B 5
Selected Answer: B
Correct answer is B since AS100 is the neighboring AS of R6 so it will be always the 1st in the AS path, and we don't want to see any other AS behind AS100, so it has to be ^100$

^ means AS number start with
$ means AS number end with
so, we only want routes from AS100 then ^100$

B 1
Selected Answer: B
In R6 if we notice the bgp table, the sentence *> Net: 6.6.6.6/32 ............ Path: 100 500,
I think it should be: *> Net: 6.6.6.6/32 ............ Path: 500 100
Shouldn't it?
