Overview
Module: Module 1: Infrastructure & Addressing
Activity type: Quiz / retrieval practice
Target: ≥80% before topic mastery unlock
Objective: Given a host and a guest requirement, the learner can choose Type 1 vs Type 2 virtualization, create a working Linux guest (VirtualBox or Proxmox), and prove networking, DNS, and SSH with recorded evidence.

Instructions
In plain words: This is the teaching core. One major concept (or a tight group). Read carefully.
More detail: Use What this means under dense blocks.
Close the reading. Write answers from memory. Then self-score.

- In plain words, what is a virtual machine?
- What is the difference between a host and a guest?
- How does a Type 2 hypervisor differ from a Type 1 hypervisor?
- Which guest type normally has its own kernel: VM or LXC?
- What does
vmbr0behave like on Proxmox? - Why is a successful ping to
1.1.1.1but failed hostname lookup useful? - Why does this course put Docker in a Linux VM instead of nesting it in LXC on day one?
- Name one benefit and one risk of bridged networking versus NAT.
- What problem do snapshots solve that “just reinstall” is too slow for?
In plain words: Proxmox is a Type 1 hypervisor you install on dedicated hardware and manage in a web browser.

After scoring
In plain words: Read this block, then try the next action. If you feel stuck, tap What this means.
- Missed items → return to Reading weak sections → redo Feynman Retry → reattempt missed questions.
- Passing score unlocks marking this topic complete on the module hub (still need lab gate + homework).
In plain words: Big idea: - Missed items → return to **Reading** weak sections → redo **Feynman Retry** → reattempt missed questions.
