What is the sequence of the evolution of Network Functions?

Show Suggested Answer Hide Answer
Suggested Answer: C

Physical Network Functions (PNFs) are the traditional network functions that run on dedicated hardware appliances, such as routers, switches, firewalls, etc1.Virtual Network Functions (VNFs) are the network functions that run on virtual machines (VMs) on top of a common hardware platform, such as servers, storage, and network1.Cloud-Native Network Functions (CNFs) are the network functions that run on containers orchestrated by Kubernetes on a cloud infrastructure1.The evolution of Network Functions reflects the trend of moving from hardware-centric to software-centric and cloud-based solutions, which offer more flexibility, scalability, and efficiency12.Reference:1:Nokia Bell Labs Distributed Cloud Networks, Unit 2: Cloud Technologies and Features, slide 182:Nokia Bell Labs 5G Certification Program - Blended Learning, Section 2: Distributed Cloud Networks, slide 11

Haha, this exam is really testing our network knowledge! I'm going to go with C. Physical Network Functions -> Virtual Network Functions -> Cloud-Native Network Functions. It's the classic progression, isn't it?

I'm feeling confident about A. Cloud-Native Network Functions -> Physical Network Functions -> Virtual Network Functions. It just makes the most logical sense to me, starting with the most modern approach and then working backwards.

Hmm, this is a tough one. I'm going to go with D. Virtual Network Functions -> Cloud-Native Network Functions -> Physical Network Functions. It's a bit counterintuitive, but I think the industry is moving towards more cloud-centric solutions.

Well, I'm not entirely sure, but I'm leaning towards B. Virtual Network Functions -> Physical Network Functions -> Cloud-Native Network Functions. It seems to follow the progression of virtualization and then cloud-based functions.
