How does the Maintenance phase in the SDLC ensure the longevity and relevance of a software product?
- It adapts to changing needs
- It focuses on cost reduction
- It handles bug fixes
- It updates the user manual
The Maintenance phase in the SDLC ensures the longevity and relevance of a software product by adapting it to changing needs, adding new features, and addressing issues. It's not just about reducing costs or updating documentation; it's about keeping the software up-to-date and valuable to users over time.
Which SDLC model emphasizes iterative development and the necessity of maintaining a flexible approach to changes in the project?
- Agile Model
- Incremental Model
- V-Model
- Waterfall Model
The Agile Model emphasizes iterative development and flexibility. It involves short development cycles, frequent feedback, and adaptability to changes. This approach is well-suited for projects with evolving requirements.
In large enterprises, the selection of Requirement Management Tools should consider aspects such as ______ and ______.
- Color, Complexity
- Coordination, Control
- Cost, Compatibility
- Creativity, Change
In large enterprises, the selection of Requirement Management Tools should consider aspects such as cost and compatibility. Cost is a significant factor, as large enterprises need cost-effective solutions, and compatibility is essential for integrating the tool into existing systems.
Which technique involves visualizing and detailing the system's functionalities in the form of user actions and system responses during requirement documentation?
- Data Modeling
- Entity-Relationship Diagrams
- Network Diagrams
- Use Case Modeling
Use Case Modeling is a technique that visualizes the system's functionalities by describing user actions and system responses. It helps in understanding how the system will interact with users and other components.
Which aspect of database design ensures that there is minimal redundancy and dependency by organizing fields and tables of a database?
- Data Serialization
- Data Validation
- Database Fragmentation
- Database Normalization
Database Normalization is the process of organizing data in a database to minimize redundancy and dependency, which leads to a more efficient and reliable database structure.
One of the limitations of traditional SDLC is that testing is often relegated to the _____ phase, which can lead to delays.
- Development
- Planning
- Requirements
- Testing
One of the limitations of traditional SDLC is that testing is often relegated to the Development phase. This means that testing occurs late in the cycle, which can lead to delays and increased costs due to the identification and rectification of defects late in the process. It is more effective to incorporate testing earlier in the process to catch issues sooner.
What is the main purpose of using a testing framework like JUnit or TestNG?
- To automate unit and integration tests
- To create user interfaces
- To manage software development projects
- To write software documentation
JUnit and TestNG are testing frameworks that automate the execution of unit and integration tests, making it easier to validate code and improve software quality.
Which limitation of SDLC is highlighted by the need for extensive documentation in every phase?
- Excessive emphasis on user involvement.
- Lack of flexibility and adaptability.
- Lack of structure in SDLC.
- Potential for scope creep.
The extensive documentation requirement in traditional SDLC models underscores the limitation of rigidity and lack of adaptability to changing project needs, making it challenging to manage evolving requirements.
How do tools like Selenium WebDriver facilitate automated testing in software development?
- They automate the entire software development process.
- They only work with Java applications.
- They provide a framework for automating web application testing.
- They require manual test case creation.
Selenium WebDriver is a tool that provides a framework for automating web application testing. It allows testers to write test scripts in various programming languages and automate the testing of web applications across different browsers.
The ________ in a bug tracking system provides detailed information about a bug, including its status, priority, and description.
- Bug report
- Bug repository
- Bug tracker
- Bug triage
In a bug tracking system, the bug tracker is the component that provides detailed information about a bug. It includes its status, priority, description, and other relevant details, allowing for effective management and resolution of bugs.
