Thanks Scott. I definitely believe in he KISS principle, but could I
possibly ask the proctor to clarify this situation or would that be
"against the rules"?

IMHO that would possibly require some extra work or thinking.
Confederations change the entire structure where if you had multiple
eBGP
neighbors, it would affect them as well. Local-as affects a per-peer
configuration only which makes it a little simpler.
In this example, both would accomplish the same thing though, just be
aware
of the potential difficulties moving forward!

I see that the solution uses LOCAL-AS NO-PREPEND, but I set it up using
CONFEDERATIONS and got the same result.

Would this be considered acceptable since there is no mention of not
being
able to use confederations or explicit use of local-as?
