• Question 1:

  Which of the following SOA myths are false? SELECT ALL THAT APPLY

  A. "An application is considered service-oriented if it uses Web services."

  B. "It is required that you stick with a single SOA vendor platform in order to successfully achieve the strategic goals of service-oriented computing."

  C. "SOA projects always require enterprise-wide standardization and enterprise-wide global data models."

  D. "The successful adoption of SOA will help an organization become more agile and responsive."

  Correct Answer: ABC

• Question 2:

  Which of the following statements are false? SELECT ALL THAT APPLY

  A. Services benefit from up-front analysis because this allows them to be modeled before they are developed and deployed.

  B. Services benefit from design standardization because this supports service-oriented computing goals, such as Increased Intrinsic Interoperability.

  C. Services benefit from a "contract first" approach because this allows the contract to be the first part of the service that is installed and further enables the contract to be subsequently changed without impact to service consumers.

  D. Services benefit from being concurrently invoked by different service compositions because this decreases their performance requirements while increasing their availability.

  Correct Answer: CD

• Question 3:

  Which of the following statements are true? SELECT ALL THAT APPLY

  B. A service inventory is comprised of a collection of services.
