Quiz: addresses and routes

One correct answer

On the practice machine ip -brief -4 address shows only lo, while sudo ip -n lab-client -brief -4 address also shows lab0. Why?

• A lab0 is down, so the first command does not print it.
• B Without sudo, ip hides some interfaces.
• C -n creates the lab0 interface.
• D lab0 is in a separate network namespace, lab-client.
