Lab SSH and SCP

HI Team,

I am trying to for key pairing using the ssh-keygen -t rsa in bob@devapp01. I could see terminal accepted all commands but test is still showing as failed.

Please correct me.

Getting error for next question, I think I am missing some major syntax.
I was asking to add id so i used ssh-copy-id bob@devapp01 but task is failed with reason Password-less ssh is not working from Bobs laptop to devapp01
