3. Which lines depict that architecture defines constraints on an implementation?
a) An implementation exhibits an architecture if it conforms to the structural decisions described by the architecture
b) The implementation need not be divided into prescribed components
c) An implementation exhibits an architecture if it conforms to the structural decisions described by the architecture and the implementation must be divided into prescribed components
d) None of the mentioned
Answer: c
Clarification: An implementation exhibits an architecture if it conforms to the structural decisions described by the architecture, the implementation must be divided into prescribed components.
4. Why does architecture dictates organizational structure?
a) Architecture describes the structure of the system being developed which becomes engraved in the development project structure
b) An implementation exhibits an architecture if it conforms to the structural decisions described by the architecture
c) Architecture may not describe structure as whole
d) None of the mentioned
Answer: a
Clarification: Architecture describes the structure of the system being developed which becomes engraved in the development project structure.
5. Which of the following is right dependence relationship?
a) Performance depends on how strongly components are coupled with other components in system
b) Re-usability depends on the volume and complexity of the inter-component communication and coordination
c) Modifiability depends on system’s modularization
d) All of the mentioned
Answer: c
Clarification: Performance depends on the volume and complexity of the inter-component communication and coordination, re-usability depends on how strongly components are coupled with other components in system and modifiability depends on system’s modularization.
6. Which of the following is correct for decisions made at life cycle level?

d) None of the mentioned
Answer: a
Clarification: Decisions at all level of like cycle from high level design to coding, implementation affect system quality.
