In a hybrid cloud migration, which OCI component is essential for dynamically routing traffic between on-premises networks and OCI Virtual Cloud Networks (VCNs), facilitating seamless communication?

Objective: Identify the OCI component for dynamic routing in a hybrid setup.
Option A: Internet Gateway enables public internet access, not private hybrid routing—incorrect.
Option B: DRG is a virtual router that dynamically routes traffic between on-premises networks and VCNs via FastConnect or VPN, using protocols like BGP—correct.
Option C: Service Gateway provides private access to OCI services, not on-premises connectivity— incorrect.
Option D: LPG peers VCNs within the same region, not with on-premises—incorrect. Conclusion: DRG is essential for hybrid dynamic routing. Oracle documentation confirms: "The Dynamic Routing Gateway (DRG) enables dynamic routing between your on-premises network and VCNs, supporting hybrid cloud connectivity via FastConnect or VPN." This validates Option B. Reference: Dynamic Routing Gateway Overview - Oracle Help Center (docs.oracle.com/en-us/iaas/Content/Network/Tasks/managingDRGs.htm).
