📝 Sample Questions

Q1. A driver’s ISR queues a work item to the system’s thread pool. Which of the following best describes why using a thread‑pool worker thread is preferred over creating a new thread for each work item?

🔹 A. It guarantees the work runs at the highest interrupt priority.
🔹 B. It reduces overhead by reusing existing threads and avoids excessive context switches.
🔹 C. It allows the work to execute in user mode without kernel mediation.
🔹 D. It ensures the work item runs only when the CPU is idle.

💡 Difficulty: easy | ✅ Correct: A

Q2. How does the priority relationship between Deferred Procedure Calls (DPCs) and thread‑pool work items affect the latency of I/O completion notifications?

🔹 A. DPCs run at a lower priority than thread‑pool work items, increasing latency.
🔹 B. DPCs run at a higher priority, so they pre‑empt thread‑pool work items, reducing latency.
🔹 C. Both run at the same priority, so latency is unaffected.
🔹 D. Thread‑pool work items always run before DPCs, eliminating latency.

💡 Difficulty: medium | ✅ Correct: A

Q3. A multimedia application queues 200 short‑duration tasks to the thread pool, but the default pool size is only 8 threads. Which strategy will most likely keep frame rendering smooth while still processing all tasks?

🔹 A. Manually create additional threads equal to the number of tasks.
🔹 B. Increase the thread‑pool minimum size to 50 threads.
🔹 C. Use a bounded queue that limits tasks to the current pool size and process excess tasks on the calling thread.
🔹 D. Leave the pool unchanged and accept occasional frame drops.

💡 Difficulty: hard | ✅ Correct: B
