Which of the following is NOT a core service category in OCI?

The correct choice identifies that marketing is not a core service category in Oracle Cloud Infrastructure (OCI). In OCI, core service categories include Compute, Storage, and Networking, which are fundamental components for enabling cloud infrastructure solutions. Each of these categories plays a vital role in providing the necessary resources for deploying applications and managing data.

Compute services allow users to run applications and workloads on virtual machines and bare metal servers, while Storage services provide solutions for object, block, and file storage to meet various data management needs. Networking services facilitate connectivity between different resources and services in the cloud, ensuring effective data transmission and communication.

In contrast, marketing is not related to the infrastructure services or functionalities that OCI offers. It pertains more to business strategies and practices to promote products and services rather than cloud infrastructure solutions. Therefore, it stands out as not belonging to the core service categories within OCI.
