Scenario

A Linux server cannot reach the internet. Use the terminal commands to investigate the network configuration and diagnose the problem.

Terminal
Linux 5.15.0-91-generic #101-Ubuntu
Welcome to Ubuntu 22.04.3 LTS
user@server:~$

Answer the following based on what you observed:

1. Based on the output of 'ip route', what is the primary cause of the internet connectivity failure?

2. What command would fix the missing default gateway? (gateway IP is 192.168.1.1)

3. The server can ping 192.168.1.1 but cannot resolve 'google.com'. What additional issue needs to be fixed?
