In the X86-64 architecture, four levels of page mapping structures are used when page size is 4KB and page table entries are 8 bytes. The page map level 4 (PML4) table size is one page and it entries point to tables at the next level each of which is called a PDPT (page directory pointer table). Each PDPT table is also one page long.  What is the maximum amount of memory that could be required by PDPT tables?
