Imagine you are tasked with creating a prototype for a mobile application. The client is unsure of the requirements and expects to refine them as the project progresses. Which prototyping model would be most suitable in this scenario?
- Agile Model
- Evolutionary Prototyping
- Throwaway/Rapid Prototyping
- Waterfall Model
In a scenario where requirements are expected to change and evolve, a throwaway/rapid prototyping model is suitable. It allows quick iterations and refining of requirements.
A software development team is transitioning from a procedural programming paradigm to an object-oriented one. What challenges might they face in terms of coding practices and design principles?
- Difficulty in coding reuse
- Easier maintenance
- No challenges
- Simplified testing
Transitioning from procedural to object-oriented programming may pose challenges related to coding practices and design principles. Procedural code is often less reusable, making it challenging to adapt to the OOP paradigm, where reusability is a core principle. This transition also requires understanding and implementation of encapsulation, inheritance, and polymorphism.
Agile methodologies prioritize ______ over processes and tools, addressing a common limitation of traditional SDLC.
- Comprehensive processes
- Documentation
- Formal contracts
- Individuals and interactions
Agile methodologies prioritize individuals and interactions over processes and tools. This emphasis helps address a common limitation of traditional SDLC, where rigid processes and excessive documentation can hinder flexibility and collaboration.
What strategies can be employed to ensure that the gathered requirements align with the stakeholders' needs and expectations?
- Avoid involving stakeholders until project completion
- Conduct regular status meetings
- Engage stakeholders and perform thorough analysis
- Implement strict change control procedures
Engaging stakeholders and conducting thorough analysis are key strategies to ensure that requirements align with their needs and expectations. Regular communication and collaboration help identify and address any discrepancies or changes early in the project lifecycle.
What challenges might an organization face when implementing a Blue-Green deployment strategy at scale?
- Complex infrastructure management
- Increased resource utilization
- Reduced testing capabilities
- Slower time-to-market
Implementing Blue-Green deployment at scale can lead to challenges such as complex infrastructure management, maintaining separate environments, and ensuring data consistency between them. This can impact testing capabilities and require careful planning.
________ testing is a type of performance testing that evaluates how a system behaves under an increasing load, often beyond its specified requirements.
- Compatibility
- Regression
- Stress
- Usability
Stress testing is a form of performance testing that assesses how a system behaves under increasing loads or stress. It often involves pushing the system beyond its specified requirements to identify performance bottlenecks and issues under heavy usage.
A company wants to deploy a critical update to its software without causing any downtime. Which deployment strategy would be most suitable?
- Blue-Green Deployment
- Canary Deployment
- Parallel Deployment
- Rolling Deployment
Blue-Green Deployment is suitable for deploying critical updates without downtime. It involves creating an identical environment and switching traffic once the update is validated, ensuring minimal disruption to users.
A company notices that their application slows down during peak usage times. Which monitoring and logging metrics would be most beneficial to diagnose the issue?
- Employee satisfaction
- Marketing campaign success
- Memory usage, CPU utilization
- Number of bug fixes
Monitoring and logging metrics like memory usage and CPU utilization are crucial to diagnose performance issues during peak usage. These metrics help identify resource bottlenecks causing slowdowns.
What considerations are typically evaluated during the Feasibility Study in the initial phases of the SDLC?
- Hardware requirements
- Market analysis
- Software testing
- Technical feasibility
During the Feasibility Study in the initial phases of SDLC, technical feasibility assesses whether the proposed project is technically possible, considering hardware, software, and other technical requirements. This evaluation helps decide whether to proceed with the project. Other aspects like market analysis, hardware, and software testing are considered later in the SDLC.
The process of identifying bottlenecks, or slow-performing areas in a software application, is known as _____ testing.
- Black-box
- Performance
- Usability
- White-box
Performance testing is the process of identifying bottlenecks or slow-performing areas in a software application, ensuring it meets performance requirements.
