Top Networking Interview Questions and Answers for 2025

1. What is a Network?
   A system of interconnected devices to share data and resources. Be able to differentiate LAN, WAN, and MAN. jobzshala employers seek concise, technically correct answers.
2. What is the OSI Model?
   The OSI Model divides networking into seven layers: Physical, Data Link, Network, Transport, Session, Presentation, and Application. Each layer has a unique function for network communication setup and troubleshooting.
3. Define IP Address and its Types
   IP addresses identify networked devices; IPv4 is 32 bits, IPv6 is 128 bits. Show clarity in concepts, as required by IT jobs listed on Jobzshala.
4. Differentiate Between TCP and UDP
   TCP provides reliable, connection-oriented communication. UDP is faster, connectionless. Relate your answer to real-life: TCP for emails, UDP for gaming.
5. What is Subnetting?
   Subnetting splits big networks into smaller ones for efficient traffic management. Explain subnet masks, IP ranges, and CIDR notations clearly.
6. What is DHCP and Its Function?
   DHCP assigns IP addresses automatically to devices, reducing manual errors and supporting smooth corporate operations.
7. Define DNS and Its Importance
   DNS translates domain names to IP addresses; also explain DNS caching and troubleshooting steps as expected in networking job interviews.
8. How Do Switches Differ from Routers?
   Switches connect devices within the same network; routers connect different networks and handle routing and security.
9. What is a VPN?
   A Virtual Private Network encrypts data over public networks. Explain encryption, tunneling, and authentication.
10. Explain MAC Address
    A hardware identifier assigned to each network device for unique identification and communication in the network.

Scenario-Based Networking Questions and Answers

• Scenario 1: How would you troubleshoot a network outage in an enterprise setup?
  Answer: Use ping commands, check cables, verify IP settings, and escalate if needed.
• Scenario 2: What steps will you take if DNS resolution fails?
  Answer: Flush DNS cache, update settings, check server reachability.
• Scenario 3: How do you secure a corporate Wi-Fi network?
  Answer: Implement WPA3 encryption, enable MAC filtering, hide SSID.

Practicing real scenarios helps students develop technical and problem-solving confidence for interviews.

Networking Protocols and Security Questions

• What are the main functions of ARP? ARP maps IP addresses to MAC addresses for data-link communication.
• Describe HTTPS vs HTTP. HTTPS uses SSL/TLS to secure data transfer, unlike HTTP.
• Explain NAT and its types. NAT changes IP headers so multiple devices share one public IP address.

Protocol and security questions validate both management and protection skills.
