b. MakeFile

c. CreateFile

d. OpenInputFile 2

11. Which of the following is not one of the CreationDisposition parameter options required when creating a new file?

b. CREATE_ALWAYS

c. OPEN_ALWAYS

d. TRUNCATE_NEW

b. FILE_CURRENT

c. FILE_REVERSE

d. FILE_END

13. What happens when SetConsoleCursorPosition sets the cursor position to an area of the screen buffer that is not currently visible?

a. the cursor is not displayed

b. the console window is shifted to make the cursor visible

c. a runtime error results d. the cursor is moved to the upper-left corner of the visible window

14. In protected mode, how is a variable's offset translated into a linear address by the processor?

a. Uses the segment selector to look up the segment descriptor. Adds the segment's base address to the variable's offset.

b. Shifts the segment selector left 4 bits and adds the offset, producing a linear address.

c. Combines the value of the GDTR register with the segment selector in the logical address, and adds the segment base to the variable's offset.

d. Uses the LDTR register to locate the appropriate entry in the segment descriptor table, which contains the variable's linear address.

15. (True/False) When implementing paging, the processor uses a 10-bit directory field in the linear address. This directory field contains the base address of a page table. a. true b. false
