質問 2：
Service composition is the creating of a new SOA Service by aggregating existing SOA Services. Which statements are correct concerning the use of service composition within the Service-Oriented Integration architecture?
A. Service composition is allowed, but is discouraged because service composition leads to complex dependencies.
B. Service composition is allowed, even encouraged, by the SOI architecture.
C. Service composition should be avoided because service aggregation is provided by the Mediation Layer.
D. Service composition within the SOI architecture is allowed only when the aggregation is over SOA Services from lower layers in the architecture.
E. The SOI architecture is a layered architecture; therefore service composition is not allowed.

質問 8：
Select the most appropriate reason why three-tier architecture is a better architectural choice than simple client-server architecture for complex enterprise applications.
A. Three-tier architecture moves all processing to the client, thereby reducing the load on the server.
B. Three-tier architecture combines presentation, business logic, and data processing into a single layer to eliminate network latencies.
C. Three-tier architecture uses three threads to run the applications, so performance is better.
D. Three-tier architecture combines presentation, business logic, and data processing of business logic, data, and presentation. This allows the tiers to be independently scaled to maximize the investment.
