Who it is for

People studying for CompTIA Network+ N10-009 on their own who learn best by seeing how topics connect, and who want one place to read the map, recall it with flashcards, prove it on practice questions and see their progress on a Treemap.

Who it is not for

It is not a hands-on lab, not a full video course and not a replacement for practising on real equipment or software.

Sample flashcard

When troubleshooting with the OSI model, in which direction do you work when nothing on a host works, and in which when only one application fails?

Bottom-up (start at layer 1) when nothing works; top-down when a single application fails. The first layer that checks out wrong is where to fix.

Sample practice question

A user at Harrowgate Surveying says nothing on her desktop works: no web, no mail, no file shares. The switch port she connects to shows its link light on at 1 Gbps, the port is in the correct access VLAN, and her MAC address appears in the switch's MAC table on that port. Following a bottom-up approach, what should the technician check NEXT?

• A. Whether the patch cable is crimped correctly
• B. Her IP address, subnet mask and default gateway
• C. Whether the browser trusts the site's certificate
• D. Whether the mail server answers on its TCP port

Answer: B. Link light, speed, VLAN membership and a learned MAC address show that layers 1 and 2 are working, so the next layer up is layer 3: addressing, mask, gateway and routes. The cable crimp is a layer 1 check that the link light already passed. Testing a service port is a layer 4 step and certificate trust is an upper-layer check, both of which come after basic IP connectivity is confirmed.
