Refer to the Exhibit.
You have created an IPsec VPN on an SRX Series device. You believe the tunnel is configured

correctly, but traffic from a host with the IP address of 10.12.1.10 cannot reach a remote device
over the tunnel with an IP address of 10.128.64.132. The ge-0/0/1.0 interface is in the trust zone
and the st0.0 interface is in the vpn zone. The output of four show commands is shown in the
exhibit.
What is the configuration problem with the tunnel?

A.
Only one IKE tunnel exists so there is no path for return IKE traffic. You need to allow IKE
inbound on interface ge-0/0/0.0.

B.
Because there are no IPsec security associations, the problem is in the IPsec proposal settings.

C.
The static route created to reach the remote host is incorrect.

D.
The VPN settings are correct, the traffic is being blocked by a security policy.
