What purpose does an OCI Dynamic Routing Gateway serve?

A Dynamic Routing Gateway (DRG) is an essential component in Oracle Cloud Infrastructure that facilitates the connection between Oracle Cloud resources and on-premises environments or other cloud networks. Its primary purpose is to enable secure and reliable communication between these disparate networks. When you set up a DRG, you can establish a Virtual Cloud Network (VCN) with a connection to your on-premises data center or other networks using technologies such as FastConnect or a VPN. This capability streamlines data transfer and enhances integration between cloud and on-premises systems, allowing organizations to leverage both environments seamlessly.

The other options do not accurately represent the core function of a Dynamic Routing Gateway. For instance, while it is possible for a DRG to support traffic between different VCNs indirectly by facilitating networking connections, the primary role is not to connect VCNs within the same region. Handling traffic between different OCI services falls under the functions of the VCN itself, rather than being a specific responsibility of the DRG. Lastly, enhancing database performance is not a direct function of a DRG, but rather depends on factors like instances, storage, and configurations specific to database services. Thus, the role of the DRG is uniquely focused on enabling connectivity between Oracle cloud instances and
