Question 2

What event will trigger the auto-healing operation?



Answer : D

A fault detection event will trigger the auto-healing operation.Auto-healing is a feature of cloud networks that enables the automatic recovery of resources or services from failures or errors1.Fault detection is the process of identifying and locating faults in the network using various methods such as monitoring, logging, or testing2.When a fault is detected, the auto-healing operation will initiate the appropriate actions to restore the normal functioning of the network, such as restarting, repairing, or replacing the faulty components1. Threshold, warning message, and new status are not events that trigger the auto-healing operation.Threshold is a predefined value or limit that indicates the acceptable performance or behavior of a resource or service3.Warning message is a notification or alert that informs the user or operator about a potential problem or risk in the network4. New status is a change or update in the state or condition of a resource or service, such as active, inactive, or degraded.


Question 3

Select the best option below to complete the following sentence.

The_________is used to orchestrate and manage traffic through VNFs.



Answer : B

The best option to complete the sentence isVNF 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.Reference:1:VNF Forwarding Graph and Network Service-Beginner's Guide, Introduction2:A survey of VNF forwarding graph embedding in B5G/6G networks - Springer, Section 13:A Deep Reinforcement Learning Approach for VNF Forwarding Graph Embedding, Section I


Question 4

Which of the following best describes the Management Plane?



Answer : B

The Management Plane is the logical layer of a network that provides network management and control functions, such as configuration, monitoring, fault detection, performance analysis, and security1.The Management Plane interacts with the Control Plane and the Data Plane, which are responsible for traffic routing and forwarding, respectively2.The Management Plane also supports the orchestration and automation of network services across the distributed cloud3.Therefore, option B best describes the Management Plane, while options A and C are incorrect.Reference:1:Nokia Bell Labs Distributed Cloud Networks, Unit 4: Operating Your Cloud, Topic: Management Plane2:Module by Module - Self Study Note Guide, DC4.1-- Industry Trends in Data Center Hardware3:Nokia Bell Labs Distributed Cloud Networks, Unit 5: New Services Automation, Topic: Management and Orchestration


Question 5

Which of the following contains the configuration of a VNF or CNF?



Answer : B

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.
