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?
A) hub-and-spoke topology with SD-WAN technology, using dynamic routing and OSPF as the routing protocol
B) fully meshed topology with SD-WAN technology, using dynamic routing and BGP as the routing protocol
C) point-to-point topology using dedicated leased lines and static routing
D) star topology with internet-based VPN connections and static routing

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?

Show Suggested Answer Hide 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
