Roberto Sebastiano:
Hello, just got the CKA exam with some strange issues on two nodes … not sure if it was part of the exam or a problem within the system ? /proc/cpuinfo was returning “Transport endpoint is not connected”. /proc/cpuinfo was mounted via lxcfs (!?). Was this part of the curriculum ? I have to say that I don’t know if I passed it or not (a lot of time debugging this)
Nathanael Fuog:
i can not tell for sure but i think i had something like you in the exam yesterday “Transport endpoint is not connected”
Nathanael Fuog:
maybe they have problems with the exam setup
Nathanael Fuog:
i didn’t 
i skipped and moved on
Roberto Sebastiano:
I solved it instead 
umount /proc/cpuinfo (and other files under /proc)
Syed Hassan:
ok Great @Nathanael Fuog congratulations for passing the exam. and @Roberto Sebastiano great effort by you. I will give exam before October
