In the context of cybersecurity, reverse engineering can be employed to analyze ______ and devise defensive strategies.
- Malware
- Network Traffic
- Software Vulnerabilities
- Encryption Algorithms
Reverse engineering in cybersecurity is often used to analyze software vulnerabilities. By dissecting software, security professionals can uncover weaknesses and devise strategies to defend against potential exploits. This process is essential for maintaining robust cybersecurity.
What role do foreign keys play in relational database design?
- They define primary keys
- They store data values
- They establish relationships between tables
- They control access to the database
Foreign keys in relational database design establish relationships between tables. They link data in one table to data in another, enabling the creation of relationships and ensuring referential integrity.
A _______ is a white box testing technique that involves executing all possible branches in the code.
- Boundary value analysis
- Code review
- Branch coverage
- Black box testing
Branch coverage is a white box testing technique that involves executing all possible branches in the code. It aims to ensure that every possible branch in the code is tested, helping to identify potential issues related to control flow and logic.
How does software re-engineering facilitate the accommodation of new technologies and features?
- By increasing maintenance costs
- By slowing down the development process
- By providing a clean and modular architecture
- By eliminating the need for updates
Software re-engineering typically involves refactoring the existing code to create a clean and modular architecture. This makes it easier to accommodate new technologies and features, as the codebase becomes more adaptable and maintainable.
What is the relevance of creating stubs and drivers during the integration testing process?
- Stubs and drivers are not used in integration testing
- They simulate components not available for testing
- They replace the need for other testing phases
- Stubs and drivers are only used for unit testing
Stubs and drivers are essential in integration testing as they simulate components that are not yet available for testing. By creating these placeholders, developers can validate the interactions between the tested components and the missing or incomplete ones.
Fill in the blank: "_____ refers to the ability of software to be understood, learned, used, and attractive to the user when used under specified conditions."
- Scalability
- Reliability
- Portability
- Usability
Usability is all about the user experience. It refers to how easy it is for users to understand, learn, and use the software effectively under specific conditions. High usability is crucial for user satisfaction and productivity.
During white box testing, the tester must have knowledge of the ______ to construct test cases and identify issues.
- System's users
- External interfaces
- Internal code structure
- Project timeline
In white box testing, the tester needs to have knowledge of the internal code structure to construct test cases and identify issues. This type of testing involves examining the internal logic, structure, and flow of the software code. Understanding the code is essential for effective white box testing.
The _______ model is an approach to software evolution that focuses on incremental development and operational prototyping.
- Waterfall
- Spiral
- Evolutionary
- Agile
The Spiral model is an approach to software evolution that emphasizes incremental development and operational prototyping. This model divides the project into cycles or "spirals," with each spiral incorporating user feedback and refined prototypes. This iterative approach allows for continuous improvements and risk management throughout the software development process.
What is the primary aim of software verification in the software development life cycle?
- Identifying and fixing defects in the software
- Ensuring that the software meets the customer's requirements
- Testing the software in a real-world environment
- Validating user interface design
The primary aim of software verification is to identify and fix defects in the software. It involves activities like code reviews and inspections to ensure the software aligns with its specifications and design.
For machine learning model deployment in a production environment, which tool or language is often integrated due to its performance and scalability?
- Python
- R
- Java
- Kubernetes
Java is often integrated into production environments for machine learning model deployment due to its performance and scalability. Java is known for its speed, robustness, and suitability for large-scale applications. It is commonly used to build APIs and services for serving machine learning models in real-time production systems. Python and R are often used in model development, but Java is favored for deployment. Kubernetes is an orchestration tool.
