Distributed Computing: A Comprehensive MCQ Companion — 610 Duplicate-Free Multiple-Choice Questions with Answers and Explanations

Distributed Computing: A Comprehensive MCQ Companion is a structured practice and revision resource designed to strengthen conceptual understanding and problem-solving skills in distributed computing. The book contains 610 duplicate-free multiple-choice questions with answers and concise explanations. It progresses systematically from foundational principles to advanced and contemporary distributed-system technologies. Rather than focusing on simple memorisation, the questions are designed to test definitions, conceptual distinctions, reasoning, algorithmic behaviour, architectural trade-offs and practical system-design judgment. Major topics include distributed system models and architectures, communication, naming, synchronization, mutual exclusion, leader election, distributed snapshots, deadlocks, consensus and agreement protocols, replication, consistency, fault tolerance, distributed storage and file systems, stream processing, cloud and edge computing, microservices, container orchestration, observability, resilience and modern distributed platforms. The duplicate-free structure ensures that each question contributes a distinct learning objective instead of repeating the same concept in different wording. Clear explanations accompanying the answers make the book suitable for both examination preparation and independent study. The book is intended for undergraduate and postgraduate students of computer science and related disciplines, faculty members, researchers, certification candidates, competitive-examination aspirants and professionals preparing for technical interviews or system-design roles.
