Question 31 1 pts Three periodic processes with the following characteristics are to be scheduled. Determine the CPU utilization and whether a feasible schedule exists. Process Period Total CPU Lime p1 5 1 p2 10 3 p3 4 2 06/19, Yes 19/6, No 1.0. Yes 0 1.0. No Question 68 1 pts Processes p1 and p2 execute on a system with a single CPU and 2 identical I/O devices. Each process executes a compute-bound phase followed by an I/O-bound phase. The following table shows the lengths of each phase. Process Compute-bound phase V/O-bound phase p1 20 40 p2 10 70 p1 starts first at time 0. Without multiprogramming, at what time does the processing of p1 and p2 completely finish? 140 120 110 0 130 Question 69 1 pts Given the three processes and the respective arrival times, and total CPU times shown in the table below, using SRT scheduling, what is the start time for p2? Process Arrival time Total CPU time Start time End time p1 0 6 p2 1 4 ? p3 3 2 2 05 1
