Fortinet FCSS - FortiSASE 25 Administrator FCSS_SASE_AD-25 Exam Dumps: Updated Questions & Answers (October 2025)

The FortiClient Administration Guide states that on-net rules determine when an endpoint is in a trusted location. If the endpoint matches the configured subnet, the client is considered on-net, and therefore bypasses auto-connect.

“Device registration and on-net status information for a device that is running FortiClient appears only on the FortiGate that applies the FortiClient profile to that device.”

Since 192.168.13.101 falls inside the trusted subnet 192.168.13.0/24, the endpoint is treated as on-net → it will be exempted from auto-connect.

In FortiSASE, Single Sign-On (SSO) takes precedence and overrides other configured user authentication methods, ensuring a centralized and streamlined authentication process across services.

Fortinet documentation makes clear that overlay IDs must be identical on hub and spoke for ADVPN to establish correctly:

“When configuring the root and downstream FortiGates the Fabric Overlay Orchestrator configures… IPsec overlay configuration (hub and spoke ADVPN tunnels).”

“The Fabric root will be the hub and any first-level downstream devices from the Fabric root will be spokes.”

In the scenario:

FortiSASE overlay ID = 100

FortiGate hub overlay ID = 101

Mismatch prevents tunnel establishment. Therefore, the fix is: B. The network overlay ID must match on FortiSASE and the hub.

Deploying secure private access with SD-WAN enables the hub FortiGate to perform ZTNA posture checks, and supports both TCP and UDP applications over the tunnel, allowing for flexible and secure access to internal resources.

When FortiClient is integrated with FortiSASE, it enables vulnerability management and device posture checks, allowing for advanced endpoint compliance enforcement - capabilities not available in standalone secure web gateway (SWG) deployments.

Single Sign-On (SSO) overrides any other previously configured user authentication method on FortiSASE, taking precedence for user authentication.

The self-registration portal is the recommended method for granting temporary internet access to contractors or guests. It provides a simple and secure way for the contractor to authenticate and access the internet without requiring full endpoint management or policy configuration.

Although the antivirus is installed, it is not running due to the Windows application firewall blocking it. According to the FortiSASE-Non-Compliant rule, antivirus software must be both installed and running. Since this condition fails, FortiClient assigns the FortiSASE-Non-Compliant tag to the endpoint.
