NSE4 · Question #438

Which portion of the configuration does an administrator specify the type of IPsec configuration (either policy-based or route-based)?

The correct answer is D. Under the firewall policy settings.. The type of IPsec configuration (policy-based or route-based) is determined by how the VPN is integrated into the firewall policy, which directs traffic to the VPN tunnel.

Why each option

The type of IPsec configuration (policy-based or route-based) is determined by how the VPN is integrated into the firewall policy, which directs traffic to the VPN tunnel.

AUnder the IPsec VPN global settings.

Global settings typically apply to general VPN parameters or common settings, not the fundamental type of traffic routing for a specific VPN.

BUnder the phase 2 settings.

Phase 2 settings define the IPsec Security Association (SA) parameters, such as encryption and authentication algorithms, but do not determine the VPN type.

CUnder the phase 1 settings.

Phase 1 settings establish the IKE Security Association (SA) for secure key exchange parameters like encryption, authentication, and lifetime, which is independent of the VPN type.

DUnder the firewall policy settings.Correct

On devices like FortiGate, the choice between policy-based and route-based IPsec is implicitly made when configuring the firewall policy that utilizes the VPN, either by specifying traffic selectors (policy-based) or by selecting an IPsec tunnel interface (route-based).
