Cisco Exam 300-440 Topic 3 Question 12 Discussion

Actual exam question for Cisco's 300-440 exam

Question #: 12
Topic #: 3

A company with multiple branch offices wants a connectivity model to meet its network architecture requirements. The company focuses on ensuring low latency and efficient routing for its critical business applications. Which connectivity model meets these requirements?

Ahub-and-spoke topology with SD-WAN technology, using dynamic routing and OSPF as the routing protocol

Bfully meshed topology with SD-WAN technology, using dynamic routing and BGP as the routing protocol

Cpoint-to-point topology using dedicated leased lines and static routing

Dstar topology with internet-based VPN connections and static routing

Show Suggested Answer

Suggested Answer: A, E

The correct answer is A and E because they are the IP prefixes that match the tunnel interfaces on the Cisco IOS XE router. The AWS routing options should include the local and remote IP prefixes that are used for the IPsec tunnel endpoints. The other options are either the public IP addresses of the routers or the LAN subnets that are not relevant for the IPsec tunnel configuration.Reference:=Designing and Implementing Cloud Connectivity (ENCC) v1.0,Configure IOS-XE Site-to-Site VPN Connection to Amazon Web Services,Site-to-Site VPN with Amazon Web Services

I'm leaning towards the fully meshed topology with SD-WAN and BGP. It provides more redundancy and can handle changes in the network better.

The hub-and-spoke topology with SD-WAN and dynamic routing using OSPF seems like the best option to ensure low latency and efficient routing for critical business applications.

That's a good point, but I still think a fully meshed topology would provide better redundancy and scalability for the network architecture.

I disagree, I believe option A is better as hub-and-spoke topology with SD-WAN technology can ensure low latency and dynamic routing for the company's branch offices.

I think option B is the best choice because a fully meshed topology provides the most efficient routing for critical business applications.
