Are OCI subnets tied to Availability Domains?

In Oracle Cloud Infrastructure (OCI), subnets are designed to be associated with a Virtual Cloud Network (VCN) and can span multiple availability domains (ADs) within a region. Each subnet can support resources that may reside in different availability domains but remains logically isolated within a VCN.

The important aspect to understand is that while availability domains can provide resilience and high availability for applications by ensuring resources are spread across different physical data centers, subnets themselves are not strictly tied to a single availability domain. Instead, they provide a way to group resources based on connectivity and security requirements within the broader VCN.

Additionally, since subnets can be deployed in different availability domains, a well-architected setup in OCI allows users to design their network architecture to leverage the availability of different ADs while still benefiting from a single subnet configuration.

Therefore, stating that OCI subnets are tied to availability domains is incorrect, which supports the reasoning behind selecting "False" as the correct answer.
