SDN
SDN (Software Defined Networking) is a modern approach to managing computer networks. Think of it like having a central control system that directs traffic on a complex highway system. Instead of having individual traffic controllers at each intersection, there's one central system making all the decisions. This makes networks easier to manage, more flexible, and less expensive to run. It's similar to how cloud computing changed the way we manage servers - SDN is doing the same for networks. When you see SDN in a resume, it means the person has experience with this modern way of network management.

Example Interview Questions
Senior Level Questions
Q: How would you explain the benefits of SDN to business stakeholders?
Expected Answer: A senior candidate should be able to explain SDN benefits in business terms: cost savings through centralized management, faster network changes, improved security, and better application performance. They should provide real-world examples.
Q: What experience do you have with large-scale SDN deployments?
Expected Answer: Look for answers that demonstrate leadership in planning and executing network transformations, problem-solving abilities, and understanding of both technical and business impacts.
Mid Level Questions
Q: What are the main differences between traditional networking and SDN?
Expected Answer: Should explain how SDN separates network control from data transmission, making networks more flexible and easier to manage from a central point, using simple comparisons.
Q: How do you monitor and troubleshoot SDN environments?
Expected Answer: Should describe basic monitoring tools, common problems, and systematic approaches to finding and fixing network issues in SDN environments.
Junior Level Questions
Q: What basic components make up an SDN architecture?
Expected Answer: Should be able to describe the basic parts: the central controller, the applications that run on it, and the network devices it controls, in simple terms.
Q: What are some basic SDN security considerations?
Expected Answer: Should demonstrate understanding of basic network security concepts and how they apply to SDN, such as protecting the controller and securing communication channels.
