Question 6 |
In a good software design, __________ coupling is desirable between modules.
Highest | |
Lowest | |
Internal | |
External |
Question 6 Explanation:
→ Cohesion is a measure of internal strength within a module, whereas coupling is a measure of inter dependency among the modules.
→ So in the context of modular software design there should be high cohesion and low coupling.
→ So in the context of modular software design there should be high cohesion and low coupling.
Question 7 |
In software project planning, work Breakdown structure must be __________ .
A graph | |
A tree | |
A Eulars graph | |
None of the above |
Question 7 Explanation:
Work Breakdown structure(WBS) must be tree. The tree structure will give overall view of a project. Normally we can divide two types of WBS
1. Functional WBS
2. Activity WBS
WBS tree structure:
1. Functional WBS
2. Activity WBS
WBS tree structure:
Question 8 |
The prototyping model of software development is:
a reasonable approach when requirements are well-defined | |
a useful approach when a customer cannot define requirements clearly. | |
the best approach to use for projects with large development teams. | |
a risky model that rarely produces a meaningful product. |
Question 8 Explanation:
→ The prototyping model of software development is a useful approach when a customer cannot define requirements clearly.
Advantage:
1. We can develop the software where requirements are unclear
2. Customer satisfaction
Disadvantage:
1. Who pay cost of prototype
2. Required the design expertise

Question 9 |
A software design pattern used to enhance the functionality of an object at run-time is:
Adapter | |
Decorator | |
Delegation | |
Proxy |
Question 9 Explanation:
→ Software design pattern used to enhance the functionality of an object at run-time is Decorator.
→ Decorator will attach additional responsibilities to an object dynamically keeping the same interface.
→ Decorators provide a flexible alternative to subclassing for extending functionality.
→ Decorator will attach additional responsibilities to an object dynamically keeping the same interface.
→ Decorators provide a flexible alternative to subclassing for extending functionality.

Question 11 |
‘Abstraction’ is ____________ step of Attribute in a software design.
First | |
Final | |
Last | |
Middle |
Question 11 Explanation:
‘Abstraction’ is first step of Attribute in a software design. The process of removing physical, spatial, or temporal details or attributes in the study of objects or systems in order to more
closely attend to other details of interest.
