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

The statement that best describes cloud native operations is cloud native provides operation adaptability. Cloud native operations are based on the principles of agility, resilience, and automation, which enable the cloud to adapt to changing demands and conditions12. Cloud native is not only operational by AI, nor does it rely only on network automation. AI and automation are tools that enhance the cloud native operations, but they are not the only factors that define them12. Cloud native design does not limit scalability, but rather enables it by using microservices, containers, and orchestration12. References: 1: Nokia Bell Labs Distributed Cloud Networks, Unit 4: Operating Your Cloud, slide 6 2: Nokia Bell Labs 5G Certification Program - Blended Learning, Section 2: Distributed Cloud Networks, slide 16

A Policy Database is a key component in Closed Loop Automation. It stores the policies that govern the automated decision-making processes within a system. These policies define the actions to be taken in response to specific events or conditions, enabling the system to automatically adjust its operations without human intervention, thus increasing efficiency and responsiveness.

On-premise Edge Cloud and Metro Edge Cloud are the cloud deployments that provide the lowest latency. Latency is the time it takes for data to travel from the source to the destination1. On-premise Edge Cloud is a cloud deployment that is located within the premises of the end-user, such as a factory, a hospital, or a campus2. Metro Edge Cloud is a cloud deployment that is located within the same metropolitan area as the end-user, such as a city or a suburb3. Both On-premise Edge Cloud and Metro Edge Cloud reduce the distance and the number of hops that data has to travel, resulting in lower latency and higher performance4. Far Edge Cloud and Central Cloud are not the cloud deployments that provide the lowest latency. Far Edge Cloud is a cloud deployment that is located at the edge of the operator’s network, such as a regional data center or a base station3. Central Cloud is a cloud deployment that is located at the core of the operator’s network, such as a national data center or a cloud provider3. Both Far Edge Cloud and Central Cloud increase the distance and the number of hops that data has to travel, resulting in higher latency and lower performance4.
