_____ maps involve creating a visual representation of the interfaces navigation structure.
- Task
- Flow
- Experience
- Wireframe
Flow maps in UI design are used to create a visual representation of the interface's navigation structure. They help designers understand how users move through the interface, the paths they take, and the connections between different screens or elements. Flow maps are essential for designing user-friendly navigation systems.
Envision a situation where an API is expected to handle a large number of requests per second. Discuss how API caching mechanisms might be employed to enhance performance without overburdening the backend systems.
- Use rate limiting
- Implement data partitioning
- Employ Content Delivery Network (CDN)
- Implement caching of frequently accessed data
Caching frequently accessed data can significantly enhance API performance by reducing the load on the backend systems. This approach is especially valuable in high-traffic scenarios, as it serves cached responses to clients, reducing the need to fetch data from the backend repeatedly.
The _____ pattern is used to create a copy of the existing object to enhance performance?
- Singleton
- Prototype
- Decorator
- Bridge
The Prototype design pattern is used to create a copy of an existing object to enhance performance. It is particularly useful when creating new objects is more expensive than copying an existing one, such as in scenarios where complex object initialization is involved.
What considerations must be taken into account when employing Black Box Testing in integration testing scenarios?
- Data-driven testing
- API compatibility
- Code structure analysis
- Unit testing coverage
When using Black Box Testing in integration testing, one must consider API compatibility between different software components. Integration testing focuses on the interactions between components, and ensuring APIs work correctly is crucial.
How does the ISO/IEC 25010 standard classify software quality in terms of characteristics and sub-characteristics?
- It defines 8 characteristics and 25 sub-characteristics
- It defines 6 characteristics and 16 sub-characteristics
- It defines 7 characteristics and 31 sub-characteristics
- It defines 10 characteristics and 42 sub-characteristics
ISO/IEC 25010 classifies software quality into 8 characteristics and 25 sub-characteristics. These characteristics include functionality, reliability, usability, efficiency, maintainability, and others, each with their own set of sub-characteristics that further categorize quality attributes.
One common method of stress testing is to deliberately introduce ______ to observe how the system recovers and maintains stability.
- High traffic
- Low traffic
- Software updates
- Security vulnerabilities
One common method of stress testing involves deliberately introducing high traffic to observe how the system responds under stress. This helps assess the system's ability to maintain stability and recover from stress-induced issues.
In what way does Software Configuration Management facilitate audit and review processes in software development?
- SCM has no relevance to the audit and review process.
- SCM helps maintain the version history but doesn't assist in audits.
- SCM tracks changes and provides an audit trail for accountability.
- SCM only deals with code compilation.
Software Configuration Management facilitates the audit and review processes in software development by tracking changes and providing an audit trail. This allows for accountability and the ability to trace who made changes and when, making audits and reviews more effective.
The principle of _____" implies that all API calls should result in the same outcome regardless of how many times the call is repeated.
- Repetition
- Consistency
- Uniqueness
- Redundancy
The principle of "Consistency" implies that all API calls should result in the same outcome regardless of how many times the call is repeated. It's a fundamental principle in designing reliable and predictable APIs.
What is a critical distinction between software validation and verification?
- Verification is done by the developers, while validation is done by the customers.
- Verification checks if the software conforms to its specifications, while validation checks if it meets the customer's needs.
- Verification is done before coding, while validation is done after coding.
- Verification focuses on the software's performance, while validation focuses on its user interface.
A critical distinction between software verification and validation is that verification checks if the software conforms to its specifications, ensuring that it's built correctly, while validation checks if it meets the customer's needs, ensuring that it's the right software for the intended purpose.
What role does data re-engineering play within the broader scope of software re-engineering?
- Data re-engineering is unrelated to software re-engineering
- Data re-engineering focuses on improving software security
- Data re-engineering involves restructuring and optimizing data storage and management within the software
- Data re-engineering only deals with data backup and recovery
Data re-engineering is a vital aspect of software re-engineering, focusing on the improvement of data storage, data management, and data-related processes to enhance the software's performance and efficiency.
