new business process logic, thereby providing you with an opportunity to continue to get some value from the solution before you are forced to retire it.

Explanation

Question 65 of 76

65.Which of the following statements makes sense?

Select one of the following:

  • A. I am going to register my new service in the service registry so that other project teams can discover it in order to determine whether they should reuse it as part of service-oriented solutions they are planning to build.

  • B. I am going to register my new service inventory in the service registry in order to improve the
    performance of my service-oriented solution, because other services in my service composition will be able to dynamically discover and retrieve the new service much faster than if it was not registered in the service registry.

  • C. I am going to register my new service in the service registry because Service Registration is one of the
    eight principles of service-orientation.

  • D. None of these statements make sense.

Select one of the following:

  • A. Service A, Service B, Service C

  • B. Service D, Service E

  • C. Service A

  • D. None, because a service cannot also be a service consumer.
