Refer to the exhibit. Which result of running the command is true?
A. authenticates the IKEv2 peers in the 172.16.0.0/16 range by using the cisco123 key
B. secures all the certificates in the IKE exchange by using the cisco123 key
C. authenticates the IKEv1 peers in the 172.16.0.0/16 range by using the cisco123 key
D. authenticates the IP address of the 172.16.0.0/32 peer by using the cisco123 key
C
Should be C. Although you can specify the subnet mask in the same command, without having that specified it accepts anything within the classful boundaries.
I would say D as this is the peer for IKEV1
