The exhibit shows output from two show commands.
What are two conclusions about the VPN tunnel from the output? (Choose two.)

A.
VPN monitoring is enabled.

B.
There is a device performing NAT between the two VPN endpoints.

C.
3DES is the encryption protocol.

D.
Traffic with the DF-bit set that exceeds the MTU will be dropped.
