In the context of the SDLC, how does the iterative model differ from the waterfall model in terms of phases and flexibility?
- The iterative model has fewer phases
- The iterative model is linear
- The waterfall model is iterative
- The waterfall model is more flexible
The iterative model differs from the waterfall model as it allows for iterative and repetitive development cycles, revisiting and refining phases as needed. In contrast, the waterfall model is more linear, with a strict sequence of phases. This makes the iterative model more flexible and adaptive, while the waterfall model is more rigid in its approach.
What is the primary focus of functional requirements in software development?
- Design aesthetics
- System performance
- Technical implementation
- User interactions
Functional requirements primarily focus on defining how the system will interact with users and what actions it should perform, emphasizing user needs and functionality.
You are developing a highly critical financial application where accuracy is paramount. How would Test-Driven Development (TDD) be beneficial in this context?
- TDD allows for rigorous testing after development.
- TDD ensures faster development without compromising accuracy.
- TDD helps in verifying accuracy throughout the development process.
- TDD is unnecessary for accuracy in development.
Test-Driven Development (TDD) ensures that accuracy is maintained by allowing developers to write tests before writing code. This continuous testing helps catch and prevent inaccuracies throughout the development process, making it ideal for highly critical applications.
Configuration Management ensures that all software and hardware components are tracked and _____ consistently throughout their lifecycle.
- Controlled
- Documented
- Ignored
- Upgraded
Configuration Management ensures that all components are tracked and controlled consistently throughout their lifecycle, maintaining consistency and traceability.
In a scenario where a software development team is working on a critical application with tight deadlines, what code review technique could be most efficient to ensure quality while minimizing time delays?
- Formal Inspections
- Lightweight Code Reviews
- No Code Review
- Pair Programming
In this scenario, where time is limited, lightweight code reviews can be the most efficient. They focus on quick and informal reviews, which can help catch critical issues without significant time delays. Lightweight reviews are well-suited for high-pressure projects.
How can adherence to coding standards and style guides impact the maintainability and scalability of a codebase?
- It improves code readability and consistency.
- It increases the chances of runtime errors.
- It limits code creativity and innovation.
- It reduces the need for version control.
Adherence to coding standards and style guides enhances maintainability and scalability by ensuring consistent, readable code that's easier to understand, modify, and scale. It promotes a shared coding style across the team, reducing errors and making collaboration more efficient.
A significant limitation of traditional SDLC models is the difficulty in accommodating _____ once the development has started.
- Documentation changes
- Requirements changes
- Risk management
- Stakeholder feedback
Traditional SDLC models face a significant limitation in accommodating Requirements changes once the development has started. These models follow a sequential approach, making it challenging to incorporate new requirements or changes without disrupting the entire process. Agile methodologies, in contrast, are more flexible and adaptable to changing requirements.
What role does Software Architecture Design play in determining the overall system performance?
- It defines the system's performance attributes.
- It has no impact on performance.
- It only affects hardware performance.
- It solely depends on the development team.
Software Architecture Design plays a crucial role in determining the overall system performance by specifying performance attributes, like speed, scalability, and resource utilization, which guide development efforts for optimal performance.
In Software Architecture Design, the _____ pattern involves dividing the system into interconnected components to improve modifiability and scalability.
- Component-Based
- Facade
- MVC
- Singleton
In Software Architecture Design, the "Component-Based" pattern involves dividing the system into interconnected components, enhancing modifiability and scalability.
You are part of a team responsible for the uptime and reliability of a critical e-commerce platform. How would monitoring and logging practices assist in ensuring the platform's availability and performance?
- They detect performance issues
- They ensure data privacy
- They have no impact
- They help identify new features
Monitoring and logging practices are crucial for detecting performance issues in a critical e-commerce platform. They provide insights into system behavior, errors, and bottlenecks, helping maintain uptime and reliability.
