NEW QUESTION # 13
Refer to the exhibit. An IPsec VPN tunnel is dropping, as shown by the debug output. Analyzing the debug output, what could be causing the tunnel to go down?

  • A. Phase 2 drops but Phase 1 is up.
  • B. The tunnel drops after the timer expires.
  • C. The tunnel drops during rekey negotiation.
  • D. Dead Peer Detection is not receiving its acknowledge packet.

Answer: D

Explanation:
The continual "notify msg received: R-U-THERE" without any corresponding DPD response causes the FortiGate to delete the IPsec SA when its Dead Peer Detection timer expires, bringing the tunnel down.


NEW QUESTION # 14
Refer to the exhibit, which shows the omitted output of a session table entry.

Which two statements are true? (Choose two.)

  • A. The session has been offloaded.
  • B. NP7 is handling offloading of this session.
  • C. The traffic has been tagged for VLAN 0000.
  • D. The traffic matches Policy ID 1.

Answer: A,D

Explanation:
The session has been offloaded.
The offload=8/8, ips_offload=1/1, and in_npu=1/1 out_npu=1/1flags show both the forwarding and IPS functions are being handled in hardware.
The traffic matches Policy ID 1.
The policy_id=1field indicates this session was created by firewall policy 1.


NEW QUESTION # 15
Refer to the exhibit. The exhibit shows the output from using the command diagnose debug application samld -1 to diagnose a SAML connection.

Based on this output, what can you conclude?

  • A. The authentication request is for an SSL VPN connection.
  • B. The IdP IP address is 10.1.10.254.
  • C. Active Directory is used for authentication.
  • D. The IdP IP address is 10.1.10.2.

Answer: D

Explanation:
The SAML AuthnRequest's Destination and RemoteProviderID URLs both point to https://10.1.10.2, indicating the IdP's IP address is 10.1.10.2.


NEW QUESTION # 16
Refer to the exhibits, which show the configuration on FortiGate and partial internet session information from a user on the internal network.


An administrator would like to lest session failover between the two service provider connections.
Which two changes must the administrator make to force this existing session to immediately start using the other interface? (Choose two.)

  • A. Change the priority of the port2static route to 5.
  • B. Configure unset snap-route-changeto return it to the default setting.
  • C. Configure set snat-route-change enable.
  • D. Change the priority of the port1static route to 11.

Answer: C,D

Explanation:
set snat-route-change enable - With it disabled, existing SNAT sessions keep using the original egress interface even if routing changes. Enabling it lets the FortiGate remap the live session to the new route immediately.
Change port1 route priority to 11 - Raising port1's priority makes port2's route (priority 10) become the best path, so the session will switch to port2 once SNAT route change is allowed.


NEW QUESTION # 17
Refer to the exhibits.

An administrator is attempting to advertise the network configured on port3. However, FGT-A is not receiving the prefix.
Which two actions can the administrator take to fix this problem? (Choose two.)

  • A. Modify the prefix using the network command from 172.16.0.0/16 to 172.16.54.0/24.
  • B. Use the set network-import-check disable command.
  • C. Manually add the BGP route on FGT-A.
  • D. Restart BGP using a soft reset to force both peers to exchange their complete BGP routing tables.

Answer: A,B


NEW QUESTION # 18
In the SAML negotiation process, which section does the Identity Provider (IdP) provide the SAML attributes utilized in the authentication process to the Service Provider (SP)?

  • A. Assertion dump
  • B. SP Login dump
  • C. Authentication Request
  • D. Authentication Response

Answer: A

Explanation:
The IdP supplies all of the user's SAML attributes inside the <Assertion> section of its SAML response - so you'll see them in the Assertion dump portion.


NEW QUESTION # 19
Refer to the exhibit, which shows a partial output of the fssod daemon real-time debug command.

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

  • A. The logon event can be seen on the collector agent installed on Windows.

  • D. There are 98908 kB o! memory that will never be used.

