Oracle documents multiple Azure network patterns for application connectivity to Oracle AI Database@Azure, including VNet peering and Hub-and-Spoke VNet peering .

VNet peering enables application workloads in one Azure VNet to communicate privately with Oracle database resources exposed through a delegated subnet in another VNet. This is appropriate when relatively direct, low-latency communication is required.

A Hub-and-Spoke design introduces a central hub containing shared connectivity and security services, such as Azure Firewall, a Network Virtual Appliance, ExpressRoute gateway, or VPN gateway. Application and database VNets connect as spokes or workload/data networks, allowing centralized inspection and hybrid connectivity.

Oracle's documented topology set also includes local VNet, global connectivity, on-premises Hub-and-Spoke, and related enterprise designs. A point-to-site VPN client model is not identified as the standard application topology requested here. More fundamentally, an Oracle AI Database@Azure deployment cannot exist without an Azure VNet and delegated networking.

Therefore, the correct selections are B and C .
