Explanation: Adaptive maintenance changes software so it continues to work in a changed operating environment, such as a new operating system…

• A. Error corrections
• B. Enhancements of capabilities
• C. Deletion of obsolete capabilities
• D. All of the mentioned

Explanation: Maintenance covers more than repairing errors: it can add or improve capabilities and remove obsolete features as the system evolves.

• A. hardware and software approach
• B. management and users approach
• C. person and systems approach

Explanation: The standard maintenance classification has four categories: corrective, adaptive, perfective, and preventive.

• A. True
• B. False

Explanation: A sociotechnical system is shaped by both technical components and its human organization, so structure, management practices, and…

• A. True
• B. False

Explanation: Sociotechnical systems include people and organizations, whose actions cannot be predicted as precisely as the behavior of purely…

• A. only software reliability
• B. only hardware reliability
• C. hardware and software reliability
• D. hardware, software and operator reliability

Explanation: Overall reliability in a sociotechnical system depends on the hardware, software, and human operators, because failure in any one of these…

• A. two
• B. three
• C. four
• D. five

Explanation: Large and complex sociotechnical systems commonly pass through three overlapping lifetime stages: procurement or development, operation…

• A. Complex System
• B. Technical computer-based system
• C. Sociotechnical System
• D. Both Complex and Sociotechnical System

Explanation: A police command-and-control system combines people, procedures, technical components, and an operating environment, making it…

• A. True
• B. False

Explanation: Re-engineering reuses and restructures an existing system, so it commonly costs less than developing equivalent software from the…

• A. Build & FIX Model & Waterfall Model
• B. Linear Model & RAD Model
• C. Linear Model & Prototyping Model
• D. Waterfall Model & RAD Model

Explanation: The incremental model combines the systematic structure of the linear model with the feedback and refinement associated with prototyping.

• A. True
• B. False

Explanation: Reverse engineering generally examines an existing system to recover its design, requirements, or structure, and is normally an early…

• A. Type of software to be maintained
• B. Development processes used
• C. Skills and experience of the people involved
• D. All of the mentioned

Explanation: Software evolution processes vary with the type of software, the development process that produced it, and the skills and experience of…

• A. Victor Bisili
• B. Berry Boehm
• C. Bev Littlewood
• D. Roger Pressman

Explanation: Barry Boehm introduced the spiral model in 1986 as a risk-driven alternative to purely sequential development.

• A. Forward engineering
• B. Reverse Engineering
• C. Reengineering
• D. Reverse Engineering and Reengineering

Explanation: Legacy-system evolution commonly uses reverse engineering to understand the existing system and re-engineering to transform it into an…

• A. people
• B. software
• C. hardware
• D. all of the mentioned

Explanation: A sociotechnical system includes the technical elements, such as software and hardware, together with the people and organizational…

• A. diagonal, angular
• B. radial, perpendicular
• C. radial, angular
• D. diagonal, perpendicular

Explanation: The spiral model uses radial and angular dimensions: the radial dimension represents cumulative cost or progress, while the angular…

• A. Evolutionary development usually has two flavors; exploratory development, and throw-away prototyping
• B. Very large projects are usually done using evolutionary development based approach
• C. It facilitates easy project management, through the high volume of documentation it generates
• D. Sometimes the construction of a throw-away prototype is not followed by a re- implementation of the software system using a more structured approach

Explanation: Evolutionary development commonly includes exploratory development and throw-away prototyping.

• A. Forward engineering
• B. Reverse Engineering
• C. Reengineering
• D. Reverse Engineering and Reengineering

Explanation: Reengineering improves an existing system through activities such as program modularization and source-code translation.
