Q21. An administrator has decreased all the TCP session timers to optimize the FortiGate memory usage. However, after thechanges, one network application started to have problems. During the troubleshooting, the administrator noticed that the FortiGate deletes the sessions after the clients send the SYN packets and before the arrival of the SYN/ACKs. When the SYN/ACK packetsarrive to the FortiGate, the unit has already deleted the respective sessions. Which TCP session timer must be increased to fix this problem?
A. TCP half open.
B. TCP half close.
C. TCP time wait.
D. TCP session time to live.
Answer: D
Q22. Examine the partial output from the IKE realtime debugshown in the exhibit; then answer the question below.
Why didn't the tunnel come up?
A. IKE mode configuration is not enabled in the remote IPsec gateway.
B. The remote gateway's Phase-2 configuration does not match the local gateway's phase-2configuration.
C. The remote gateway's Phase-1 configuration does not match the local gateway's phase-1 configuration.
D. One IPsec gateway is using main mode, while the other IPsec gateway is using aggressive mode.
Answer: B
Q23. Examine the IPsec configuration shown in the exhibit; then answer the question below.
An administrator wants to monitor the VPN byenable the IKE real time debug using these commands:
diagnose vpn ike log-filter src-addr4 10.0.10.1 diagnose debug application ike -1 diagnose debug enable
The VPN is currently up, there is no traffic crossing the tunnel and DPD packets are being interchanged between both Ipsec gateways. However, the IKE rea time debug does NOT show any output. Why isn't there any output?
A. The IKE real time debug shows the phases 1 and 2 negotiations only. It does not show any more output once the tunnel is up.
B. The log-filter setting is set incorrectly. The VPN's traffic does not match this filter.
C. The IKF real time debug shows the phase 1 negotiation only. For information after that, the administrator must use the IPsec real time debug instead: diagnosedebug application ipsec -1
D. The IKE real time debug shows error messages only. If it does not provide any output, it indicates that the tunnel is operating normally.

What should the administrator check?
