A _______ is a tool or set of guidelines used by developers to maintain a consistent coding style across a codebase.
- Compiler
- Debugger
- Linter
- Refactoring Tool
A linter is a tool used by developers to enforce and maintain a consistent coding style across a codebase. It helps identify and flag coding issues and violations of coding standards.
After a data breach, an organization is working to restore its services. Which phase of the incident response process is the organization currently in?
- Containment
- Eradication and Recovery
- Identification
- Preparation
After a data breach, the organization is in the "Eradication and Recovery" phase of the incident response process, where they work to eliminate the threat and restore services.
The _____ maintenance model involves making changes to a system to add new features or meet additional requirements.
- Adaptive
- Corrective
- Perfective
- Preventive
The Perfective maintenance model focuses on making improvements to a system by adding new features or enhancing existing ones to meet additional requirements.
What is the primary purpose of monitoring and logging in a software application?
- To decrease application cost
- To enhance user experience
- To identify and diagnose issues
- To slow down the application's performance
Monitoring and logging are essential for identifying and diagnosing issues in a software application. They provide insights into performance, errors, and usage patterns, helping improve software quality and user satisfaction.
During which phase of the SDLC are potential risks identified and analyzed?
- Design Phase
- Requirements Phase
- Risk Assessment Phase
- Testing Phase
The Risk Assessment Phase is where potential risks and issues are identified and analyzed. It's crucial for proactively managing risks throughout the project's lifecycle.
You are a product manager working on a new mobile application. How would you utilize user stories and use cases to gather and document requirements effectively?
- User stories and use cases are not useful for gathering requirements.
- User stories and use cases are the same and can be used interchangeably for any requirement.
- User stories capture functional requirements, while use cases document non-functional requirements.
- User stories document non-functional requirements, while use cases capture functional requirements.
User stories and use cases serve distinct purposes in gathering requirements. User stories focus on functional requirements and describe what the software should do from a user's perspective. Use cases, on the other hand, capture non-functional requirements, such as system interactions and behavior. They help ensure a comprehensive understanding of how the system should work in different scenarios.
In a project to develop a financial software system, how would requirement validation help in ensuring that the software complies with financial regulations and user needs?
- It eliminates the need for testing.
- It ensures that requirements align with regulations and user needs.
- It focuses on marketing strategies.
- It speeds up the development process.
Requirement validation in a financial software project helps ensure that the software aligns with financial regulations and user needs. It provides a systematic way to check that the requirements meet the necessary criteria, reducing compliance risks and satisfying user expectations.
In the context of the SDLC, how does the iterative model differ from the waterfall model in terms of phases and flexibility?
- The iterative model has fewer phases
- The iterative model is linear
- The waterfall model is iterative
- The waterfall model is more flexible
The iterative model differs from the waterfall model as it allows for iterative and repetitive development cycles, revisiting and refining phases as needed. In contrast, the waterfall model is more linear, with a strict sequence of phases. This makes the iterative model more flexible and adaptive, while the waterfall model is more rigid in its approach.
What is the primary focus of functional requirements in software development?
- Design aesthetics
- System performance
- Technical implementation
- User interactions
Functional requirements primarily focus on defining how the system will interact with users and what actions it should perform, emphasizing user needs and functionality.
You are developing a highly critical financial application where accuracy is paramount. How would Test-Driven Development (TDD) be beneficial in this context?
- TDD allows for rigorous testing after development.
- TDD ensures faster development without compromising accuracy.
- TDD helps in verifying accuracy throughout the development process.
- TDD is unnecessary for accuracy in development.
Test-Driven Development (TDD) ensures that accuracy is maintained by allowing developers to write tests before writing code. This continuous testing helps catch and prevent inaccuracies throughout the development process, making it ideal for highly critical applications.
