Review the exhibit. What would be the best routing command to allow host Certkiller A to communicate with host Certkiller B? (Assume a route from the 208 to Host Certkiller A’s subnet already exists.)

A.
set route 0.0.0.0/0inte2 gateway 192.167.1.254

B.
set route 192.168.20.0 interface e1 gateway 192.167.1.254

C.
configure route 192.168.20.0/24 gateway 192.167.1.254inte2

D.
set route 192.168.20.0/24 interface e2 gateway 192.168.1.254

Explanation:

When you want to connect to a remote network, you need to inform your firewall of itslocation.Youwould do this by adding network routes on your firewall. These routes tell the firewall where the remote network can be found. A
default route is also known as the route of last resort. So if a packet on a device needs to get to a location and no other routes on the device are able to identify the next gateway for it to go to, it will use the default gateway. To add a static route using the CLI, enter thecommand :set routeipaddress/netmaskinterfaceinterfacename
gatewaygatewayip, whereipaddressis the virtual router’s IP address,netmaskis thecirtualrouter’snetmask,
interfacenameis the next hop gateway, and gateway ip is the IP address of the next hop gateway.
In this scenario Certkiller A(10.1.10.5) wants to
communicate with Certkiller B (192.168.20.5). Certkiller A does not know the path to reach Certkiller B. Certkiller A knows the path to Router Certkiller 1 and Certkiller 1 knows the route to theNetscreen208. So Certkiller Acan
communicate with theNetscreen208.
However thenetscreen208 does not know the path to reach 192.168.20.x subnet, therefore we must tell thenetscreen 208 how to reach that subnet. We must tell thenetscreen 208, that it can reach subnet 192.168.20.x VIA router
Certkiller 2 that is connected to interface 2.
The command that we useis :set route 192.168.20.0/24 interface e2 gateway 192.168.1.254
