NSE7_EFW-6.2 Online Practice Questions and Answers

Examine the IPsec configuration shown in the exhibit; then answer the question below. Questions and Answers PDF P-3

An administrator wants to monitor the VPN by enabling 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 real time debug does NOT show any output.

Why isn't there any output?

A. The IKE real time 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 IKE real time debug shows the phase 1 negotiation only. For information after that, the administrator must use the IPsec real time debug instead: diagnose debug 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.

Which of the following statements are true regarding the SIP session helper and the SIP application layer gateway (ALG)? (Choose three.)

A. SIP session helper runs in the kernel; SIP ALG runs as a user space process.

B. SIP ALG supports SIP HA failover; SIP helper does not.

C. SIP ALG supports SIP over IPv6; SIP helper does not.

D. SIP ALG can create expected sessions for media traffic; SIP helper does not.

E. SIP helper supports SIP over TCP and UDP; SIP ALG supports only SIP over UDP.

An administrator has decreased all the TCP session timers to optimize the FortiGate memory usage. However, after the changes, 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 packets arrive 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.

The logs in a FSSO collector agent (CA) are showing the following error: failed to connect to registry: PIKA1026 (192.168.12.232)

What can be the reason for this error?

A. The CA cannot resolve the name of the workstation.

B. The FortiGate cannot resolve the name of the workstation.

C. The remote registry service is not running in the workstation 192.168.12.232.

D. The CA cannot reach the FortiGate with the IP address 192.168.12.232.

A FortiGate is rebooting unexpectedly without any apparent reason. What troubleshooting tools could an administrator use to get more information about the problem? (Choose two.)

A. Firewall monitor.

B. Policy monitor.

C. Logs.

D. Crashlogs.

C. diagnose sniffer packet any `esp'

D. diagnose sniffer packet any `udp port 500 or udp port 4500'

An administrator has configured the following CLI script on FortiManager, which failed to apply any changes to the managed device after being executed.
