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 3.2 for recall. The latest checkpoint needs 70% or higher; a lower result puts the lesson back near the front of your timeline.
