Q31.
What is the primary purpose of validation in the software life cycle?

a.

To ensure internal consistency and completeness within the design.

b.

To demonstrate that the customer's requirements are satisfied.

c.

To automate the coding activity from detailed design.

d.

To capture the non-functional requirements of the system.

Discuss
Answer: (b).To demonstrate that the customer's requirements are satisfied. Explanation:The primary purpose of validation in the software life cycle is to demonstrate that the customer's requirements are satisfied. It involves checking if the design meets the expectations and needs of the customer.
Q32.
Which phase of the software life cycle involves correcting errors in the system after release and revising the system to satisfy new requirements?

a.

Requirements specification

b.

Coding and unit testing

c.

Integration and testing

d.

Maintenance

Discuss
Answer: (d).Maintenance Explanation:The phase of the software life cycle that involves correcting errors in the system after release and revising the system to satisfy new requirements is Maintenance. It is an ongoing activity that continues after the product's release.
Q33.
What is the main difference between a formal proof and a rigorous proof?

a.

A formal proof relies on the understanding of the reader to accept its correctness, while a rigorous proof is entirely justified by the rules of the mathematical language.

b.

A formal proof is represented within a mathematical language, while a rigorous proof occurs within a natural language.

c.

A formal proof contains full details of the argument, while a rigorous proof leaves out some details while still maintaining acceptance.

d.

A formal proof is commonly used for verification, while a rigorous proof is used for validation.

Discuss
Answer: (c).A formal proof contains full details of the argument, while a rigorous proof leaves out some details while still maintaining acceptance. Explanation:The main difference between a formal proof and a rigorous proof is that a formal proof contains full details of the argument, while a rigorous proof leaves out some details while still maintaining acceptance.
Q34.
What is the "formality gap" referred to in the context of validation proofs?

a.

The gap between formal and informal languages used in software development.

b.

The gap between mathematical proofs and customer requirements.

c.

The gap between verification and validation in the software life cycle.

d.

The gap between software engineering and software development.

Discuss
Answer: (b).The gap between mathematical proofs and customer requirements. Explanation:The "formality gap" refers to the gap between mathematical proofs (formal) and customer requirements (informal) in the context of validation proofs. It represents the inherent ambiguity of the real world and the challenges of transforming informal requirements into a formal and structured development process.
Q35.
What may dictate the extent of proofs carried out in a design project?

a.

The complexity of the software life cycle.

b.

The cost and time constraints of the design project.

c.

The number of components involved in the system.

d.

The availability of automated tools for proof.

Discuss
Answer: (b).The cost and time constraints of the design project. Explanation:The extent of proofs carried out in a design project may be dictated by the cost and time constraints of the project. Complex proofs that require extensive resources may not be feasible within limited project timelines, so decisions are made based on perceived economic implications.
Q36.
Which type of proof is more commonly used for verification in software development?

a.

Formal proofs

b.

Rigorous proofs

c.

Informal proofs

d.

Mathematical proofs

Discuss
Answer: (b).Rigorous proofs Explanation:Rigorous proofs are more commonly used for verification in software development. While formal proofs are entirely justified by the rules of the mathematical language, rigorous proofs maintain acceptance without providing full details of the argument. They are practical and less resource-intensive compared to formal proofs.
Q37.
What does the "formality gap" imply for the validation of interactive systems?

a.

The validation process will rely entirely on formal mathematical proofs.

b.

The validation process will be entirely subjective and lack objective proof.

c.

The validation process will require experts with design expertise.

d.

The validation process will focus on architectural design.

Discuss
Answer: (b).The validation process will be entirely subjective and lack objective proof. Explanation:The "formality gap" implies that the validation process for interactive systems will be subjective to some extent and may lack objective proof. As the origin of customer requirements lies in the inherent ambiguity of the real world, formal proofs are not feasible, and validation will involve subjective means.
Q38.
How can the confidence in subjective proof be increased during validation?

a.

By using automated tools for verification.

b.

By narrowing the formality gap with real-world experts.

c.

By focusing on architectural design and decomposition.

d.

By using formal mathematical notations in the design.

Discuss
Answer: (b).By narrowing the formality gap with real-world experts. Explanation:The confidence in subjective proof during validation can be increased by effective use of real-world experts. These experts may not have design expertise, but their knowledge from relevant domains can provide valuable insights and validation of the system's interactive properties.
Q39.
What is the importance of design notations in narrowing the formality gap for validation?

a.

Design notations help in automating the validation process.

b.

Design notations enable experts to understand architectural designs.

c.

Design notations make it easier for experts to interpret and validate claims.

d.

Design notations are necessary for formal mathematical proofs.

Discuss
Answer: (c).Design notations make it easier for experts to interpret and validate claims. Explanation:Design notations are important in narrowing the formality gap for validation because they make it easier for experts to interpret and validate claims. The design notations should be readily interpretable from the perspective of the experts' domain, such as cognitive or psychological, to effectively validate the interactive properties of the system.
Q40.
In the context of software development, why are managerial issues of design important?

a.

They influence the architectural design of the software.

b.

They help determine the marketability and training needs of the system.

c.

They are essential for the detailed design of the software.

d.

They dictate the choice of programming languages for coding.

Discuss
Answer: (b).They help determine the marketability and training needs of the system. Explanation:Managerial issues of design are important in software development because they help determine the marketability of the system, its training needs, and other practical considerations that go beyond the technical aspects of development.
