______ maintenance involves making functional enhancements to the software without disturbing its existing functionalities.
- Corrective
- Adaptive
- Perfective
- Preventive
Perfective maintenance involves making functional enhancements to the software without disturbing its existing functionalities. It aims to improve the software by adding new features or enhancing existing ones.
Which phase of the SDLC comes after the implementation and maintenance of the system?
- Requirements Analysis
- Testing
- Implementation
- Maintenance
The maintenance phase of the SDLC comes after the implementation phase. During maintenance, the software system is updated, improved, and adapted to changing needs and requirements.
Which factor is critical in determining the cost of software maintenance?
- Software development methodology
- Software architecture
- Size and complexity of the software
- Team communication skills
The size and complexity of the software are critical factors in determining the cost of software maintenance. Larger and more complex software systems typically require more effort and resources to maintain.
What is the primary focus of integration testing in the software development process?
- Identifying individual module defects
- Testing the entire system functionality
- Testing data communication between modules
- Validating user interface design
Integration testing primarily focuses on testing the interactions and data communication between different software modules. It ensures that these modules work together as expected when integrated into the system.
In Quality Assurance, how does the testing phase vary between the Agile and Waterfall models?
- Testing is more comprehensive in Agile
- Testing is more sequential in Agile
- Testing is only done in Waterfall
- Testing is shorter in Agile
In the Waterfall model, testing typically occurs at the end of the development process, making it more sequential. In contrast, Agile incorporates testing throughout the development cycle, ensuring more continuous and iterative testing to catch issues early.
What is the significance of including SQA processes throughout the software development life cycle?
- It adds unnecessary overhead to the process
- It reduces the project's budget
- It ensures that quality is maintained at every phase
- It hampers collaboration among team members
Including SQA processes throughout the software development life cycle is significant because it ensures that quality is maintained at every phase. It helps prevent defects and issues early in the process, saving time and resources in the long run and ultimately improving the final product.
Prototyping can be particularly useful in Agile development when the customer is unsure about the _______ of the system.
- Cost
- Deadline
- Functionality
- Scope
Prototyping is especially valuable in Agile development when the customer is uncertain about the "Functionality" of the system. It allows customers to see and interact with a partial system, making it easier to refine and clarify requirements as the project progresses.
What does the reliability quality attribute signify in the context of software?
- Speed of the software
- Security of the software
- Trustworthiness and consistency of the software
- Adaptability of the software
Reliability, in the context of software, signifies the trustworthiness and consistency of the software. A reliable software system performs its functions consistently and without unexpected failures, providing a dependable user experience.
In a context where a software system is expected to store and manage highly sensitive user data, how would the security attribute be defined and assured throughout the development process?
- Security is not necessary when dealing with sensitive data
- Security should be a one-time implementation
- Security must be a continuous concern throughout development
- Security is the sole responsibility of users
In this context, security must be a continuous concern throughout the development process. Sensitive user data requires robust security measures, including encryption, access controls, and vulnerability assessments. Security must be implemented from the project's start and maintained as threats evolve.
What role does Version Control play in the context of Software Configuration Management?
- It restricts access to software components
- It helps manage different versions of software artifacts
- It enforces project deadlines
- It ensures that code is error-free
Version Control in SCM plays a crucial role in managing different versions of software artifacts. It enables teams to track changes, roll back to previous versions, and collaborate effectively on code and documentation, ensuring traceability and version history.
