According to the FortiSASE 7.6 Architecture Guide and the FCP - FortiSASE 24/25 Administrator study materials, the FortiSASE solution is structured around three primary pillars or " use cases " that address the security requirements of a modern distributed workforce.

Secure Internet Access (SIA) (Option A): This use case focus on protecting remote users as they browse the public internet. It utilizes a full cloud-delivered security stack including Web Filtering, DNS Filtering, Anti-Malware, and Intrusion Prevention (IPS) to ensure that users are protected from web-based threats regardless of their physical location.

Secure SaaS Access (SSA) (Option B): This use case addresses the security of cloud-based applications (like Microsoft 365, Salesforce, and Dropbox). It leverages Inline-CASB (Cloud Access Security Broker) to identify and control " Shadow IT " —unauthorized cloud applications used by employees—and applies Data Loss Prevention (DLP) to prevent sensitive information from being leaked into unsanctioned SaaS platforms.

Secure Private Access (SPA) (Option C): This use case provides secure, granular access to private applications hosted in on-premises data centers or private clouds. It can be achieved through two main methods: ZTNA (Zero Trust Network Access), which provides session-specific access based on identity and device posture, or through SD-WAN integration, where the FortiSASE cloud acts as a spoke connecting to a corporate SD-WAN Hub.

Why other options are incorrect:

Secure VPN Access (SVA) (Option D): While SASE uses VPN technology (SSL or IPsec) as a transport for the Endpoint mode, " SVA " is not a formal curriculum-defined use case. The SASE framework is intended to evolve beyond traditional " Secure VPN Access " into the SIA and SPA models.

Secure Browser Access (SBA) (Option E): Although FortiSASE offers Remote Browser Isolation (RBI), it is considered a feature or a component of the broader Secure Internet Access (SIA) use case rather than a separate, standalone use case in the core administrator curriculum.
