The answer to this question really hinges on if the Licenses are perpetual (Single-Use = CAPEX) or if they are subscriptions (Recurring = OPEX). I'm going to assume we're using Cisco licensing in this example so they will be subscription-based licenses and therefore considered OPEX. Since none of the requirements for the WAN are only met with SDWAN, DMVPN is still an option, especially since Cisco SDWAN typically uses subscription licensing based on circuit bandwidth. In that case, the answer is A. DMVPN over L3VPN

Selected Answer: D

least opex - eiminates first 2 options. in-house ("done within an organization or business by its employees rather than by other people") eliminates 3rd option. So answer is clearly D.

In the question it states "in-house", which means they're not going to go with anything managed, therefore B is not the solution. There's growth expected and based on the question, they are looking for SD-WAN features.
