Consider the following situation:
Process 1 (P1): May request up to 5 s_1 resources and 2 s_2 resources.
Process 2 (P2): May request up to 5 s_1 resources and 1 s_2 resources.
s_1 is initialized to 8 s_1 resources and s_2 has 2 resources.

Suppose the current situation is that P1 has 2 s_1 resources and 1 s_2 resources while P2 has 2 s_1 resources and 0 s_2 resources.

Which of the following statements are true. Multiple answers are allowed. Suppose the system uses deadlock avoidance policies.
Note: Incorrect answers give negative points while correct answers give positive points; if you select all answers you will get 0 out of 2.

 Suppose the current situation is that P1 has 2 s_1 resources and 1 s_2 resources while P2 has 2 s_1 resources and 0 s_2 resources. 
 
 Which of the following statements are true. Multiple answers are allowed. Suppose the system uses deadlock avoidance policies. 
 Note: Incorrect answers give negative points while correct answers give positive points; if you select all answers you will get 0 out of 2.

Answer

A request from P2 for 1 s_1 resources and 1 s_2 resource would be allowed.

Answer

A request from P1 for 3 s_1 resources would be allowed.

Answer
