Envision a situation where a team is developing an e-commerce application that requires various services like payment, user authentication, and product management. Discuss the suitability of microservices architecture.
- Microservices are not suitable
- Microservices are suitable
- Microservices are suitable only for small applications
- Microservices are suitable only for large applications
For an e-commerce application that requires multiple services like payment, user authentication, and product management, a microservices architecture is suitable. Microservices allow each component to be developed and scaled independently, making it easier to manage and maintain different parts of the application.
In the context of software engineering, ______ ensures that the product is built according to the specified requirements, while ______ ensures that the product meets the user's needs.
- Verification, validation
- Maintenance, testing
- Documentation, coding
- Design, planning
In software engineering, verification ensures that the product is built according to the specified requirements, making it "right." Validation ensures that the product meets the user's needs and is "built right." These two processes work together to ensure the software's quality and alignment with both requirements and user expectations.
Envision a situation where a team using the Big Bang model reaches a critical point in development and realizes a major flaw in the current build. Discuss the potential steps the team might take and the challenges posed by the Big Bang model in resolving this issue.
- Steps: Detailed documentation, Challenges: Increased cost
- Steps: Extensive planning, Challenges: Slow response
- Steps: Rapid fixes, Challenges: Reduced quality
- Steps: Start from scratch, Challenges: Wasted effort
In a Big Bang model, if a major flaw is discovered, the team might have to start from scratch, which can result in wasted effort. The model's lack of incremental development and detailed planning can make it challenging to adapt and rectify critical issues efficiently.
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.
How does automation in software testing enhance the ability to detect errors and improve overall software quality?
- Automation eliminates all errors
- Automation speeds up testing without error detection
- Automation allows for repetitive and systematic testing
- Automation increases the cost of testing
Automation in software testing allows for repetitive and systematic testing, ensuring that the same tests are executed consistently. This not only detects errors more efficiently but also improves software quality by reducing human errors and providing faster feedback.
