Which statements are true about a Virtual Cloud Network (VCN)? (Choose three)

A Virtual Cloud Network (VCN) is indeed a software or virtual version of a traditional network, which allows users to create their own private network in the cloud. This virtual network provides the same functionalities and capabilities as a traditional on-premises network, enabling users to manage various network resources, such as IP addresses, route tables, and gateways. This virtualization aspect facilitates the flexibility and scalability that cloud environments offer.

Furthermore, a VCN can also connect to another VCN, enhancing connectivity options and allowing for inter-VCN communication while maintaining network isolation. This is particularly valuable when organizations have separate applications or services needing to communicate securely across different networks.

While subnets help organize the network, they must reside within the same Availability Domain in a particular region. This limitation means that a VCN cannot have subnets spanning multiple Availability Domains. However, a VCN itself can exist within a singular region, maintaining resource isolation and management boundaries.

Understanding these features of VCNs underscores their role in cloud architecture, enabling effective network design and implementation in Oracle Cloud Infrastructure.
