FortiGate SD-WAN evaluates traffic against configured service rules and uses eligible member interfaces to determine the forwarding path. In this scenario, the destination is an internal corporate server accessible through the SD-WAN overlay.

The exhibit identifies SD-WAN service rule 3, named Corp , with the following configuration:

set load-balance enable

set mode sla

set dst " Corp-net "

set src " LAN-net "

set priority-members 3 4 5

Option D is correct because the rule enables SLA-based load balancing across three overlay members corresponding to HUB1-VPN1, HUB1-VPN2, and HUB1-VPN3.

The route-list output confirms that the corporate service rule has three available paths. Provided the members remain healthy, meet the applicable SLA requirements, and have valid destination reachability, FortiGate can distribute qualifying sessions among these interfaces.

Option B incorrectly assumes that the interface observed in the packet-sniffer output must carry every subsequent session. The displayed ICMP traffic uses HUB1-VPN3, but this observation does not establish exclusive forwarding for HTTP sessions.

Options A and C identify physical WAN interfaces rather than the eligible corporate VPN overlay members.

FortiGate applies the configured load-balancing algorithm when selecting an eligible member for a new session. The original question establishes that all SD-WAN links are stable, supporting the use of the available overlay paths.

The SD-WAN rule (config service edit 1) is configured with set mode priority. This means the rule selects the best interface based on a defined performance metric, as opposed to a simple static priority or SLA. The event log (image_41cfb5.png) shows Metric latency and Message Service prioritized by performance metric will be redirected in sequence order. This indicates that the rule is using latency to determine the preferred member. Given that the log message is about a change, and the most logical reason for a change in a priority mode is that a different member is now the best performer, it implies that the latency on port2 has become lower than that on port1. The log message Service prioritized by performance metric will be redirected in sequence order confirms that FortiGate is changing the member being used for this service. Because the mode is priority, FortiGate dynamically selects the member that currently meets the best performance criteria, which in this case is latency. The log implies a new member has been selected as the most optimal, and with the default configuration, the members are sorted based on their performance, so the outgoing interface list is effectively updated to prefer the new best-performing member (port2).

The zone setting advpn-select enable activates SD-WAN-aware ADVPN shortcut selection. The assigned advpn-health-check provides link metrics for evaluating available shortcut paths. The minimum-sla-meet-members value applies to zone-level SLA-compliant forwarding eligibility; it does not categorically mean shortcut negotiation is prohibited unless two members pass an SLA. Likewise, merely naming a health check does not impose a universal rule that every established shortcut must currently pass that health check. The candidate answer C confuses forwarding eligibility with IPsec ADVPN shortcut establishment. Reference: FortiOS 7.6 — ADVPN 2.0, advpn-select and minimum-sla-meet-members. 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.

Fortinet Secure SD-WAN supports an integrated networking architecture in which FortiGate appliances provide routing, traffic steering, and security enforcement while extending connectivity through FortiSwitch, FortiAP, and FortiExtender devices.

Option C is correct because a FortiGate configured as an SD-WAN hub can also utilize FortiExtender connectivity. FortiExtender provides cellular WAN transport, including 4G and 5G connectivity, and can be integrated as a logical WAN interface and SD-WAN member.

FortiSwitch provides wired access-layer connectivity through FortiLink, while FortiAP extends wireless LAN access. These components are complementary and do not require separate SD-WAN topologies.

Option A is incorrect because FortiGate devices supporting multiple extension types remain eligible for inclusion in the SD-WAN architecture.

Option B is incorrect because SD-WAN topology design is not restricted to a single extension product category. Multiple Fortinet networking components can be centrally orchestrated within the same deployment.

Option D is incorrect because regional segmentation is determined by network architecture, geographical requirements, routing domains, and operational considerations—not simply the types of extensions attached to each FortiGate.

FortiManager can centrally manage FortiGate devices and associated extensions, applying consistent SD-WAN templates and provisioning policies across enterprise branches and hubs.

MSSP-hosted hubs are generally appropriate where remote management and shared infrastructure are primary requirements. A customer-premises hub becomes valuable when corporate data center applications account for most branch traffic or when centralized internet security and egress are required at the customer site. Heavy interbranch traffic alone does not mandate a local hub because ADVPN shortcuts can bypass hubs. VoIP alone is likewise not decisive. Fortinet distinguishes secure internet access (SIA) from remote internet access (RIA); the phrase “SIA with centralized breakout” must be interpreted carefully. Remote breakout through the customer’s site corresponds to an RIA-type design, while SIA is a broader FortiSASE security service. In checking this outcome, an administrator should distinguish what the displayed exhibit proves from configuration prerequisites not visible in the screenshot. Routing eligibility, device role, rule matching, and software-version details should be verified before using the selected answer in a production decision. The referenced Fortinet documentation identifies the underlying feature and its supported configuration context.

