問題文
The collected records show one outbound connection to an address never seen before, and the host side shows a new file written one second earlier. What does putting the two together support?
選択肢
- That something was moved out of the estate, because a connection outward is how material leaves and the file is what was copied.
- That the host was reached from the outside, because the file is what the visitor left and the connection is how the visitor arrived.
- That something was fetched into the estate from outside, because the order of the two observations fits a transfer inward.
- That the two observations are unrelated, because an address that has not been seen before appears on any busy day in numbers.
