Which of the following will not handle routing protocols properly?
A.
“Internet-router-firewall-net architecture”
B.
“Internet-firewall-router-net architecture”
C.
“Internet-firewall -net architecture”
D.
“Internet-firewall/router(edge device)-net architecture”
A
According to my book, ‘b’ ecsa v.8 page 89
I concur. Spelled out on page 89 of ECSAv8 Text “B”
“C” is also possible. Because firewalls can do routers jobs, if it is configured properly according to routing protocols. But here the BEST answer is “B”. Because such an architecture can not be possible (it is actually impossible design).
sure B
“B” is the authoritative answer from ECSAv8 courseware.
But anyone can explain why it is?
Because the firewall (if not correctly configured) might block certain (multicast/broadcast) packets required for routing protocols.
I know I may not get an answer, but can anyone tell me what this means? I can’t find anything on the Internet and I have the v8 PDFs and the v9 book, but I can’t find anything. It makes no sense. I have routers in front of and also behind firewall, and they all are able to use routing protocols (routing internally or externally, but not both of course). I have firewalls that also use routing protocols without any other routers. The question doesn’t say whether the protocols are internal or external, but either way, routing protocols can work on firewalls and routers. Of course and internal router won’t work with routing protocols implemented on the Internet side, but the question doesn’t say that.
