NEW QUESTION # 26
What is the role of the FortiGate 'set srcintf' command in a firewall policy?
- A. Specifies the source interface for traffic matching
- B. Configures the source NAT interface
- C. Sets the source IP address range
- D. Defines the destination interface for traffic
Answer: A
Explanation:
The 'set srcintf' command in a FortiGate firewall policy specifies the source interface from which traffic originates, helping define the policy's scope. It does not set the destination interface (B), source IP range (C), or NAT interface (D). Exact extract: "The 'set srcintf' command in a firewall policy specifies the source interface for incoming traffic, allowing FortiGate to match packets based on their entry interface."
NEW QUESTION # 27
How does a stateful firewall control a TCP session?
- A. TCP sequence numbers and TCP flags are used to control the session
- B. TCP destination ports are used to control the session
- C. TCP ack numbers are used to control the session
- D. TCP source ports are used to control the session
Answer: A
Explanation:
A stateful firewall, like FortiGate, tracks TCP sessions by maintaining a state table that includes TCP sequence numbers and flags (e.g., SYN, ACK, FIN) to monitor the connection's lifecycle (establishment, data transfer, termination). This ensures proper session handling, detecting out-of-order packets or invalid states.
Source and destination ports identify the session but don't control its state, and ACK numbers alone are insufficient. Exact extract: "Stateful inspection tracks TCP sessions using sequence numbers and TCP flags (SYN, ACK, FIN, etc.) to ensure packets are valid and part of an established session... FortiGate maintains a state table to monitor the TCP connection states."
NEW QUESTION # 28
Which of the following protocols operates at Layer 4
- A. OSPF
- B. IPSEC
- C. ARP
- D. BGP
Answer: B
Explanation:
IPsec operates at Layer 4 (Transport Layer) in the OSI model, providing secure communication via protocols like ESP and AH, which work with TCP or UDP. BGP and OSPF are Layer 3 (Network Layer) routing protocols, and ARP operates at Layer 2 (Data Link Layer). Fortinet's FortiGate uses IPsec for VPNs at Layer
4. Exact extract: "IPsec operates at the Transport Layer (Layer 4) to secure communications, encapsulating TCP or UDP packets... BGP and OSPF function at the Network Layer, while ARP resolves IP to MAC addresses at the Data Link Layer."
NEW QUESTION # 29
Which of the below technology(ies) could reduce CPU load and memory utilization used by an IPS engine?
- A. Using regular instead of extended database, to reduce memory footprint
- B. Using IPS sensors and IPS filter to determine which traffic should be examined for which signatures, instead of examine network traffic for all signatures
- C. Using multiple engines, aligned with load balancing technologies like Turbo that uses round robin algorithms to dispatch traffic up to specific IPS engine
- D. All of the above
- E. IPS does not compare traffic to each signature individually. Instead it compiles them into a decision tree
Answer: A,B,E
Explanation:
IPS efficiency is improved by: A) Compiling signatures into a decision tree to reduce comparison overhead; B) Using IPS sensors/filters to selectively apply signatures to relevant traffic, reducing unnecessary processing; D) Using a regular database instead of an extended one to lower memory usage. Option C's
"Turbo" and round-robin load balancing is not a standard Fortinet IPS feature. Option E is incorrect as C is not valid. Exact extract: "IPS efficiency is improved by compiling signatures into decision trees to minimize CPU usage... IPS sensors and filters allow selective signature application to reduce processing... Using the regular signature database instead of extended reduces memory footprint."
NEW QUESTION # 30
In Active FTP who sends the PORT command?
- A. The FTP Server
- B. The FTP Client
- C. There is no PORT command in Active FTP
- D. Both
Answer: B
Explanation:
In Active FTP, the client sends the PORT command to the server, specifying an ephemeral port for the server to initiate the data connection back to the client. This distinguishes Active FTP from Passive FTP, where the server provides the port. The server does not send PORT, and the command is a key part of Active FTP. Exact extract: "In Active FTP, the client sends a PORT command to the server, specifying the IP address and port number for the data connection... The server then initiates the data connection to the client's specified port."
NEW QUESTION # 31
How many layers does the OSI Model contain?
