The desk that can't leave its LAN
PC1 pings the desk next to it but never reaches the server. Find the missing setting and get it online.
The ticket
"I can print to the shared desk next to me, but the server has been unreachable all morning. My colleague on the same switch is fine." — the user at PC1
Your goal: Make PC1 ping the Server (10.10.10.10).

The network you're handed
- R1 — a router, the office router
- SW1 — a switch, the office access switch
- PC1 — a pc, the desk that can't reach the server
- PC2 — a pc, a colleague's desk that works
- Server — a server, the intranet server
It is already cabled and configured, and something in it is wrong. Nothing on this page tells you what — find it the way an engineer would, with show commands, ping and ipconfig in the industry-standard CLI.
How it's scored
- The grader checks the real network, not your commands: the simulator runs the actual pings and reads the actual tables. It passes the moment every check holds.
- One star for fixing it, one for beating the par time of 2:30, one for using 6 commands or fewer.
- A quick fix that breaks something else doesn't count — the checks also watch what must stay working (or stay blocked).
- Your copy of the network is private to your browser. Share your score and a friend gets their own fresh copy.
