Which of the following is a legitimate use of reverse engineering in software development?
- Unauthorized software duplication
- Understanding how a third-party application works
- Software piracy
- Stealing proprietary code
A legitimate use of reverse engineering in software development is to understand how a third-party application works. This can be important for interoperability, integration, or troubleshooting issues with software from external sources.
Which principle of user interface design implies that the interface should be kept simple?
- Fitts's Law
- Hick's Law
- Occam's Razor
- Jakob's Law
Occam's Razor is a principle in user interface design that suggests keeping the interface simple. It advocates simplicity and minimalism in design, emphasizing that unnecessary elements or complexity should be avoided to enhance user experience.
What is the primary focus of the Software Evolution Models?
- Initial development
- Adapting to changes
- Testing
- Maintenance
The primary focus of Software Evolution Models is to adapt software systems to changes that occur over time. These changes may include bug fixes, enhancements, and adaptations to new requirements and technologies.
How does Black Box Testing address usability concerns in software development?
- By examining the source code
- By analyzing the algorithmic complexity
- By focusing on internal system interactions
- By evaluating user interfaces and functionality
Black Box Testing assesses software usability by concentrating on the software's external functionality, user interfaces, and how well it meets user needs. It doesn't require access to the source code or internal workings.
_____ is a quality attribute that refers to the software's ability to operate correctly in all its intended environments and scenarios.
- Reliability
- Performance
- Security
- Usability
Reliability is a crucial quality attribute in software engineering. It signifies the software's ability to operate correctly in all its intended environments and scenarios, providing consistent and dependable performance. A reliable software system minimizes the chances of failures or errors.
In a scenario where a software review identifies critical design flaws late in the development process, how should the project team navigate through this challenge to ensure minimal project delay and cost overrun?
- Continue development without addressing the flaws
- Halt the project and start from scratch
- Assess the impact of the flaws, prioritize necessary changes, and implement them efficiently
- Blame the development team for the flaws
When critical design flaws are discovered late in the development process, it is essential to assess the impact of these flaws, prioritize necessary changes, and implement them efficiently to minimize project delay and cost overrun. Starting from scratch or ignoring the flaws can be time-consuming and costly. Blaming the team doesn't solve the issue.
Verification is typically performed by the ______ team, while validation is typically performed by the ______ team.
- Development, Testing
- Testing, Development
- Quality Assurance, Project Management
- Business Analysts, Customers
Verification, in the context of software engineering, is typically performed by the testing team. It involves checking whether the software meets its specified requirements. Validation, on the other hand, is typically performed by the development team, ensuring that the software meets the customer's needs and expectations.
In a scenario where a security audit for a software application is necessary, how might white box testing be utilized to identify potential vulnerabilities in the code?
- By ignoring the code and focusing only on user interface vulnerabilities
- By running penetration tests from an external perspective
- By analyzing the code, identifying weak points, and simulating attacks
- By relying on automated testing tools without code analysis
White box testing, in a security context, involves analyzing the code to identify potential vulnerabilities, such as code injection or security weaknesses, and then simulating attacks to verify their presence.
Which design pattern defines a family of algorithms, encapsulates each one, and makes them interchangeable?
- Singleton Pattern
- Factory Pattern
- Strategy Pattern
- Prototype Pattern
The Strategy design pattern defines a family of algorithms, encapsulates each one, and makes them interchangeable. It allows you to define a set of algorithms, encapsulate them in separate classes, and make them interchangeable at runtime, enabling the client to choose the appropriate algorithm without altering its code. This pattern is especially useful when you want to provide multiple ways to accomplish a task, such as sorting, without changing the client code.
The quality attribute _____ refers to the speed with which the software operates and processes data.
- Reliability
- Performance
- Security
- Usability
Performance is a quality attribute that focuses on the speed and efficiency of a software system. It involves how quickly the software performs tasks and processes data. Good performance ensures that the software is responsive and meets user expectations.
