Answer these 3 question

QUESTION 3

Suppose we have four objects O1, O2, O3, and O4. Suppose we have two subjects S1 and S2. Finally, suppose we have two integrity levels, L and H, where L < = H The integrity levels associated with the objects and subjects is as follows: il(O1) = L, il(O2) = H, il(O3) = L, il(O4) = H, il(S1) = L, il(S2) = H. Select all the objects S1 can modify that satisfy strict integrity.

A.O1 B.O2 C. O3 D.O4

QUESTION 5

Suppose we have four objects O1, O2, O3, and O4. Suppose we have two subjects S1 and S2. Finally, suppose we have two integrity levels, L and H, where L <= H. The integrity levels associated with the objects and subjects is as follows: il(O1) = L, il(O2) = H, il(O3) = L, il(O4) = H, il(S1) = L, il(S2) = H. What transfer path exists from O4 to O1 that satisfy strict integrity?

A. None B. O4 to S1 to O1 C. O4 to S2 to O1
