Question #: 16
Topic #: 2
You have provisioned two VNets for Oracle AI Database@Azure in the same Oracle Availability Zone. One VNet uses advanced network features and the other uses default networking, and you now want to peer them. What should you expect?
A.
VNet peering between them isn't supported and may cause asymmetric routing and traffic loss.
B.
Peering will succeed with no additional configuration required.
C.
Peering will automatically upgrade the default-networking VNet.
D.
Peering will disable advanced network features on both VNets.
This configuration is explicitly identified as unsupported in Microsoft's Oracle AI Database@Azure network-planning guidance. If two Oracle AI Database@Azure VNets are deployed in the same Oracle Availability Zone and one uses Advanced Networking while the other uses the default networking implementation, VNet peering between them can introduce asymmetric routing .
Asymmetric routing occurs when outbound and return traffic traverse different network paths. This is particularly problematic with stateful network elements and the differing routing models associated with the two Oracle AI Database@Azure network implementations. The result can be data-plane traffic loss toward the VNet using Advanced Networking.
VNet peering itself does not upgrade a previously provisioned VNet to Advanced Networking, nor does it downgrade the Advanced Networking environment. Advanced Networking capability is determined by the feature configuration and the state of the delegated subnet before Oracle resources/VNICs are provisioned.
Therefore, the two environments should not be directly peered in this mismatched state. The correct answer is A .
