📝 Sample Questions

Q1. What is the primary objective of load balancing on an SMP system?

🔹 A. To increase the clock speed of each processor

🔹 B. To ensure all processors have an equal share of the workload

🔹 C. To reduce the total number of context switches

🔹 D. To allocate more memory to heavily loaded processors

💡 Difficulty: easy | ✅ Correct: B

Q2. If a processor becomes idle on a system with a common run queue, what is its next action?

🔹 A. It signals the OS to perform push migration

🔹 B. It attempts to enter a low-power state

🔹 C. It immediately extracts a runnable process from the common queue

🔹 D. It waits for a pull migration request

💡 Difficulty: medium | ✅ Correct: C

Q3. In a heavily loaded system with private run queues, what is the primary advantage of using both push and pull migration together over using only one method?

🔹 A. It reduces the total memory required for process queues

🔹 B. It provides a more robust and responsive balancing mechanism

🔹 C. It simplifies the operating system's scheduling code

🔹 D. It eliminates the need for a common run queue

💡 Difficulty: hard | ✅ Correct: B
