The exhibit contains IKE debugging messages generated during the ADVPN shortcut discovery process. The important entries include SHORTCUT_QUERY , the incoming shortcut query, the route lookup, and NAT hole-punching information.

Option D is supported by the behavior shown in Fortinet ' s published ADVPN examples. In the ADVPN shortcut establishment workflow, an initiating spoke can send a shortcut query toward its hub. The hub forwards the discovery information to the destination spoke, which receives that query on its hub-facing tunnel and prepares the subsequent shortcut negotiation.

Fortinet ' s official ADVPN examples show a destination spoke receiving SHORTCUT_QUERY on its tohub interface, followed by route lookup and shortcut-related operations. The exhibit ' s HUB1-VPN1 naming is consistent with a spoke-side tunnel toward Hub 1, although interface names alone do not establish the device ' s role.

Option A is not supported because the displayed log does not demonstrate direct receipt from another spoke. Option B would require evidence that the device is the forwarding hub. Option C incorrectly treats discovery messages as proof of an established shortcut.

The NAT hole-punching entry indicates shortcut negotiation activity, not completion. The strongest interpretation of the provided debug sequence is a destination spoke receiving a forwarded shortcut query from its hub.

The hub must send additional paths to spokes (set additional-path send). The hub must treat each spoke as a route-reflector client so spoke routes are reflected to other spokes. The hub must specify how many additional paths to advertise (set adv-additional-path < n > ). An operational review should distinguish the rule that matches the traffic from the interface that is ultimately selected. Valid forwarding also depends on destination route eligibility, current member state and the applicable SLA or quality-selection algorithm. A diagnostic showing configured members alone is not conclusive evidence that all those members will carry a particular flow. When troubleshooting, correlate the configured SD-WAN service with diagnose sys sdwan service4, the live session entry and the routing table. An application signature, an IP route and a health-check result describe different decision stages; treating them as interchangeable can produce incorrect conclusions about the egress interface. In the relevant Fortinet FortiOS documentation, the applicable feature should be verified against the deployed software version, the selected configuration mode and the live operational state before the answer is treated as a definitive implementation requirement.

The SD-WAN monitor’s table view in FortiManager provides a donut visualization plus a detailed table that shows each SD-WAN member’s status and SLA pass/miss, giving the per-member health view you’re after. FortiManager templates reduce repetitive work but must resolve to valid, device-specific configurations at installation time. Device assignments, metadata mappings, ADOM scope, policy-package interfaces and provisioning order should be inspected together rather than troubleshooting any one object in isolation. A successful management connection does not guarantee a successful configuration installation. Review the installation preview and task log, then validate the resulting device configuration and operational diagnostics. This separates a deployment-time validation failure from a live tunnel, routing or SLA fault. In the relevant Fortinet FortiManager documentation, the applicable feature should be verified against the deployed software version, the selected configuration mode and the live operational state before the answer is treated as a definitive implementation requirement. The status of individual overlay interfaces can be inspected separately.
