Which statement about the deployment of the Security Fabric in a multi-VDOM environment is true?

In a multi-VDOM (Virtual Domain) environment, the accurate statement regarding the deployment of the Security Fabric is that VDOMs without ports with connected devices are not displayed in the topology. This is because the Security Fabric topology is designed to show the various devices and connections that are actively involved in the security posture of the network. VDOMs that do not have any interfaces or ports linked to devices are not contributing to the overall network topology and thus are not shown. This approach helps simplify the visualization of the network's security landscape, focusing on the elements that are actually communicating and requiring monitoring.

The other statements do not hold true within the context of VDOM deployments. For instance, the idea that all VDOMs appear on the topology would clutter the view with inactive components, while suggesting that additional licensing is needed to display VDOMs fails to recognize that the ability to visualize is typically part of the standard capabilities of FortiGate with VDOMs. Lastly, the notion that VDOMs can only communicate via a direct link misrepresents the more flexible communication methodologies available within Fortinet’s architecture, which may include methods such as through shared resources or other configurational capabilities.
