NSE7_FSN_AR-7.6 Exam Dumps - Fortinet NSE 7 Network Security Architect Questions and Answers

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 correct answer is C. The session is offloaded using NPU.

The exact session example in the study guide shows:

proto=6 → this is a TCP session

expire=3599 → the session will expire in 3599 seconds, not in one second

hook=post dir=org act=snat 10.9.31.117:45388- > 200.8.57.5:443(10.1.0.3:45388)

hook=pre dir=reply act=dnat 200.8.57.5:443- > 10.1.0.3:45388(10.9.31.117:45388)

npu info: ... offload=8/8 ...

and the slide explicitly states: “Offloaded in both directions using NP6”

The study guide also explains this exact point clearly:

“Counters for hardware acceleration—The presence of the npu info field indicates the session has been offloaded to hardware acceleration. In this example, traffic is being offloaded in both directions using network processor (NP) 6, which is represented by the value of 8.”

Why the other options are wrong:

A is wrong because expire=3599, not 1. The duration=1 field means the session has existed for 1 second, not that it will expire in 1 second.

B is wrong because the original session is from 10.9.31.117 to the remote server 200.8.57.5:443. The IP 10.1.0.3 is the SNAT-translated source address, not the final destination.

D is not the best answer for this single-select question. The reply is indeed DNATed back toward the original client, but the exact validated takeaway highlighted by the study guide for this exhibit is the NPU offload state.

The output explicitly states This router is an ABR. An OSPF area border router has interfaces participating in multiple OSPF areas and provides connectivity between those areas and the backbone. Therefore, A is correct.

The output also states that the RFC1583Compatibility flag is enabled. The Enterprise Firewall 7.6 Administrator Study Guide explains that FortiGate can use RFC 1583-compatible OSPF path selection for ECMP, where eligible external routes of equal cost can be installed concurrently. This makes D correct.

Nothing in the displayed status identifies the FortiGate as a backup designated router, so B cannot be concluded. Option C describes an autonomous system boundary router (ASBR), which originates external LSAs when redistributing routes into OSPF. Being an ABR does not by itself mean the router is injecting external routing information.

================

The session output includes the flags:

state=redir local may_dirty ...

npu_state=00000000

offload=0/0

The 7.6 study guide explains these flags directly:

local = “Session is to/from local stack”

redir = “Session is being processed by an application layer proxy”

may_dirty = “Session is allowed by a firewall policy”

This makes C correct, because the local flag means the session either originates from FortiGate or terminates on FortiGate. The FortiOS administration guide states the same meaning: “Session is originated from or destined for local stack.”

This also makes A correct. The redir flag means the session is handled by an application-layer proxy. FortiOS documents explain that proxy-based inspection buffers traffic on the FortiGate and inspects it there, and that proxy-based processing is CPU and memory-intensive

Since the session also shows no NPU offload (npu_state=00000000, offload=0/0), this traffic is being handled in software/CPU, not by the NPU.

Why the other options are wrong:

B is wrong because the redir flag proves the session is not passing without inspection; it is being processed by an application-layer proxy

D is wrong because there is no authentication flag in this session. In Fortinet examples of captive portal/authentication-related sessions, the session state includes auth or authed flags. The study guide shows: “Any session for traffic coming from an authenticated user contains the authed flag.” This exhibit does not show auth or authed, so there is no basis to conclude the client was redirected to a captive portal for authentication.

Fortinet distinguishes measured link-quality metrics from SLA targets. Best performance, called Best Quality in current FortiOS terminology, compares member performance using a selected quality criterion; it does not use an SLA target as the eligibility mechanism. Thus, A is correct.

SLA-target eligibility belongs to the Lowest Cost (SLA) strategy, including Lowest Cost with load balancing, making D correct. When an SD-WAN rule references a particular performance SLA, it selects one SLA target ID from that performance SLA, so E is also correct. Additional performance SLAs can be referenced separately, but multiple target IDs from the same SLA are not selected simultaneously in that rule reference.

Option B confuses measurement with eligibility. Performance SLA processes measure member metrics independently; configuring an SLA target supplies thresholds against which those measurements are evaluated. Consequently, B and C are incorrect.

Comprehensive and Detailed 100 to 150 words of Explanation From Secure Networking Architect Study Guides topics:

The MAC prefix 00:09:0f:09 identifies FortiGate ' s logic-2 HA virtual-MAC construction. The Enterprise Firewall 7.6 guide states that logic 2 applies when the virtual-cluster ID is 0 or 1, the HA group ID is below 256, and the physical-interface index is below 128.

In 00:09:0f:09:18:81, hexadecimal 18 represents HA group ID 24, confirming that the group ID is below 255 and making D correct. The high bit in the final octet indicates virtual-cluster ID 1; this means virtual clustering/VDOM functionality is involved, making C correct. The remaining physical-index bits identify index 1, not 2, eliminating A. This virtual-MAC construction belongs to FortiGate Clustering Protocol HA operation and does not establish that the device uses standalone FGSP session synchronization, eliminating B.

" FortiManager offers two approaches to configuring SD-WAN: per-device management and central management. "

The guide also states:

" In per-device management, you configure SD-WAN settings for individual devices. "

Technical Explanation:

FortiManager supports two management approaches for SD-WAN deployments: per-device configuration and centralized SD-WAN management.

Option C is correct because the devices are already managed by FortiManager, and the administrator only needs to configure SD-WAN on a limited number of standalone FortiGate devices.

With per-device management, administrators can configure settings individually through Device Manager without migrating devices to a separate SD-WAN management workflow.

The administrator can access these settings through:

Device Manager → Select Managed FortiGate → Network → SD-WAN

From this interface, administrators can configure SD-WAN zones, members, performance SLAs, and SD-WAN rules according to each device ' s requirements.

The configuration changes are subsequently installed on the managed FortiGate.

Why the other options are incorrect:

Option A: Moving devices into the SD-WAN Manager workflow and using a standalone wizard is not mandatory for basic per-device configuration.

Option B: A dedicated device group is not required simply to configure SD-WAN settings on individual devices.

Option D: FortiManager supports per-device SD-WAN rule configuration without requiring SD-WAN Manager enrollment.

Architectural Consideration:

Centralized SD-WAN management becomes particularly valuable in large deployments requiring consistent templates, automation, and overlay orchestration. However, for a small environment with distinct device configurations, per-device management remains a supported and practical approach.
