Q201.
What is the purpose of Verification and Validation (V&V) in the waterfall model?

a.

To ensure that the system meets its requirements and is built correctly

b.

To prevent the system from diverging from the user's requirements

c.

To measure the progress of the project

d.

To assess the quality of the system

Discuss
Answer: (a).To ensure that the system meets its requirements and is built correctly Explanation:In the waterfall model, Verification (V) asks if the system meets its requirements and tries to assess the correctness of the transition to the next phase. Validation (V) asks if the system meets the user’s requirements. This is done in each phase of the software development process to ensure that the system meets its requirements and is built correctly.
Q202.
What is the main goal of Agile software development?

a.

To deliver the functionality as laid down in the contract

b.

To deliver value to the customer as quickly as possible

c.

To follow an extensive plan and process

d.

To achieve comprehensive documentation

Discuss
Answer: (b).To deliver value to the customer as quickly as possible Explanation:Agile methods focus on delivering value to the customer as quickly as possible and not bothering about extensive plans and processes that won't be followed anyway.
Q203.
What is the main difference between the traditional Waterfall model and the Agile methods?

a.

Waterfall model focuses on delivering value to the customer quickly and Agile methods focus on following an extensive plan and process

b.

Waterfall model is based on a strict sequencing of phases, while Agile methods are based on incremental and flexible development cycles

c.

Waterfall model is a document-driven approach, while Agile methods are a lightweight approach

d.

Waterfall model is a capital-intensive activity, while Agile methods are a labor-intensive activity

Discuss
Answer: (b).Waterfall model is based on a strict sequencing of phases, while Agile methods are based on incremental and flexible development cycles Explanation:The Waterfall model is a traditional model which emphasizes on a strict sequencing of phases and a careful analysis before the system is built. Agile methods, on the other hand, are based on a flexible development cycle, where change is a fact of life and the focus is on delivering value to the customer as quickly as possible.
Q204.
What is the primary focus of the waterfall model in software development?

a.

Delivering value to the customer as quickly as possible

b.

Careful analysis before the system is built

c.

Strict sequencing of phases

d.

Total life cycle cost

Discuss
Answer: (b).Careful analysis before the system is built Explanation:The waterfall model places a significant emphasis on a careful analysis before the system is actually built in order to prevent putting much energy into constructing a system which later turns out not to satisfy the user’s requirements.
Q205.
What are the key values of the agile movement in software development?

a.

Individuals and interactions over processes and tools

b.

Working software over comprehensive documentation

c.

Customer collaboration over contract negotiation

d.

All of the above

Discuss
Answer: (d).All of the above Explanation:The Agile Manifesto published in 2001 by a group of well-known pioneers in the field lists the key values of the agile movement as: Individuals and interactions over processes and tools, working software over comprehensive documentation, customer collaboration over contract negotiation, and responding to change over following a plan.
Q206.
What is the main difference between prototyping and agile methods?

a.

Agile methods involve the users in every step taken

b.

Agile methods assume the world is fundamentally chaotic

c.

The term "prototyping" suggests something intermediate and temporary

d.

All of the above

Discuss
Answer: (d).All of the above Explanation:Agile methods involve the users in every step taken, assume the world is fundamentally chaotic, and the term "prototyping" suggests something intermediate and temporary
Q207.
What is the main focus of agile methods?

a.

To deliver a final system that meets user's requirements

b.

To deliver value to the customer as quickly as possible

c.

To follow a strict plan and process

d.

To create comprehensive documentation

Discuss
Answer: (b).To deliver value to the customer as quickly as possible Explanation:The main focus of Agile methods is to deliver value to the customer as quickly as possible and not bother about extensive plans and processes that won’t be followed anyway.
Q208.
What is the main difference between Agile methods and Waterfall model?

a.

Agile methods are people oriented while Waterfall model is process oriented

b.

Agile methods rely on the tacit knowledge of the people involved while Waterfall model rely on extensive documentation

c.

Agile methods are incremental while Waterfall model is strictly sequential

d.

All of the above

Discuss
Answer: (d).All of the above Explanation:Agile methods are people-oriented and rely on the tacit knowledge of the people involved, while Waterfall model is process-oriented and rely on extensive documentation. Agile methods are incremental while Waterfall model is strictly sequential.
Q209.
What is the main advantage of using a prototype in software development?

a.

It allows for the testing of multiple copies of the product

b.

It allows for the development of a working model of the software system

c.

It allows for the development of a software system with high functionality

d.

It allows for the development of a software system with low costs

Discuss
Answer: (b).It allows for the development of a working model of the software system Explanation:A prototype in software development is a working model of the software system that emphasizes certain aspects, such as usability.
Q210.
What are the costs associated with developing a software prototype?

a.

High

b.

Low

c.

Medium

d.

Depends on the project

Discuss
Answer: (b).Low Explanation:The costs associated with developing a software prototype are low because making multiple copies of the product is almost free in software development.
