Question 15

An enterprise has multiple VCNs peered to a central hub VCN using a DRG. A security auditor notes that Vcn-A can communicate with Vcn-C because transit routing is enabled on the DRG. The security policy dictates that Vcn-A must never communicate with Vcn-C. How can you block this specific inter-VCN traffic while keeping other routes intact?

Accepted Answer

Modify the DRG route tables and import/export route distributions to prevent Vcn-A and Vcn-C from exchanging routes.. In DRG version 2, you can create custom DRG route tables and fine-tune import/export route distributions to prevent specific attachments from learning each other's routes, thereby blocking unwanted transit paths.

Answer

Attach a NAT Gateway to the hub VCN.

Answer

Delete the Internet Gateway from Vcn-A.

Answer

Change the subnet CIDR of Vcn-C so it no longer overlaps.
