Overview
Module: Module 1: Infrastructure & Addressing
Activity type: Quiz / retrieval practice
Target: ≥80% before topic mastery unlock
Objective: Given two Compose services, the learner can place them on an isolated user-defined network, call one service by DNS name from the other, and explain host-port publish versus container-to-container traffic.

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.

- What does
localhostmean inside Sonarr's container? - Why is a user-defined bridge better than the legacy default for a Compose stack?
- Does container-to-container traffic require a published host port?
- When is overlay networking relevant?
- Why is host networking not a harmless troubleshooting switch?
In plain words: Bridged networking puts the guest on the real LAN with its own address, handy and less isolated.

- 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).
