.Which of the following statements is true?

"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. ✘ "Contract first" design is important to SOA because it forces you to establish standardized servicecontracts prior to the development of the underlying service logic. ✘ "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. ✘ "Contract first" design is an unproven design technique that is not commonly employed when deliveringservice-oriented solutions and is therefore not considered important to SOA. ✔

.Below are four statements about business and technology alignment, as it pertains to service- orientedcomputing. Which of these statements is false?

Business and technology alignment represents the extent to which an IT enterprise and its automated
systems can mirror and evolve in alignment with the business. ✘ Service-oriented computing promotes the abstraction and accurate encapsulation and expression ofbusiness logic in services. This supports business and technology alignment. ✘ The pursuit of business and technology alignment can be supported by the collaboration of businessanalysts and technology experts during analysis and modeling phases. ✘ In order for an IT enterprise to increase business and technology alignment, its business analysts mustbecome more technical and assume the responsibilities of technology experts so that they can
independently design quality business services that take both business and technology considerations
into account. ✔
