Sapan Kumar:
As i mentioned in my other post, remember to switch to correct nodes as per the question - i messed up with etcd restore 
. Cluster upgrade and etcd restore questions were on the same cluster and my pods were not coming up post restore, so i think both of the questions were marked failed although my upgrade was successful. There was some confusion with the documentation that was sorted last minute but i request everyone to practice it several times until it is clear.
Lucas Herculano:
Thank you for the detailed answer.
Fayaz Rehman:
Do you have to login to master node from student@node-01 for etcd backup with sudo -i
