A PC can ping other hosts on its own subnet by address, and it cannot ping a host on the far side of the router. The default gateway field is blank. Which setting is missing?
Select an answer to reveal the explanation.
Short Explanation
The PC can talk to its neighbors and has no address for the door that leads out. You fill in the default gateway. The mask is already doing its local job, a name server is not required for an address ping, and a new adapter is not what the blank field is asking for.
Full Explanation
The default gateway is the router address a host uses for destinations that are not on its own subnet. This PC can ping its subnet, so the mask and the local link work, and the gateway field is blank, so the missing setting is the gateway. The mask is not missing. Local pings would fail if it were wrong enough to hide the neighbors. DNS resolves names. A ping by address does not need it, and a missing DNS server would not be fixed by typing a gateway. A new network adapter does not type an address into the gateway field. Exam caveat: the gateway you type has to be the router on this subnet. An address that is not local will not be used. Operational check: enter the router address, ping a host beyond it, and confirm the local pings still work. Ping a host beyond the router by address after the gateway is typed, and confirm local pings still work. Record the result on the ticket before you close the call. Write the gateway next to the address and the mask so the three settings agree.
