NFV
NFV (Network Functions Virtualization) is a modern approach to building and managing telecommunications networks. Instead of using specialized physical hardware boxes for different network tasks, NFV turns these functions into software that can run on standard computers. Think of it like turning physical appliances into computer apps - just as you can have many apps on your phone instead of carrying multiple devices, NFV lets telecom companies run multiple network functions on regular servers. This makes networks more flexible and usually less expensive to operate. When you see NFV in a resume, it means the person has experience with this modern way of building telecommunications networks.

Senior Level Questions
Q: How would you explain the business benefits of NFV to a company's leadership?
Expected Answer: A senior professional should discuss cost savings from using standard hardware, faster deployment of new services, reduced maintenance needs, and ability to scale services up or down quickly based on customer demand.
Q: What challenges have you faced in NFV deployments and how did you overcome them?
Expected Answer: Should describe real-world examples of managing the transition from traditional hardware to NFV, including handling service continuity, training staff, and ensuring performance meets requirements.
Mid Level Questions
Q: What's the difference between NFV and traditional networking?
Expected Answer: Should explain how NFV replaces hardware-based network functions with software running on standard servers, and the advantages this brings in terms of flexibility and cost.
Q: How do you ensure reliability in an NFV environment?
Expected Answer: Should discuss backup systems, monitoring tools, and ways to maintain service quality when running network functions as software instead of dedicated hardware.
Junior Level Questions
Q: What is NFV and why is it important?
Expected Answer: Should be able to explain that NFV turns network equipment functions into software and why this matters for modern telecommunications networks.
Q: What basic components make up an NFV system?
Expected Answer: Should describe the basic parts: the standard servers that run the software, the software versions of network functions, and the system that manages everything.
