software testing MCQ, Which SDLC model is suitable for large-scale projects with high-risk factors? A YouTube video on the Software Development Life Cycle (SDLC) would typically cover the various phases and activities involved in developing a software application. The video might explain the following stages:

Requirements Gathering: In this phase, the requirements of the software application are collected from stakeholders, including users, clients, and business analysts. The video may discuss techniques such as interviews, surveys, and workshops to gather and document the requirements effectively.

System Analysis: During this phase, the gathered requirements are analyzed, and a detailed system analysis is performed. This includes studying the current system (if any), identifying areas of improvement, and defining the desired system's features, functions, and architecture.

System Design: The video may explain how the system design phase involves creating a blueprint for the software application. It covers architectural design, database design, interface design, and other technical aspects. The design decisions and specifications are documented to guide the development process.

Coding and Implementation: The video would discuss the actual coding or programming phase, where developers write the source code based on the design specifications. It may explain various programming languages, frameworks, and tools used in the development process. Best practices and coding standards might also be highlighted.

Testing and Quality Assurance: This phase focuses on ensuring the quality and reliability of the software application. The video may discuss different types of testing, including unit testing, integration testing, system testing, and acceptance testing. It may cover various testing techniques, test automation, and tools used to validate the software against the specified requirements.

Deployment and Release: The video may explain the steps involved in deploying the developed software application to the production environment. It may discuss release management, installation, configuration, and any required data migration. The video could also highlight the importance of version control and proper documentation during deployment.

Maintenance and Support: The video may discuss the ongoing maintenance and support activities after the software is released. It may cover bug fixes, performance enhancements, feature upgrades, and user support. The importance of customer feedback and continuous improvement might also be emphasized.

Software Life Cycle Models: The video might provide an overview of different SDLC models such as Waterfall, Agile, Spiral, or iterative models. It could explain the advantages, disadvantages, and suitable use cases for each model.
