Re: OER/PfR at lab exam?

I agree to that, Marc. I have run a few labs with it. I have read Doc CD a
few times for comprehension. I will continue to spin up just on the basics.

Regardless if I see it on the exam, I have intrest to use this in my
business environment. Mastery will be good before making any hasty
decisions.

I am looking forward to session and will keep my eyes out for an invite.

Regards,

Marc
