Which of the following statements are correct regarding the characteristics of microservices? (Select 2)
Answer(s): A,C
Microservices are a design principle for cloud-native applications, where each application is composed of a set of small, independent, and loosely coupled services that communicate with each other through well-defined interfaces1. Microservices have the following characteristics2:Microservices are chained in order to build an application, meaning that they are connected by a network and exchange messages or data to perform a specific function or task. Microservices are differentiated by function, meaning that each microservice has a single responsibility and performs a distinct function within the application. Microservices are derived from monolithic applications, meaning that they are created by breaking down a large and complex application into smaller and simpler pieces that can be developed, deployed, and scaled independently.Microservices are scalable and resilient, meaning that they can handle variable workloads and recover from failures without affecting the whole application. Therefore, the correct statements are A and C, while B and D are incorrect.

Select the best option below to complete the following sentence. Multi-tenancy network connectivity provides dedicated resources through_____
Answer(s): B
Multi-tenancy network connectivity provides dedicated resources through network slicing. Network slicing is a technique that allows operators to create multiple logical networks over a shared physical infrastructure. Each network slice can have its own characteristics, such as bandwidth, latency, security, and quality of service, to meet the specific requirements of different applications and customers. Network slicing enables operators to offer customized and differentiated services to various tenants, such as enterprises, industries, and public sector organizations, while optimizing the utilization of network resources. Network slicing is one of the key features of 5G networks, as it supports the diverse and dynamic use cases of 5G, such as enhanced mobile broadband, massive machine-type communications, and ultra-reliable low-latency communications.

Select the best option below to complete the following sentence. The E2E Orchestrator for VMs is the same as_____for containers.
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.

What is the primary benefit of an Edge Cloud?
Answer(s): 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.

What are the main parameters of policy-based auto-scaling? (Select 2)
Answer(s): A,B
The main parameters of policy-based auto-scaling are threshold and min/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.
