Optional concept notes
Mesh topology
Provides multiple paths by interconnecting nodes with several peers.
Star topology
Connects endpoints through a central network device.
Spine-and-leaf
Connects every leaf switch to every spine switch.

Spine-and-leaf
The core idea stays the same. The surrounding objective changes the evidence, decision, or task the exam asks for.
Three-tier architecture
Separates access distribution and core network functions.

Complete one provider lesson, then answer four related questions. That is enough for today; more practice is optional.
Your lesson stays open here while the provider opens in another tab. Choose one source; the notes above are optional.
Practice the reasoning here
Sketch a small network or packet path. Predict the expected state, introduce one fault, and identify the observation that isolates it.
- State the expected result before changing or testing anything.
- Name the observation, command, log, or report that would confirm it.
- Explain why the closest alternative does not fit the same requirement.
Check the whole objective
This unlocks objective 1.6 for recall. The latest checkpoint needs 70% or higher; a lower result puts the lesson back near the front of your timeline.
