Here are most frequently asked interview questions for Network engineers. I will also try to answer them at some later stage.
1. What is ARP and how does it work? Let's say I have 2 computers connected to a switch. How does ARP work here?
2. On which layer does ICMP work?
3. What are the roles of Transport layer in OSI model?
4. What is the difference between TCP and UDP?
5. How is TCP reliable?
6. What makes TCP connection oriented?
7. What is 3 way handshake in TCP?
8. What parameters are negotiated during a 3 way handshake?
9. What is sliding window concept?
10. How does trace route work?
