QuestionQ4

Advanced IPsec

Refer to the exhibit.

Question Image

You used the SD-WAN overlay orchestrator to prepare an IPsec tunnel configuration for a hub-and-spoke SD-WAN topology. The exhibit displays the FortiManager installation preview for one FortiGate device.

Based on the exhibit, which statement accurately describes the configuration applied to the FortiGate device?

  • A It is a hub device. It will automatically discover the spoke devices and add them to the SD-WAN topology.
  • B It is a spoke device that establishes dynamic IPsec tunnels to the hub. The local subnet range is 10.10.128.0/23.
  • C It is a hub device. It can send ADVPN shortcut offers.
  • D It is a spoke device that establishes dynamic IPsec tunnels to the hub. It can send auto-discovery VPN (ADVPN) shortcut requests.
Explanation

A dynamic Phase 1 IPsec interface configured with peertype any is the hub-side configuration that accepts dialup connections from spokes. Enabling auto-discovery-sender on that hub enables it to send ADVPN shortcut offers. Fortinet’s ADVPN hub examples use this same combination of settings.
