An organization has its IT infrastructure in a hybrid setup with an on-premises environment and an Oracle Cloud Infrastructure (OCI) Virtual Cloud Network (VCN) in the us-phoenix-1 region. The on-premises applications communicate with compute instances inside the VCN over a hardware VPN connection. They are looking to implement an Intrusion Detection and Prevention (IDS/IPS) system for their OCI environment. This platform should have the ability to scale to thousands of compute instances running inside the VCN. How should they architect their solution on OCI to achieve this goal? (Choose the best answer.)
