Question # 2

Refer to the exhibits.

A FortiGate cluster (CL-1) protects a data center hosting multiple web applications. A pair of FortiADC devices are already configured for SSL decryption (FAD-1), and re-encryption (FAD-2). CL-1 must accept unencrypted traffic from FAD-1, perform application detection on the plain-text traffic, and forward the inspected traffic to FAD-2.

The SSL-Offload-App-Detect application list and SSL-Offload protocol options profile are applied to the firewall policy handling the web application traffic on CL-1.

Given this scenario, which two configuration tasks must the administrator perform on CL-1? (Choose two.)

A)

A.

You can use src-ip or dst-ip-dport on dp-load-distribution-method to make SSL VPN load balancing work as expected.

B.

If an FPM goes down, SSL VPN IP pool IP addresses will be re-allocated to the remaining FPMs.

C.

To have better traffic distribution you should use IP pools that increment in multiples of 12.

D.

Enabling SSL VPN load balancing will clear the session table.

Question # 6

Refer to the exhibit that shows VPN debugging output.

The VPN tunnel between headquarters and the branch office is not being established.

What is causing the problem?

Question # 8

Refer to the exhibit.

You are managing a FortiSwitch 3032E that is managed by FortiLink on a FortiGate 3960E. The 3032E is heavily utilized and there is only one port free.

The requirement is to add an additional three FortiSwitch 448E devices with 10Gbps SFP+ connectivity directly to the 3032E. The plan is to use split port (phy-mode) with QSFP28 mode to connect the new 448E switches.

In this scenario, which statement about the switch deployment is correct?

A.

Additional ports on Switch 1 can be split for a maximum of 128 interfaces.

B.

C.

After enabling split ports and rebooting Switch 1, the new ports can be configured from the FortiGate.

D.

Switches 2-4 will connect successfully with Switch 1 split port in QSFP28 mode.

Question # 9

A remote IT Team is in the process of deploying a FortiGate in their lab.
