An administrator is configuring a new site-to-site IPsec VPN on a FortiGate. They have defined the Phase 1 interface, authentication method, and encryption algorithm. What is the next required step to complete the VPN configuration?

Configure a static route to the remote network

Enable NAT on the tunnel interface

Define the Phase 2 selectors and encryption settings

Create a firewall policy to allow traffic through the tunnel

A site-to-site IPsec VPN is experiencing frequent disconnections. The administrator checks the IKE debug logs and sees that Phase 2 SAs are being renegotiated every few minutes. The Phase 2 lifetime is set to 3600 seconds. What could cause this behavior?

The pre-shared key is being changed automatically

The tunnel is experiencing high traffic volume

The Phase 1 lifetime is set to 300 seconds

The remote peer has a shorter Phase 2 lifetime configured

A site-to-site IPsec VPN has been up for several hours. The administrator notices that the Phase 2 SA is renegotiated every 3600 seconds. What is the most likely reason for this behavior?

The tunnel is experiencing packet loss

The Phase 1 SA lifetime is configured to 3600 seconds

The Phase 2 SA lifetime is configured to 3600 seconds
