Question 730
At Meadowbrook Finance, the enterprise firewall operations team administers FortiGate-based protection for payment gateways and regional private network connections under requirements for tight access controls and tested failover. Following the approved change, the team must validate: An SD-WAN application steering rule matches every source address because a broad firewall source group replaced the intended branch subnet. Which observed outcome BEST demonstrates that the intended correction works?
Explanation
Correct Answer
The selected branch flow is steered to its intended member and unrelated clients follow their ordinary SD-WAN routing policy. This outcome validates the intended correction for: An SD-WAN application steering rule matches every source address because a broad firewall source group replaced the intended branch subnet. The associated approved corrective action is: Narrow the SD-WAN service rule's source and destination selectors to the approved application traffic. The Meadowbrook Finance reviewer can therefore distinguish observable protection from an untested configuration claim.
Incorrect Answers
The remote test endpoint observes the intended FortiGate source IP and the local-out probe follows the expected gateway. This would verify a separate corrective action: Configure the supported local-out source interface and address for the diagnostic or management traffic independently of transit routing. That separate change addresses: A packet capture shows traffic on the expected ingress port but the firewall replies using the wrong source address for its own local-out probe. It does not validate the current Meadowbrook Finance issue: An SD-WAN application steering rule matches every source address because a broad firewall source group replaced the intended branch subnet. The relevant acceptance evidence is: The selected branch flow is steered to its intended member and unrelated clients follow their ordinary SD-WAN routing policy.
A controlled request to the obsolete prefix is discarded locally while more specific valid routes continue to forward traffic. This would verify a separate corrective action: Use an appropriately scoped blackhole route for the obsolete destination prefix with a deliberate distance and precedence. That separate change addresses: A routing loop sends packets toward a decommissioned network because no explicit safe discard route exists for an obsolete summary prefix. It does not validate the current Meadowbrook Finance issue: An SD-WAN application steering rule matches every source address because a broad firewall source group replaced the intended branch subnet. The relevant acceptance evidence is: The selected branch flow is steered to its intended member and unrelated clients follow their ordinary SD-WAN routing policy.
The controlled flow has both an intended route and an explicit allow-policy match without an unnecessary duplicate route. This would verify a separate corrective action: Inspect policy-match logs and the route separately, then modify only the control that actually denies the approved session. That separate change addresses: An operations team adds a static route to allow a blocked application even though the FortiGate's existing routing table already reaches the destination. It does not validate the current Meadowbrook Finance issue: An SD-WAN application steering rule matches every source address because a broad firewall source group replaced the intended branch subnet. The relevant acceptance evidence is: The selected branch flow is steered to its intended member and unrelated clients follow their ordinary SD-WAN routing policy.
