Associate DRG-RT-A with the VCN-A attachment.<br \/>Associate DRG-RT-B (containing no routes for 192.168.1.0\/24) with the VCN-B attachment.<\/span><\/label><\/div>\n<\/div><div class='show-question-feedback' style='display:none;'>* Objective: Allow VCN-A to access on-premises (192.168.1.0\/24) via VPN, isolate VCN-B using DRG route tables effectively and securely.<br\/>* Option A: Single route table for both VCNs with NSGs on VCN-B to block traffic. This works but relies on NSGs, which are secondary to routing. Routing-level isolation is more secure and efficient.<br\/>* Option B: Single route table for VCN-A with the VPN route, default table (no VPN route) for VCN-B.<br\/>This isolates VCN-B effectively at the routing level, but managing one table across all attachments can complicate scaling.<br\/>* Option C: Two route tables, both with VPN routes, then blocking VCN-B with security lists. This is inefficient-routes are advertised unnecessarily, relying on security lists instead of routing isolation.<br\/>* Option D: Two route tables-DRG-RT-A with VPN route for VCN-A, DRG-RT-B with no VPN route for VCN-B. This ensures VCN-B has no path to on-premises at the DRG level, providing the strongest isolation.<br\/>* Conclusion: Option D is the most effective and secure, leveraging routing for isolation rather than secondary security controls.<br\/>Oracle documentation states:<br\/>* &#8220;DRG route tables control traffic between VCN attachments and external connections (e.g., VPN).<br\/>Associate a unique route table with each attachment to enforce specific routing policies.&#8221;<br\/>* &#8220;To isolate a VCN, ensure its DRG route table contains no routes to the destination.&#8221;Option D aligns with this approach.
