- tunnel-group 188.8.131.52 type ipsec-l2l
- tunnel-group 184.108.40.206 type s2s
- tunnel-group SiteB type ipsec l2l
- tunnel-group SiteB type s2s
The correct answer is 1.
LAN to LAN VPNs will use a connection profile with the IP address of the peer being connected to. Hence options C and D are not valid because they use a name instead of an ip address as the identifier for the connection profile. Option B is also incorrect because although it uses an ip address to identify the connection profile, the syntax of s2s is not valid.
