FORTINET-NSE7-SPECIALTY Practice Question: Nse7 SD Wan Security Profiles Routing And Ipsec
An administrator is troubleshooting an SD-WAN deployment where traffic matching an SD-WAN rule with a destination service object (e.g., HTTPS) is not being steered according to the SLA priority. Instead, it is always taking the default static route member. Upon checking the firewall policies, what is the most common reason why an SD-WAN rule fails to process application or service-based traffic matching?
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 SD-WAN rules are evaluated sequentially from top to bottom; an earlier broad SD-WAN rule with matching source/destination IP addresses is intercepting the traffic before the service-specific rule is reached
For SD-WAN rules based on applications or destination services to take effect, the matching firewall policy must have application control or appropriate inspection enabled, or the SD-WAN rule position/criteria order must match correctly. Furthermore, explicit proxy or policy routing interactions can interfere if implicit firewall rules intercept the traffic first.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
IPsec VPN phase 2 selectors must be set to 0.0.0.0/0 for service-based rules to evaluate
Why it's wrong here
Phase 2 selectors do not dictate SD-WAN rule evaluation order.
- ✓
The SD-WAN rules are evaluated sequentially from top to bottom; an earlier broad SD-WAN rule with matching source/destination IP addresses is intercepting the traffic before the service-specific rule is reached
Why this is correct
Correct. SD-WAN rules are evaluated top-down. If a broader rule matches the traffic first, the more specific service-based rule below it is never evaluated.
- ✗
The firewall policy containing the traffic has SSL inspection disabled, preventing service-based identification
Why it's wrong here
While SSL inspection helps identify specific HTTPS websites, service objects like TCP/443 are based on port numbers and do not strictly require SSL inspection to match service rules.
- ✗
The FortiGate kernel requires hardware acceleration (NP7) to be disabled for service-based SD-WAN rules to function
Why it's wrong here
Hardware acceleration does not prevent SD-WAN rule matching.
