The _____ SOLID principle states that classes should be open for extension but closed for modification.
- Dependency
- Liskov
- Open-Closed
- Single
The Open-Closed SOLID principle states that classes should be open for extension but closed for modification. It promotes software design that allows for new functionality to be added without altering existing code.
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.
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.
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.
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.
What is the primary goal of the requirement gathering process in software development?
- Conduct product testing
- Define the color scheme
- Identify potential team members
- Understand and document the needs of stakeholders
The primary goal of the requirement gathering process is to understand and document the needs and expectations of stakeholders, which helps in creating a software system that meets their requirements.
In the context of database design, what does the term 'Normalization' refer to?
- Complexifying the database
- Eliminating data from the database
- Optimizing database performance
- Simplifying the database
In the context of database design, 'Normalization' refers to simplifying the database structure by organizing data into smaller, related tables to improve data integrity and minimize redundancy.
To ensure that all stakeholders have a clear and common understanding of the system requirements, they are usually __________ in a structured document.
- Modeled
- Reviewed
- Validated
- Written
To ensure a clear and common understanding, system requirements are typically written in a structured document. This documentation serves as a reference for all stakeholders involved in the project.
How do monitoring and logging practices need to evolve when transitioning from a monolithic to a microservices architecture?
- They are not needed in microservices.
- They become less important.
- They become more complex and distributed.
- They remain the same.
Transitioning from monolithic to microservices requires more complex and distributed monitoring and logging. Microservices introduce new challenges, such as service discovery and container orchestration.
Imagine a software development team is tasked with maintaining a legacy application. Which software maintenance model would be most appropriate if the application requires frequent updates and enhancements?
- Adaptive Maintenance
- Corrective Maintenance
- Perfective Maintenance
- Preventive Maintenance
Adaptive maintenance is suitable for legacy applications requiring frequent updates and enhancements. It ensures the system can adapt to evolving requirements while maintaining stability.
What is the primary goal of Software Architecture Design in the SDLC?
- Code implementation efficiency
- Enhancing user experience
- Ensuring security and scalability
- Writing documentation
Software Architecture Design in SDLC primarily aims to ensure the security and scalability of the system. It involves making architectural decisions to address these concerns and guide the development process.
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.
