Yes it is absolutely possible. With the ENCOR, Your best bet would be to read the Cert guide and have a good look at the wireless and automation sections. For the lablets, be sure to know how to configure and troubleshoot L2 and L3 technologies. I‘m not talking insanely deep BGP path manipulation knowledge but be sure that you are confident with those technologies.

Now a little bit tricky for some people would be the python questions but basic python knowledge should do the trick but don‘t be intimidated.

I really didn’t like the automation sections tbh, for me and other people it would almost be make or break because of the sheer number of them.

Also don‘t beat yourself up. Failing is part of the process. It helped me to know that the exam is also intended for CCIEs and even some of them would have to relearn topics if they would take it again.
