Fortinet FCSS_SASE_AD-25 FCSS - FortiSASE 25 Administrator Exam Practice Test

The Digital Experience Monitor (DEM) in FortiSASE measures and monitors network performance from the FortiSASE Points of Presence (PoPs) to specific SaaS or cloud applications, helping identify and troubleshoot performance issues across the service path.

The secure web gateway (SWG) serves as the cloud-based proxy that inspects and controls web traffic, replacing the on-premises proxy. The inline-CASB provides additional visibility and control over cloud application usage, enhancing security in hybrid environments.

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.

According to the FortiOS Administration Guide, when configuring central management, a FortiManager Cloud entitlement must be present and the devices must share the same FortiCloud account for registration. Specifically:

“The FortiManager Cloud button can only be selected if you have a FortiManager Cloud product entitlement.”

“The FortiGate and FortiCloud license are registered to the same account.”

Thus, the two verified requirements are: B (entitlement) and D (same FortiCloud account).

ZTNA enforces least-privileged access by verifying user identity and device posture before granting access to specific corporate applications, even when protected by an on-premises FortiGate.

FortiSASE inline-CASB operates in the traffic path to provide real-time visibility and control over data in motion as it is transmitted to and from cloud applications.

Zero-trust tags assess endpoint compliance based on defined posture rules and are used in access policies to control whether a device is permitted or denied access to specific network resources.

FortiSASE uses ZTNA tags to assess the endpoint’s security posture. If the posture is non-compliant based on predefined rules, FortiSASE enforces network lockdown to restrict access accordingly.

To enable the MSSP feature on FortiSASE, you must use the FortiCloud IAM portal to assign RBAC permissions to users. This grants appropriate access to manage multiple tenants or customer accounts securely.

A PAC file is used to redirect client web traffic through the SWG, and FortiClient software is required to connect endpoints to the FortiSASE service for secure internet access (SIA).

The FortiSASE software installations page shows which endpoints have specific software installed, allowing administrators to monitor potentially unwanted applications across the network.

The bookmark portal is the recommended method for providing contractors access to private web applications through FortiSASE Secure Private Access, as it offers a user-friendly, secure, and controlled access mechanism without requiring full network connectivity.

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

Assigning hubs with different priorities in a FortiSASE SD-WAN deployment allows traffic to be routed through the optimal hub to meet SLA requirements and ensures redundancy by enabling automatic failover if the preferred hub becomes unavailable.

To enforce device posture checks and ensure that TCP traffic flows through FortiGate, the FortiGate must act as a ZTNA access proxy and host the ZTNA servers and policies. This setup allows posture validation via FortiSASE while routing traffic securely to protected servers through FortiGate.
