What service is required to create an OAC instance?

The correct choice indicates that the OAC service itself is required to create an OAC (Oracle Analytics Cloud) instance. When setting up an instance, the specific service you need to utilize is OAC, as this cloud service provides the environment and infrastructure necessary to deploy and manage analytics applications and data visualizations.

Selecting the OAC service allows users to leverage the features and functionality specifically designed for data analytics, including tools for data modeling, preparation, visualization, and collaboration. Other services, such as Autonomous Data Warehouse (ADW) or Oracle Cloud Platform (OCP), serve different purposes within the Oracle Cloud ecosystem and are not directly responsible for creating an OAC instance. Therefore, understanding the distinct roles of various Oracle services is essential for accurately setting up an analytics environment.
