NEW QUESTION # 12
Refer to the exhibit, which contains partial output from an IKE real-time debug.


The administrator does not have access to the remote gateway.
Based on the debug output, which configuration change can the administrator make to the local gateway to resolve the phase 1 negotiation error?

• A. In the phase 1 network configuration, set the IKE version to 2.
• B. In the phase 1 proposal configuration, add AESCBC-SHA2 to the list of encryption algorithms.
• C. In the phase 1 proposal configuration, add AES128-SHA128 to the list of encryption algorithms.
• D. In the phase 1 proposal configuration, add AES256-SHA256 to the list of encryption algorithms.

Answer: D

NEW QUESTION # 13
What does the command set forward-domain <domain_ID> in a transparent VDOM interface do?

• A. It isolates traffic within a specific VLAN by assigning a broadcast domain to an interface based on the VLAN ID.
• B. It restricts the interface to managing traffic only from the specified VLAN, effectively segregating network traffic.
• C. It configures the interface to prioritize traffic based on the domain ID, enhancing quality of service for specified VLANs.
• D. It assigns a unique domain ID to the interface, allowing it to operate across multiple VLANs within the same VDOM.

Answer: A

Explanation:
In atransparent mode Virtual Domain (VDOM)configuration, FortiGate operates as aLayer 2 bridgerather than performing Layer 3 routing. Theset forward-domain <domain_ID>command is used to control how traffic is forwarded between interfaces within the sametransparent VDOM.
Aforward-domainacts as abroadcast domain, meaning only interfaces with thesame forward-domain ID can exchange traffic. This setting is commonly used toseparate different VLANs or network segments within the transparent VDOM while still allowing FortiGate to apply security policies.

NEW QUESTION # 14
Refer to the exhibits.



The configuration of a user's Windows PC, which has a default MTU of 1500 bytes, along with FortiGate interfaces set to an MTU of 1000 bytes, and the results of PC1 pinging server
172.16.0.254 are shown.
Why is the user in Windows PC1 unable to ping server 172.16.0.254 and is seeing the message:
Packet needs to be fragmented but DF set?

• A. FortiGate honors the do not fragment bit and the packets are dropped. The user has to adjust the ping MTU to 972 to succeed.
• B. Fragmented packets must be encrypted. To connect any application successfully, the user must install the Fortinet_CA certificate in the Microsoft Management Console.
• C. Option ip.flags.mf must be set to enable on FortiGate. The user has to adjust the ping MTU to
  1000 to succeed.
• D. The user must trigger different traffic because path MTU discovery techniques do not recognize ICMP payloads.

Answer: A

Explanation:
The issue occurs because FortiGate enforces the "do not fragment" (DF) bit in the packet, and the packet size exceeds the MTU of the network path. When the Windows PC1 (with an MTU of
1500 bytes) attempts to send a 1400-byte packet, the FortiGate interface (with an MTU of 1000 bytes) needs to fragment it. However, since the DF bit is set, FortiGate drops the packet instead of fragmenting it.
To resolve this, the user should adjust the ping packet size to fit within the path MTU. In this case, reducing the packet size to 972 bytes (1000 bytes MTU minus 28 bytes for the IP and ICMP headers) should allow successful transmission.

NEW QUESTION # 15
Four FortiGate devices configured for OSPF connected to the same broadcast domain. The first unit is elected as the designated router.
The second unit is elected as the backup designated router.
Under normal operation, how many OSPF full adjacencies are formed to each of the other two units?

• A. 0
• B. 1
• C. 2
• D. 3

Answer: B

NEW QUESTION # 16
Refer to the exhibits. The exhibits show a network topology, a firewall policy, and an SSL/SSH inspection profile configuration.



Why is FortiGate unable to detect HTTPS attacks on firewall policy ID 3 targeting the Linux server?

• A. The administrator must enable SSL inspection of the SSL server and upload the certificate of the Linux server website to the SSL/SSH inspection profile.
• B. The administrator must enable cipher suites in the SSL/SSH inspection profile to decrypt the message.
• C. The administrator must set the policy to inspection mode to analyze the HTTPS packets as expected.
• D. The administrator must enable HTTPS in the protocol port mapping of the deep- inspection SSL/SSH inspection profile.

Answer: A

Explanation:
The FortiGateSSL/SSH inspection profileis configured forFull SSL Inspection, which is necessary to analyze encrypted HTTPS traffic. However, the firewallpolicy is protecting an SSL server (the Linux server hosting the website), and currently, the SSL/SSH profileonly applies to client-side SSL inspection.
To detect HTTPS-based attacks targeting the Linux server:
#FortiGate must act as an SSL intermediaryto inspect encrypted traffic destined for the web server.
# The administratormust upload the SSL certificate of the Linux web serverto FortiGate so that theserver- side SSL inspectioncan decrypt incoming HTTPS traffic before analyzing it.

NEW QUESTION # 22
An administrator applied a block-all IPS profile for client and server targets to secure the server, but the database team reported the application stopped working immediately after.
How can an administrator apply IPS in a way that ensures it does not disrupt existing applications in the network?

• A. Set the IPS profile signature action to default to discard all possible false positives.
• B. Use an IPS profile with all signatures in monitor mode and verify patterns before blocking.
• C. Select flow mode in the IPS profile to accurately analyze application patterns.
• D. Limit the IPS profile to server targets only to avoid blocking connections from the server to clients.

Answer: B

Explanation:
Applying anaggressive IPS profilewithout prior testing candisrupt legitimate applicationsby incorrectly identifying normal traffic as malicious. To prevent disruptions while still monitoring for threats:
#Enable IPS in "Monitor Mode" first:
# This allows FortiGate tolog and analyzepotential threatswithout actively blockingtraffic.
# Administrators can review logs and fine-tune IPS signatures to minimize false positives before switching to blocking mode.
#Verify and adjust signature patterns:
# Some signatures might trigger unnecessary blocks for legitimate application traffic.
# By analyzing logs, administrators candisable or modifyspecific rules causing false positives.

Answer: A,D

NEW QUESTION # 26
Refer to the exhibit, which shows an ADVPN network.

An administrator must configure an ADVPN using IBGP and EBGP to connect overlay network 1 with 2.
What two options must the administrator configure in BGP? (Choose two.)

• A. set ebgp-enforce-multrhop enable
• B. set ibgp-enforce-multihop advpn
• C. set attribute-unchanged next-hop
• D. set next-hop-self enable

Answer: A,D

Explanation:
In this ADVPN (Auto-Discovery VPN) network, there are two hubs (Hub A and Hub B) connected via EBGP, while IBGP is used within each overlay. To ensure proper BGP routing between the overlays, the administrator must configure specific BGP options..
set ebgp-enforce-multihop enable
By default, EBGP requires directly connected neighbors. Since Hub A and Hub B are not directly connected but reach each other over an IPsec tunnel, multihop must be enabled for EBGP sessions to work.
set next-hop-self enable
In IBGP, the next-hop attribute does not change by default. When an IBGP route is advertised from a spoke to another hub or spoke, the next-hop needs to be updated to ensure proper reachability. Enabling next-hop-self forces the BGP speaker to advertise itself as the next-hop, ensuring that all spokes properly reach routes across the overlays.
