NSE7_SDW Security Profiles Routing And IPsec Practice Question
An administrator troubleshoots an ADVPN 2.0 deployment where dynamic shortcut tunnels fail to establish between branch spokes. Which THREE diagnostic steps or log checks should the administrator perform on the FortiGate hub or spoke to isolate the issue? (Choose three)
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
✓
Check 'diagnose vpn tunnel list' to verify if dynamic shortcut child security associations are being created
Troubleshooting ADVPN shortcut failures requires checking IPsec status, IKE exchanges, routing table entries, and network device creation. Valid diagnostic steps include checking IKE daemon output, verifying IPsec tunnel status, and inspecting routing table entries for shortcut triggers.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Check 'diagnose vpn tunnel list' to verify if dynamic shortcut child security associations are being created
Why this is correct
Correct. This command shows active child SAs, confirming whether the shortcut tunnel has successfully built.
- ✗
Check the firewall policy statistics to ensure SD-WAN rules have zero hit counts globally
Why it's wrong here
SD-WAN hit counts do not diagnose IKE/IPsec shortcut negotiation failures.
- ✓
Run diagnose vpn ike log-filter ... and enable IKE real-time debugging to inspect negotiation messages between spokes
Why this is correct
Correct. IKE real-time debugging helps identify phase 1/2 negotiation failures during shortcut establishment between spokes.
- ✗
Execute 'execute format disk' to reset the internal flash storage and clear corrupted ADVPN certificates
Why it's wrong here
Formatting disk erases all system data and is never a troubleshooting step for ADVPN.
- ✓
Verify that 'get router info routing-table database' contains the dynamic shortcut routes injected when traffic hits the phase 1 interface
Why this is correct
Correct. Inspecting the routing table verifies whether shortcut routes are being dynamically added when data traffic triggers the shortcut.
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.
