SD-WAN architecture, traffic engineering, and configuration typically represent 40-50% of exam content. Troubleshooting and performance monitoring account for another 25-30%, while security integration and advanced failover scenarios round out the remaining questions. Focus your study time proportionally and ensure you can not only configure but also diagnose and optimize SD-WAN deployments.
Understanding topology choices (hub-and-spoke vs. mesh) directly informs how you configure interfaces, define WAN links, and set up traffic policies in FortiGate. For example, a mesh design requires more complex policy rules and link quality thresholds than a hub-and-spoke model. The exam tests whether you can move fluidly from architectural decisions to hands-on implementation.
Practical experience configuring FortiGate SD-WAN in a lab or test environment is invaluable. Prioritize: setting up multiple WAN links, creating traffic engineering policies, monitoring link health, and simulating failover scenarios. Even virtual labs help you develop muscle memory for the FortiGate interface and deepen your understanding of how configuration changes affect network behavior.
Candidates often confuse policy-based routing with standard routing, misunderstand link quality metrics (latency vs. jitter), or overlook security implications of multi-path designs. Another frequent error is selecting a correct concept but missing the specific FortiGate syntax or parameter name. Read each question carefully, eliminate obviously wrong answers first, and when in doubt, choose the option that addresses both functionality and security.
Dedicate your final week to full-length practice tests and targeted review of weak areas rather than re-reading notes. Take at least one timed mock exam under exam conditions (quiet room, no interruptions) to build confidence and identify pacing issues. On exam day, read questions thoroughly before answering, flag uncertain items for review, and manage your time so you have 2-3 minutes per question on average.
You are tasked with configuring ADVPN 2.0 on an SD-WAN topology already configured for ADVPN. What should you do to implement ADVPN 2.0 in this scenario?
Refer to the exhibit, which shows the SD-WAN rule status and configuration.
Based on the exhibit, which change in the measured latency will first make HUB1-VPN3 the new preferred member?
The rule is in priority mode with HUB1-VPN1 (seq 4) as the first preferred member, HUB1-VPN2 second, and HUB1-VPN3 third. Latency itself does not cause HUB1-VPN3 to become preferred unless a higher-priority member fails SLA. If HUB1-VPN1's latency exceeds the SLA threshold (here simulated by latency reaching 200 ms), FortiGate stops using it and moves down the priority list. That is when HUB1-VPN3 could become the active path.
When a customer delegate the installation and management of its SD-WAN infrastructure to an MSSP, the MSSP usually keeps the hub within its infrastructure for ease of management and to share costly resources.
In which two situations will the MSSP install the hub in customer premises? (Choose two.)
Refer to the exhibit.
Based on the output shown in the exhibit, what can you conclude about the device role and how it handles health checks? Choose one answer.)
Exhibit.
The administrator configured the IPsec tunnel VPN1 on a FortiGate device with the parameters shown in exhibit.
Based on the configuration, which three conclusions can you draw about the characteristics and requirements of the VPN tunnel? (Choose three.)
This configuration demonstrates a typical IPsec setup for SD-WAN overlays where the hub side requires a manually defined tunnel IP address, and the spoke can be flexibly configured, including interoperability with third-party IPsec devices. As described in the Fortinet SD-WAN Architect Guide: ''For some overlays, the tunnel interface IP is configured statically on the hub side, which allows more control over overlay subnetting and facilitates the use of user-defined overlay IP addresses. This approach is also a requirement for compatibility with non-FortiGate endpoints, such as third-party IPsec devices that may not support dynamic address assignment via IKE or proprietary mechanisms.'' This enables hybrid SD-WAN environments and advanced designs involving external partners or cloud services. Overlay IP flexibility is critical for route control and segmentation. Reference:
