Suppose the page table below is complete. Give an example of a logical address that would generate a page fault. Explain. (Remember from section 9.2 of the textbook that the valid/invalid flag refers to whether a given page is loaded in memory.)

Problem 6 (13 points) The page table below is for a system with 16-bit virtual as well as physical addresses and with 4,096-byte pages. The reference bit is set to 1 when the page has been referenced. Periodically, a thread zeroes out all values of the reference bit. A dash for a page frame indicates the page is not in memory.
