The _______ phase of the SDLC involves validating the requirements to ensure they align with the project's objectives.
- Design
- Planning
- Requirements
- Testing
The Requirements phase of the SDLC involves validating the requirements to ensure they align with the project's objectives. This phase is crucial for establishing a clear project scope and ensuring that the requirements are realistic and achievable.
During _____ testing, a software application is tested with a specific expected load to evaluate its performance.
- Acceptance
- Alpha
- Beta
- Stress
During "Stress" testing, a software application is tested under a specific expected load to assess its performance under extreme conditions and to identify its breaking point.
How does the V-Model in SDLC ensure that the processes in the development and testing phases correspond with each other?
- By conducting testing before the development phase to identify issues earlier
- By defining corresponding development and testing phases in a sequential and parallel manner
- By outsourcing the testing phase to a different team
- By overlapping development and testing phases for quicker results
The V-Model ensures that development and testing processes correspond by defining corresponding development and testing phases that run in a sequential and parallel manner. It emphasizes testing requirements based on corresponding development phases, improving alignment and effectiveness.
The _______ model of SDLC combines the features of both the waterfall model and the prototype model.
- Agile
- Spiral
- V-Model
- Waterfall-Prototype
The Waterfall-Prototype model combines characteristics of the traditional Waterfall model and the iterative Prototype model. It allows for early feedback like prototyping while maintaining a structured approach like Waterfall.
The _____ phase of the SDLC involves rigorous testing to ensure that the software meets all specified requirements and is ready for production.
- Development
- Maintenance
- Planning
- Testing
The Testing phase of the SDLC is where rigorous testing is conducted to validate that the software meets specified requirements and is ready for production.
What challenges might a software development team face when using a throwaway prototyping model?
- It eliminates all bugs.
- It ensures low cost.
- It provides a systematic approach.
- It speeds up development.
The throwaway prototyping model involves creating a quick, disposable prototype to understand requirements. Challenges include the potential for wasted effort if the prototype isn't reused and a risk of misunderstanding that the prototype is the final product.
How does requirement validation contribute to the overall success of a software development project?
- Eliminates the Need for Testing Phase
- Enhances Software Quality
- Lowers Development Costs
- Reduces Project Timeline
Requirement validation ensures that the project's requirements are clear and feasible. This leads to a higher-quality product, reduced rework, and ultimately contributes to the overall success of the project.
For creating vector-based designs and interactive click-through prototypes, designers might prefer using _____.
- Adobe Illustrator
- Adobe Photoshop
- Balsamiq Mockups
- Microsoft Word
Designers often prefer using vector-based tools like Adobe Illustrator for creating vector-based designs and interactive click-through prototypes. These tools offer more precise control over design elements, making them suitable for such tasks.
How does Test-Driven Development (TDD) contribute to cleaner code and better software design?
- It avoids code reviews.
- It emphasizes refactoring.
- It encourages minimal testing.
- It focuses on testing after coding.
Test-Driven Development (TDD) contributes to cleaner code and better software design by emphasizing refactoring. Refactoring ensures that code remains clean, maintainable, and optimized as it evolves, improving software quality.
In the context of monitoring, _____ refers to automatically adjusting resources based on the application's demand.
- Auto-scaling
- Load balancing
- Performance optimization
- Resource allocation
Auto-scaling is a monitoring and management practice that automatically adjusts resources (such as server capacity) based on an application's demand. It ensures that the application can handle varying workloads efficiently.
