Refer to the Exhibit.

An IP tunnel connects two routers over the Internet as shown in the exhibit.
Which two statements are correct? (Choose two.)

A.
A tunnel interface can serve as a next hop for static routes or participate in the network’s IGP.

B.
Routing protocols will always prefer a tunnel over a physical link because the tunnel is a onehop link with the lowest cost path.

C.
You can ensure the IP tunnel serves as the backup path through administrative settings such
as cost and route preference.

D.
IP tunnels are subject to the same simple firewall rules as the direct link between the two
routers, because the original IP header contents are open for the transit devices to see.
