A software development team is working on creating a new app for a client. The client has a broad idea but is unclear about specific functionalities. Which requirement gathering technique would be most beneficial in this situation?
- Agile Requirements Workshops
- Joint Application Development (JAD)
- Prototyping
- Rapid Application Development (RAD)
In this situation, using a prototyping technique would be most beneficial. Prototypes allow the client to visualize and interact with a preliminary version of the app, helping to clarify and refine specific functionalities before development begins.
A team is developing a web application and wants to ensure that all elements render correctly on different devices and browsers. Which type of testing should they focus on?
- Compatibility Testing
- Performance Testing
- Security Testing
- Usability Testing
To ensure that all elements render correctly on various devices and browsers, the team should focus on Compatibility Testing. This testing checks how well the application functions on different platforms and browsers, ensuring a consistent and user-friendly experience.
The process of _______ involves collecting and determining the needs and functionalities that a software system must provide.
- Coding
- Requirement Gathering
- System Design
- Testing
The process of Requirement Gathering involves collecting and determining the needs and functionalities that a software system must provide. This is a critical phase in the SDLC where all project requirements are documented and analyzed to ensure alignment with stakeholders' expectations.
How does a rolling deployment strategy differ from a Blue-Green deployment in terms of risk and downtime?
- Blue-Green deployment is a riskier approach than rolling deployment
- Rolling deployment and Blue-Green deployment have similar levels of risk and downtime
- Rolling deployment involves more downtime and risk compared to Blue-Green deployment
- Rolling deployment requires a complete infrastructure duplication
Rolling deployments require a complete infrastructure duplication, which can result in more downtime compared to Blue-Green deployments. Blue-Green deployments reduce downtime by switching between two environments seamlessly.
How does Configuration Management contribute to ensuring reproducibility and traceability in software development?
- It automates testing processes
- It manages project schedules and deadlines
- It optimizes database performance
- It tracks code changes and versions
Configuration Management helps in tracking code changes and versions, ensuring that a specific code state can be reproduced. This enhances traceability and the ability to recreate environments and software configurations.
_____ in software maintenance refers to the practice of making code changes to improve performance without altering functionality.
- Debugging
- Enhancement
- Performance tuning
- Refactoring
Performance tuning in software maintenance involves making code changes to improve the software's performance without altering its existing functionality. It optimizes the code's efficiency and execution speed.
How does adhering to the principle of "Keep It Simple, Stupid" (KISS) in coding best practices contribute to software maintainability?
- It increases development time
- It leads to more bugs and errors
- It makes code complex and harder to understand
- It simplifies code, making it easier to maintain
Adhering to the KISS principle simplifies code, making it easier to understand and maintain. Complex code can lead to difficulties in maintaining and debugging.
In the SDLC, which phase involves ensuring that the software meets the specified requirements and is free of bugs?
- Analysis Phase
- Design Phase
- Maintenance Phase
- Testing Phase
The Testing Phase in the SDLC is dedicated to verifying that the software meets specified requirements and is free of bugs. This phase ensures the software's quality and functionality.
In _____ deployment, new features are incrementally rolled out to the user base, allowing for continuous feedback and adjustments.
- Agile
- Incremental
- Prototype
- Waterfall
In Agile deployment, new features are incrementally rolled out to the user base, allowing for continuous feedback and adjustments throughout the development process.
What type of testing is performed to ensure that the individual units or components of a software system are working correctly?
- Acceptance Testing
- Integration Testing
- System Testing
- Unit Testing
Unit Testing is the type of testing performed to verify that individual units or components of a software system work correctly. It focuses on isolated testing of these units to identify and address defects at an early stage.
