FORTINET-NSE7-SPECIALTY Practice Question: Nse7 SD Wan Security Profiles Routing And Ipsec
In an ADVPN 2.0 deployment, a hub unit uses BGP to advertise routes to spokes. When a spoke learns a prefix via BGP from the hub, what mechanism allows the spoke to automatically initiate an ADVPN shortcut tunnel directly to another spoke when traffic flows between them?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The FortiGate kernel detects traffic matching a dynamic BGP route over the IPsec interface and initiates an IKE shortcut negotiation with the target spoke
ADVPN shortcuts are triggered when traffic matches a shortcut trigger mechanism. In ADVPN 2.0, IPsec phase 1 shortcut settings ('set advpn shortcut') and dynamic routing protocols working together allow the kernel to generate shortcut requests when traffic hits the phase 1 interface.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
The FortiGate kernel detects traffic matching a dynamic BGP route over the IPsec interface and initiates an IKE shortcut negotiation with the target spoke
Why this is correct
Correct. When traffic hits the ADVPN tunnel interface for a destination learned via dynamic routing, the kernel triggers an IKE negotiation directly with the target spoke's public IP.
- ✗
OSPF sends a special multicast hello packet across the hub to establish mesh point-to-point links
Why it's wrong here
OSPF runs over the hub-and-spoke abstraction; shortcuts are established via IKE/IPsec data triggers, not OSPF multicast hello packets.
- ✗
FortiManager pushes a dynamic static route to both spokes simultaneously
Why it's wrong here
ADVPN shortcuts are dynamic and formed on-demand via data plane traffic triggers, not pushed statically by FortiManager.
- ✗
The Web Filtering profile intercepts the packet and redirects it via proxy to the destination spoke
Why it's wrong here
Security profiles do not trigger ADVPN shortcut establishment.
Quick reference
VPN Protocol Comparison
| Protocol | Port | Encryption | Authentication | Use Case |
|---|---|---|---|---|
| IKEv2 / IPsec | UDP 500 / 4500 | AES-256 | Certificates / PSK | Site-to-site & remote access |
| SSL / TLS VPN | TCP 443 | TLS 1.3 | Certificates / MFA | Clientless remote access |
| L2TP / IPsec | UDP 1701 | AES (IPsec) | PSK / Certificates | Legacy remote access |
| WireGuard | UDP 51820 | ChaCha20 | Public keys | Modern high-performance VPN |
| PPTP | TCP 1723 | MPPE (weak) | MS-CHAPv2 | Legacy — avoid in production |
PPTP is considered insecure. IKEv2/IPsec and SSL VPN are the current recommended options.
