A multilevel page table is preferred in comparison to a single level page table for translating virtual address to physical address because

1. it reduces the memory access time to read or write a memory location
2. it helps to reduce the size of page table needed to implement the virtual address space of a process
3. it is required by the translation look-aside buffer
4. it helps to reduce the number of page faults in page replacement algorithms

As we know that the use of multilevel page table reduces the size of the page table needed to implement the virtual address space of a process.
