👉Networking Interview:

• A networking interview typically assesses your knowledge and understanding of networking concepts, protocols, hardware, and troubleshooting techniques. 
• Here are some common questions that may be asked in a networking interview:

1. Basic Networking Concepts:

• What is a subnet mask, and how does it work?
• What is the OSI model? Can you explain each of its layers?
• What is the difference between TCP and UDP?
• What is an IP address, and how is it classified?
• What is a DNS and how does it work?

2. Routing and Switching:

• What is the difference between a router and a switch?
• What is a VLAN and how is it used?
• What is the purpose of a routing table?
• Explain how a MAC address works and where it is used.
• What is OSPF, and how does it differ from RIP?

3. Network Security:

• What is a firewall, and what are the different types?
• What is NAT (Network Address Translation)?
• Can you explain the difference between VPN and VLAN?
• What is SSL/TLS and how is it used in networking?

4. Troubleshooting:

• How would you troubleshoot a network connectivity issue?
• What commands would you use to check network connectivity?
• What is ping and traceroute, and how are they used in troubleshooting?

5. Advanced Topics:

• What is QoS (Quality of Service), and why is it important?
• What is the difference between IPv4 and IPv6?
• Can you explain the concept of BGP (Border Gateway Protocol)?
• What is DHCP, and how does it work?

6. Hands-on or Scenario-based Questions:

• How would you set up a network with multiple devices and ensure proper configuration?
• What steps would you take if a particular website is unreachable but local devices can communicate with each other.

👉Preparation Tips:

• Review Networking Fundamentals: Be clear on topics like the OSI model, IP addressing, routing protocols, and basic security practices.
• Practice Commands: Be familiar with tools like ping, traceroute, nslookup, netstat, and others.
• Hands-On Practice: If possible, try to set up a network or use a simulator like Cisco Packet Tracer or GNS3 to practice configurations.
• Stay Updated: Familiarize yourself with current networking technologies, such as cloud computing, SD-WAN, and network automation.
