A common security consideration with service-oriented solutions is the need to apply security at the transport layer as opposed to the message layer. Select the correct answer.

• A.False
• B.True

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

• A.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.
• B.Services benefit from design standardization because this supports service-oriented computing goals, such as Increased Intrinsic Interoperability.
• C.Services benefit from being concurrently invoked by different service compositions because this decreases their performance requirements while increasing their availability.
• D.Services benefit from up-front analysis because this allows them to be modeled before they are developed and deployed.

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

• A.Desktop Application A
• B.Database A
• C.Service B
• D.Service A

The ability of one service to __________ another service forms the basis of service
__________.

• A.divert, diversification
• B.integrate, integration
• C.consume, composition
• D.register, registries

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 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
• B.encourages you to bridge disparity between vendor platforms by using modern transformation technologies for long-term flexibility
• C.encourages you to commit to one vendor platform and stick with that platform, which fosters long-term flexibility
• D.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
