QUESTION: 95
Service A is invoked by Desktop Application A, which requests a data value from Service A. In order for Service A to retrieve this data value, it must invoke Service B, which retrieves the value from Database A. Which participant(s) in this scenario are considered service consumers? SELECT ALL THAT APPLY
1. Service A

Answer: A, B, C
QUESTION: 99
Which of the following statements are false? SELECT ALL THAT APPLY
1. Services benefit from up-front analysis because this allows them to be modeled before they are developed and deployed.
2. Services benefit from design standardization because this supports service-oriented computing goals, such as Increased Intrinsic Interoperability.
3. 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.
4. Services benefit from being concurrently invoked by different service compositions because this decreases their performance requirements while increasing their availability.
Answer: C, D
