Fortinet Updated NSE7_FSN_AR-7.6 Exam Questions and Answers by bradley

The SD-WAN 7.6 Enterprise Administrator Study Guide states: “For branches and hubs, it creates BGP, IPsec, and CLI templates to accommodate all required configuration changes.”

Accordingly, the overlay orchestrator generates the following templates for each spoke:

The IPsec tunnel template configures the spoke as an IPsec dial-up client and applies the tunnel parameters appropriate to the selected topology, authentication method, routing design, and ADVPN settings.

The BGP template configures the spoke’s BGP routing, including the autonomous system, neighbor relationships, and either BGP-per-overlay or BGP-on-loopback behavior selected in the wizard.

The CLI template supplies additional configuration that cannot be represented entirely by the dedicated IPsec and BGP templates.

The guide separately explains that, for branch devices, FortiManager adds the required members and zones to the defined SD-WAN template. It does not generate a separate rules template for the spoke. Static routes are also not delivered through a dedicated static-route template; routing for the overlay is configured using the generated BGP template. Therefore, options A and E are incorrect.

The best verified answer is C .

The study guide says that when FortiGate is in conserve mode, it activates protection measures to recover memory space:

“System configuration cannot be changed”

“FortiGate skips quarantine actions (including FortiSandbox analysis)”

It also explains that inspection behavior can be reduced while in conserve mode:

“pass (default): All new sessions pass without inspection until FortiGate switches back to non-conserve mode.”

“The av-failopen setting also applies to flow-based antivirus inspection.”

The FortiOS administration guide summarizes this behavior as:

“This causes functions such as antivirus scanning to change how they operate to reduce the functionality and conserve memory without compromising security.”

That is why C is the closest correct choice: FortiGate can reduce functionality of some processes, especially antivirus-related inspection, to preserve memory.

Why the other options are wrong:

A is wrong because FortiGate does not automatically reboot as a default conserve-mode action. A reboot can be configured through an automation stitch , but that is an optional administrator-defined response, not the built-in conserve-mode behavior

B is wrong because the documentation does not say FortiGate switches from proxy-based inspection to flow-based inspection. Instead, it may pass traffic without inspection depending on av-failopen settings

D is not generally correct for conserve mode . The study guide says FortiGate starts dropping new sessions only when memory usage exceeds the extreme threshold : “If memory usage exceeds the extreme threshold, all new sessions that require inspection (flow-based or proxy-based) are blocked.”

So the verified answer is: C .
