Question 1
Single choice

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.

Question 2
Single choice

Examine the IPsec configuration shown in the exhibit; then answer the question below.

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.

Question 3
Multiple choice

View the exhibit, which contains the partial output of an IKE real-time debug, and then answer the question below.

Which statements about this debug output are correct? (Choose two.)

A.

The remote gateway IP address is 10.0.0.1.

B.

It shows a phase 1 negotiation.

C.

The negotiation is using AES128 encryption with CBC hash.

D.

The initiator has provided remote as its IPsec peer ID.

Question 4
Single choice

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

Why didn't the script make any changes to the managed device?

A.

Commands that start with the # sign are not executed.

B.

CLI scripts will add objects only if they are referenced by policies.

C.

Incomplete commands are ignored in CLI scripts.

D.

Static routes can only be added using TCL scripts.

Question 5
Multiple choice

You have configured FortiManager as a local FDS to provide FortiGate AV and IPS updates, but FortiGate devices are not receiving updates to their AV signature databases, IPS engines, or IPS signature databases.

Which two settings need to be verified for these features to function? (Choose two.)

A.

FortiGate needs to have the server list entry for FortiManager set to server-type update under config system central-management.

B.

FortiManager needs to be the license validation server for FortiGate devices trying to retrieve updated
AV and IPS packages.

C.

Service access needs to be enabled on FortiManager under System Settings > Network.

D.

FortiGate needs to have include-default-servers disabled under config system central-management.

Question 6
Multiple choice

Refer to the exhibit, which contains the partial output of a diagnose command.

Based on the output, which two statements are correct? (Choose two.)

A.

Anti-replay is enabled.

B.

DPD is disabled.

C.

Remote gateway IP is 10.200.4.1.

D.

Quick mode selectors are disabled.

Question 7
Single choice

View the exhibit, which contains the output of diagnose sys session list, and then answer the question below.

If the HA ID for the primary unit is zero (0), which statement is correct regarding the output?

A.

This session is for HA heartbeat traffic.

B.

This session is synced with the slave unit.

C.

The inspection of this session has been offloaded to the slave unit.

D.

This session cannot be synced with the slave unit.

Question 8
Single choice

Examine the following traffic log; then answer the question below.

date-20xx-02-01 time=19:52:01 devname=master device_id="xxxxxxx" log_id=0100020007 type=event
subtype=system pri critical vd=root service=kemel status=failure msg="NAT port is exhausted."

What does the log mean?

A.

There is not enough available memory in the system to create a new entry in the NAT port table.

B.

The limit for the maximum number of simultaneous sessions sharing the same NAT port has been reached.

C.

FortiGate does not have any available NAT port for a new connection.

D.

The limit for the maximum number of entries in the NAT port table has been reached.

Question 9
Single choice

Examine the following partial output from a sniffer command; then answer the question below.
