4. Which of the following are correct statements?
a) An architecture may or may not defines components
b) An architecture is not dependable on requirements
c) An architecture is foremost an abstraction of a system that suppresses details of the components that do not affect how they are used
d) All of the mentioned

5. What does “Every software system has an architecture” implies?
a) System itself is a component
b) Architecture an exist independently of its description or specification
c) All the system to be stable should posses an architecture
d) None of the mentioned
Answer: c
Clarification: All the system to be stable should posses an architecture, a system without architecture is unstable hence every software system has an architecture.

c) It is set of constraints on architecture
d) All of the mentioned
Answer: d
Clarification: An architectural style is a description of component types and pattern of run-time control, It is set of constraints on architecture.
7. What is a Reference Model?
a) It is a division of functionality together with data flow between the pieces
b) It is a description of component types
c) It is standard decomposition of a known problem into parts that cooperatively solve a problem
d) It is a division of functionality together with data flow between the pieces, It is standard decomposition of a known problem into parts that cooperatively solve a problem
Answer: d
Clarification: A reference model is division of functionality together with data flow between the pieces and standard decomposition of a known problem into parts that cooperatively solve a problem.
8. What is Reference architecture?
a) It is a reference model mapped onto software components
b) It provided data flow with comments
c) It provides data flow with pieces
d) It is a reference model mapped onto software components & data flow with comments
Answer: d
Clarification: Reference architecture is a reference model mapped onto software components and data flow with components.
