Optional concept notes
Physical network diagram
Shows device locations, cable paths, ports, and physical connections.
Logical network diagram
Shows addressing, VLANs, routing, and logical traffic relationships.
IP address management
Tracks subnets, address assignments, reservations, and available address space.
Golden configuration
Provides an approved known-good baseline for network devices.
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 3.1 for recall. The latest checkpoint needs 70% or higher; a lower result puts the lesson back near the front of your timeline.
