The question can no longer be answered in 2022 because A,B and D are not correct. Page 42. NSE7 6.4: FortiOS is a 64-bit architecture, therefore the kernel doesn't need to use memory paging to access the whole memory space. All the memory space is directly accessible by the kernel. diagnose hardware sysinfo memory no longer displays LowTotal / LowFree. - lummi
