Top 5 Technical Interview Questions Asked for Network Engineer
- Explanation: This question tests your understanding of the two fundamental transport layer protocols. TCP (Transmission Control Protocol) is connection-oriented and ensures data delivery through acknowledgments, retransmissions, and flow control. UDP (User Datagram Protocol), on the other hand, is connectionless and does not guarantee delivery, making it faster but less reliable.
- Follow-up: You might be asked about specific use cases for each protocol, such as when to use TCP over UDP or vice versa.
- Explanation: Subnetting divides a larger network into smaller, more manageable sub-networks, or subnets. This helps in reducing network traffic, improving security, and efficiently utilizing IP addresses. Interviewers expect you to explain how to calculate subnets, given an IP address and a subnet mask, and discuss the significance of subnetting in network design.
- Example: You may be given an IP address and asked to determine the subnet, network, and broadcast address.
- Explanation: This question assesses your problem-solving approach and practical troubleshooting skills. A structured answer would include verifying physical connections, checking device configurations, reviewing logs, using tools like
ping,traceroute, andnetstat, and systematically isolating the issue to a specific device or segment of the network. - Tools Mentioned: Interviewers might expect you to mention specific networking tools and techniques, such as using a packet sniffer (e.g., Wireshark) for deeper analysis.
- Explanation: VLAN (Virtual Local Area Network) is used to segment a physical network into multiple logical networks. This helps in reducing broadcast domains, enhancing security, and improving network management. You should explain how VLAN tagging works, the concept of trunk ports, and how VLANs can be implemented on switches.
- Use Cases: You might be asked to describe a scenario where VLANs are necessary, such as in a multi-department organization needing separate broadcast domains for each department.
- Explanation: This question targets your knowledge of routing protocols. OSPF (Open Shortest Path First) is an interior gateway protocol (IGP) used within an autonomous system, relying on the shortest path first algorithm. BGP (Border Gateway Protocol) is an exterior gateway protocol (EGP) used to route data between different autonomous systems, focusing on policy-based routing.
- Depth: You may be asked to compare the scalability, convergence times, and use cases for each protocol, as well as how they handle route advertisement and decision-making.
