Quality Assurance in Agile involves regular _______ to discuss any issues or changes needed in the ongoing project.
- Documentation reviews
- Risk assessments
- Status meetings
- Testing phases
Quality Assurance in Agile involves regular status meetings to discuss any issues or changes needed in the ongoing project. These meetings help ensure that the project aligns with its goals and that quality is maintained.
A _____ architecture style has a single codebase and is often easier to deploy.
- Monolithic
- Microservices
- Client-Server
- Peer-to-Peer
The Monolithic architecture style has a single codebase, and it is often easier to deploy as the entire application is packaged as a single unit. This simplicity can make deployment and maintenance more straightforward.
In a scenario where a software system is expected to experience frequent changes due to market dynamics, discuss how software evolution models can be strategically applied to manage these changes effectively.
- Utilize iterative models
- Implement a traditional waterfall model
- Employ agile methodologies
- Choose a fixed model
In a dynamic market environment, where frequent changes are expected, it is essential to apply software evolution models that are adaptable. Iterative models, such as Agile methodologies, allow for incremental and flexible development, making them a strategic choice to manage changes effectively. They enable continuous adaptation to evolving requirements and market dynamics.
The process of reverse engineering can be crucial in identifying and mitigating software _____ that may be exploited by malicious entities.
- Code Complexity
- Security Flaws
- Hardware Dependencies
- Documentation Gaps
Reverse engineering plays a critical role in identifying and mitigating software security flaws. By discovering vulnerabilities, organizations can address them before malicious entities exploit these weaknesses, ultimately enhancing the security of their software systems.
If a cloud-based application experiences irregular spikes in user traffic, how might stress testing be strategically employed to prepare the system for unexpected loads and ensure consistent performance?
- Regularly perform stress tests without any consideration for spikes
- Stress test only during scheduled maintenance
- Use automated tools to simulate traffic spikes and observe system behavior
- Ignore spikes in user traffic as they are unpredictable
To prepare a cloud-based application for irregular spikes in user traffic, stress testing should be strategically employed. Automated tools can simulate these spikes to observe how the system behaves under such conditions. This helps identify any performance bottlenecks and ensure consistent performance.
Suppose a newly developed e-commerce platform is expected to handle thousands of transactions per minute during a sale. How would stress testing be utilized to ensure the platform can manage this load without critical failures?
- Simulate peak loads and monitor system performance
- Run regular functional tests
- Skip stress testing and rely on monitoring
- Perform stress testing only after critical failures occur
Stress testing in this scenario involves simulating peak loads, which means subjecting the system to the expected high transaction volumes. By monitoring system performance under these loads, we can identify bottlenecks and ensure the platform can handle the load without critical failures.
Which principle suggests that derived classes must be substitutable for their base classes?
- Encapsulation
- Abstraction
- Inheritance
- Polymorphism
The principle suggesting that derived classes must be substitutable for their base classes is "Polymorphism." It allows objects of derived classes to be used where objects of the base class are expected, enabling flexibility and extensibility in software design.
A ______ audit is performed to ensure that all contractual agreements have been fulfilled and the product meets the specified requirements.
- Technical
- Quality
- Compliance
- Code
A compliance audit is performed to ensure that all contractual agreements, legal requirements, and specified standards have been fulfilled. In the context of software engineering, this type of audit is crucial to confirm that the product adheres to all requirements and agreements.
The main objective of ______ maintenance is to foresee and solve problems and issues before they occur.
- Corrective
- Adaptive
- Preventive
- Perfective
Preventive maintenance focuses on anticipating and preventing issues before they occur. It involves tasks such as code reviews, proactive bug-fixing, and performance optimization to maintain the system's reliability.
When is regression testing typically performed within the software development process?
- At the beginning of the development phase
- After the software has been released to users
- During the initial testing phase
- After code changes are made, and before a new release or update
Regression testing is typically performed after code changes are made and before a new release or update of the software. It ensures that existing functionality remains intact after modifications.