- A. 0
- B. 1
- C. 2
- D. 3
Answer: B
Explanation:
The OSI (Open Systems Interconnection) model consists of seven layers: Physical, Data Link, Network, Transport, Session, Presentation, and Application. This framework is used in Fortinet documentation to explain protocol operations. Options A, C, and D are incorrect as they do not match the standard OSI model.
Exact extract: "The OSI model defines seven layers for network communication: 1. Physical, 2. Data Link, 3.
Network, 4. Transport, 5. Session, 6. Presentation, 7. Application."
NEW QUESTION # 32
A firewall receives an out-of-order packet in a TCP session after the FIN/ACK and the packet is dropped as expected. What parameter can be changed to prevent such drops?
- A. TCP close-wait timer
- B. Enable TCP option
- C. TCP time-wait timer
- D. TCPMSS
Answer: C
Explanation:
Out-of-order packets after FIN/ACK indicate a packet arriving in the TIME_WAIT state, where the session is closing. The TCP time-wait timer controls how long the firewall keeps the session in the TIME_WAIT state to handle late packets. Increasing this timer allows the firewall to accept such packets instead of dropping them. Close-wait timer relates to a different state, TCPMSS affects packet size, and "Enable TCP option" is not a standard parameter. Exact extract: "The TCP time-wait timer determines how long a session remains in the TIME_WAIT state to handle out-of-order or retransmitted packets after FIN/ACK... Adjusting this timer can prevent drops of late-arriving packets."
NEW QUESTION # 33
Firewall is performing stateful inspection for TCP traffic between Client 10.0.0.21 and Server 172.16.1.200.
- A. Traffic should be allowed
- B. Traffic is Asymmetric and not allowed by the Firewall
- C. The ACK was not supposed to be sent to client 10.0.0.21
- D. Three way handshake was not completed
Answer: D
Explanation:
Stateful inspection requires a complete TCP three-way handshake (SYN, SYN-ACK, ACK) to establish a session in the firewall's state table. If the handshake is incomplete (e.g., missing ACK), the session is not established, and traffic is dropped. The question implies a stateful firewall scenario where traffic is blocked, likely due to an incomplete handshake. Asymmetric traffic (B) or incorrect ACK (A) are not indicated without further context, and C is incorrect if the handshake fails. Exact extract: "Stateful inspection ensures that a TCP three-way handshake is completed before allowing traffic... If the handshake is not completed, FortiGate drops the packets as invalid."
NEW QUESTION # 34
What happens when a router receives a packet for forwarding with a TTL value of 1?
- A. The TTL is decreased to 0, the packet is dropped and an ICMP message is sent to the transmitting IP
- B. The packet is only forwarded through the router to a locally attached network
- C. It increments it and passes it on to the next router
- D. It decreases the value to 0 and then forwards it
Answer: A
Explanation:
When a router, such as a FortiGate, receives a packet with a TTL (Time to Live) of 1, it decrements the TTL to 0, drops the packet, and sends an ICMP Time Exceeded message to the source IP. This prevents infinite loops in routing. Option A is incorrect as TTL is decremented, not incremented; B and D are incorrect as the packet is not forwarded when TTL reaches 0. Exact extract: "When a packet's TTL reaches 1, the router decrements it to 0, drops the packet, and sends an ICMP Time Exceeded message to the source IP address to prevent routing loops."
NEW QUESTION # 35
Which parts of the IKE protocol below are responsible for authenticating the User (username/password) of a dialup IPsec tunnel? (Check all correct answers)
- A. IKEv2 SA_INIT
- B. IKEv1 phase1
- C. IKEv2 EAP
- D. IKEv1 phase2
- E. IKEv1 Xauth
Answer: C,E
Explanation:
For user authentication in dialup IPsec, IKEv1 uses XAuth (Extended Authentication) after Phase 1 for username/password. IKEv2 uses EAP (Extensible Authentication Protocol) for similar user auth. Phase 1 and SA_INIT are for peer auth, Phase 2 for child SA negotiation. Exact extract: XAuth increases security by requiring remote dialup client users to authenticate in a separate exchange at the end of phase 1. IPsec IKEv2 VPNs now support certificate authentication and EAP authentication at the same time from a dialup FortiClient. With the eap-cert-auth setting ... IPsec IKEv2 VPNs now support certificate authentication and EAP authentication at the same time from a dialup FortiClient. IPsec IKEv1 uses XAUTH for user authentication, and IPsec IKEv2 uses EAP for user authentication. Only EAP-TTLS is interoperable with LDAP. For LDAP based user ... In your scenario, the user cannot authenticate by providing both a PSK and their credentials (using one of multiple EAP methods).
