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.
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.
After a data breach, an organization is working to restore its services. Which phase of the incident response process is the organization currently in?
- Containment
- Eradication and Recovery
- Identification
- Preparation
After a data breach, the organization is in the "Eradication and Recovery" phase of the incident response process, where they work to eliminate the threat and restore services.
The _____ maintenance model involves making changes to a system to add new features or meet additional requirements.
- Adaptive
- Corrective
- Perfective
- Preventive
The Perfective maintenance model focuses on making improvements to a system by adding new features or enhancing existing ones to meet additional requirements.
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.
How can incorporating Continuous Integration (CI) enhance the code review process?
- It automates testing and code integration, improving code review
- It delays the code review process
- It introduces manual and time-consuming processes
- It prevents collaboration between team members
Continuous Integration (CI) automates testing and code integration, which enhances the code review process by ensuring that the code is always in a testable state. It fosters collaboration and accelerates the review process.
