Sample Questions
Choose an answer and explore the explanation to see how practice works.
A partner behind NAT connects to the Anchorage branch IPsec VPN. IKE starts on UDP/500 but fails after NAT is detected. Which capability must be allowed through the path? Case reference: FOS76-142.
Guests at the Anchorage branch must authenticate in a browser before internet access, while domain laptops continue using FSSO. Which policy design fits the guest requirement? Case reference: FOS76-070.
After an FGCP failover at the Anchorage branch, upstream switches briefly keep sending frames toward the failed primary. Which FortiGate behavior updates adjacent Layer 2 forwarding after the secondary becomes primary? Case reference: FOS76-013.
At the Anchorage branch, an administrator can manage FortiGate from any address after enabling HTTPS on wan1. The security team wants only the jump subnet 10.24.10.0/24 to authenticate to that admin account. Which setting best enforces that account-level restriction? Case reference: FOS76-004.
The Reno warehouse has two default static routes through port1 and port2. Both have distance 10, but the route through port1 has priority 5 and port2 has priority 20. Which route is preferred? Case reference: FOS76-110.