NEW QUESTION # 36
Which FortiGate log type records denied traffic events?
- A. Event Log
- B. System Log
- C. Security Log
- D. Traffic Log
Answer: D
Explanation:
Traffic Logs in FortiGate record all traffic events, including denied packets, with details like source, destination, and policy ID. Security Logs (B) cover UTM events, Event Logs (C) system events, and System Logs (D) hardware or system status, not specifically denied traffic. Exact extract: "Traffic Logs record all packet activity, including allowed and denied traffic, with details such as source/destination IPs, ports, and the firewall policy applied."
NEW QUESTION # 37
Link aggregation allows network devices to________
- A. None of the above
- B. Restrict the bandwidth
- C. Increase bandwidth by binding physical interfaces into a single channel
- D. Increase bandwidth of an interface
Answer: C
Explanation:
Link aggregation, also known as IEEE 802.3ad or 802.1ax, enables the binding of multiple physical interfaces to form a single logical interface, which increases the overall bandwidth and provides redundancy. This is achieved by combining the bandwidth of the individual links into one aggregated link. For example, if two
1Gbps interfaces are aggregated, the logical link can provide up to 2Gbps bandwidth. This configuration is commonly used in FortiGate devices to enhance network performance without replacing hardware. The option B correctly describes this by stating "Increase bandwidth by binding physical interfaces into a single channel," which aligns with the official description. Incorrect options include A, which is vague and does not specify the method of binding multiple interfaces; C, which is the opposite of the purpose; and D, which is invalid.
Exact extract: Link aggregation (IEEE 802.3ad/802.1ax) enables you to bind two or more physical interfaces together to form an aggregated (combined) link. This new link ... Link aggregation combines multiple physical interfaces into a single logical interface, increasing bandwidth and link redundancy. Traffic is distributed evenly.

NEW QUESTION # 39
What are source and destination MAC addresses of an ARP request?
- A. The source MAC is that of the sending device and the destination MAC is a broadcast address
- B. The source MAC is that of the sending device and the destination of the targeted device
- C. The source MAC is that of the forwarding switch and destination of the targeted device
- D. The source MAC is that of the sending device and the destination is a multicast address
Answer: A
Explanation:
An ARP (Address Resolution Protocol) request is broadcast to resolve an IP address to a MAC address. The source MAC is the sender's MAC address, and the destination MAC is the broadcast address (FF:FF:FF:FF:
FF:FF) to reach all devices on the local network. Fortinet devices handle ARP for Layer 2 communication.
Options B, C, and D are incorrect as switches don't originate ARP requests, the target's MAC is unknown, and ARP uses broadcast, not multicast. Exact extract: "In an ARP request, the source MAC address is that of the sending device, and the destination MAC address is the broadcast address (FF:FF:FF:FF:FF:FF), sent to all devices in the local network segment."
NEW QUESTION # 40

- A. Cloud provider provides both 32-bit and 64-bit virtual machines
- B. The cloud provider uses AMD, Intel and possibly also other CPU vendors
- C. Some of the customer's systems are virtualized in the public cloud and some are in the local datacenter
- D. One customer uses VMs with multiple different operating systems in the same cloud account
Answer: C
Explanation:
A hybrid cloud combines on-premises infrastructure (local datacenter) with public cloud resources, allowing workloads to operate across both environments for flexibility and scalability. Fortinet solutions like FortiGate- VM support hybrid cloud deployments. Option A refers to hardware diversity, C to OS variety, and D to architecture types, none of which define hybrid cloud. Exact extract: "Hybrid cloud is the combination of public cloud services with an on-premises private cloud or datacenter... This allows customers to run some systems in the public cloud and others in their local datacenter, managed seamlessly."

