Nokia Bell Labs Distributed Cloud Networks BL0-220 Exam Questions

Answer : B

OCP stands for Open Compute Project, which is an initiative to design and enable the delivery of the most efficient server, storage and data center hardware designs for scalable computing1.OCP is the primary cloud infrastructure platform to develop, test and deliver Nokia's core network applications and business applications, benefiting from its scalability, flexibility, and advanced orchestration capabilities2.OCP is also part of the Nokia Cloud Platform, which is a TCO optimized solution that combines OCP with Nokia's reference hardware and blueprint architecture2.Reference:1:Open Compute Project, Home Page2:Nokia Cloud Platform,

Answer : D

The most appropriate word to complete the sentence isbenefits.The public cloud ecosystem offers many benefits to users, such as scalability, flexibility, cost-efficiency, and innovation12.Constraints, problems, and operability are not suitable words to describe the advantages of the public cloud ecosystem over the simple consumption of resources.Reference:1:Nokia Bell Labs Distributed Cloud Networks, Unit 1: Cloud Ecosystem, slide 72:Nokia Bell Labs 5G Certification Program - Blended Learning, Section 2: Distributed Cloud Networks, slide 9

Answer : B

Kubernetes is an orchestrator, which is a software system that automates the deployment, scaling, and management of containerized applications1.Kubernetes allows users to define the desired state and configuration of their applications, and then ensures that the actual state matches the desired state2.Kubernetes also provides features such as service discovery, load balancing, storage management, and self-healing3.Therefore, option B best describes Kubernetes, while options A, C, and D are incorrect.Reference:1:Nokia Bell Labs Distributed Cloud Networks, Unit 2: Cloud Technologies and Features, Topic: Microservices and Containerization2:What is Kubernetes? | Kubernetes, Overview3:Kubernetes - an overview | ScienceDirect Topics, Overview

Answer : B, C, D

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.Reference:Nokia Bell Labs 5G Professional Certification - Distributed Cloud Networks, Unit 2: Cloud Technologies and Features, Section 2.3: Cloud Deployment Models.

Answer : B, C, D

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...Reference:1:Data Center Manager: Roles, Responsibilities, and Skills, Introduction2:Nokia Bell Labs Distributed Cloud Networks, Unit 4: Operating Your Cloud, Section 4.1: Industry Trends in Data Center Hardware3: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

Answer : A, C

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.Reference:1: Nokia Bell Labs Distributed Cloud Networks, Unit 5: New Services Automation, Section 5.2: Service Automation2: Nokia Bell Labs Distributed Cloud Networks, Unit 4: Operating Your Cloud, Section 4.2: Network Automation3:Nokia, A1 and Microsoft deploy industry's first 5G edge cloud network slicing solution for enterprises4: Nokia Bell Labs Distributed Cloud Networks, Unit 5: New Services Automation, Section 5.3: Service Automation Benefits and Challenges
