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.
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.
In software testing, what is the main objective of performing defect testing?
- To find and fix defects in the code
- To validate the requirements
- To verify the usability of the software
- To assess the performance of the software
The primary objective of defect testing is to find and identify defects or bugs in the software code so that they can be fixed before the software is released.
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.
Which design principle aims to manage dependencies between modules effectively?
- Cohesion
- Coupling
- Abstraction
- Inheritance
The design principle that aims to manage dependencies between modules effectively is "Coupling." It refers to the degree of interconnection between modules in a software system. Reducing coupling helps make the system more maintainable and flexible.
The main focus of ______ maintenance is to manage the changes in the software operating environment.
- Corrective
- Adaptive
- Perfective
- Preventive
Adaptive maintenance focuses on managing changes in the software operating environment, such as adapting it to new hardware or software platforms. It ensures the software remains compatible with evolving technology.
