• A. Policy implementation
• B. QoS
• C. Security
• D. Verify invoice

Explanation: Policy implementation, quality of service, and security are cross-cutting utilities commonly supplied by the Application Service Layer.

• A. Strong coupling among objects
• B. Communications are prescriptive rather than being descriptive
• C. Data is separated from a service or behavior
• D. Data and methods are integrated into a single object

Explanation: SOA separates data from the service or behavior that operates on it, whereas object-oriented design commonly combines state and methods…

Explanation: A black-box view describes what a system does through its externally visible behavior without revealing its internal implementation.

• A. Yellow box
• B. Clear box
• C. White box

Explanation: In Cleanroom box-structure specification, the black box describes externally visible behavior, the state box encapsulates state and…

• A. State box
• B. Clean box
• C. White box
• D. Black box
