What is the primary purpose of a Virtual Cloud Network (VCN)?

The primary purpose of a Virtual Cloud Network (VCN) is network isolation and segmentation. A VCN functions as a private network in the cloud, which allows you to define and control the network environment for your cloud resources. This includes the ability to create subnets, route tables, and security lists that manage traffic flow and access controls.

By using a VCN, organizations can segregate their cloud resources, thereby enhancing security and improving management. For instance, different tiers of an application can reside in separate subnets within the VCN, allowing for tailored security configurations and making it easier to enforce policies and compliance measures.

This network isolation is crucial for maintaining data integrity, protecting sensitive information, and controlling who has access to different parts of the cloud infrastructure. It ensures that resources can communicate securely without exposure to the public internet or unwanted traffic, effectively helping to safeguard cloud workloads.

The other choices, while relevant to various aspects of cloud services, do not specifically encapsulate the essential role of a VCN. Data storage management focuses on how data is stored, network scalability emphasizes the ability to expand or contract network resources, and resource provisioning relates to the allocation of cloud resources like compute and storage, but these do not address the core function of a VCN
