Why?

Refer to the exhibit, which contains a screenshot of some phase 1 settings.

The VPN is not up. To diagnose the issue, the administrator enters the following CLI commands to an SSH session on FortiGate: diagnose vpn ike log-filter dst-addr4 10.0.10.1 diagnose debug application ike -1

However, the IKE real-time debug does not show any output.

Why?
A . The administrator must also run the command diagnose debug enable.
B . The administrator must enable the following real-time debug: diagnose debug application ipsec -1.
C . The log-filter setting is incorrect. The VPN traffic does not match this filter.
D . The debug shows only error messages. If there is no output, then the phase 1 and phase 2 configurations match.
