According to the FortiOS 7.6 Infrastructure study guide and Hardware Acceleration documentation, the Network Processor 7 (NP7) is the flagship hardware component designed to offload high-performance network traffic from the system CPU. A critical advancement of the NP7 over previous generations (such as the NP6) is its native support for Virtual eXtensible LAN (VXLAN) hardware acceleration.

In enterprise environments where VXLAN is used to extend Layer 2 segments over a Layer 3 network, the encapsulation and decapsulation of VXLAN headers can be computationally expensive. The NP7 provides specialized circuitry to perform these operations at line rate, significantly reducing latency and preventing CPU saturation. This allows the FortiGate to maintain high throughput even when handling complex overlay tunnels.

While the CP9 (Content Processor) (Option C) provides acceleration for SSL/TLS inspection and IPsec encryption, it does not handle network layer encapsulation like VXLAN. NTurbo (Option D) is a software feature that offloads firewall sessions to the network processors but is not a hardware chip itself. The SP5 (Option B) also supports VXLAN offloading in newer mid-range models, but the NP7 is the primary "specialized acceleration hardware" referenced for high-end enterprise performance in the 7.6 curriculum.

In this scenario, the corporate network and the new remote office network need to communicate over the Internet, which requires a secure and dynamic routing method. Since both networks are using OSPF (Open Shortest Path First) as the routing protocol, the best approach is to establish an OSPF over IPsec VPN to ensure secure and dynamic route propagation.

OSPF is already running on the corporate network, and extending it over an IPsec tunnel allows dynamic route exchange between the corporate FortiGate and the remote office FortiGate. IPsec provides encryption for traffic over the Internet, ensuring secure communication. OSPF over IPsec eliminates the need for manual static routes, allowing automatic route updates if networks change.

The new remote office's 192.168.1.0/24 subnet will be advertised dynamically to the corporate network without additional configuration.

The OSPF database optimization is necessary to reduce unnecessary routing information and improve network performance. In the given topology, Area 0.0.0.1 is a non-backbone area connected to Area 0.0.0.0 (the backbone area) through an Area Border Router (ABR).

To optimize OSPF in this scenario, configuring Area 0.0.0.1 as a Stub Area will:

● Reduce the size of the OSPF database by preventing external routes (from outside OSPF) from being injected into Area 0.0.0.1.

● Allow only intra-area and inter-area routes, meaning routers in Area 0.0.0.1 will rely on a default route for external destinations.

● Improve convergence time and reduce router processing load since fewer LSAs (Link-State Advertisements) are exchanged.

According to the Fortinet Security Fabric 7.6 documentation and FortiAnalyzer study materials, when multiple FortiGate devices are part of a Security Fabric, logs are typically sent to a centralized FortiAnalyzer for a unified view of the network.

In the provided exhibit, the topology shows HQ-NGFW-1 as the Fabric Root and HQ-ISFW as a downstream device. One of the key benefits of the Security Fabric (Option C) is topology-wide visibility, where logs from different devices are correlated.

The traffic log table shows a "Malware" action for traffic originating from 10.0.2.51 (located behind HQ-ISFW) destined for a public IP. If UTM is not enabled on the HQ-ISFW itself, it cannot generate an Antivirus (AV) log. However, because HQ-ISFW is part of the Security Fabric, the traffic eventually passes through the upstream device, HQ-NGFW-1, to reach the internet. If UTM is enabled on HQ-NGFW-1 (Option B), that device will inspect the traffic, detect the malware, and generate the security log. FortiAnalyzer then displays this log as part of the unified threat view, associating it with the original source and the inspection point in the fabric path.
