Refer to the exhibit.
A network administrator is troubleshooting an IPsec tunnel between two FortiGate devices. The administrator has determined that phase 1 failed to come up. The administrator has also re-entered the pre-shared key on both FortiGate devices to make sure they match.
Based on the phase 1 configuration and the diagram shown in the exhibit, which two configuration changes can the administrator make to bring phase 1 up? (Choose two.)

A. On both FortiGate devices, set Dead Peer Detection to On Demand. B. On HQ-FortiGate, set IKE mode to Main (ID protection). C. On HO-FortiGate, disable Diffie-Helman group 2. D. On Remote-FortiGate, set port2 as Interface.
