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 database design technique helps to minimize data redundancy and dependency by organizing fields and tables of a database?
- Data Segmentation
- Data Normalization
- Data Aggregation
- Data Duplication
Data normalization is a database design technique that helps minimize data redundancy and dependency by organizing data into separate tables and eliminating duplicate data. It involves breaking down large tables into smaller, related tables to reduce data anomalies and improve data integrity.
Validation is concerned with ______ testing, while verification deals with ______ testing.
- White-box, Black-box
- Black-box, White-box
- Functional, Structural
- Unit, Integration
Validation primarily focuses on black-box testing, where the internal structure of the software is not considered, but its functionality is validated against user requirements. Verification is associated with white-box testing, where the internal code structure is examined for correctness and adherence to design.
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.
During stress testing, what aspect of a software system is primarily evaluated?
- Usability
- Security
- Reliability
- Performance
Stress testing primarily evaluates the performance aspect of a software system. It aims to determine how the system handles heavy workloads and high stress conditions, including response times and resource utilization.
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.