Verification qualification: Option A conflates FortiSASE Secure Internet Access (SIA) with SD-WAN remote internet access (RIA).

FortiOS gathers performance statistics through configured health checks irrespective of whether a particular SD-WAN service rule currently uses the resulting SLA target. That makes option A incorrect. Lowest Cost (SLA) rules use selected SLA targets to determine which members satisfy their latency, jitter or packet-loss requirements; the standard distinction makes B and C the intended correct statements. A service can reference more than one SLA health check using separate entries in its service-level configuration, supporting the intended meaning of E. The CLI uses ' config system sdwan ' , ' config service ' , and a nested ' config sla ' table, in which each named health-check entry references an SLA ID. Option D suggests multiple target IDs within one entry; that is not what the standard syntax shows. Note that FortiOS versions supporting hybrid quality-and-SLA selection add nuance to the phrase ' only Lowest Cost ' , so B must be interpreted in the context of the conventional Manual, Best Quality and Lowest Cost strategies addressed by the question. The uploaded FortiSASE guides do not contain the detailed CLI target schema, which is documented in the FortiOS 7.6 SD-WAN command reference.

The question asks what must be done first before two existing physical interfaces can be moved into an SD-WAN zone. The exhibit shows firewall policies referencing port1 directly, and FortiOS does not permit firewall policies to continue referring to interfaces after those interfaces become SD-WAN members. Option D is therefore a reasonable practical first action: remove or modify the direct-interface firewall-policy references. However, the screenshot also shows static routes referencing the same interface. Those route references can likewise require adjustment. FortiOS does not establish a universal ordering that says firewall policies must always be modified before static routes; both changes may be required to complete the migration. Thus the single-answer design is ambiguous even though D is the preferred remediation in the previous review. The administrator should perform an interface-reference audit, move firewall policies to the intended SD-WAN zone, recreate appropriate zone-based static routes, and then configure the SD-WAN members. The default virtual-wan-link zone and other user-defined zones need not be deleted merely because an interface changes membership. The FortiOS 7.6 Members and Zones documentation establishes the relevant referencing restriction.

Verification qualification: Both firewall policy references and static-route dependencies may need changes; the mandated first action is ambiguous.

The requirement is to secure internet traffic generated by users behind an existing third-party branch router without necessarily installing FortiClient on individual endpoints.

Option D is correct because the FortiSASE Branch On-ramp subscription enables supported branch IPsec devices to establish encrypted connections to FortiSASE security points of presence.

With Branch On-ramp, the remote router forwards the branch ' s internet-bound traffic through an IPsec tunnel to FortiSASE, where cloud-delivered firewall, web filtering, application control, and other licensed security services can inspect the traffic.

FortiSASE supports the Custom device type for compatible third-party IPsec devices. These deployments use IKEv2 and appropriate tunnel parameters. Static routing is used for third-party branch devices where FortiSASE does not support BGP routing with that device type.

Option A is incorrect because SPA primarily provides access to private applications and corporate resources rather than establishing the required branch internet-security connection.

Option B does not correspond to the specific branch connectivity entitlement.

Option C is incorrect because secure web gateway functionality alone does not provision an IPsec on-ramp for the third-party router.

The applicable Branch On-ramp subscription and compatible FortiSASE base license must both be present. Exact entitlements depend on the FortiSASE release and subscription tier.

The FortiOS 7.6 architecture describes multiple standard SD-WAN deployment designs, each mapped to a specific operational goal or constraint. A cloud on-ramp topology is designed to optimize connectivity to cloud services such as SaaS and IaaS. This design provides the most efficient and reliable path to cloud applications by establishing direct tunnels to cloud gateways or cloud workloads and by avoiding backhauling traffic through a central data center. As a result, its primary indication is improving the performance of cloud applications, which makes option A correct. A remote breakout (centralized breakout) design forwards all internet-bound traffic from branch sites to a central hub for security inspection. This allows security policies, inspection, and logging to be centralized on a high-capacity FortiGate at the hub. Because branch devices do not need advanced local security configurations, this design also limits local management requirements, which makes option C correct. Option B is incorrect because a standalone SD-WAN design is not selected simply because a site has only one WAN link. SD-WAN provides its main benefits when multiple WAN paths exist, and single-link sites do not gain meaningful traffic-steering advantages. Option D is incorrect because a direct internet access (DIA) design performs local internet breakout at the branch and therefore requires strong local security capabilities. DIA does not inherently increase traffic security and is not intended for devices with limited capabilities. Therefore, the two correct associations are A and C.

The rule is in SLA mode with two SLAs. From the status, HUB1-VPN2 and HUB1-VPN3 meet the SLA (sla(0x2) and sla(0x3)), while HUB1-VPN1 does not (sla(0x0)). Among members that meet SLA, FortiGate uses the configured order (priority-members 4 5 6) to pick the first eligible one—HUB1-VPN2—so traffic is routed over HUB1-VPN2. 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.
