OK, I really headed your advice on this one and continue to ensure that I
can recall this accurately and quickly.

I'm doing a wrap-up of my BGP studies for the written and I still don't feel
as though I understand what's being said here. Can you elaborate or point
me in a direction?

I don't mind the written at all. I'm looking forward to seeing how well I
test on this stuff. I haven't sat a Cisco exam since recertifying CCNP/CCDP
about three years ago. My recollection is that those exams (you had to
retake both BSCI and BCMSN back then, I guess only one does the trick now)
were more difficult than the ones I originally had taken to get the
certifications in the first place. So this should be interesting...
