How does the Agile methodology address the limitation of inflexibility in traditional SDLC?
- By adding more phases
- By avoiding documentation
- By promoting collaboration
- By reducing the development time
Agile addresses the inflexibility of traditional SDLC by promoting collaboration, frequent communication, and adaptive planning. It allows for changes to be incorporated throughout the development process.
Adherence to the _____ SOLID principle ensures that the software entities should depend on abstractions and not on concretions.
- Dependency Inversion
- Liskov Substitution
- Open-Closed
- Single Responsibility
Adherence to the Dependency Inversion SOLID principle ensures that software entities should depend on abstractions (e.g., interfaces) rather than concrete implementations. This promotes flexibility, extensibility, and the ease of swapping out components without affecting the system's core.
_____ testing can be time-consuming and prone to human error, while _____ testing can quickly execute a large number of tests and is less prone to errors.
- Alpha; Beta
- Manual; Automated
- Unit; Integration
- White-box; Black-box
Manual testing can be time-consuming and prone to human error, while automated testing can quickly execute a large number of tests and is less prone to errors. Automated testing is essential in modern software development for efficiency and reliability.
You are reviewing a colleague's code and notice inconsistencies in naming conventions and indentation. How could adherence to a coding standard or style guide have prevented this?
- Coding standards are unnecessary
- Coding standards create bugs
- Coding standards improve code quality
- Coding standards slow down development
Adhering to a coding standard or style guide can prevent inconsistencies in naming and indentation. Coding standards provide a set of rules and best practices, ensuring code consistency and readability. This enhances code quality, makes maintenance and collaboration easier, and helps avoid common errors caused by inconsistent coding practices.
Why is it important for an organization to have an incident response plan?
- It addresses security breaches and threats
- It enhances employee morale
- It ensures constant monitoring
- It reduces productivity losses
An incident response plan is crucial for addressing security breaches and threats effectively. It helps minimize damage, safeguard sensitive data, and maintain the organization's reputation and trust. This plan outlines the steps to take when incidents occur.
A significant limitation of traditional SDLC models is the difficulty in accommodating _____ once the development has started.
- Documentation changes
- Requirements changes
- Risk management
- Stakeholder feedback
Traditional SDLC models face a significant limitation in accommodating Requirements changes once the development has started. These models follow a sequential approach, making it challenging to incorporate new requirements or changes without disrupting the entire process. Agile methodologies, in contrast, are more flexible and adaptable to changing requirements.
What role does Software Architecture Design play in determining the overall system performance?
- It defines the system's performance attributes.
- It has no impact on performance.
- It only affects hardware performance.
- It solely depends on the development team.
Software Architecture Design plays a crucial role in determining the overall system performance by specifying performance attributes, like speed, scalability, and resource utilization, which guide development efforts for optimal performance.
In Software Architecture Design, the _____ pattern involves dividing the system into interconnected components to improve modifiability and scalability.
- Component-Based
- Facade
- MVC
- Singleton
In Software Architecture Design, the "Component-Based" pattern involves dividing the system into interconnected components, enhancing modifiability and scalability.
You are part of a team responsible for the uptime and reliability of a critical e-commerce platform. How would monitoring and logging practices assist in ensuring the platform's availability and performance?
- They detect performance issues
- They ensure data privacy
- They have no impact
- They help identify new features
Monitoring and logging practices are crucial for detecting performance issues in a critical e-commerce platform. They provide insights into system behavior, errors, and bottlenecks, helping maintain uptime and reliability.
_____ can be used to visualize and specify how external actors interact with a system to achieve specific goals.
- Flowcharts
- Prototypes
- Use Cases
- User Stories
Use cases can be used to visualize and specify how external actors interact with a system to achieve specific goals, helping in requirements analysis and design.
