Are you preparing for a networking interview? Planning to take the CCNA or another certification? Or simply want to test how strong your fundamentals really are?

This Computer Networking Fundamentals: Interview Test Series is designed to help you validate your understanding of the most essential networking concepts through well-structured, real-world practice tests. Whether you're a student, a new graduate, or an IT professional brushing up on your basics, this course gives you a clear edge when it matters most.

The series is divided into six carefully designed test modules. Each one includes 75 thoughtfully crafted multiple-choice questions that reflect actual interview scenarios, certification exams, and technical screening rounds. This course will not only test your knowledge—it will stretch your reasoning and help you recognize patterns, fix blind spots, and sharpen your problem-solving skills.

What’s Inside the Test Series?

Test 1: Network Basics and Architecture
Understand how networks are structured. Get confident with topologies, network types, and the foundational client-server models that power modern communication.

Test 2: OSI Model and Data Flow
Explore the critical 7-layer OSI model, how data is encapsulated, and how devices interact from layer to layer. A must-know topic for every network engineer.

Test 3: IP Addressing and Subnetting
Put your IP skills to the test. Learn to calculate subnets, decipher CIDR blocks, understand binary logic, and design efficient address spaces.

Test 4: Routing and Switching Fundamentals
Examine how data moves. From routing protocols to switching logic, MAC addressing, and gateway configuration—this test ensures you know the path.

Test 5: TCP, UDP, and Port Numbers
Get clear on protocols that matter. Dive into TCP vs UDP, port mappings, the handshake process, and how connections are made and managed across services.

Test 6: Common Protocols and Network Services
Test your knowledge of critical protocols like DNS, HTTP, DHCP, FTP, and SMTP. Know how they function and why they matter in real-world networks.
