In Agile development, how are user stories used during the sprint planning?
- They are not used in sprint planning.
- User stories are broken down into tasks for implementation during the sprint.
- User stories are created only after the sprint planning is completed.
- User stories are used for sprint planning to set the sprint goals and priorities.
In Agile development, user stories are used during sprint planning to define the scope of work for the upcoming sprint. They help set the sprint goals, determine priorities, and allocate tasks among the development team, ensuring that the team knows what needs to be accomplished in the sprint.
In database design, how does indexing improve query performance?
- It has no impact on query performance.
- It improves query performance.
- It only improves data storage.
- It slows down query performance.
Indexing in database design helps in faster data retrieval by creating a data structure that maps key values to their locations in the database. This significantly speeds up query performance, especially for large datasets.
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.
Source Code Management tools like Git allow developers to _______ changes, providing a history of code modifications.
- Commit
- Deploy
- Ignore
- Reject
Source Code Management tools like Git allow developers to "Commit" changes, which records the modifications made to the code, providing a history for version control.
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.
