disclaimer: I've never posted here, and although I've read the rules, I dunno if you'd consider this brain dump stuff since I got my image from one of those sites.
I'm currently taking the Cisco CCNA netacad courses in school and I just finishing my scaling networks final. There's one question I received that is making me crazy because it appears ( to me, but I'm new, and there may be some major factor I'm missing, but I don't think so) as though the correct answers aren't given as options.
https://imgur.com/by90q19 is a snip of the question with the correct answers I got from one of those final test bank sites.
It seems to me, where all of the routers in the question have the default priority (1) and every explicitly set priority is also 1, that we'd go to highest router ID first to elect the DR and BDR. In area 1 only R1 has a router ID defined, so it'd be that area's DR, and since R2 is the only router with a loopback configured, that'd be our BDR for that area. In area 2 R4 has a router ID and no one else does, thus DR, and R5 has a loopback configured, and R3 doesn't, it's a lower address then R4's but it can't be both DR and BDR, so R5 should take it.
So am I missing something, or is this question just broken? It doesn't really matter besides saving my piece of mind, and I'd rather know then not if I failed to learn something. Any help would be appreciated. Also, sorry if I broke any rules.
