FCSS_SDW_AR-7.4 Exam Dumps : FCSS - SD-WAN 7.4 Architect

For SD-WAN deployments that span multiple regions—where most traffic is intra-region and there is no requirement for inter-region ADVPN—the best practice is to use IBGP with BGP on loopback interfaces for routing within each region and EBGP between the regions. This approach ensures robust and scalable routing, isolates regional routing domains, and enables policy control at region boundaries. BGP on loopback is preferred for its reliability and flexibility, as it enables peering that is not tied to specific physical interfaces. EBGP between regions allows each region to maintain independent routing policies and summarization, optimizing performance and manageability. By separating IBGP (intra-region) and EBGP (inter-region), you create a modular architecture that scales easily and simplifies fault isolation and troubleshooting.

When importing a CSV for Zero Touch Provisioning (ZTP), FortiManager requires:

"Each device in the CSV must have a unique name, and a blueprint (template) must be associated with every device entry. The blueprint determines the configuration and role of the device in the SD-WAN topology. Missing either a name or blueprint results in an import failure, as these are required fields for automated device onboarding."

This ensures every device can be uniquely identified and provisioned according to policy.

The provisioning templates in FortiManager are designed for flexible, scalable configuration of large SD-WAN deployments. The official documentation explains:

"Template groups can consist of both system and SD-WAN templates, providing a way to apply consistent settings across multiple devices. CLI templates are evaluated and executed in order from top to bottom within the template group, which is crucial for managing dependencies. Furthermore, CLI template groups can contain both regular CLI templates and advanced (Perl-script-based) templates, allowing complex or conditional configuration logic."

This modular design streamlines large deployments by separating system, SD-WAN, and CLI logic into reusable building blocks.
