Refer to the exhibit. An architect is developing a solution to consolidate networks while retaining device redundancy. The routing protocol for the WAN routers must be open standard, ensure high availability, and provide the fastest convergence time. Which solution must the design include?
The routing protocol for the WAN routers must be an open standard, ensure high availability, and provide the fastest convergence time. Open Shortest Path First (OSPF) is an open standard routing protocol that is widely supported across different vendors. While Enhanced Interior Gateway Routing Protocol (EIGRP) has been made an open standard, it is still predominantly associated with Cisco devices and may not provide the vendor-neutrality desired in many networks. Additionally, both OSPFv2 and OSPFv3 can run concurrently, handling IPv4 and IPv6 respectively, ensuring high availability and fast convergence. Therefore, the best solution is to have both routers running OSPFv2.
EIGRP is an open standard protocol for years now, Also If we go with Answer B -> How could we guarantee "High availability" of one router is running OSPFv2 (for IPv4) and one running OSPFv3 (for IPv6) ... If one router failes (for example the OSPFv2 one) -> Then the IPv4 traffic would have to go through the OSPFv3 router, but since that is not configured up for IPv4 it would drop the packets. EIGRP has a function called "EIGRP Ipv6" (But that can still be called "EIGRP") So I guess it should be Answer A But shame on Cisco for asking bad questions like these... Its not about knowing the answer, its about seeing into the guys head who wrote the question and try to guess his thoughts.
EIGRP is already open standard for a few years. A is correct
On which devices in production (if ever), have you configured EIGRP ? Just wondering...
Idk man this question sucks. Coming back to it a month later I still don't know the answer. Open standard: could mean OSPF or EIGRP High availability: we are only using a single router per IP space. hA doesn't apply here Fastest convergence: what convergence are we covering? There is only one router. If the ipv4 router goes down, goodnight. Same with ipv6. There is nothing to converge. Furthermore, "both routers running EIGRP" is an unfair answer. "both routers running OSPF" should then also be an answer. Yes opsfv3 is synonymous with ipv6 and EIGRP doesn't contain that nomenclature But this is all so ridiculous. The word games in this question and answers takes away from the fundamentals of a network engineer. We shouldn't be tested on how well we can understand Cisco English.
The Answer is B. EIGRP is an open standard and it it provides faster convergence times than OSPF, HOWEVER, the term EIGRP is meant to be for IPv4 and in this case we need EIGRP for IPv6, unfortunately i don't see an option in the answers that say EIGRP for IPv6, the book explains this a lot, the safer answer is OSPFv2 for IPv4 and OSPFv3 which handles IPv6
What crack have you smoked lately? EIGRP is Cisco proprietary.

B/C. if only one router run OSPF v2 (doesn't support IPv6) and one router run OSPFv3 (support IPv6), or one run ISIS, it will not able to meet high availability and fastest convergence D: OSPFv2 does not support IPv6 so my answer is A
Everywhere I've searched, EIGRP is not considered an open standard....
it has became open since 2013-14 https://community.cisco.com/t5/routing/eigrp-was-cisco-proprietary-is-it-an-open-standard-protocol-now/td-p/2528505
Even, so features are extremely limited on non-cisco OS
eigrp is not open standard. so the realistic solution should be using both ospfv2 and ospfv3 on all routers.
option E , both routers running OSPFV3.
No 3rd party vendor is going to support EIGRP on their network. what a dumb question. This is a marketing question and not a real-world question. Because of that, I am regretfully going with A, because Cisco is trying to market EIGRP now as Open. but we all know the real world answer is B.
B is correct for me. It would of Specified EIGRP for IPv6 and it did not in the answers, i cannot accept A as the correct answer.
Eigrp it is not an open standard protocol, OSPF it is. The answer is B for me too
Think this B, A doesn't seem right
