Consider a scenario where a company wants to migrate its monolithic application to microservices to increase scalability. What might be some challenges faced during this transition?
- Tighter integration
- Enhanced scalability
- Data consistency
- Increased development speed
Transitioning from a monolithic application to microservices can indeed lead to challenges such as tighter integration. In a microservices architecture, services are decoupled, which can make integrating them more complex compared to a monolithic system. This challenge is essential to understand for a successful transition.
Why might Decision Table Testing be utilized in Black Box Testing scenarios?
- It identifies code vulnerabilities
- It helps analyze system architecture
- It handles complex combinations of conditions
- It's mainly used for performance testing
Decision Table Testing is used in Black Box Testing to handle complex combinations of conditions and their corresponding actions. It helps ensure comprehensive test coverage when multiple inputs and their combinations need to be considered.
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 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.
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.
The process of adjusting the contrast or brightness of an image is termed as _______ in image processing.
- Segmentation
- Normalization
- Histogram Equalization
- Enhancement
In image processing, adjusting the contrast or brightness of an image is termed as "Enhancement." Image enhancement techniques are used to improve the visual quality of an image by enhancing specific features such as brightness and contrast.
