Which of the following is a characteristic of the Waterfall model?

• Iterative development

• Parallel development

• Sequential flow

• User involvement at all stages

The Prototype model is most suitable when:

• Requirements are well-defined

• Requirements are unclear or changing

• The project follows a strict sequence

• The budget is fixed and small

The Spiral model incorporates features of which two models?

• Waterfall and Prototype

• Prototype and Agile

• Agile and RAD

• Waterfall and Incremental

The main objective of the Evolutionary model is:

• Delivering a final product in a single cycle

• Gradually evolving the software through multiple releases

• Ignoring changes in requirements

• Ensuring a rigid development process

Which of the following models is best suited for risk management?

• Waterfall Model

• Prototype Model

• Spiral Model

• V-Model

The Waterfall model is best suited for projects where:

• Requirements are expected to change frequently

• Early risk assessment is needed

• Clear and well-defined requirements exist

• Incremental deliveries are required

The major drawback of the Prototype model is:

• High cost due to rework

• Rigid structure

• Inability to handle changing requirements

• No user feedback is taken

In the Spiral model, each loop represents:

• A complete version of the software

• A development phase and risk assessment

• A prototype

• A debugging cycle

The Evolutionary model is also known as:

• Incremental Model

• Phased Model

• V-Model

• None of the above

Which SDLC model is best suited for projects with unknown risks?

• Waterfall Model

• Agile Model

• Spiral Model

• V-Model
