When comparing Agile and traditional SDLC models, how does the approach to risk management differ?
- Agile embraces risk and adapts to it.
- Agile focuses on risk avoidance.
- Traditional SDLC models have no risk management.
- Traditional SDLC models have strict risk planning.
In Agile, risk management differs as it embraces risk and adapts to changing circumstances, while traditional SDLC models often employ strict risk planning. Agile manages risk through continuous adaptation, fostering innovation and rapid response.
In code review, what is the purpose of using automated tools to check code against certain standards and rules?
- To eliminate the need for manual review.
- To find and report issues efficiently.
- To increase code complexity.
- To slow down the review process.
Automated tools in code review are used to efficiently check code against standards and rules. They help identify issues such as coding style violations, potential bugs, and security vulnerabilities, streamlining the review process and ensuring code quality.
Which stage of the SDLC typically involves the validation of requirements to ensure they are clear and achievable?
- Design Phase
- Planning Phase
- Requirements Phase
- Testing Phase
The Requirements Phase in the SDLC typically involves the validation of requirements to ensure they are clear, complete, and achievable. This phase sets the foundation for the entire project.
In Functional Programming, side effects are avoided by emphasizing _______ and pure functions.
- Encapsulation
- Immutability
- Inheritance
- Mutability
In Functional Programming, side effects are avoided by emphasizing immutability and pure functions. Immutability ensures that data doesn't change after creation, and pure functions produce the same output for the same input, without side effects.
In complex database design, _____ helps in ensuring data consistency and integrity across multiple tables.
- Denormalization
- Normalization
- Replication
- Validation
In complex database design, _____, specifically "Normalization," plays a crucial role in ensuring data consistency and integrity across multiple tables. It involves organizing data to reduce redundancy and dependency issues.
What is the primary advantage of using the Blue-Green deployment strategy?
- It allows for easy rollback.
- It minimizes server infrastructure costs.
- It provides a simple release process.
- It reduces development time.
Blue-Green deployment is advantageous because it allows for a quick and risk-free rollback to the previous version in case of issues, ensuring minimal downtime and reduced risks.
What is the main purpose of a user story in Agile methodologies?
- To assign tasks to team members.
- To capture end-user needs.
- To describe technical details.
- To track project timelines.
A user story in Agile serves to capture end-user needs and requirements in a simple, non-technical manner, fostering collaboration and understanding among team members.
A team is developing a safety-critical system. Which code review techniques would be most appropriate to ensure the reliability and correctness of the code?
- Formal Inspections
- Lightweight Code Reviews
- No Code Review
- Pair Programming
In the context of safety-critical systems, where reliability and correctness are paramount, formal inspections are the most appropriate code review technique. Formal inspections involve rigorous, structured reviews that can uncover potential issues and defects in the code that might be missed in less formal processes.
What considerations should be made when choosing a software maintenance model for a legacy system?
- Compatibility with existing tools and systems.
- Cost is the only factor.
- Ignore user feedback.
- Only consider the latest technology trends.
When choosing a software maintenance model for a legacy system, compatibility with existing tools and systems is crucial. Cost, user feedback, and technology trends are also important but secondary factors.
What is the main purpose of validating requirements in a software development project?
- To create user documentation
- To design the user interface
- To eliminate project risks
- To identify and resolve issues early
Validating requirements in a software development project is essential to identify and resolve issues and discrepancies early in the project, ensuring that the final product meets the desired objectives and quality standards.
