Software Engineering is part of Computer Science and holds 1,969 questions with answers, free to read and with no account needed.
Questions from this area appear in PPSC, FPSC, NTS, KPPSC and SPSC papers. Each guide explains how that paper is built and which subjects carry it.
Attempt each question before revealing the answer, and keep a note of the ones you get wrong — those are the topics worth reading about properly. If an answer looks wrong, there is a link to report it on every question.
Answer: B. inverse relation
Reliability and failure intensity share an inverse mathematical relationship in software engineering. As the frequency of software failures increases, overall system reliability decreases proportionally. Higher failure i...
Answer: C. Redundancy
Fault-tolerant engineering techniques are universally dependent on redundancy. Redundancy involves duplicating critical hardware or software components. Systems use backup modules to take over seamlessly if primary parts...
Answer: D. MTBF
Failures in time measures expected failures per one billion operating hours as an alternative metric. Mean time between failures calculates the average operational time elapsed between successive system breakdowns. Both...
Answer: D. Fail Safe
A fail-safe system maintains overall data integrity even when forced into a temporary halt state. Safety mechanisms prevent catastrophic damage by transitioning the system into a secure predetermined condition. Accepting...
Answer: B. Mean time to failure
MTTF stands for Mean Time To Failure which quantifies the average operational duration before a system fails. This reliability metric helps engineers estimate how long hardware or software will run without crashing. Calc...
Answer: C. Eliminate the use of project planning and testing
Agile processes deliver software quickly by reducing overhead without eliminating planning. Project planning and testing remain critical activities essential for maintaining high quality. Agility streamlines workflows bu...
Answer: C. five
The Capability Maturity Model explicitly defines five distinct levels of process maturity. These levels provide a roadmap for organizations improving their software engineering processes. Starting from Initial, organizat...
Answer: B. Portability
Portability is a characteristic of the software product rather than the process. It measures how easily software runs on different hardware or operating systems. Product qualities describe the final artifact while proces...
Answer: C. Iteration occurs within activities
Agile development interleaves specification, design, implementation, and testing within short iterative cycles. Plan-driven methodologies enforce sequential phases where each activity must finish before the next begins....
Answer: D. All of the mentioned
Evolutionary models are iterative and incremental. The WINWIN Spiral, Incremental, and Concurrent models all fall under this category.
Answer: B. Prototyping & Spiral
Prototyping and Spiral models are specifically designed to accommodate evolving and emergent requirements. Neither model demands a complete and fixed definition of user requirements at the project start. Iterative feedba...
Answer: D. User Reviews
User reviews are core framework activities rather than umbrella activities that span the entire development lifecycle. Umbrella activities such as risk management and measurement apply continuously across all five proces...
Answer: D. RAD & Prototyping
RAD and Prototyping both rely on continuous user feedback and active involvement. Without user participation, iterative requirement refinement cannot occur in these models. Engaging users ensures that the resulting softw...
Answer: A. Software Verification
Software verification is a quality assurance practice rather than a core software process activity. The fundamental activities are specification, design and implementation, validation, and evolution. Verification checks...
Answer: C. Concurrent Model
The concurrent development model suits client-server applications exceptionally well. It allows different software engineering activities to exist concurrently. Client-server systems require simultaneous frontend and bac...
