Q1. Why does Windows use a per‑working‑set least‑recently‑used (LRU) replacement policy instead of a global LRU?

🔹 A. Because per‑working‑set LRU reduces CPU overhead by limiting scans to each process.
🔹 B. Because a global LRU would require more disk space for page tables.
🔹 C. Because per‑working‑set LRU guarantees that all processes get equal memory.
🔹 D. Because a global LRU cannot track page references.

💡 Difficulty: easy | ✅ Correct: A

Q2. A process with a 200 MB working set receives a hard limit of 150 MB. During a period of high CPU activity, the VM manager must trim pages. Which action best follows the manager’s policy for trimming?

🔹 A. Trim the newest pages first until the working set is exactly 150 MB.
🔹 B. Remove the oldest unreferenced pages first, even if the set falls below 150 MB.

🔹 D. Trim pages only when physical memory is critically low.

💡 Difficulty: medium | ✅ Correct: B

🔹 A. Byte 0x00A3F5C0 in paging file 3.
🔹 B. Byte 0x00A3F5C0 in paging file 6.
