Answer: C

Explanation:

Before deploying MXs as one-arm VPN concentrators, place them into Passthrough or VPN Concentrator mode on the Addressing and VLANs page. In one-armed VPN concentrator mode, the units in the pair are connected to the network "only" via their respective ‘Internet’ ports. Make sure they are NOT connected directly via their LAN ports. Each MX must be within the same IP subnet and able to communicate with each other, as well as with the Meraki dashboard. Only VPN traffic is routed to the MX, and both ingress and egress packets are sent through the same interface.
