Which technique involves visualizing and detailing the system's functionalities in the form of user actions and system responses during requirement documentation?
- Data Modeling
- Entity-Relationship Diagrams
- Network Diagrams
- Use Case Modeling
Use Case Modeling is a technique that visualizes the system's functionalities by describing user actions and system responses. It helps in understanding how the system will interact with users and other components.
A software development team is working on a project with frequent changes in design requirements. Which prototyping tool would be best suited for quickly iterating and testing design changes?
- High-Fidelity Interactive Prototyping
- Low-Fidelity Paper Prototyping
- UML Diagrams
- Wireframing
High-Fidelity Interactive Prototyping tools, like mockups and interactive prototypes, are best suited for quickly iterating and testing design changes, making them ideal for projects with evolving design requirements.
In a project following Agile methodology, how would a team ensure that both functional and non-functional requirements are considered and implemented during the development sprints?
- Agile focuses on functional requirements, and non-functional requirements are addressed in later stages.
- Agile incorporates both functional and non-functional requirements by including them in user stories and tasks during each sprint.
- Agile teams rely solely on non-functional requirements documentation.
- Non-functional requirements are ignored in Agile projects.
Agile teams ensure that both functional and non-functional requirements are considered by incorporating them into user stories and tasks. This allows non-functional aspects like security, performance, and compliance to be addressed iteratively throughout the development process, rather than deferring them to later stages.
You are tasked with minimizing downtime during deployment in a highly scalable application. Which CI/CD strategy would be most effective in achieving this?
- Blue-Green Deployment
- Canary Deployment
- Feature Toggles (Feature Flags)
- Rolling Deployment
Blue-Green Deployment is a strategy where you have two identical environments (blue and green), allowing seamless switching with minimal downtime during deployment.
The _____ SOLID principle emphasizes that high-level modules should not depend on low-level modules, but they should depend on abstractions.
- Dependency Inversion
- Interface Segregation
- Liskov Substitution
- Open-Closed
The Dependency Inversion SOLID principle states that high-level modules should not depend on low-level modules; both should depend on abstractions. This promotes the use of interfaces or abstract classes to achieve this separation of concerns, enhancing maintainability and flexibility in the software.
Which aspect of database design ensures that there is minimal redundancy and dependency by organizing fields and tables of a database?
- Data Serialization
- Data Validation
- Database Fragmentation
- Database Normalization
Database Normalization is the process of organizing data in a database to minimize redundancy and dependency, which leads to a more efficient and reliable database structure.
One of the limitations of traditional SDLC is that testing is often relegated to the _____ phase, which can lead to delays.
- Development
- Planning
- Requirements
- Testing
One of the limitations of traditional SDLC is that testing is often relegated to the Development phase. This means that testing occurs late in the cycle, which can lead to delays and increased costs due to the identification and rectification of defects late in the process. It is more effective to incorporate testing earlier in the process to catch issues sooner.
What is the main purpose of using a testing framework like JUnit or TestNG?
- To automate unit and integration tests
- To create user interfaces
- To manage software development projects
- To write software documentation
JUnit and TestNG are testing frameworks that automate the execution of unit and integration tests, making it easier to validate code and improve software quality.
Which limitation of SDLC is highlighted by the need for extensive documentation in every phase?
- Excessive emphasis on user involvement.
- Lack of flexibility and adaptability.
- Lack of structure in SDLC.
- Potential for scope creep.
The extensive documentation requirement in traditional SDLC models underscores the limitation of rigidity and lack of adaptability to changing project needs, making it challenging to manage evolving requirements.
How do tools like Selenium WebDriver facilitate automated testing in software development?
- They automate the entire software development process.
- They only work with Java applications.
- They provide a framework for automating web application testing.
- They require manual test case creation.
Selenium WebDriver is a tool that provides a framework for automating web application testing. It allows testers to write test scripts in various programming languages and automate the testing of web applications across different browsers.
