Assessment

1. What does booting Linux from RAM usually mean in this course? A. Deleting the bootloader B. Removing the kernel C. Using memory-backed boot or root filesystem patterns D. Making Linux run without hardware

2. What should happen before changing bootloader or initramfs behavior on a real system? A. Back up data and prepare a recovery plan B. Delete all old boot entries C. Disable all documentation D. Assume every distro works the same way

3. What role does initramfs play? A. It replaces all user applications B. It is a permanent home directory C. It is only used for web browsing D. It supports early boot before the final root filesystem is ready

4. What is a key property of RAM-backed or tmpfs-backed changes? A. They always survive power loss B. They are usually volatile unless persistence is designed C. They require no memory D. They automatically update the base system

5. In an overlay-style design, what does a writable tmpfs upper layer usually do? A. Permanently rewrites firmware B. Replaces the CPU C. Stores changes temporarily during the session D. Deletes the lower layer

6. Why must RAM sizing be tested? A. RAM use is unrelated to workloads B. Testing RAM is only for games C. RAM-backed systems cannot run applications D. The root image, overlay, cache, and applications all compete for memory

7. What is a good first environment for testing RAM-boot designs? A. A virtual machine, spare disk, or recoverable lab system B. A production laptop with no backup C. A remote server with no console access D. A primary workstation during a deadline

8. What is the best summary of a safe RAM-boot design routine? A. Guess, edit boot files, and hope B. Define the goal, choose a pattern, test safely, plan persistence, and document rollback C. Delete logs and remove recovery media D. Copy random commands without checking the distro
