Question No. 1

In a cloud deployment, SaaS can stand for which of the following? (Select 2)

Show Answer Hide Answer
Correct Answer: B, D

Security as a Service and Software as a Service are two examples of SaaS in a cloud deployment. Security as a Service is a model where security services such as firewall, antivirus, encryption, etc.are delivered over the Internet by a cloud provider1. Software as a Service is a model where software applications such as email, CRM, ERP, etc.are hosted and managed by a cloud provider and accessed by users over the Internet2. Stack as a Service and Service as a Service are not valid terms for SaaS in a cloud deployment.Stack as a Service is a typo for Stack Overflow, a popular online platform for developers3.Service as a Service is a redundant and meaningless term that does not describe any cloud service model4.Reference:1: Nokia Bell Labs Distributed Cloud Networks, Unit 1: Cloud Ecosystem, Section 1.3: Cloud Service Models2: Nokia Bell Labs Distributed Cloud Networks, Unit 1: Cloud Ecosystem, Section 1.3: Cloud Service Models3:Stack Overflow4:What is Service as a Service (SaaS)?

SaaS within cloud computing primarily stands for Software as a Service, which delivers software applications over the internet on a subscription basis. It allows users to connect to and use cloud-based apps over the Internet, such as email, calendaring, and office tools (like Microsoft Office 365). Security as a Service (SECaaS) is an outsourcing model for security management. Typically, businesses utilize this service for functions like anti-virus software, intrusion detection, and authentication. SECaaS is also considered a type of SaaS where security services are delivered remotely via the internet. Therefore, both Software as a Service and Security as a Service are correct answers, emphasizing the diversity of services provided through the SaaS model beyond just software applications.


Question No. 2

In public networks, what are the parts of a distributed cloud used for the 5G Core control plane. (Select 2)

Show Answer Hide Answer
Correct Answer: A, B

The 5G Core control plane is responsible for managing the network functions, services, and resources, such as authentication, authorization, session management, policy control, mobility management, etc.1.The 5G Core control plane can be deployed in a distributed cloud architecture, which consists of different cloud layers that have different characteristics and roles2.The Metro Edge Cloud is a cloud layer that is located near the access network, and provides low latency, high bandwidth, and local processing for the control plane functions3.The Core/Central Cloud is a cloud layer that is located in the core network, and provides high availability, scalability, and security for the control plane functions4.The distributed cloud architecture enables the 5G Core control plane to optimize the network performance, efficiency, and flexibility, and to support various use cases and applications.Reference:1:Nokia Bell Labs Distributed Cloud Networks, Unit 1: Cloud Ecosystem, Section 1.2: Cloud Architecture2:Nokia Bell Labs Distributed Cloud Networks, Unit 1: Cloud Ecosystem, Section 1.3: Distributed Cloud3:Nokia Bell Labs Distributed Cloud Networks, Unit 3: Cloud Resource Planning, Section 3.2: Cloud Resource Planning for Distributed Cloud4:Nokia Bell Labs Distributed Cloud Networks, Unit 3: Cloud Resource Planning, Section 3.3: Cloud Resource Planning for Central Cloud :Nokia Bell Labs Distributed Cloud Networks, Unit 5: New Services Automation, Section 5.1: Distributed Cloud Services Automation


Question No. 3

Which one of the following requires a Network Service Descriptor defined in a catalog?

Show Answer Hide Answer
Correct Answer: B

A Network Service Descriptor (NSD) is a template that defines the characteristics and requirements of a network service, such as the number and type of virtual network functions (VNFs), the connectivity and topology between them, the scaling policies, and the service level agreements1.A NSD is defined in a catalog that is managed by the cloud orchestration layer, which is responsible for deploying, monitoring, and controlling the network services across the distributed cloud2.Therefore, cloud orchestration requires a NSD defined in a catalog, while the other options do not.Reference:1:Nokia Bell Labs Distributed Cloud Networks, Unit 3: Cloud Resource Planning, Topic: Network Service Descriptor Role2:Nokia Bell Labs Distributed Cloud Networks, Unit 4: Operating Your Cloud, Topic: Cloud Orchestration

A Network Service Descriptor (NSD) is an integral part of network function virtualization (NFV) architecture. It describes the composition of network services, including how different network functions are chained or combined to provide a specific service. Cloud orchestration involves the automated management of various cloud computing services and resources, including networking services. It requires a comprehensive description of these services (i.e., NSD) to automate their deployment, scaling, and management effectively. NSD in a catalog would be used to define the parameters and configurations needed for the orchestrated service to be deployed in a cloud environment, making cloud orchestration the most likely context for requiring an NSD.


Question No. 4

Which of the following statements are correct regarding the characteristics of microservices? (Select 2)

Show Answer Hide Answer
Correct Answer: 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 arechainedin 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 aredifferentiatedby function, meaning that each microservice has a single responsibility and performs a distinct function within the application.

Microservices arederivedfrom 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 arescalableandresilient, 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.Reference:1:Nokia Bell Labs Distributed Cloud Networks, Unit 2: Cloud Technologies and Features, Topic: Microservices and Containerization2:Module by Module - Self Study Note Guide, DC2.4-- Microservices and Containerization
