System Design and SDLC Models

What is the main characteristic of the Agile model?

• Iterative development and flexibility in response to change.
• Single-phase development with no iterations.
• Focus on extensive documentation before development.
• Strict adherence to a predefined plan.

In which SDLC model do requirements typically evolve through collaboration?

• V-Model
• Waterfall
• Agile
• Spiral

Which SDLC model emphasizes a feedback loop for constant improvement?

• RAD

• Spiral
• Waterfall
• V-Model

What phase comes directly after the Design phase in the V-Model?

• Coding

• Testing
• Maintenance
• Implementation

In the Spiral model, what is the purpose of the risk analysis phase?

• To enhance team communication during development.
• To define the project scope and objectives.
• To identify and manage potential risks in the project.
• To create a detailed project schedule.

Which of the following models is considered a variation of the Waterfall model focused on risk assessment?

• Incremental model
• Spiral model
• Agile model
• V-Model

In the RAD (Rapid Application Development) model, how is user feedback primarily gathered?

• Through extensive documentation

• By analyzing market trends.
• Via prototypes

• Using automated testing tools.

What is a major disadvantage of the Waterfall model?

• Early detection of potential issues in the project.
• Clear and defined project phases.
• High adaptability to changes during the development process.
• Inflexibility to changes during the development process.

Which SDLC model pairs development and testing closely together?

• Waterfall
• V-Model
• Spiral
• Agile

What is the primary goal of the system design process?

• To create a blueprint that meets system requirements and constraints.
• To analyze competitor systems and their features.
• To conduct user interviews for feedback.
• To develop a marketing strategy for the system.
