Master Nokia BL0-220 Exam with Reliable Practice Questions

Correct : B

Containers as a Service (CaaS) is the same as the E2E Orchestrator for VMs for containers. CaaS is a cloud service model that allows users to deploy and manage containerized applications on a cloud platform. CaaS provides the necessary infrastructure, orchestration, networking, and security for running containers. The E2E Orchestrator for VMs is a Nokia solution that provides similar capabilities for virtual machines (VMs). The E2E Orchestrator for VMs enables the creation, deployment, and management of VMs on a distributed cloud platform. It also supports network slicing, security, and automation features.

Correct : A

Low latency is the primary benefit of an Edge Cloud.Edge Cloud is a distributed cloud architecture that brings cloud resources closer to the end users and devices, reducing the distance and delay for data transmission1.Low latency is crucial for many 5G use cases that require real-time responsiveness, such as autonomous driving, remote surgery, smart manufacturing, etc2.Low cost, large bandwidth, and high availability are not the primary benefits of an Edge Cloud, although they may be achieved depending on the deployment scenario and the service level agreement.Reference:1: Nokia Bell Labs Distributed Cloud Networks, Unit 1: Cloud Ecosystem, Section 1.2: Cloud Types2: Nokia Bell Labs Distributed Cloud Networks, Unit 5: New Services Automation, Section 5.1: Industry 4.0 Use Cases

Correct : A, B

The main parameters of policy-based auto-scaling arethresholdandmin/max values.Threshold is the value of a metric that triggers the scaling action, such as CPU utilization or memory usage1.Min/max values are the minimum and maximum number of instances or resources that can be scaled up or down1. Priority and description are not parameters of policy-based auto-scaling.Priority is the order of execution of policies in case of conflicting or overlapping conditions2.Description is the optional text that provides additional information about the policy2.Reference:1:Nokia Bell Labs Distributed Cloud Networks, Unit 4: Operating Your Cloud, slide 242:Nokia CloudBand Application Manager User Guide, Chapter 9: Scaling Policies, page 151

Correct : B

Different paths for a NF providing Cloud Resilience are defined in aNetwork Service Descriptor. A Network Service Descriptor (NSD) is a document that describes the topology, configuration, and requirements of a network service.It specifies the network functions (NFs) that compose the service, the virtual links that connect them, and the forwarding graphs that define the traffic flows between them1.A NSD also defines the resilience policies for each NF, such as the number of instances, the scaling triggers, the fault management actions, and the alternative paths in case of failures2. A Network Function template, an NS Orchestrator configuration, and an NFV Orchestrator configuration are not the correct options to complete the sentence.A Network Function template is a document that describes the characteristics and requirements of a single network function, such as the virtualization environment, the resources, the interfaces, and the dependencies1.An NS Orchestrator configuration is a set of parameters that control the behavior and operation of the NS Orchestrator, which is a component that manages the lifecycle of network services3.An NFV Orchestrator configuration is a set of parameters that control the behavior and operation of the NFV Orchestrator, which is a component that coordinates the allocation and release of resources for network services3.Reference:1: Nokia Bell Labs Distributed Cloud Networks, Unit 3: Cloud Resource Planning, Section 3.2: Network Function2: Nokia Bell Labs Distributed Cloud Networks, Unit 3: Cloud Resource Planning, Section 3.3: Network Service Descriptor Role3: Nokia Bell Labs Distributed Cloud Networks, Unit 4: Operating Your Cloud, Section 4.1: Industry Trends in Data Center Hardware

Correct : C

Monolithic applications are a mono-block functional service because they are composed of a single, self-contained unit that contains all the components of the application, such as the user interface, business logic, data access, etc1.Monolithic applications are not smaller in size than cloud native applications, as they tend to grow larger and more complex over time2.Monolithic applications are not more reliable than microservices, as they are more prone to failures, bugs, and performance issues due to the tight coupling and interdependency of the components3.Monolithic applications do not involve the most complex management strategy, as they are easier to develop, test, and deploy initially, but they become harder to maintain, scale, and update as the application evolves4.Reference:1: Nokia Bell Labs Distributed Cloud Networks, Unit 2: Cloud Technologies and Features, Section 2.4: Cloud Application Architectures2:Monolithic Architecture3:Microservices vs Monolithic Architecture4:Monolithic vs. Microservices Architecture
