What this domain covers

What to know about Multi Cloud And Hybrid Network Security Architecture

A candidate must design routing and firewall placement so all inter-spoke, cross-project, and hybrid traffic is forced through VM-Series instances. The single most important thing is correct route table and peering configuration, because inspection only happens when traffic is explicitly directed to the firewall.

Azure hub-and-spoke VNet peering with user-defined routes forcing spoke traffic through VM-Series

GCP Shared VPC host project deployment of VM-Series for centralized inspection across service projects

AWS Transit Gateway and Azure Virtual WAN attachment for hybrid inspection of on-premises traffic

Supported private cloud hypervisors for VM-Series, including VMware ESXi and KVM-based platforms

Watch out for

Common Multi Cloud And Hybrid Network Security Architecture exam traps

  • ▸Assuming spoke-to-spoke traffic is inspected by default in Azure; without UDRs and proper peering, traffic bypasses the firewall entirely.
  • ▸Deploying VM-Series in a GCP service project instead of the Shared VPC host project, so cross-project traffic is not centrally inspected.
  • ▸Treating AWS Transit Gateway or Azure Virtual WAN as inspection points; security inspection requires explicit firewall attachment and routing.
