QUESTION: 10

Refer to the exhibit, which shows the output o! the BGP database.

Which two statements are correct? (Choose two.)

The advertised prefix of 10.20.30.0/24 was configured using the network command.
The first four prefixes are being advertised using a legacy route advertisement.
The advertised prefix of 10.20.30.0/24 is being advertised through the redistribution of another routing protocol.
The output shows all prefixes advertised by all neighbors as well as the local router.

Answer(s): A,D

Explanation:

For Option A:
In Fortinet BGP (and standard BGP), when a prefix is displayed with an "i" (lowercase i) in the Path column, it represents an internal prefix that originated from the local router, typically configured via the BGP "network" command. In the exhibit, the prefix 10.20.30.0/24 is listed with a Path value of i, indicating it was injected into BGP by the local router using the network statement, not via redistribution from another routing protocol. The same logic applies to i as documented: "Origin code 'i' means the route was injected via the network command."

For Option D:
The get router info bgp network output is a summary table displaying both local and received BGP routes. It lists all known routes to the BGP process, whether received from peers or originated locally. The exhibit shows all BGP prefixes known to the local router, matching the official admin guide's description of this command's output.

Explanation for B and C:

The phrase "legacy route advertisement" is not formalized in BGP documentation or Fortinet's admin guide; the output uses standard BGP mechanics.

If a route was redistributed into BGP from another routing protocol, the Path field would display a "?" (question mark) for incomplete (redistributed) origin. Here the /24 route has "i" so it is NOT a redistribution.

QUESTION: 12

Refer to the exhibit, which shows the output of get router info bgp summary.

Which two statements are true? (Choose two.)

The local ForliGate has received one prefix from BGP neighbor 100.64.1.254.
The TCP connection with BGP neighbor 100.64.2.254 was successful.
The local FortiGate has received 18 packets from a BGP neighbor.
The local FortiGate is still calculating the prefixes received from BGP neighbor 100.64.2.264

Answer(s): A,C

Explanation:

The get router info bgp summary output lists BGP neighbor status:

Prefix Reception: The "State/PfxRcd" column shows the number of prefixes received from the neighbor--neighbor 100.64.1.254 has "1", confirming option A.

Received Message Count: Under "MsgRcvd", 18 packets have been received from neighbor 100.64.1.254. This matches option C.

The second neighbor 100.64.2.254 is in "Active" state and has received/sent 0 packets, indicating that its TCP connection is NOT established, disproving option B.

There is no indication anywhere that the router is "still calculating" prefixes; "Active" just means no session is established, so option D is incorrect.

QUESTION: 13

Which exchange lakes care of DoS protection in IKEv2?

Create_CHILD_SA
IKE_Auth
IKE_Req_INIT
IKE_SA_NIT

Answer(s): C

Explanation:

The IKE_SA_INIT exchange in IKEv2 is responsible for DoS protection measures. During IKE_SA_INIT, before authentication and further exchange, the responder can use cookie challenges (per RFC 7296 and Fortinet VPN documentation). If a DoS attack is suspected (many requests from the same source), the responder replies with a cookie. Only after the initiator returns the correct cookie does the exchange proceed, protecting the responder from state exhaustion and certain forms of DoS traffic at the handshake stage.

QUESTION: 14

Refer to the exhibit, which shows a partial output of the fssod daemon real-time debug command.

What two conclusions can you draw from the output? (Choose two.)

The workstation with IP 10.124.2.90 will be polled frequently using TCP port 445 to see if the user is still logged on.
The logon event can be seen on the collector agent installed on Windows.
FSSO is using DC agent mode to detect logon events.
FSSO is using agentless polling mode to detect logon events.

Answer(s): A,D

Explanation:

https://community.fortinet.com/t5/FortiGate/Troubleshooting-Tip-How-to-troubleshoot-FSSO- agentless-polling/ta-p/214349

From the snippet we can see that FortiGate (via the fssod daemon) is directly detecting the user logon rather than relying on a separate "collector" or "DC agent." This indicates agentless polling-- FortiGate polls the DC's event logs over TCP 445 to discover logons. So: - FSSO is using agentless polling mode to detect logon events - In agentless mode, FortiGate will periodically poll the same IP (the DC) on port 445 to see if the user is still logged on

QUESTION: 15

An administrator wants to capture encrypted phase 2 traffic between two FotiGate devices using the built-in sniffer.

If the administrator knows that there Is no NAT device located between both FortiGate devices, which command should the administrator run?

diagnose sniffer packet any 'udp port 500'
diagnose sniffer packet any 'lp proto 50'
diagnose sniffer packet any 'udp port 4500'
diagnose sniffer packet any 'ah'

Answer(s): B

Explanation:

To capture encrypted IPsec phase 2 (ESP) traffic between two FortiGate devices, the correct protocol filter to use is ip proto 50. According to the Fortinet official sniffing and debugging documentation, ESP (Encapsulating Security Payload) is used for encrypted phase 2 payload transfer and always uses IP protocol number 50. Running the command diagnose sniffer packet any 'ip proto 50' captures only ESP packets, which represent the encrypted traffic--whether originating or transiting the device.

If there is no NAT device between FortiGates, ESP is not encapsulated in UDP (thus not on UDP port 4500; if NAT-T were required, packets would be UDP-encapsulated, but the scenario explicitly says

NAT is not in use). UDP port 500 is for IKE control (negotiation) traffic, and AH (Authentication Header, ip proto 51) is not used for encryption in standard IPsec phase 2 with ESP.

This matches the official CLI reference from Fortinet for VPN and traffic analysis.

QUESTION: 16

Refer to the exhibits.

An administrator Is expecting to receive advertised route 8.8.8.8/32 from FGT-A. On FGT-B, they confirm that the route is being advertised and received, however, the route is not being injected into the routing table.
What is the most likely cause of this issue?

A batter route to the 8.8.8.8/32 network exists in the routing table.
FGT-B is configured with a prefix list denying the 8.8.8.8/32 network to be injected into the routing table.
The administrator has misconfigured redistribution of routes on FGT-A.
FGT-8 is configured with a distribution list denying the 8.8.8.8/32 network to be injected into the routing table.

Answer(s): B

Explanation:

The 8.8.8.8/32 route is visible in the OSPF database on FGT-B but not installed into the routing table--the most likely explanation is that FGT-B is filtering it from being installed.
