R15 is building a Site-to-Site IPsec certificate-based VPN tunnel with the peer at 20.1.7.16. The CA is running at port 80 on address 172.16.100.18. R15 has a BGP peer at 20.6.1.18 doing an authenticated session to establish reachability with the VPN remote site.

The VPN tunnel secures traffic between 192.168.15.0/24 and 192.168.16.0/24 networks.

A . Incorrect ACL defined for the traffic encryption
B . Incorrect static route
C . Incorrect crypto map configuration
D . Incorrect ISAKMP policy configuration
E . The crypto map is not applied on the correct interface
F . Incorrect truspoint configuration
G . Incorrect BGP peer Configuration
H . Incorrect transform set configuration
