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 prototyping model is characterized by building a partial implementation of a system and then progressively expanding and refining it?
- Agile Model
- Incremental Model
- Spiral Model
- Waterfall Model
The Incremental Prototyping Model involves building a partial implementation of the system and then progressively expanding and refining it by adding new features or functionality.
What challenges might a development team face when implementing pair programming as a code review technique?
- Improved code quality and efficiency
- Increased productivity and quality issues
- Reduced collaboration
- Reduced knowledge sharing between team members
Pair programming, as a code review technique, may lead to reduced knowledge sharing between team members. While it can enhance code quality and efficiency, it may challenge knowledge distribution.
A team is developing a real-time gaming application. During which type of testing would they assess the application's responsiveness and stability under peak user load?
- Integration Testing
- Performance Testing
- System Testing
- Unit Testing
In this scenario, the team needs to assess the application's responsiveness and stability under peak user load, which is the primary goal of performance testing. Performance testing evaluates system behavior under different conditions and helps identify bottlenecks and issues.
How can inconsistencies in requirements be identified during the validation process?
- Ignoring inconsistencies.
- Manual review by developers.
- Using a different validation tool.
- Using automated analysis tools.
Inconsistencies in requirements can be identified during validation through manual review by developers. Ignoring inconsistencies can lead to issues, making manual review critical.
What is the primary goal of software patch management?
- Enhancing user interface
- Fixing software bugs
- Improving hardware
- Reducing software features
The primary goal of software patch management is to fix software bugs and vulnerabilities. Patches are updates that address security flaws and issues in software, enhancing its reliability and security.
Which of the following best describes the process of Test-Driven Development (TDD)?
- Skip testing altogether
- Write code first, then test
- Write tests first, then code
- Write tests only when necessary
TDD involves writing tests before writing the actual code. These tests are meant to define the expected behavior of the code, and developers implement the code to meet these predefined expectations.
Which software maintenance model is focused on addressing and fixing known errors or issues in a software product?
- Adaptive Maintenance
- Corrective Maintenance
- Perfective Maintenance
- Preventive Maintenance
Corrective Maintenance is centered on fixing known issues and errors in software. It is one of the key aspects of software maintenance. Other models address different aspects of maintenance.
In the context of Configuration Management, what is the significance of maintaining a Configuration Item (CI) record?
- It ensures all team members are trained in configuration management.
- It helps track changes, relationships, and attributes of configuration items.
- It's a formal document of no real value.
- It's only required for large organizations.
Maintaining Configuration Item (CI) records is crucial in Configuration Management. These records track changes, relationships, and attributes of CIs, enabling effective control and traceability throughout the SDLC.
The _____ model in SDLC is characterized by its focus on risk assessment and iterative development.
- Agile
- Spiral
- V-Model
- Waterfall
The Spiral model in SDLC is characterized by its focus on risk assessment and iterative development, making it suitable for complex projects.
