What action should be taken to optimize traffic routing in FortiSASE?

Implementing a dynamic routing protocol is the most effective action to optimize traffic routing in FortiSASE. Dynamic routing protocols automatically adjust and optimize the paths that data packets take across networks based on the current network conditions. This leads to more efficient use of bandwidth and overall improved performance, as dynamic protocols can quickly react to network changes or congestion, ensuring that traffic takes the most efficient path.

In contrast, manual configuration for each connection can be time-consuming and may not adapt well to changing network environments, making it less optimal for dynamic traffic conditions. Restricting all access to predefined paths limits flexibility and can lead to inefficiencies in routing, as traffic may not follow the most efficient path available. Blocking all VPN traffic might streamline performance in certain situations but could also lead to critical connectivity issues for users and applications that rely on VPNs for secure access, ultimately hindering overall network functionality and user experience.
