Question

You are troubleshooting a network issue a user is having. after having changed his network adapter to static addressing, he can no longer reach the internet. however, the machine resolves internet names to ip addresses. observe the adapter's configuration below, and determine the problem. ip address: 172.31.20.103 subnet: 255.255.255.0 dns server: 172.31.20.251 gateway address: 172.31.19.254

Answer 1

The gateway is on a different network. The user and the DNS are on the 172.31.20.0/24 network and the gateway is on the 172.31.19.0/24 net. It's impossible to work with these settings.
