Answer options

• A. The address 192.168.1.20 is associated with the interface eth0.
• B. A network route to 192.168.1.0 with the netmask 255.255.255.0 pointing directly to eth0 is created.
• C. 192.168.1.1 is probed for router functionality and, in case of success, it is added to the list of default routers.
• D. The addresses from 192.168.1.20 to 192.168.1.24 are activated on the interface eth0.
• E. If eth0 was configured with a previous IP address, it is retained in addition to adding the new address.

Correct answer: A, B

Explanation

Option A is correct because the command directly assigns the IP address 192.168.1.20 to eth0. Option B is also correct as it creates a route for the specified network with the given netmask. The other options do not accurately reflect the function of the ifconfig command in this context.
