Exam 1: Fundamental SOA & Service-Oriented Computing (S90-01A)

Service-oriented architecture must be designed to be both integration-centric and silo-based.

Which of the following is not a benefit of maintaining a vendor-neutral and business-driven context for a service-oriented architecture?

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

Which of the following is an expected result of successfully adopting SOA?

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.

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

Two common, yet opposing SOA delivery approaches are:

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 common performance consideration when designing agnostic services is the fact that they contain generic processing logic which can decrease performance overhead, thereby reducing performance requirements.  Select the correct answer.

You can create __________ or __________ service inventories.

One of the fundamental characteristics of service-oriented architecture is:

"A primary focus of service modeling is the encapsulation and abstraction of business logic in support of defining business service candidates." What is wrong with this statement?

Agnostic solution logic is logic that is considered single-purpose because it is unique to one task.  Select the correct answer.

When designing service-oriented architectures, it is important to take the strategic goal of Increased Vendor Diversity Options into account, because this goal:

Service metadata can be centrally registered within a __________ for discoverability purposes.

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

By applying a __________ strategic scope to the technology architecture, it can be kept in constant synch with how the business evolves over time.

The distinct ownership and governance requirements introduced by agnostic services can introduce the need for more __________ staff and less __________ staff.

When following the distinct lifecycle phases of an SOA delivery project you are:

Service A invokes ServiceB. Service B invokes ServiceC. Service C invokes both Service D and Service E. In this runtime scenario, which services are acting as service consumers?
