Which one of the following requires a Network Service Descriptor defined in a catalog?
Answer(s): 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.

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.
What are the three key drivers required for video-based service in on-premise cloud? (Select 3)
Answer(s): 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.

Which of the following are benefits of life cycle management?
Answer(s): C
All life cycle stages are clearly identified. Comprehensive Explanation and Reference ofAnswer; Life cycle management is the process of managing the Explanationdevelopment, deployment, operation, and decommissioning of cloud applications and services. It involves defining the requirements, design, testing, deployment, monitoring, scaling, updating, and retiring of cloud resources. One of the benefits of life cycle management is that it provides clarity and visibility into the different stages of the cloud service, from inception to termination. This helps to ensure quality, efficiency, security, and reliability of the cloud service, as well as to optimize the use of resources and reduce costs.

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

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.
Select the most appropriate word to complete the following sentence:The public cloud ecosystem is a great value for users that offers many more options and_____than the simple consumption of resources.
Answer(s): D
The most appropriate word to complete the sentence is benefits. 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.
