The WAN IP address is 172.18.46.2

Answer is A, please update

Selected Answer: A
A is correct.
The D in the list means "dynamic", which is a sign that it is another spoke. The hub is statically configured and therefore gets an "S".
The first IP is the public IP in the list. The second IP is the IP of the tunnel interface.
You can see this by looking at the heading. "Peer Tunnel Add" comes after the "Peer NBMA Addr". The tunnel address is the (typically private) address you assign to the tunnel interface.

This reason being is the NMBA address is the private and the Peer is the public and the first one which is 172.18.16.2 is not is because that is the Hub configured with a static mapping as it has "S" on the end. However when the address 172.18.46.2 is learned by the spoke it places a "D" at the end

Answer is A
IP-Address 192.168.1.4 is the tunnel interface address
IP-Address 172.18.46.2 is the WAN interface address
D stands for dynamic tunnel which is created between spokes

Correct answer is A. It's in the NBMA field in the output of the sh cmd. The S on the far right means that neighbor is the HUB, while dynamic or D is other spokes because they are dynamically discovered.

Selected Answer: A
Answer is A.
The WAN IP is NBNA address, which is the device physical interface.
S will be the HUB.
D will be the spoke who learns the other spoke address dynamically.
When you do the command "show dmvpn". The first IP address is the NBMA address and the IP address after is the Tunnel IP address.

The option A, first the NMBA address are the wan ip address and second the NHRP registration is marked as dynamic (D). registrations made to the hub are marked as static (S)

hard to say what cisco means by "WAN IP". It looks more like the "inner" IP than the "outer/NBMA" IP. If we stick to the fact that "WAN" is customer's wide area network, then they ask about inner IP - which is D. I don't like question where they juggle with words...

Selected Answer: A
Cannot be the S = Static because that would be the Hub & Peer NBMA Addr is the Outside/WAn address
1
Other way around. Hubs are dynamic, so S (Static) means it's a spoke.
1
Ignore that. Spoke-to-hub connection is S when viewed from the spoke side.

WAN address is physical address of WAN interface, not the logical address of the tunnel interface. Not sure where you see the word "inner" used. What are they juggling? Physical address is the 172.18.X.X address on the left, which is A.

Selected Answer: A
A is correct, the D flag is dynamic so that is the spoke, while the hub has the S (static) flag

Selected Answer: D
D is correct. NBMA is the public IP address set on peer WAN Interface

NBMA is the underlay address mate not public IP which is the overlay address.
