If they did put Best Chance or Be Sure That R3... You need to also think
that what happens if you had to added R2 later on. If that where the
case, then R2 or R3 would have equal priorities and thus both be
candidates.

Did the question ask something like "ensure that R3 has the best chance
of being selected"? Then I would imagine setting the priority to 255 is
correct.

Hi Buddies,

I tried the assessor lab yesterday and got a very strange question. For
a FR NBMA network in which R3 is hub and R1, R4 as spoke. I put R1, R4
priority to 0 and make R3 unchanged. The final result is that I got 0
for this question and they indicate that because I did not put priority
for R3 as 255. Anyone here know the reason that I must set it to 255
instead of leaving it as default 1? Thanks.
