Explanation:

A YAML XML template file contains the configuration of a VNF or CNF. A VNF stands for Virtual Network Function, which is a software-based network function that runs on a virtual machine or a container. A CNF stands for Cloud-native Network Function, which is a network function that is designed and implemented using cloud-native principles and technologies, such as microservices, containers, and Kubernetes. A YAML XML template file is a file that defines the structure, parameters, and dependencies of a VNF or CNF, as well as the resources and policies required to deploy and manage it. A YAML XML template file is based on the TOSCA (Topology and Orchestration Specification for Cloud Applications) standard, which is a language for describing the components and relationships of complex cloud applications. A YAML XML template file is used by the MANO (Management and Orchestration) system to instantiate, configure, and operate a VNF or CNF on the cloud infrastructure.Reference:Nokia Bell Labs 5G Professional Certification - Distributed Cloud Networks, Unit 2: Cloud Technologies and Features, Section 2.4: Cloud Software and Hardware Resources.
