Question 250
At Harborline Logistics, the WAN and firewall administration team administers FortiGate-based protection for a multi-depot shipment tracking network under requirements for verified route health and appropriate egress restrictions. Following the approved change, the team must validate: An IPv6 subnet has a working route through FortiGate but its security rules cover only IPv4 address objects and IPv4 sessions. Which observed outcome BEST demonstrates that the intended correction works?
Explanation
Correct Answer
An authorized IPv6 test flow follows an explicitly logged IPv6 policy and an unapproved IPv6 connection is denied. This outcome validates the intended correction for: An IPv6 subnet has a working route through FortiGate but its security rules cover only IPv4 address objects and IPv4 sessions. The associated approved corrective action is: Create the required IPv6-specific firewall policies and address objects under the supported FortiOS policy model. The Harborline Logistics reviewer can therefore distinguish observable protection from an untested configuration claim.
Incorrect Answers
A controlled loss of the primary collector permits the approved identity policy to continue through the expected redundant service. This would verify a separate corrective action: Design supported collector redundancy or a documented alternative authentication path while keeping group matching consistent. That separate change addresses: A single FSSO collector becomes unavailable and all identity-based firewall policies stop authorizing domain users. It does not validate the current Harborline Logistics issue: An IPv6 subnet has a working route through FortiGate but its security rules cover only IPv4 address objects and IPv4 sessions. The relevant acceptance evidence is: An authorized IPv6 test flow follows an explicitly logged IPv6 policy and an unapproved IPv6 connection is denied.
An approved user's identity entry includes the required group and reaches only the destination permitted to that group. This would verify a separate corrective action: Configure the supported collector group retrieval and the firewall's FSSO user group mapping for those authorized directory groups. That separate change addresses: Users can log in to Windows but FortiGate FSSO policies still deny them because the collector does not retrieve their allowed Active Directory groups. It does not validate the current Harborline Logistics issue: An IPv6 subnet has a working route through FortiGate but its security rules cover only IPv4 address objects and IPv4 sessions. The relevant acceptance evidence is: An authorized IPv6 test flow follows an explicitly logged IPv6 policy and an unapproved IPv6 connection is denied.
Controlled requests from each department show the correct distinct approved public source address in external records. This would verify a separate corrective action: Assign the intended source NAT IP pools to the relevant policies or supported central NAT mappings by department. That separate change addresses: Several departments must egress through different public addresses for attribution but all FortiGate policies use the WAN interface address. It does not validate the current Harborline Logistics issue: An IPv6 subnet has a working route through FortiGate but its security rules cover only IPv4 address objects and IPv4 sessions. The relevant acceptance evidence is: An authorized IPv6 test flow follows an explicitly logged IPv6 policy and an unapproved IPv6 connection is denied.
