CompTIA Linux+ XK0-006 (V8) Practice Question

A Linux administrator receives complaints that a web server with two NICs cannot reach any public Internet hosts, but it can still communicate with systems on the company's internal 10.10.0.0/16 network. The current IPv4 routing table is:

$ ip route
default via 10.10.0.1 dev eth0 proto dhcp metric 100
10.10.0.0/16 dev eth0  proto kernel  scope link  src 10.10.0.50
192.168.50.0/24 dev eth1  proto kernel  scope link  src 192.168.50.10

Corporate firewalls are configured to allow outbound traffic only from the 192.168.50.0/24 segment, and the correct gateway for that network is 192.168.50.1. Which command will most effectively restore Internet connectivity while leaving the existing internal routes intact?

  • ip route add default via 192.168.50.1 dev eth1 metric 10

  • ip addr add 192.168.50.1/24 dev eth1

  • ip route del default via 10.10.0.1 && ip route add default via 192.168.50.1 dev eth1 metric 10

  • echo "GATEWAY=192.168.50.1" >> /etc/sysconfig/network