Answer: A,D


NEW QUESTION # 24
Refer to the exhibit, which shows the partial output of a real-time OSPF debug.

Why are the two FortiGate devices unable to form an adjacency?

  • A. The two FortiGate devices attempting adjacency are in area 0.0.0.0.
  • B. The passwords on the FortiGate devices do not match.
  • C. One FortiGate device is configured to require authentication, while the other is not.
  • D. The Hello packet is being sent from an OSPF router with ID 0.0.0.112.

Answer: C

Explanation:
One FortiGate is sending Hellos with authentication (non zero AuthType) while the other is set to AuthType 0, triggering an "Authentication type mismatch" and preventing adjacency.


NEW QUESTION # 25
Which two statements are true regarding heartbeat messages sent from an FSSO collector agent to FortiGate? (Choose two.)

  • A. The heartbeat messages can be seen in the collector agent logs.
  • B. The heartbeat messages must be manually enabled on FortiGate.
  • C. The heartbeat messages can be seen using the command diagnose debug authd fsso list.
  • D. The heartbeat messages can be seen on FortiGate using the real-lime FSSO debug.

Answer: A,D


NEW QUESTION # 26
Refer to the exhibit, which shows the partial output of a diagnose command.

Which two conclusions can you draw from the output shown in the exhibit? (Choose two.)

  • A. This is a pinhole session to allow traffic for a TCP protocol that dynamically assigns TCP ports.
  • B. Clearing the master session has no impact on the expectation session.
  • C. The session is checked against firewall policy ID 25.
  • D. FortiGate will drop the expected traffic if it does not arrive within 23 seconds.

Answer: A,D

Explanation:
The "expire=23" value shows this expectation entry will be removed - and any matching packets subsequently dropped - if the expected traffic doesn't arrive within 23 seconds.
Because it's a TCP-based expectation entry (proto=6) set up to allow dynamically assigned ports, it's acting as a pinhole session for a protocol that opens ephemeral TCP ports.


NEW QUESTION # 27
Refer to the exhibit, which contains a screenshot of some phase 1 settings.

The VPN is up. To monitor traffic flow, the administrator enters the following CLI commands on an SSH session on FortiGate:
diagnose sniffer packet any 'udp and port 500' 4
diagnose debug enable
However, the sniffer does not show any output. Why?

  • A. Change the filter to sniff protocol TCP.
  • B. It must sniff IP address 10.0.10.1.
  • C. NAT Traversal is enabled.
  • D. Change the filter to sniff traffic on port1.

Answer: C

Explanation:
With NAT-T on, IKE traffic is encapsulated in UDP port 4500 (not port 500) once the tunnel is up, so your udp port 500filter never matches any packets.


NEW QUESTION # 28
Refer to the exhibit. Antivirus is unable to detect an infected file downloaded through HTTPS. Part of the configuration used for antivirus inspection is shown in the exhibit.
Which configuration changes can be performed to inspect HTTPS?

  • A. Increase the maximum number of subdirectories and nested archives.
  • B. Set a different antivirus database.
  • C. Enable SSL deep inspection.
  • D. Disable the emulatorsetting.

Answer: C

Explanation:
You must switch from mere certificate inspection to full SSL deep inspection on the HTTPS profile so that the FortiGate can decrypt the traffic and pass it through the AV engine. In practice this means editing the SSL/SSH profile and setting the HTTPS inspection mode to deep-inspection (and ensuring your CA cert is installed on the clients).


NEW QUESTION # 29
Exhibit.

Refer to the exhibit, which shows the output of a session. Which two statements are true? (Choose Iwo.)

  • A. The session was initiated from an authenticated user.
  • B. The session is being inspected using flow inspection.

  • A. Phase 2 drops but Phase 1 is up.
  • B. The tunnel drops after the timer expires.
  • C. The tunnel drops during rekey negotiation.
  • D. Dead Peer Detection is not receiving its acknowledge packet.

Answer: D


NEW QUESTION # 31
