• Question 26:

  Which of the following statements is true?

• Question 27:

  Service-oriented computing advocates establishing a technology architecture with increased vendor technology diversity, which means that service-oriented solutions need to be consistently built using different vendor technologies and products.

  This way, the failure of any one vendor technology or product will not bring down all services within a service inventory. Select the correct answer.

  A. True
  B. False
  B. False

• Question 28:

  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.
