Question 5/52
In a multi-region OCI environment, which configuration is necessary to allow communication between two VCNs located in different regions through a DRG?
Correct Answer: C
* Requirement: Private communication between VCNs in different OCI regions via DRG.
* Option A: LPGs are for same-region VCN peering, not cross-region-incorrect.
* Option B: Service Gateways are for OCI service access, not VCN-to-VCN routing-incorrect.
* Option C: Attaching both VCNs to a single DRG (via Remote Peering Connections implicitly) and configuring route tables enables cross-region communication over OCI's backbone. This is the standard approach.
* Option D: Internet Gateways use public IPs, which is insecure and not private-incorrect.
* Conclusion: Option C is the necessary configuration for DRG-based cross-region connectivity.
Oracle documentation confirms:
* "To connect VCNs in different regions, attach each to a DRG using Remote Peering Connections (RPCs). Configure DRG route tables to route traffic between VCN CIDRs."Option C reflects this setup (RPCs are implied). Reference:VCN Peering Overview - Oracle Help Center(docs.oracle.com/en-us/iaas
/Content/Network/Tasks/remoteVCNpeering.htm).
