Which prototyping model is characterized by building a partial implementation of a system and then progressively expanding and refining it?
- Agile Model
- Incremental Model
- Spiral Model
- Waterfall Model
The Incremental Prototyping Model involves building a partial implementation of the system and then progressively expanding and refining it by adding new features or functionality.
What challenges might a development team face when implementing pair programming as a code review technique?
- Improved code quality and efficiency
- Increased productivity and quality issues
- Reduced collaboration
- Reduced knowledge sharing between team members
Pair programming, as a code review technique, may lead to reduced knowledge sharing between team members. While it can enhance code quality and efficiency, it may challenge knowledge distribution.
A team is developing a real-time gaming application. During which type of testing would they assess the application's responsiveness and stability under peak user load?
- Integration Testing
- Performance Testing
- System Testing
- Unit Testing
In this scenario, the team needs to assess the application's responsiveness and stability under peak user load, which is the primary goal of performance testing. Performance testing evaluates system behavior under different conditions and helps identify bottlenecks and issues.
How can inconsistencies in requirements be identified during the validation process?
- Ignoring inconsistencies.
- Manual review by developers.
- Using a different validation tool.
- Using automated analysis tools.
Inconsistencies in requirements can be identified during validation through manual review by developers. Ignoring inconsistencies can lead to issues, making manual review critical.
What is the primary goal of software patch management?
- Enhancing user interface
- Fixing software bugs
- Improving hardware
- Reducing software features
The primary goal of software patch management is to fix software bugs and vulnerabilities. Patches are updates that address security flaws and issues in software, enhancing its reliability and security.
How does the concept of 'Infrastructure as Code' integrate with CI/CD pipelines?
- It automates infrastructure provisioning.
- It provides human-readable infrastructure.
- It removes the need for CI/CD.
- It slows down development cycles.
'Infrastructure as Code' integrates with CI/CD by automating the provisioning and management of infrastructure resources, ensuring consistency and reliability in the deployment process. It accelerates development cycles.
A team is developing a complex system with multiple interacting components. Which programming paradigm would allow them to model the system as a collection of independent entities with distinct state and behavior?
- Event-driven programming
- Functional programming
- Object-oriented programming
- Procedural programming
Object-oriented programming allows modeling a complex system as a collection of independent entities with distinct state and behavior. It promotes encapsulation, inheritance, and polymorphism, which enable the creation of modular, reusable, and maintainable code, aligning well with systems consisting of multiple interacting components.
Which SOLID principle suggests that a derived class must be substitutable for its base class?
- Dependency Inversion Principle
- Liskov Substitution Principle
- Open/Closed Principle
- Single Responsibility Principle
The Liskov Substitution Principle (LSP) is the SOLID principle that suggests that a derived class must be substitutable for its base class without affecting the correctness of the program. It ensures that inheritance and polymorphism are used correctly.
What benefits does using an SDLC bring to large-scale projects with intricate requirements and complex solutions?
- It eliminates the need for project management and documentation
- It increases development speed and decreases cost
- It provides a structured approach, ensuring better control, visibility, and quality
- It simplifies complex requirements and provides a one-size-fits-all solution
For large-scale projects with intricate requirements and complex solutions, SDLC offers a structured approach that ensures better control, visibility, and quality. It helps manage complexity and mitigate risks associated with such projects.
How does a well-designed Software Architecture contribute to the ease of integration in a continuously evolving system?
- It creates rigid boundaries between components
- It discourages the use of APIs and third-party services
- It isolates integration concerns
- It limits adaptability
A well-designed software architecture isolates integration concerns, making it easier to adapt and evolve the system over time. It doesn't create rigid boundaries but allows flexibility by isolating integration logic and reducing dependencies. This facilitates the incorporation of new technologies and changes without disrupting the entire system.
