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.
In Object-Oriented Programming, the concept of _______ allows an object to take on multiple forms.
- Abstraction
- Encapsulation
- Inheritance
- Polymorphism
Polymorphism in Object-Oriented Programming allows an object to take on multiple forms. It enables objects of different classes to be treated as objects of a common superclass, promoting flexibility and extensibility in software design.
_____ management involves systematically tracking, testing, and applying updates and patches to software applications and systems.
- Change
- Configuration
- Patch
- Risk
Change management involves systematically tracking, testing, and applying updates and patches to software applications and systems to ensure the stability and security of the environment.
Continuous _____ ensures that software changes are automatically tested and deployed to production environments.
- Deployment
- Integration
- Integration
- Testing
Continuous Deployment ensures that software changes are automatically tested and deployed to production environments, promoting a faster and more reliable release process.
A _______ is a tool or set of guidelines used by developers to maintain a consistent coding style across a codebase.
- Compiler
- Debugger
- Linter
- Refactoring Tool
A linter is a tool used by developers to enforce and maintain a consistent coding style across a codebase. It helps identify and flag coding issues and violations of coding standards.
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.
