Dan Makovec:
@Mumshad Mannambeth “Explore Kubernetes Environment” practice test. The question asks about the state of docker0 and presumably the correct answer is set as “DOWN”, although for both controlplane and node01 it’s set to “UP”…
Dan Makovec:
Also an earlier question asked about the IP of node01. The accepted answer was .2 but the actual IP was .3 (which wasn’t in the list)
Dan Makovec:
And I believe a question about the MAC addresses was wrong too (different address presented to the available options)
Raamkanna Saranathan:
the course mentions that you should use ip link or ip addr commands, not ifconfig.
Dan Makovec:
Hmm, force of habit. Thanks @Raamkanna Saranathan! Now I’m going to have to read up on the output diffs 
Dan Makovec:
incidentally the output from ip link is a little confusing - in the one line I see “UP” and “DOWN”:
docker0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc noqueue state DOWN
Subrata Biswas:
ip link shows both the admin status of interface and link or media status connected to it so the interface is admin up but link is down which means port is switched on but there is not cable connected to it or other end of the cable does not active device
Dan Makovec:
so admin status is between the angle brackets, and link status = “state” outside the brackets? Gotcha thanks
Subrata Biswas:
yep
