IoT, AI, Blockchain, and Analytics are emerging technologies enabled by the cloud. What are some of the attributes of cloud computing that enable these technologies?
Cloud resources scale up and down in response to the workload demand, with users paying only for resources that they use. This makes it cost-viable for organizations to leverage emerging technologies on the cloud./Emerging technologies such as IoT, AI, Blockchain, and Analytics process and generate an unprecedented amount of data. Cloud provides the scalability and processing power required to gather, store, and process this data.

Correct,
What are some of the benefits of using microservices architecture?
Each component can be scaled independently, reducing the waste and cost associated with having to scale entire applications./Microservices are function specific independent components that can be developed and updated by multiple developers working independently on the individual components.
Cloud native applications follow a consistent set of development principles. Identify two of these development principles from the provided options.
Each microservice in a cloud native application is packaged with its libraries and dependencies into individual containers.
What is File Storage sometimes called?
File Storage is mounted to compute nodes via an ethernet network and is sometimes referred to as 'Network File Storage' or NFS.
According to the IaaS video, which one of these is NOT a likely use case for IaaS?
For an organization looking for greater control over the configuration, management, workload availability, and performance of their infrastructure, it is unlikely that they would opt for IaaS.
What are the key elements of a Hybrid Multicloud strategy?
Hybrid Multicloud implies that you have the flexibility to work across cloud models and service providers without being locked-in to a specific vendor or model./Hybrid Multicloud strategy allows you to work across public and private clouds behaving as if they are part of the same infrastructure.
Which one of the provided options is true for Infrastructure-as-a-Service
In Infrastructure-as-a-Service, the cloud provider manages the data centers, cooling, power, networking, security, servers, and storage.
Which are some of the key components of cloud Infrastructure-as-a-Service?
