Hi @Mumshad Mannambeth / All. In the https://kodekloud.com/topic/practice-test-explore-environment-2 Question 3., its asked ‘What is the network interface configured for cluster connectivity on the master node?’ . Using ifconfig -a we can see all the interfaces but cannot really tell which one is connected to cluster for the masterNode and I dont see a file called interfaces in the directory /etc/network/ .

@Brian Gumisiriza took your advice and I did ip a and also grepped for UP . I see eth0 and eth1 , how will i understand whichone among them is the right one.

Brian Gumisiriza:
I noticed the master IP addresses keep changing according to the sessions.
Two ways to get the answer.
Run

ip a

And look for the interface in the same line where the master IP is
Or

 ip a | grep  &lt;master-ip address&gt;

So the the Interface is eth0 as show below

root@controlplane:~# ip a | grep 10.42.74.12
    inet 10.42.74.12/24 brd 10.42.74.255 scope global eth0
