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 business needs1.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.Reference:1: Nokia Bell Labs Distributed Cloud Networks, Unit 2: Cloud Technologies and Features, Section 2.3: Cloud Native applications design2: Nokia Bell Labs Distributed Cloud Networks, Unit 2: Cloud Technologies and Features, Section 2.5: Microservices and Containerization3: Google Cloud, Nokia partner to accelerate cloud-native 5G3

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.Reference:Nokia Cloud Platform,Module by Module - Self Study Note Guide

The statement that best describes the scaling stage of the application life cycle isthe application adjusts its capacity.Scaling is the process of increasing or decreasing the number of resources allocated to an application based on the demand and performance1.Scaling can be done manually or automatically using policies and metrics1. The other statements do not describe the scaling stage, but rather other stages of the application life cycle. The periodic upgrade of the service is part of the maintenance stage, which ensures the reliability and security of the application2.The deployment of the application over the infrastructure is part of the installation stage, which involves the configuration and activation of the application2.The termination and freeing of associated resources is part of the decommissioning stage, which removes the application from the network2.Reference:1: Nokia Bell Labs Distributed Cloud Networks, Unit 4: Operating Your Cloud, slide 232:Nokia Bell Labs Distributed Cloud Networks, Unit 4: Operating Your Cloud, slide 10

Hyperscale computing relies on scalable server architecture.This is true because hyperscale computing is a type of cloud computing that aims to provide massive scalability, performance, and efficiency for large-scale applications and data processing1. Hyperscale computing requires a scalable server architecture that can support thousands or millions of servers that are interconnected by high-speed networks2.Scalable server architecture enables hyperscale computing to handle increasing workloads, optimize resource utilization, and reduce operational costs3.Reference:1: Nokia Bell Labs Distributed Cloud Networks, Unit 4: Operating Your Cloud, Section 4.1: Industry Trends in Data Center Hardware2: How Nokia Bell Labs' new serverless computing design will take cloud computing to the next level43: Nokia Bell Labs 5G Professional Certification - Distributed Cloud Networks1

The characteristics of Cloud Native services are very light weight application and very fast deployment. Cloud Native services are applications that are built using cloud-native design principles, such as microservices, containers, and orchestration. Cloud Native services are very light weight because they are composed of small, independent, and loosely coupled components that can run on any platform and environment. Cloud Native services are very fast to deploy because they can leverage the automation, scalability, and elasticity of the cloud infrastructure, and can be updated or rolled back without affecting the whole application.Reference:Cloud and Network Services: Leading cloud-native and as-a-service delivery models,Nokia Mobile Networks and Bell Labs 5G Cloud Native RAN Professional Certification

Isolation is the networking concept that ensures that each tenant or user of a cloud service has their own network configuration and resources, such as IP addresses, subnets, firewalls, and routers. Isolation provides security, privacy, and performance benefits for the cloud tenants, as they can control and customize their own network settings and avoid interference or conflicts with other tenants. Isolation can be achieved by using different techniques, such as VLANs, VXLANs, VPNs, or network slicing.Nokia Bell Labs 5G Professional Certification - Distributed Cloud Networks | Nokia Distributed Cloud Networks, Unit 2: Cloud Technologies and Features, slide 10Nokia Bell Labs 5G Certification Program - Courses | Nokia, Distributed Cloud Networks, Unit 2: Cloud Technologies and Features Isolation in networking, particularly in the context of cloud computing, refers to the separation of network traffic for different users or tenant environments within a shared infrastructure. This ensures that each tenant's dataand applications remain private and inaccessible to other tenants. Isolation can be achieved through various means, including virtual LANs (VLANs), network virtualization, and software-defined networking (SDN) techniques.The core idea is to provide tenants with the illusion of a private, dedicated network environment, even though the underlying physical infrastructure is shared among multiple tenants. This enables each tenant to have their own network configuration, policies, and management, ensuring security and privacy within a multi-tenant architecture.

On-premise Edge Cloud and Metro Edge Cloud are the cloud deployments that provide the lowest latency.Latency is the time it takes for data to travel from the source to the destination1.On-premise Edge Cloud is a cloud deployment that is located within the premises of the end-user, such as a factory, a hospital, or a campus2.Metro Edge Cloud is a cloud deployment that is located within the same metropolitan area as the end-user, such as a city or a suburb3.Both On-premise Edge Cloud and Metro Edge Cloud reduce the distance and the number of hops that data has to travel, resulting in lower latency and higher performance4. Far Edge Cloud and Central Cloud are not the cloud deployments that provide the lowest latency.Far Edge Cloud is a cloud deployment that is located at the edge of the operator's network, such as a regional data center or a base station3.Central Cloud is a cloud deployment that is located at the core of the operator's network, such as a national data center or a cloud provider3.Both Far Edge Cloud and Central Cloud increase the distance and the number of hops that data has to travel, resulting in higher latency and lower performance4.

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.Reference: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?

The ''Stateless'' service concept is indeed the most efficient for resource usage. In a stateless architecture, each request is treated as an independent transaction, unconnected to any previous request. This means that no state information is stored between transactions, which simplifies the design and scalability of systems. It allows for better resource utilization because there is no need to maintain state information over time, which can be resource-intensive. This approach aligns with the principles of RESTful services and is widely adopted in scalable web applications.
