B) Services are designed to increase the need for integration.
C) Services are the fundamental building blocks of service-oriented solutions.
D) A service composition is comprised of services.

Accepted Answer

Services are designed to reduce the need for integration by providing standardized interfaces and promoting reusability and interoperability.

Question 4

What is wrong with this statement: "We delivered two services last year. Even though each service was delivered by a separate project team in a different location and at a different time, I am confident that the services will be reasonably interoperable because each project team was asked to use the same design standards."
A) The statement is incorrect because services should never be delivered by different project teams.
B) The statement is incorrect because services rely on post-implementation integration effort in order to achieve interoperability, not design standards.
C) The statement is incorrect because SOA delivery projects require that services be created at exactly the same time in order to guarantee interoperability.
D) There is nothing wrong with this statement.

Accepted Answer

The statement is correct because using the same design standards helps to ensure that the services will be reasonably interoperable.

Accepted Answer

Business analysts do not need to become technology experts; rather, collaboration between business analysts and technology experts is essential for achieving business and technology alignment.

Question 9

Which of the following statements is true?
A) To apply service-orientation requires the use of Web services.
B) Web services are required in order to build service-oriented solutions.
C) When discussing SOA and service-oriented computing, the term "Web service" must always be synonymous with (have the same meaning as) the term "service".
D) None of these statements are true.

Accepted Answer

Service-orientation does not require the use of Web services, nor are Web services required to build service-oriented solutions. The term "Web service" is not synonymous with "service" in the context of SOA.

Question 10

Which of the following statements is false?
A) Industry standards are usually produced by standards organizations.
B) Industry standards are usually created by standards committees so that they do not favor any one vendor or organization.
C) The use of industry standards alone automatically results in fully standardized service-oriented solutions.
D) XML is an example of an industry standard.

Accepted Answer

The use of industry standards alone does not automatically result in fully standardized service-oriented solutions, as implementation and integration specifics can vary.

Question 11

When designing service-oriented architectures, it is important to take the strategic goal of Increased Vendor Diversity Options into account, because this goal:
A) encourages you to commit to one vendor platform and stick with that platform, which fosters long-term flexibility
B) encourages you to retain the constant option of using proprietary vendor features and extensions so that they can be entrenched into your service-oriented architectures for long-term flexibility
C) encourages you to retain the constant option to extend or replace parts of your service-oriented architectures with different vendor technologies or products, which fosters long-term flexibility
D) encourages you to bridge disparity between vendor platforms by using modern transformation technologies for long-term flexibility

Accepted Answer

Increased Vendor Diversity Options aims to maintain the ability to switch or integrate different vendor technologies, enhancing flexibility and reducing dependency on a single vendor.

Question 12

Two common, yet opposing SOA delivery approaches are:
A) bottom-up and upside-down
B) top-down and left-to-right
C) upside-down and left-to-right
D) none of the above

Accepted Answer

The two common, yet opposing SOA delivery approaches are bottom-up and top-down, which are not listed as options.

Question 13

Solution logic is classified as "service-oriented" after:
A) it has been built using Web services
B) it has been built using RPC technologies
C) it has been performance tested to a meaningful extent

Accepted Answer

A service can be part of a service composition, which can be assembled from services within a service inventory.

Question 15

Which of the following statements does not make sense?
A) Intrinsic interoperability is important because it helps increase the quantity of integration projects that may be required to accommodate new business requirements, thereby fostering agility.
B) Intrinsic interoperability is important because it enables services to exchange data without having to resort to transformation technologies.
C) Intrinsic interoperability is important because it is fundamental to enabling services to be repeatedly composed.
D) Intrinsic interoperability is important because one of the goals of service-oriented computing is to increase intrinsic interoperability.

Accepted Answer

Intrinsic interoperability is important because it reduces the need for integration projects, not increases them, thereby fostering agility.

Question 16

The standardization of services within a service inventory supports the repeated __________ of services, thereby increasing their potential reuse.
A) integration
B) composition
C) definition
D) expression

Accepted Answer

Standardization of services within a service inventory supports the repeated composition of services, as it allows for consistent and predictable integration, making it easier to reuse services in different contexts.

Question 17

Which of the following is not a benefit of maintaining a vendor-neutral and business-driven context for a service-oriented architecture?
A) Establish a technology architecture with a fixed scope and purpose that remains unchanged, regardless of how the business may need to change over time.
B) Avoid establishing a technology architecture that will need to be replaced in the near future when it no longer adequately fulfills business requirements.
C) Leverage new technological innovation in order to maximize the fulfillment of business requirements.
D) Establish a technology architecture that can stay in alignment with how the business may need to change over time.

Accepted Answer

Maintaining a vendor-neutral and business-driven context allows for flexibility and adaptability, which is contrary to having a fixed scope and purpose that does not change with business needs.

Question 18

Which of the following statements is true?
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.

Accepted Answer

"Contract first" design is important to SOA because it ensures that standardized service contracts are established before the development of the underlying service logic, promoting consistency and interoperability.

Question 19

In order to achieve __________ we have traditionally required __________ projects. With service-orientation, we aim to establish an intrinsic level of __________ within each service so as to reduce the need for __________ effort.
A) vendor diversity, integration, vendor diversity, design
B) agility, development, scalability, development
C) interoperability, integration, interoperability, integration
D) autonomy, integration, statelessness, integration
