What Does the "route add" Command Do in Network Configuration?

A network technician does not have access to the GUI of a server and needs to adjust some network properties.

Given the command: route add 0.0.0.0 mask 0.0.0.0 192.169.1.222 metric 1 Which of the following is the technician attempting to alter?

A.

The technician is clearing the route table.

B.

The technician is adding a static IP address.

C.

The technician is clearing the subnet mask setting.

D.

The technician is setting the default gateway.

D.

The command "route add 0.0.0.0 mask 0.0.0.0 192.168.1.222 metric 1" is used to add a default route to a server or a client machine. It specifies that all traffic with an unknown destination should be sent to the IP address 192.168.1.222, which is the default gateway.

The term "route" refers to the path that network traffic takes to reach its destination. A default route is a route that is used when there is no specific route available for a particular destination. In other words, if a device does not know where to send a particular packet, it will use the default route to send it to the default gateway, which will then forward it to its intended destination.

The "0.0.0.0" mask in the command indicates that the route applies to all possible destination IP addresses. The "metric 1" specifies the cost or priority of this route relative to other possible routes.

Therefore, option D, "The technician is setting the default gateway," is the correct answer to the question. The technician is using the command to add a default route to the server, which specifies the IP address of the default gateway that should be used for all traffic with an unknown destination.
