 The best option to complete the sentence is VNF Forwarding Graph. A VNF Forwarding Graph (VNF-FG) is a logical representation of a network service that consists of a set of interconnected Virtual Network Functions (VNFs) and the traffic flows between them1. The VNF-FG is used to orchestrate and manage traffic through VNFs by specifying the order and the requirements of the VNFs that need to be traversed by the traffic2. The VNF-FG also defines the connection points, virtual links, and network forwarding paths that are involved in the service delivery3. References: 1: VNF Forwarding Graph and Network Service-Beginner’s Guide, Introduction 2: A survey of VNF forwarding graph embedding in B5G/6G networks - Springer, Section 1 3: A Deep Reinforcement Learning Approach for VNF Forwarding Graph Embedding, Section I

All life cycle stages are clearly identified. Comprehensive Explanation and References of Correct Answer: Life cycle management is the process of managing the development, deployment, operation, and decommissioning of cloud applications and services. It involves defining the requirements, design, testing, deployment, monitoring, scaling, updating, and retiring of cloud resources. One of the benefits of life cycle management is that it provides clarity and visibility into the different stages of the cloud service, from inception to termination. This helps to ensure quality, efficiency, security, and reliability of the cloud service, as well as to optimize the use of resources and reduce costs.

Cloud resources are made available to customers as virtualized resources. Virtualization is the process of creating a software-based representation of a physical resource, such as a server, a storage device, or a network device. Virtualization allows multiple customers to share the same physical resource, while isolating their data and applications from each other. Virtualization also enables customers to access cloud resources on demand, without having to worry about the underlying hardware or infrastructure. Virtualization is one of the key technologies that enable cloud computing and its benefits. References: Nokia Cloud Platform, Module by Module - Self Study Note Guide

The properties related to a private cloud are high CAPEX and full control. CAPEX stands for capital expenditure, which is the money spent on acquiring or upgrading physical assets such as servers, storage, and network equipment. A private cloud requires high CAPEX because the cloud owner has to invest in building and maintaining the cloud infrastructure. Full control means that the cloud owner has the exclusive authority and responsibility over the cloud resources, security, and operations. A private cloud offers full control because the cloud owner can customize the cloud according to their specific needs and preferences, and can ensure the privacy and compliance of their data and applications. References: Nokia Cloud Platform, Module by Module - Self Study Note Guide

 The 5G Core control plane is responsible for managing the network functions, services, and resources, such as authentication, authorization, session management, policy control, mobility management, etc.1. The 5G Core control plane can be deployed in a distributed cloud architecture, which consists of different cloud layers that have different characteristics and roles2. The Metro Edge Cloud is a cloud layer that is located near the access network, and provides low latency, high bandwidth, and local processing for the control plane functions3. The Core/Central Cloud is a cloud layer that is located in the core network, and provides high availability, scalability, and security for the control plane functions4. The distributed cloud architecture enables the 5G Core control plane to optimize the network performance, efficiency, and flexibility, and to support various use cases and applications. References: 1: Nokia Bell Labs Distributed Cloud Networks, Unit 1: Cloud Ecosystem, Section 1.2: Cloud Architecture 2: Nokia Bell Labs Distributed Cloud Networks, Unit 1: Cloud Ecosystem, Section 1.3: Distributed Cloud 3: Nokia Bell Labs Distributed Cloud Networks, Unit 3: Cloud Resource Planning, Section 3.2: Cloud Resource Planning for Distributed Cloud 4: Nokia Bell Labs Distributed Cloud Networks, Unit 3: Cloud Resource Planning, Section 3.3: Cloud Resource Planning for Central Cloud : Nokia Bell Labs Distributed Cloud Networks, Unit 5: New Services Automation, Section 5.1: Distributed Cloud Services Automation
