VLAN Mode is a more efficient way to connect a FortiExtender to a FortiGate than CAPWAP Mode. This is because VLAN Mode does not require the FortiExtender to send additional control traffic to the FortiGate.

The other options are not correct.

A . Add a switch between the FortiGate and FEX. This will add overhead to the network, as the switch will need to process the traffic.

B . Enable CAPWAP connectivity between the FortiGate and the FortiExtender. This will increase the overhead on the FortiGate, as it will need to process additional control traffic.

D . Add a VLAN under the FEX-WAN interface on the FortiGate. This will not affect the overhead on the FortiGate.

The OSPF configuration shown in the exhibit is using the default priority value of 1 for the interface port1. This means that FGT_3 will participate in the DR/BDR election process with the other OSPF routers on the same LAN segment. However, this is not desirable because FGT_3 is a new device that needs to be added to the OSPF network without affecting the existing DR/BDR election. Therefore, to make sure FGT_3 will establish OSPF neighbors without affecting the DR/BDR election, the priority value of the interface port1 should be changed to 0. This will prevent FGT_3 from becoming a DR or BDR and allow it to form OSPF adjacencies with the current DR and BDR. Option B shows the correct configuration that changes the priority value to 0. Option A is incorrect because it does not change the priority value. Option C is incorrect because it changes the network type to point-to-point, which is not suitable for a LAN segment with multiple OSPF routers. Option D is incorrect because it changes the area ID to 0.0.0.1, which does not match the area ID of the other OSPF routers on the same LAN segment.

The firewall policy in the exhibit allows all traffic from the internal network to the cloud. To enforce authentication on this traffic, the administrator needs to add the auth-on-demand option to the policy. This option will force all users to authenticate before they are allowed to access the cloud.

The following is the correct configuration:

config firewall policy

edit 1

set srcintf 'internal'

set dstintf 'wan1'

set srcaddr 'all'

set dstaddr 'all'

set service 'all'

set action accept

set auth-on-demand enable

The CLI script in option A will send the log message to the webhook server. The webhook server can then be configured to take any desired action, such as storing the log message in a database or sending an email notification.

The other options are incorrect. Option B will not send the log message to the webhook server because it does not contain the curl command. Option C will send the log message to the webhook server, but it will also include the FortiGate's IP address and MAC address. This information is not necessary, and it could be used by an attacker to identify the FortiGate. Option D will not send the log message to the webhook server because it does not contain the webhook action.

To control multicast traffic passing through a FortiGate configured in transparent mode, you can use multicast policies. Multicast policies allow you to filter multicast traffic based on source and destination addresses, protocols, and interfaces. You can also apply security profiles to scan multicast traffic for threats and violations.

Graceful-restart is a feature that allows BGP neighbors to maintain their routing information during a BGP restart or failover event, without disrupting traffic forwarding or causing route flaps. Graceful-restart works by allowing a BGP speaker (the restarting router) to notify its neighbors (the helper routers) that it is about to restart or failover, and request them to preserve their routing information and forwarding state for a certain period of time (the restart time). The helper routers then mark the routes learned from the restarting router as stale, but keep them in their routing table and continue forwarding traffic based on them until they receive an end-of-RIB marker from the restarting router or until the restart time expires. This way, graceful-restart can minimize traffic disruption and routing instability during a BGP restart or failover event.
