Suggested Answer: D

A fully meshed topology with SD-WAN technology using dynamic routing and prioritized traffic for QoS meets the network architecture requirements of the company. A fully meshed topology provides high availability by eliminating single points of failure and allowing multiple paths between branch offices. SD-WAN technology enables multihoming by supporting multiple transport options, such as MPLS, internet, LTE, etc. SD-WAN also provides QoS by applying policies to prioritize traffic based on application, user, or network conditions. Dynamic routing allows the SD-WAN solution to adapt to changing network conditions and optimize the path selection for each traffic type. A fully meshed topology with SD-WAN technology can also support specific routing needs, such as segment routing, policy-based routing, or application-aware routing.Reference:

Key pairs? Really? That's more for authentication, not network security. I think the engineer should go with security groups on this one.

I also think security groups is the right choice. It's a common practice to use them for network security in AWS.

I agree with Nathan. Security groups can help secure the nodes on the network side.

I'm not sure, but I think security groups make sense because they control inbound and outbound traffic.

Hmm, security groups seem like the obvious choice here. They allow you to control inbound and outbound traffic to your nodes, which is exactly what the engineer needs to secure the network.
