Refer to the exhibits.

The correct answer is B. The LAN address object shown in the exhibit has a default value of 10.0.0.0/255.255.255.0, and it has per-device mappings only for BR1-FGT-1, HQ-NGFW-1, and Local-Firewall. There is no per-device mapping entry for Remote-Firewall.

The FortiManager 7.6 Administrator Study Guide gives the exact rule for this behavior: “The devices in the ADOM that do not have a dynamic mapping for LAN have a default value”. The same page also explains that dynamic objects let you map one logical object to unique values per device, but devices without a mapping use the object’s default definition.

Since Remote-Firewall is not listed in the Per-Device Mapping table, it inherits the default LAN value: 10.0.0.0/255.255.255.0.
