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.
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.
How does the concept of polymorphism in Object-Oriented Programming enhance code reusability?
- It allows objects of different classes to be treated as objects of a common base class.
- It eliminates the need for inheritance.
- It promotes static binding of methods.
- It restricts the ability to extend and modify classes.
Polymorphism in OOP enhances code reusability by allowing objects of different classes to be treated as objects of a common base class. This enables more flexible and extensible code as you can work with various objects without knowing their specific types, which encourages reuse and simplifies code maintenance.
A software development team notices that the requirements are changing frequently. Which limitation of traditional SDLC is this situation highlighting, and how can Agile methodologies provide a solution?
- Inflexibility to changing requirements
- Lack of customer involvement throughout development
- Lack of documentation and planning
- Poor quality of code produced
The changing requirements highlight the inflexibility of traditional SDLC models. Agile methodologies provide a solution through iterative development and frequent customer feedback, allowing adaptation to evolving requirements.
The _____ phase in SDLC involves creating detailed specifications about how the software system should function and look.
- Analysis
- Design
- Implementation
- Requirements
The Design phase in SDLC involves creating detailed specifications about how the software system should function and look, including user interfaces and system architecture.
