Nokia BL0-220 Nokia Bell Labs Distributed Cloud Networks Exam Practice Test

Answer : A

The networking concept of ''Underlay'' refers to the physical network layer that provides the connectivity and transport for the overlay network, which is the virtual network layer that runs on top of the underlay network1.The underlay network is composed of routers, switches, links, and protocols that enable the data transmission between different locations2.The underlay network is independent of the overlay network, meaning that it does not need to be aware of the network configuration, policies, or services of the overlay network3.Therefore, option A best describes the underlay network, while options B, C, and D are incorrect.Reference:1:Nokia Bell Labs Distributed Cloud Networks, Unit 2: Cloud Technologies and Features, Topic: Underlay and Overlay Networks2:Module by Module - Self Study Note Guide, DC2.2-- Cloud Options3:Underlay Network - an overview | ScienceDirect Topics, Overview

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 : C

The statement that best describes cloud native operations iscloud 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.Reference:1:Nokia Bell Labs Distributed Cloud Networks, Unit 4: Operating Your Cloud, slide 62:Nokia Bell Labs 5G Certification Program - Blended Learning, Section 2: Distributed Cloud Networks, slide 16

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

Answer : B

It is not possible to run a cloud solution in a Single Node.A cloud solution requires a minimum of three nodes to provide high availability, scalability, and fault tolerance1.A Single Node is a standalone server that does not have any redundancy or load balancing features2. A Single Node can be used for testing or development purposes, but not for production or deployment of cloud applications.

Answer : A

The technology layer function supports automated service delivery by providing the necessary tools and mechanisms to orchestrate, monitor, and optimize the cloud resources and services. The technology layer function consists of four sub-functions: cloud management, cloud orchestration, cloud automation, and cloud analytics. These sub-functions work together to enable the efficient and flexible operation of the cloud ecosystem.
