i think A&E is correct. because The IPsec Dead Peer Detection Periodic Message Option feature is used to configure the router to query the liveliness of its Internet Key Exchange (IKE) peer at regular intervals. The benefit of this approach over the default approach (on-demand dead peer detection) is earlier detection of dead peers.

GRE tunnels require that the WAN Edge routers have public IP addresses. IPsec tunnels can be used with WAN Edge routers that are behind NAT.
