Fortinet NSE8_812 Exam With Confidence Using Practice Dumps

A is correct because using network-overlay id allows you to configure multiple ADVPN tunnels on a single interface with a single IP address on the DC FortiGate. This is explained in the FortiGate Administration Guide under ADVPN > Configuring ADVPN > Configuring ADVPN on the hub. References:

The output in Exhibit A shows that the VPN tunnel is not established because the peer IP address is incorrect. The output in Exhibit B shows that the peer IP address is 192.168.1.100, but the baseline VPN configuration in Exhibit C shows that the peer IP address should be 192.168.1.101.

To restore VPN connectivity, you need to change the peer IP address in the VPN tunnel configuration to 192.168.1.101. The correct configuration is shown below:

config vpn ipsec phase1-interface

edit "wan"

set peer-ip 192.168.1.101

set peer-id 192.168.1.101

set dhgrp 1

set auth-mode psk

set psk SECRET_PSK

next

end

Option A is incorrect because it does not change the peer IP address. Option B is incorrect because it changes the peer IP address to 192.168.1.100, which is the incorrect IP address. Option D is incorrect because it does not include the necessary configuration for the VPN tunnel.
