Which testing approach involves testing the data communication amongst different software modules?
- Unit Testing
- System Testing
- Regression Testing
- Interoperability Testing
Interoperability testing specifically involves testing the data communication and interactions between different software modules to ensure they work together seamlessly.
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.
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 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.
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.
How does denormalization in databases affect data retrieval times?
- It slows down data retrieval
- It has no impact on data retrieval
- It speeds up data retrieval
- It causes data corruption
Denormalization in databases can speed up data retrieval times because it reduces the need for complex joins and queries. However, it can lead to increased storage requirements and potential data inconsistencies, so it should be used judiciously.
What is a key benefit of software re-engineering in relation to system performance?
- Improved user interface
- Enhanced security
- Increased speed and efficiency
- Better hardware compatibility
Software re-engineering can lead to increased speed and efficiency. By optimizing and modernizing software, it can run faster and more efficiently, improving system performance. This can involve optimizing code, upgrading data structures, and other enhancements.
How does the Maintainability Index (MI) provide insights into the future perspectives of a software product?
- MI assesses project budget
- MI measures code complexity and maintainability
- MI evaluates user satisfaction
- MI predicts market demand
The Maintainability Index (MI) provides insights into the future perspectives of a software product by measuring code complexity and maintainability. A higher MI score indicates that the code is easier to maintain, reducing the cost and effort required for future enhancements or bug fixes.
During stress testing, its vital to monitor system parameters like CPU usage, memory usage, and ______ to evaluate performance under stress.
- Network latency
- Software licensing
- User satisfaction
- Battery life
During stress testing, it's important to monitor system parameters like CPU usage, memory usage, and network latency. This allows for a comprehensive evaluation of the system's performance under stress, including how it handles network-related challenges.
In GraphQL, the _____ defines the operations that can be performed to access the data.
- Server
- Resolver
- Schema
- Query
In GraphQL, the "Schema" defines the operations that can be performed to access the data. The schema specifies the types of data that can be queried and the structure of those queries.
Which form of integration testing focuses on verifying the integration between different systems or subsystems?
- Top-Down Integration Testing
- Bottom-Up Integration Testing
- Unit Integration Testing
- Incremental Integration Testing
Top-Down Integration Testing focuses on verifying the integration between different systems or subsystems within a software application. It starts with testing the highest-level modules first and progressively integrates lower-level modules.
Fill in the blank: "The _____ attribute relates to the ease with which a software product can be transferred from one hardware or software environment to another."
- Scalability
- Reliability
- Portability
- Usability
Portability is the attribute that concerns the ease of transferring a software product from one environment to another, be it different hardware, software, or operating systems. This is important for making software versatile and adaptable.
