 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

The available options to interconnect private Datacenters are VPN and Backbone. VPN stands for Virtual Private Network, which is a secure and encrypted connection between two or more networks over the public internet. Backbone is a high-capacity network that connects different data centers across regions or countries. Both VPN and Backbone provide reliable, scalable, and secure data center interconnect (DCI) solutions for private/hybrid clouds. References: Nokia Cloud DCI offers a more scalable, reliable and secure way to connect data centers in private/hybrid clouds, Nokia business-critical cloud DCI solutions support multiple DCI applications, from real-time business continuity and disaster recovery, to synchronous data replication and cloud backup, Nokia partners with IP Telecom to deliver quantum-safe data center connectivity

Adaptability is the most critical benefit a cloud native deployment provides when deploying applications in complex and very low predictive environments. Cloud native applications are designed to be modular, scalable, resilient, and portable across different cloud platforms1. They can leverage the cloud features such as automation, orchestration, and service discovery to dynamically adjust to changing conditions and demands2. This enables them to cope with the complexity and unpredictability of the environments they operate in, such as edge computing, industrial automation, and smart cities3. Capability and reliability are also important benefits of cloud native deployment, but they are not the most critical ones. Capability refers to the ability to deliver high-performance and feature-rich applications that meet the user and businessneeds1. Reliability refers to the ability to ensure the availability and consistency of the applications despite failures or errors1. However, these benefits are not sufficient if the applications cannot adapt to the evolving and diverse scenarios they face in the real world. References: 1: Nokia Bell Labs Distributed Cloud Networks, Unit 2: Cloud Technologies and Features, Section 2.3: Cloud Native applications design 2: Nokia Bell Labs Distributed Cloud Networks, Unit 2: Cloud Technologies and Features, Section 2.5: Microservices and Containerization 3: Google Cloud, Nokia partner to accelerate cloud-native 5G3

Service automation and network automation are two techniques that provide the benefit of faster deployment. Service automation is the process of using software tools and predefined workflows to create, configure, and manage cloud services without human intervention1. Network automation is the process of using software tools and predefined policies to orchestrate, monitor, and optimize network resources and functions without human intervention2. Both techniques can reduce the time, cost, and errors associated with manual service deployment and configuration, and enable faster and more agile service delivery and network operations3. Manual service deployment and manual configuration are not techniques that provide the benefit of faster deployment, as they require human intervention and are prone to human errors, delays, and inefficiencies4. References: 1: Nokia Bell Labs Distributed Cloud Networks, Unit 5: New Services Automation, Section 5.2: Service Automation 2: Nokia Bell Labs Distributed Cloud Networks, Unit 4: Operating Your Cloud, Section 4.2: Network Automation 3: Nokia, A1 and Microsoft deploy industry’s first 5G edge cloud network slicing solution for enterprises 4: Nokia Bell Labs Distributed Cloud Networks, Unit 5: New Services Automation, Section 5.3: Service Automation Benefits and Challenges

The two main options to interconnect private and public clouds are VPN and WAN. VPN stands for Virtual Private Network, which is a secure and encrypted connection between two or more networks over the public internet. VPN allows private and public clouds to communicate with each other without exposing their data or traffic to third parties. WAN stands for Wide Area Network, which is a network that spans a large geographic area, such as a country or a continent. WAN allows private and public clouds to interconnect across different regions or locations, using high-speed and high-capacity links. Both VPN and WAN provide reliable, scalable, and flexible solutions for hybrid cloud scenarios, where private and public clouds work together to deliver optimal performance and efficiency. References: Nokia Bell Labs 5G Professional Certification - Distributed Cloud Networks, Cloud Data Center Interconnect for Large Enterprises, 5G Core on cloud: go public, private or a bit of both?

Software as a Service (SaaS) is a cloud computing offering that provides users with access to a vendor's cloud-based software. Users do not install applications on their local devices. Instead, the applications reside on a remote cloud network accessed through the web or an API. Within this context, Database-as-a-Service (DBaaS) is considered a form of SaaS, where the service provider manages the database's installation, maintenance, backup, and scaling needs on behalf of the customer. Platform-as-a-Service (PaaS) provides a platform allowing customers to develop, run, and manage applications without dealing with the complexity of building and maintaining the infrastructure typically associated with developing and launching an app. PaaS can include various software components, including database management systems, and thus can be considered a subset of SaaS.

The properties related to a public cloud are for users, there is no cloud infrastructure operation and easy scaling. A public cloud is a cloud service that is offered by a third-party provider over the public internet, and is available to anyone who wants to use or purchase it1. Users of public cloud do not need to operate or maintain the cloud infrastructure, as it is the responsibility of the cloud provider2. Public cloud also offers easy scaling, as users can quickly and dynamically provision or release resources according to their needs2. Public cloud is suitable for applications that have unpredictable or variable demand, or that do not require a high level of security or customization3. References: 1: Nokia Bell Labs Distributed Cloud Networks, Unit 1: Cloud Ecosystem, Section 1.1: Cloud Types 2: Nokia Bell Labs Distributed Cloud Networks, Unit 2: Cloud Technologies and Features, Section 2.1: Cloud Computing 3: Nokia and DISH to deploy first 5G standalone core network in the public cloud with AWS, Press Release

