Data Serialization Formats (JSON, Avro): Practice Tests is a comprehensive course designed to help learners understand the fundamentals and advanced concepts of modern data serialization formats. This course focuses on JSON and Avro, two of the most widely used technologies for structured data exchange in APIs, distributed systems, big data platforms, and backend applications.
The course contains 300+ carefully designed multiple-choice questions with answers and detailed explanations to strengthen both theoretical understanding and practical knowledge. It is suitable for beginners, students, developers, data engineering learners, and professionals preparing for interviews, certifications, or technical assessments.
In this course, learners will explore important topics including JSON syntax, objects, arrays, data types, Avro schemas, schema evolution, serialization and deserialization concepts, binary encoding, interoperability, and distributed data exchange systems.
What you will learn:
JSON fundamentals and syntax rules
Avro schemas and serialization concepts
Arrays, objects, maps, enums, and records
Serialization and deserialization processes
Schema evolution and compatibility handling
Data exchange in APIs and distributed systems
Binary vs text-based serialization formats
Common JSON and Avro parsing issues
Interview and certification-oriented practice questions
This course is designed in a simple and easy-to-understand format so learners can gradually build confidence while practicing MCQs step by step. By the end of the course, students will have a strong understanding of JSON and Avro concepts and will be better prepared for technical interviews, exams, and real-world applications involving structured data serialization.
