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.
In _______ programming, functions are treated as first-class citizens, allowing them to be passed as arguments and returned from other functions.
- Functional
- Imperative
- Object-Oriented
- Procedural
In functional programming, functions are treated as first-class citizens, which means they can be passed as arguments and returned from other functions. This allows for powerful and flexible programming techniques.
A software development team is using a Requirement Management Tool to keep track of changes in requirements. How does this tool contribute to the successful validation of requirements?
- It automates coding.
- It designs the user interface.
- It generates test data.
- It tracks requirement changes.
A Requirement Management Tool helps track and manage changes in requirements. This is essential for validation, as it ensures that all changes are documented, reviewed, and validated, leading to a clear understanding of the requirements and their impact on the project.
How does an effective incident response plan minimize the impact of a security breach?
- By escalating the breach to authorities
- By ignoring the breach
- By quickly reporting the breach
- By recovering lost data
Effective incident response plans minimize the impact of a security breach by promptly detecting, reporting, and addressing the breach, reducing the window of opportunity for attackers and preventing further damage.
The _____ phase of the SDLC involves translating the software design into source code.
- Development
- Maintenance
- Planning
- Testing
The Development phase is where the software design is transformed into source code, where the actual development of the software takes place.
