(A) To ignore task priorities (B) To measure average CPU idle time only (C) To reduce memory usage (D) To determine if all periodic tasks can meet their deadlines under fixed-priority scheduling 2. Which scheduling algorithm is commonly analyzed using utilization bound tests? (A) Batch processing (B) Earliest Deadline First (EDF) only (C) Round-robin scheduling (D) Rate Monotonic Scheduling (RMS) 3. In the utilization bound test,UU represents: (A) Task period only (B) Total CPU utilization by all tasks (C) CPU idle time (D) Disk usage 4. For RMS, ifU≤n(21/n−1)U≤n(21/n−1), then: (A) Task periods are ignored (B) All tasks are guaranteed to meet their deadlines (C) CPU idle time is maximized (D) Deadlines may be missed randomly 5. Utilization bound tests are suitable for: (A) Fixed-priority periodic task systems (B) Soft real-time tasks only (C) Aperiodic tasks exclusively (D) Non-preemptive batch jobs 6. If the total utilization exceeds the bound in RMS, then: (A) CPU idle time increases automatically (B) All deadlines are still met (C) Task deadlines are not guaranteed (D) Tasks are ignored 7. Which is a limitation of the utilization bound test? (A) It reduces memory usage automatically (B) It predicts exact response times (C) It is sufficient but not necessary; tasks may still be schedulable above the bound (D) It works for EDF only 8. The utilization bound test becomes more accurate as: (A) Disk I/O decreases (B) CPU speed decreases (C) Task periods increase only (D) Task set size increases 9. Which task parameter is essential in computing CPU utilization for the bound test? (A) CPU idle time only (B) Task name (C) Disk usage (D) WCET (Worst-Case Execution Time) 10. #13: The total CPU utilizationUU is: (A) CPU idle cycles (B) WCET of the first task only (C) Sum of utilizations of all periodic tasks (D) Disk usage 11. Which of the following is TRUE about utilization bound tests? (A) It gives exact response times (B) It provides a quick sufficient test for schedulability (C) It is used for memory allocation (D) It ignores task deadlines 12. Utilization bound tests cannot be used for: (A) Aperiodic tasks with irregular arrivals (B) Fixed-priority periodic tasks (C) Hard real-time periodic tasks (D) Preemptive scheduling systems 13. Which of the following increases the CPU utilization for the test? (A) Longer idle time (B) Larger task periods (C) Higher WCET relative to period (D) Fewer tasks only 14. Utilization bound tests are considered: (A) Sufficient but not necessary conditions (B) Necessary only (C) Both necessary and sufficient for all task sets (D) Only for EDF scheduling 15. Which factor does NOT affect utilization bound in RMS? (A) Task deadlines less than or equal to periods (B) WCET values (C) CPU idle cycles (D) Task periods 16. The main advantage of the utilization bound test is: (A) Reduces WCET automatically (B) Calculates exact response times for all tasks (C) Quick and simple method to verify schedulability of fixed-priority tasks (D) Allocates memory efficiently Related Posts:Power distribution and utilization solved MCQs with answerElectrical Energy Utilization — MCQs – EEEnglish MCQs for Competitive exams and testsChemistry MCQs for Competitive exams and testsPediatrics MCQs - Interviews Questions Answers for Jobs TestsTests on Construction Materials MCQs - Civil
