Helping Hand Questions for BL0-220

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

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.
