A customer wants to ensure secure access to private applications for their users by replacing...

The correct answers are C. Secure SD-WAN and D. Zero trust network access (ZTNA) . In FortiSASE, secure access to private applications is part of Secure Private Access (SPA) . The study guide identifies ZTNA as the SASE technology that provides “secure, explicit, identity-based access,” and explains that applying ZTNA shifts implicit access to explicit control by combining user authentication, continuous identity, context validation, and integration. This directly supports replacing traditional VPN access for private applications.

The guide also states that organizations can integrate FortiSASE with existing FortiGate SD-WAN deployments “to provide remote users access to private resources,” where FortiSASE security POPs act as spokes to the FortiGate SD-WAN hub. In the SPA section, FortiSASE private access is described as using ZTNA and SD-WAN integration for secure cloud and data center application access. SWG and CASB are not the best answers because SWG is for secure internet/web access, while CASB focuses on SaaS visibility and data protection, not private application VPN replacement. SD-WAN on-ramp is a deployment method, not the core SASE technology pair asked for here.
