Which two are required to enable central management on FortiSASE?

According to the FortiOS Administration Guide, when configuring central management, a FortiManager Cloud entitlement must be present and the devices must share the same FortiCloud account for registration. Specifically:

“The FortiManager Cloud button can only be selected if you have a FortiManager Cloud product entitlement.”

“The FortiGate and FortiCloud license are registered to the same account.”

Thus, the two verified requirements are: B (entitlement) and D (same FortiCloud account).
