Which model can be selected if user is involved in all the phases of SDLC?
- A.
Waterfall Model
- B.
Prototyping Model
- C.
RAD Model
- D.
All of the above
Correct Answer
C. RAD ModelExplanation
The RAD (Rapid Application Development) Model can be selected if the user is involved in all the phases of the SDLC (Software Development Life Cycle). This model emphasizes iterative development and active user involvement throughout the process. It allows for quick prototyping and feedback, enabling users to provide continuous input and make necessary changes at each stage. Therefore, the RAD Model is suitable when user involvement is crucial in every phase of the SDLC.Rate this question:

Which of the following life cycle model can be chosen if the development team has less experience on similar projects?
- A.
Spiral
- B.
Waterfall
- C.
RAD
- D.
Iterative Enhancement Model
Correct Answer
A. SpiralExplanation
The Spiral life cycle model can be chosen if the development team has less experience on similar projects because it is a flexible model that allows for iterative development and incorporates risk management. The model involves a series of iterations, with each iteration building upon the previous one. This allows the team to learn from each iteration and make necessary adjustments as they gain more experience. Additionally, the Spiral model emphasizes risk analysis and mitigation, which is beneficial when the team has less experience and may encounter unforeseen challenges.Rate this question:

If you were a lead developer of a software company and you are asked to submit a project/product within a stipulated time-frame with no cost barriers, which model would you select?
- A.
Waterfall
- B.
Spiral
- C.
RAD
- D.
Incremental
Correct Answer
C. RADExplanation
RAD (Rapid Application Development) would be the most suitable model to select in this scenario. RAD is a software development approach that emphasizes rapid prototyping and iterative development. It allows for quick delivery of a functional product by focusing on user feedback and involvement throughout the development process. With no cost barriers, RAD would enable the lead developer to quickly develop and deliver a high-quality product within the stipulated time-frame, ensuring customer satisfaction and meeting project goals efficiently.Rate this question:

The Incremental Model is a result of combination of elements of which two models?
- A.
Build & FIX Model & Waterfall Model
- B.
Linear Model & RAD Model
- C.
Linear Model & Prototyping Model
- D.
Waterfall Model & RAD Model
Correct Answer
C. Linear Model & Prototyping ModelExplanation
The Incremental Model is a result of combining elements from the Linear Model and the Prototyping Model. The Linear Model emphasizes a sequential and linear approach to software development, while the Prototyping Model focuses on creating prototypes to gather user feedback and refine the final product. By combining these two models, the Incremental Model allows for iterative development, where the software is built and refined in increments, with each increment being a combination of linear development and prototyping. This approach helps to minimize risks and allows for early feedback and adjustments throughout the development process.Rate this question:

What are the characteristics of software?
- A.
Software is developed or engineered; it is not manufactured in the classical sense.
- B.
Software doesn’t “ wear out ”.
- C.
Software can be custom built or custom build.
- D.
All mentioned above
Correct Answer
A. Software is developed or engineered; it is not manufactured in the classical sense.Explanation
The given answer correctly states that software is developed or engineered, not manufactured in the classical sense. This means that software is not physically produced like a tangible product, but rather created through a process of designing, coding, and testing. This characteristic distinguishes software from physical goods and highlights the unique nature of its development process.Rate this question:

Software Engineering is defined as systematic, disciplined and quantifiable approach for the development, operation and maintenance of software.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Software Engineering is defined as a systematic, disciplined, and quantifiable approach for the development, operation, and maintenance of software. This means that software engineering follows a structured and organized process to ensure that software is developed, deployed, and maintained in a controlled and measurable manner. It emphasizes the use of methodologies, tools, and techniques to manage the software development life cycle effectively. Therefore, the statement "True" is correct as it accurately describes the definition of software engineering.Rate this question:

Software quality assurance is an umbrella activity.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Software quality assurance is an umbrella activity because it encompasses various processes and activities that ensure the quality of software throughout its development lifecycle. It includes activities like requirement analysis, test planning, test execution, defect tracking, and reporting. These activities are performed to ensure that the software meets the specified requirements, is free from defects, and delivers the desired level of quality. By being an umbrella activity, software quality assurance ensures that all the necessary quality-related activities are carried out systematically and consistently, resulting in a high-quality software product.Rate this question:

The spiral model was originally proposed by
- A.
IBM
- B.
Barry Boehm
- C.
Pressman
- D.
Royce
Correct Answer
B. Barry BoehmExplanation
The spiral model was originally proposed by Barry Boehm. This model is a software development process that combines elements of both waterfall and iterative development models. It emphasizes risk management and allows for incremental development and frequent feedback from stakeholders. Barry Boehm, an American software engineer, introduced the spiral model in 1986 as a way to address the challenges of developing complex and large-scale software systems.Rate this question:

Identify the disadvantage of Spiral Model.
- A.
Doesn’t work well for smaller projects
- B.
High amount of risk analysis
- C.
Strong approval and documentation control
- D.
Additional Functionality can be added at a later date
Correct Answer
A. Doesn’t work well for smaller projectsExplanation
The disadvantage of the Spiral Model is that it doesn't work well for smaller projects. This means that the model may not be suitable or efficient for projects with limited scope or resources. The Spiral Model is typically used for large-scale and complex projects where there is a need for iterative development and risk management. However, for smaller projects, a simpler and more streamlined approach may be more appropriate.Rate this question:

SDLC Models are adopted as per requirements of development process. It may vary Software-to-software to ensuring which model is suitable.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The explanation for the given correct answer is that SDLC (Software Development Life Cycle) models are indeed adopted based on the requirements of the development process. Different software projects may have different needs and constraints, and therefore, different SDLC models may be more suitable for each project. The choice of SDLC model depends on factors such as project size, complexity, timeline, budget, and team size. Therefore, it is true that the selection of SDLC models can vary from software to software to ensure the most appropriate model is used.Rate this question:

Company has latest computers and state-of the- art software tools, so we shouldn’t worry about the quality of the product.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
The statement suggests that the quality of the product is not a concern because the company has the latest computers and state-of-the-art software tools. However, having advanced technology does not guarantee product quality. Quality depends on various factors such as the skills and expertise of the employees, proper testing and quality control processes, and adherence to industry standards. Therefore, we should not assume that the product will be of high quality based solely on the company's technological resources.Rate this question:
