There are two deployment methods used to connect a FortiExtender as a FortiSASE LAN extension:

Connect FortiExtender to FortiSASE using FortiZTP:

FortiZero Touch Provisioning (FortiZTP) simplifies the deployment process by allowing FortiExtender to automatically connect and configure itself with FortiSASE.

This method requires minimal manual configuration, making it efficient for large-scale deployments.

Enter the FortiSASE domain name in the FortiExtender GUI as a static discovery server:

Manually configuring the FortiSASE domain name in the FortiExtender GUI allows the extender to discover and connect to the FortiSASE infrastructure.

This static discovery method ensures that FortiExtender can establish a connection with FortiSASE using the provided domain name.

In FortiSASE, the accuracy of application usage reports depends on two primary factors: the ability to identify the application (visibility) and the configuration to log that data (reporting).

Deep Inspection Requirement (D): Modern applications frequently use encryption (SSL/TLS) and dynamic ports. Without Deep Inspection (SSL decryption), the FortiSASE security engine cannot see the application payload and is limited to inspecting headers or SNI. This results in many applications being identified only by their generic protocol (e.g., " SSL " or " HTTPS " ) and subsequently appearing as Unknown in reports because the specific Layer 7 application signature cannot be matched.

Application Control Monitor Setting (B): Even when an application is correctly identified, it must be properly logged to appear accurately in the " Daily report for application usage " . In the inline-CASB (Application Control) profile, categories are assigned actions such as " Allow " , " Block " , or " Monitor " . If categories are set to " Allow " instead of Monitor , the traffic is permitted but granular session details—including the specific application category—may not be logged for reporting purposes, causing them to be grouped into an " Unknown " or " Uncategorized " bucket in high-level summaries.

Analysis of Incorrect Options:

Option A: While certificate inspection provides more visibility than no inspection, it is still insufficient for many applications that require deep packet inspection for identification. Therefore, the lack of Deep inspection (Option D) is the more accurate technical explanation for " Unknown " results.

Option C: ZTNA tags are used for access control and posture-based policy enforcement; they do not impact the application identification engine ' s ability to categorize traffic flows.

In FortiSASE Secure Private Access (SPA) deployments, establishing a stable connection between the FortiSASE PoPs and the corporate FortiGate hub relies on two primary layers: the IPsec Tunnel and the BGP Peering .

Exhibit Analysis: The exhibit (image_577e17.jpg) shows the status of several Security PoPs (Singapore, Tokyo, Frankfurt, and San Jose) connected to an " FGT-Hub " .

Tunnel Status vs. BGP Status: For all listed PoPs, the Health Check IP Status and Tunnel status are both shown with a green " Up " icon. This confirms that the underlying IPsec connectivity and the physical path between the SASE cloud and the hub are functioning correctly.

Identifying the Failure: The BGP Peering State is reported as Active . In BGP terminology, the " Active " state specifically indicates that the router is attempting to initiate a TCP connection with its peer but has not yet received a response. A fully functional and successful BGP connection must reach the Established state.

Root Cause Determination: Since the tunnel is up (eliminating Gateway or Authentication Method issues as the primary suspects) but the BGP state remains stuck in " Active, " the most likely cause is a mismatch or misconfiguration in the BGP Peer IP or BGP neighbor settings. This prevents the exchange of routing information necessary for users to access private applications.

To resolve the connectivity problem, the administrator must ensure that the BGP neighbor IPs configured on the FortiGate hub match those assigned by the FortiSASE orchestration and that firewall policies on the hub allow BGP traffic (TCP port 179) across the tunnel.

In FortiSASE, the requirement to redirect specific traffic away from the secure tunnel and through the local physical interface is achieved through Steering Bypass (commonly referred to as split tunneling).

Steering Bypass Destinations: This feature is configured within the Endpoint Profile settings. When an administrator adds a destination (such as the Google Maps URL or FQDN) to the Steering Bypass table, the FortiClient agent updates the local routing table on the endpoint.

Traffic Redirection: Traffic matching these bypass rules is explicitly excluded from the FortiSASE VPN tunnel and instead sent directly out of the device ' s local internet gateway (physical interface). This is ideal for optimizing bandwidth and reducing latency for trusted, high-volume applications like mapping services or video conferencing.

Analysis of Other Options:

Option A: ZTNA TCP access proxy rules are designed for secure access to private applications, not for managing how internet-bound traffic is routed.

Option B: While it uses the term " steering bypass, " there is no " tunnel firewall policy " configuration for this purpose; the configuration is done at the endpoint profile level.

Option C: Exempting a URL in the Web Filter profile only instructs FortiSASE to skip security scanning (AV, DLP, etc.) for that traffic. The traffic would still be encapsulated in the tunnel and sent to FortiSASE, which does not meet the requirement to redirect it to the physical interface.

By configuring the Google Maps URL as a steering bypass destination , the organization ensures the traffic never enters the SASE tunnel, fulfilling the requirement for both traffic inspection (for all other traffic) and local redirection (for Google Maps).

The Secure Web Gateway (SWG) policy is used to control traffic between the FortiClient endpoint and FortiSASE for secure internet access. SWG provides comprehensive web security by enforcing policies that manage and monitor user access to the internet.

Secure Web Gateway (SWG) Policy:

SWG policies are designed to protect users from web-based threats and enforce acceptable use policies.

These policies control and monitor user traffic to and from the internet, ensuring that security protocols are followed.

Traffic Control:

The SWG policy intercepts all web traffic, inspects it, and applies security rules before allowing or blocking access.

This policy type is crucial for providing secure internet access to users connecting through FortiSASE.

The correct answer is D . The FortiSASE study guide explains that SPA allows a FortiSASE POP to act as a spoke and connect to a FortiGate hub. It states that you can use FortiSASE SPA so that a POP connects to either a standalone hub using IPsec or to an existing Fortinet SD-WAN deployment . It also states that the BGP protocol is established through IPsec links for dynamic route exchange, which gives FortiSASE remote users access to private resources. For hub deployments running FortiOS 7.4.5 or later, the guide explains that an easy configuration key can simplify SPA setup on FortiSASE by automatically populating key fields in the FortiGate hub configuration.

The wrong options contradict the guide. Option A is false because FortiSASE does not apply SNAT for remote VPN user and edge device traffic destined for SPA hubs, and FortiSASE spokes support IKEv2, not IKEv1. Option B confuses agentless ZTNA with SD-WAN private access. Option C is wrong because SPA uses IPsec and BGP, and the easy configuration key is for SPA hub setup, not for securing general web traffic.

In the FortiSASE architecture, Network Lockdown is a security feature designed to prevent off-net (off-fabric) endpoints from accessing the internet or local network without the protection of the SASE security stack.

Triggering Lockdown: When an endpoint is determined to be " off-net " —meaning it does not satisfy the on-net rule sets defined in its endpoint profile—a timer starts for a configurable grace period .

Function of the Grace Period: During this period, the endpoint maintains full access to the LAN and the internet. 4 The specific purpose of this grace period is to provide the user with a window of time to attempt a connection to the FortiSASE VPN tunnel or an alternate corporate tunnel. 5 This ensures that users can authenticate and regain a secure " on-net " status before any connectivity restrictions are enforced.

Enforcement: If the grace period expires and the endpoint has failed to establish a VPN connection, FortiClient enforces a strict lockdown. 7 In this state, the device cannot reach the LAN or the internet, except for specifically defined " Exempt Destinations " (such as captive portal login pages or the FortiSASE portal itself).

Resetting the Timer: Any attempt to connect to the tunnel during the grace period resets the timer, providing additional opportunities for the user to remediate their connection status. 8

According to the FortiSASE 25 Administrator Study Guide , the grace period is an essential user-experience setting that balances strict " zero-trust " security with the practical need for users to access the network briefly to establish their secure tunnel.

Integrating FortiManager with FortiSASE allows for central management of configuration objects like addresses and 5 security 6 profiles. For this integration to function correctly, the following key prerequisites must be met:

Same FortiCloud Account: A fundamental requirement for the integration is that both 10 the FortiSASE instance and the FortiManager (whether physical, VM, or Cloud) must be registered under the same FortiCloud (FortiCare) account . This common identity allows the platforms to securely discover and authorize each other for synchronization.

Supported Firmware Version: The FortiManager must run a firmware version that is compatible with the FortiSASE release. According to the FortiSASE 25 Enterprise Administrator Study Guide , FortiManager version 7.4.4 or later is generally required to support the specific API connectors and object synchronization logic used by current FortiSASE environments. Using an unsupported version may result in synchronization failures or missing configuration features.

Management Logic: Once these prerequisites are met, the administrator can enable " Central Management " in the FortiSASE portal. This creates a one-way synchronization where FortiManager acts as the source of truth for objects like Security Profile Groups, ensuring consistent security posture across both the SASE cloud and on-premises FortiGates.

FortiSASE uses the following components for application control to act as an inline-CASB (Cloud Access Security Broker):

SSL Deep Inspection:

SSL deep inspection is essential for decrypting and inspecting HTTPS traffic to identify and control applications and data transfers within encrypted traffic.

This allows FortiSASE to enforce security policies on SSL/TLS encrypted traffic, providing visibility and control over cloud applications.

Web Filter with Inline-CASB:

The web filter component integrates with inline-CASB to monitor and control access to cloud applications based on predefined security policies.

This combination provides granular control over cloud application usage, ensuring compliance with security policies and preventing unauthorized data transfers.

To meet the requirement of inspecting all endpoint internet traffic on FortiSASE while excluding Google Maps traffic from the FortiSASE VPN tunnel and redirecting it to the endpoint ' s physical interface, you should configure split tunneling. Split tunneling allows specific traffic to bypass the VPN tunnel and be routed directly through the endpoint ' s local interface.

Split Tunneling Configuration:

Split tunneling enables selective traffic to be routed outside the VPN tunnel.

By configuring the Google Maps Fully Qualified Domain Name (FQDN) as a split tunneling destination, you ensure that traffic to Google Maps bypasses the VPN tunnel and uses the endpoint ' s local interface instead.

Implementation Steps:

Access the FortiSASE endpoint profile configuration.

Add the Google Maps FQDN to the split tunneling destinations list.

This configuration directs traffic intended for Google Maps to bypass the VPN tunnel and be routed directly through the endpoint ' s physical network interface.