A data center manager is responsible for overseeing the operation, maintenance, and security of a data center, as well as planning and implementing changes and improvements1. To perform these tasks, a data center manager needs to have appropriate tools that can monitor, control, and automate the data center resources, such as servers, storage, network, power, cooling, etc.2. A data center manager also needs to enable people, such as data center staff, engineers, technicians, and customers, to access, use, and manage the data center services and applications3. Moreover, a data center manager needs to follow an effective process methodology that can ensure the quality, efficiency, and reliability of the data center operations, such as ITIL, DevOps, Agile, etc… References: 1: Data Center Manager: Roles, Responsibilities, and Skills, Introduction 2: Nokia Bell Labs Distributed Cloud Networks, Unit 4: Operating Your Cloud, Section 4.1: Industry Trends in Data Center Hardware 3: Nokia Bell Labs Distributed Cloud Networks, Unit 4: Operating Your Cloud, Section 4.2: Data Center Operations : Nokia Bell Labs Distributed Cloud Networks, Unit 4: Operating Your Cloud, Section 4.3: Data Center Management Methodologies

Latency, Privacy and Capacity are the three key drivers required for video-based service in on-premise cloud. Latency refers to the delay between the source and the destination of a video stream, which affects the quality of experience for the end-users. Privacy refers to the protection of the video content and the user data from unauthorized access or leakage. Capacity refers to the ability of the network and the cloud to handle the high bandwidth and storage demands of video applications. On-premise cloud is a cloud deployment model where the cloud infrastructure is located within the enterprise premises, and is managed by the enterprise or a third-party service provider. On-premise cloud can offer lower latency, higher privacy and greater capacity for video-based service than public cloud, which is located outside the enterprise premises and is shared by multiple tenants. References: Nokia Bell Labs 5G Professional Certification - Distributed Cloud Networks, Unit 2: Cloud Technologies and Features, Section 2.3: Cloud Deployment Models.

 Distributed cloud is a concept that refers to the deployment of cloud services across multiple locations, such as public, private, hybrid, or edge clouds1. Cloud options are the different types of cloud models that can be used to meet the specific needs and requirements of different applications and users2. Cloud options are complementary with distributed cloud, as they enable the flexibility and scalability of cloud services across the cloud continuum3. Therefore, option B is the correct statement, while options A and C are incorrect. References: 1: Nokia Bell Labs Distributed Cloud Networks, Unit 2: Cloud Technologies and Features, Topic: Distributed Cloud Description 2: Nokia Bell Labs Distributed Cloud Networks, Unit 2: Cloud Technologies and Features, Topic: Cloud Options 3: Cloud continuum | Nokia, Overview

The statement that best describes cloud native operations is cloud native provides operation adaptability. Cloud native operations are based on the principles of agility, resilience, and automation, which enable the cloud to adapt to changing demands and conditions12. Cloud native is not only operational by AI, nor does it rely only on network automation. AI and automation are tools that enhance the cloud native operations, but they are not the only factors that define them12. Cloud native design does not limit scalability, but rather enables it by using microservices, containers, and orchestration12. References: 1: Nokia Bell Labs Distributed Cloud Networks, Unit 4: Operating Your Cloud, slide 6 2: Nokia Bell Labs 5G Certification Program - Blended Learning, Section 2: Distributed Cloud Networks, slide 16

 Your apps need cloud resources which are allocated and then provisioned. Allocation is the process of assigning cloud resources to a specific app or service, based on the requirements and availability1. Provisioning is the process of configuring and activating the allocated cloud resources, making them ready to use by the app or service2. Commissioning, instantiation, starting, and distribution are not the correct terms to complete the sentence. Commissioning is the process of testing and verifying the cloud resources before they are allocated3. Instantiation is the process of creating an instance of an app or service, which is a running copy of the app or service that uses the provisioned cloud resources4. Starting is the process of launching an instance of an app or service, which can be done manually or automatically. Distribution is the process of spreading the cloud resources across different locations or domains, to achieve scalability, redundancy, or performance. Termination is the process of deleting or releasing the cloud resources that are no longer needed by the app or service.

Multitenancy in cloud computing defines a set of cloud resources shared by several customers. Multitenancy is a feature of cloud computing that allows multiple customers, or tenants, to use the same cloud infrastructure and services, such as servers, storage, network, and applications, while maintaining their own data and configuration. Multitenancy enables cloud providers to optimize the utilization and allocation of cloud resources, reduce the cost and complexity of cloud operations, and offer scalable and flexible services to different customers. Multitenancy also benefits customers by providing them with on-demand access to cloud resources, pay-per-use pricing models, and enhanced security and isolation. The other options are not correct definitions of multitenancy in cloud computing. A set of cloud resources isolated from each other is a single-tenant model, where each customer has its own dedicated cloud infrastructure and services. A set of cloud resources located in different data centers is a distributed cloud model, where cloud resources are spread across multiple physical locations to provide low latency, high availability, and local compliance. A set of cloud resources assigned to the same network slice is a network slicing model, where a logical network is created over a sharedphysical network to support specific applications and customers with customized performance, quality, and security. References: Nokia Bell Labs 5G Professional Certification - Distributed Cloud Networks, Unit 2: Cloud Technologies and Features, Section 2.2: Cloud Characteristics.

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

Closed loop automation Comprehensive Explanation and References of Correct Answer: AI/ML based operation requires pre-defined policies, open APIs, and closed loop automation to enable intelligent and adaptive cloud management and orchestration. Pre-defined policies provide the rules and objectives for the cloud resources and services, such as performance, security, and cost. Open APIs allow the communication and integration of different cloud components and platforms, such as Nokia’s 5G Edge Slicing solution and Microsoft Azure edge and cloud. Closed loop automation enables the continuous monitoring, analysis, and optimization of the cloud ecosystem based on the feedback from the AI/ML algorithms.
