FORTINET-NSE7-SPECIALTY Practice Question: Nse7 SD Wan Security Profiles Routing And Ipsec
An administrator configures an SD-WAN rule using the 'Volume' strategy across two IPsec tunnels with different bandwidth capacities (Tunnel A: 100 Mbps, Tunnel B: 50 Mbps). How does FortiOS distribute traffic across these members when using the Volume strategy?
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
✓
Traffic is distributed proportionally based on the configured weight or bandwidth ratio of each member interface
The Volume strategy in SD-WAN distributes traffic proportional to the configured volume/weight (bandwidth capacity) of each member 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.
- ✗
Traffic is balanced equally (50/50) regardless of interface capacity
Why it's wrong here
Equal load balancing is performed by the spillover or source-ip based strategies without weight consideration.
- ✗
Traffic is sent exclusively over Tunnel A until it reaches 100% packet loss, then fails over to Tunnel B
Why it's wrong here
That describes a priority/failover strategy, not a volume-based load-sharing strategy.
- ✓
Traffic is distributed proportionally based on the configured weight or bandwidth ratio of each member interface
Why this is correct
Correct. Volume-based strategy divides traffic proportionally according to the weights assigned to the SD-WAN members, matching their respective link capacities.
- ✗
Traffic is steered strictly based on real-time latency measured by health checks
Why it's wrong here
Latency-based steering uses SLA metrics, not volume ratios.
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.
