A software development team is working on a project with frequent changes in design requirements. Which prototyping tool would be best suited for quickly iterating and testing design changes?
- High-Fidelity Interactive Prototyping
- Low-Fidelity Paper Prototyping
- UML Diagrams
- Wireframing
High-Fidelity Interactive Prototyping tools, like mockups and interactive prototypes, are best suited for quickly iterating and testing design changes, making them ideal for projects with evolving design requirements.
In a project following Agile methodology, how would a team ensure that both functional and non-functional requirements are considered and implemented during the development sprints?
- Agile focuses on functional requirements, and non-functional requirements are addressed in later stages.
- Agile incorporates both functional and non-functional requirements by including them in user stories and tasks during each sprint.
- Agile teams rely solely on non-functional requirements documentation.
- Non-functional requirements are ignored in Agile projects.
Agile teams ensure that both functional and non-functional requirements are considered by incorporating them into user stories and tasks. This allows non-functional aspects like security, performance, and compliance to be addressed iteratively throughout the development process, rather than deferring them to later stages.
You are tasked with minimizing downtime during deployment in a highly scalable application. Which CI/CD strategy would be most effective in achieving this?
- Blue-Green Deployment
- Canary Deployment
- Feature Toggles (Feature Flags)
- Rolling Deployment
Blue-Green Deployment is a strategy where you have two identical environments (blue and green), allowing seamless switching with minimal downtime during deployment.
The _____ SOLID principle emphasizes that high-level modules should not depend on low-level modules, but they should depend on abstractions.
- Dependency Inversion
- Interface Segregation
- Liskov Substitution
- Open-Closed
The Dependency Inversion SOLID principle states that high-level modules should not depend on low-level modules; both should depend on abstractions. This promotes the use of interfaces or abstract classes to achieve this separation of concerns, enhancing maintainability and flexibility in the software.
Which of the following best describes the process of Test-Driven Development (TDD)?
- Skip testing altogether
- Write code first, then test
- Write tests first, then code
- Write tests only when necessary
TDD involves writing tests before writing the actual code. These tests are meant to define the expected behavior of the code, and developers implement the code to meet these predefined expectations.
Which software maintenance model is focused on addressing and fixing known errors or issues in a software product?
- Adaptive Maintenance
- Corrective Maintenance
- Perfective Maintenance
- Preventive Maintenance
Corrective Maintenance is centered on fixing known issues and errors in software. It is one of the key aspects of software maintenance. Other models address different aspects of maintenance.
In the context of Configuration Management, what is the significance of maintaining a Configuration Item (CI) record?
- It ensures all team members are trained in configuration management.
- It helps track changes, relationships, and attributes of configuration items.
- It's a formal document of no real value.
- It's only required for large organizations.
Maintaining Configuration Item (CI) records is crucial in Configuration Management. These records track changes, relationships, and attributes of CIs, enabling effective control and traceability throughout the SDLC.
The _____ model in SDLC is characterized by its focus on risk assessment and iterative development.
- Agile
- Spiral
- V-Model
- Waterfall
The Spiral model in SDLC is characterized by its focus on risk assessment and iterative development, making it suitable for complex projects.
What does the acronym SDLC stand for in the context of software development?
- Software Deployment Cycle
- Software Development Loop
- System Development Life Cycle
- Systematic Development
SDLC stands for "System Development Life Cycle." It is a structured approach to software development that defines stages and tasks, ensuring the systematic creation of high-quality software.
What is a limitation faced by organizations when trying to shift from a traditional SDLC approach to Agile methodologies?
- Difficulty in changing organizational culture and mindset.
- Enhanced process control.
- Improved documentation.
- Increased project predictability.
Shifting from traditional SDLC to Agile often faces the limitation of changing the organizational culture and mindset. Agile requires a more flexible, collaborative, and adaptive approach, which can be challenging for organizations used to a more structured and hierarchical culture.
