Actual exam question for Oracle's 1Z0-1124-25 exam

Question #: 8
Topic #: 2

In a multi-region OCI environment, which configuration is necessary to allow communication between two VCNs located in different regions through a DRG?

AAttaching an LPG to each VCN and configuring route tables to peer them directly.

BAttaching a Service Gateway to each VCN and enabling transitive routing.

CAttaching each VCN to the same DRG and configuring the appropriate route tables on the DRG.

DConfiguring Internet Gateways on each VCN and using public IP addresses for communication.

Show Suggested Answer

Suggested 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).
