BL0-220 Exam Dumps : Nokia Bell Labs Distributed Cloud Networks

The two main options to interconnect private and public clouds are VPN and WAN. VPN stands for Virtual Private Network, which is a secure and encrypted connection between two or more networks over the public internet. VPN allows private and public clouds to communicate with each other without exposing their data or traffic to third parties. WAN stands for Wide Area Network, which is a network that spans a large geographic area, such as a country or a continent. WAN allows private and public clouds to interconnect across different regions or locations, using high-speed and high-capacity links. Both VPN and WAN provide reliable, scalable, and flexible solutions for hybrid cloud scenarios, where private and public clouds work together to deliver optimal performance and efficiency. References: Nokia Bell Labs 5G Professional Certification - Distributed Cloud Networks, Cloud Data Center Interconnect for Large Enterprises, 5G Core on cloud: go public, private or a bit of both?

Software as a Service (SaaS) is a cloud computing offering that provides users with access to a vendor's cloud-based software. Users do not install applications on their local devices. Instead, the applications reside on a remote cloud network accessed through the web or an API. Within this context, Database-as-a-Service (DBaaS) is considered a form of SaaS, where the service provider manages the database's installation, maintenance, backup, and scaling needs on behalf of the customer. Platform-as-a-Service (PaaS) provides a platform allowing customers to develop, run, and manage applications without dealing with the complexity of building and maintaining the infrastructure typically associated with developing and launching an app. PaaS can include various software components, including database management systems, and thus can be considered a subset of SaaS.

Single and consistent point of management. Comprehensive Explanation and References of Correct Answer: Network Function Management provides different network slices for different companies and a single and consistent point of management. Network slicing is a technique that allows the creation of multiple logical networks on top of a shared physical infrastructure1. Each network slice can have its own characteristics, requirements, and services, tailored to the needs of different customers or applications1. Network Function Management is a component that handles the configuration, monitoring, and optimization of the network functions that compose each network slice2. It provides a single and consistent point of management for the network functions, regardless of their location, type, or vendor2. Multiple Orchestrators required for deployments is not a correct option. An Orchestrator is a component that coordinates the allocation and release of resources for network services and network slices3. There are different types of Orchestrators, such as NFV Orchestrator, NS Orchestrator, and Slice Orchestrator, but they are not part of the Network Function Management3. References: 1: Nokia Bell Labs Distributed Cloud Networks, Unit 5: New Services Automation, Section 5.1: Network Slicing 2: Nokia Bell Labs Distributed Cloud Networks, Unit 5: New Services Automation, Section 5.2: Network Function Management 3: Nokia Bell Labs Distributed Cloud Networks, Unit 5: New Services Automation, Section 5.3: Orchestration
