Re: OER/PfR at lab exam?

I got excited when I saw this, but I see at the bottom that it was introduced in 12.4.24T. 12.4.10 doesn't support the pfr command-
Please explain as I'm seeing conflicting information as to your verbiage below.

How is the lab IOS version in need of PIRO if it's not supported? Maybe I labbed too late night night and just dense this morning- dunno. ;)