- A. To monitor system performance metrics
- B. To show the packet flow through firewall policies
- C. To troubleshoot routing table issues
- D. To display real-time packet captures
Answer: B
Explanation:
The 'diagnose debug flow' command in FortiGate is used to troubleshoot how packets are processed through firewall policies, showing details like policy matching, NAT, and session handling. It helps identify why packets are allowed or dropped. Option A refers to packet sniffing, B to routing diagnostics, and D to performance monitoring, none of which are the primary function. Exact extract: "The diagnose debug flow command displays the packet flow through FortiGate, including policy matching, NAT, and session details, useful for troubleshooting traffic issues."
NEW QUESTION # 42
Which FortiGate feature allows for policy-based routing?
- A. SD-WAN Rules
- B. Static Routes
- C. Dynamic Routes
- D. Policy Routes
Answer: D
Explanation:
Policy Routes in FortiGate allow routing decisions based on criteria like source, destination, or service, overriding the default routing table. SD-WAN Rules (A) are for WAN optimization, Static Routes (C) are fixed, and Dynamic Routes (D) are protocol-based, not policy-based. Exact extract: "Policy Routes allow FortiGate to make routing decisions based on user-defined criteria, such as source/destination IPs or services, overriding standard routing."
NEW QUESTION # 43
Which FortiGate feature mitigates DDoS attacks by limiting the rate of incoming connections?
- A. IPS Signature
- B. DoS Policy
- C. Web Filtering
- D. Application Control
Answer: B
Explanation:
FortiGate's DoS (Denial of Service) Policy limits the rate of incoming connections or packets to mitigate DDoS attacks, such as SYN floods, by setting thresholds for specific traffic types. IPS Signatures (B) detect specific attack patterns, Application Control (C) manages app usage, and Web Filtering (D) blocks URLs, none of which focus on rate limiting. Exact extract: "DoS policies protect against DDoS attacks by limiting the rate of incoming connections or packets, such as SYN floods, based on configured thresholds."
NEW QUESTION # 44
What does the below route indicate?
- A. The device does not know the destination
- B. The destination network is locally connected on that interface
- C. The destination network can be reached via any gates
- D. It is a dummy route in the routing table
Answer: B
Explanation:
A route with a directly connected interface (no gateway) indicates the destination network is locally attached to that interface on the FortiGate. This is common for networks directly connected to the device's interfaces.
Option A is vague, B is incorrect as it's not a dummy route, and D suggests an unknown route, which isn't the case. Exact extract: "A directly connected route indicates that the destination network is locally attached to the interface specified in the routing table... No gateway is required for such routes as the FortiGate is directly connected to the network."
NEW QUESTION # 45
Which term refers to the OSPF router that connects area 0 to a nonbackbone area?
- A. autonomous system boundary router
- B. area border router
- C. area boundary router
- D. backbone router
Answer: B
Explanation:
The standard term in OSPF for a router connecting the backbone area (Area 0) to a non-backbone area is "area border router" (ABR). It maintains separate LSDBs for each area and performs summarization. "Area boundary router" is similar but not the standard term; ASBR connects to external AS; backbone router is in Area 0. Exact extract: Go to Network > OSPF. Set Router ID to 10.11.101.1. In the Areas table, click Create New and set the following: Area ID. 0.0. Click OK. In the Networks ... A router connected to more than one area is an area border router (ABR). An autonomous system boundary router (ASBR) is located between an OSPF autonomous ... This article describes the basic steps to configure FortiGates in an OSPF scenario where the FortiGates will be ABR and ASBR OSPF routers across 3 areas. OSPF areas are groupings of OSPF routers or logical parts of a network. An area's routing information can be sent as a summary to other areas. This article describes that routes learned from the other OSPF areas will be removed on the ABR router when it has multiple areas and has no backbone ...
NEW QUESTION # 46
Which FortiGate feature allows for dynamic routing protocol updates to be propagated through an IPsec VPN tunnel?
- A. Auto Discovery VPN (ADVPN)
- B. Dynamic Routing Gateway
- C. Virtual Routing and Forwarding (VRF)
- D. Route-based VPN
Answer: A
Explanation:
Auto Discovery VPN (ADVPN) in FortiGate enables dynamic routing protocols (e.g., OSPF, BGP) to propagate updates through IPsec VPN tunnels by automatically creating shortcut paths between spokes. This simplifies configuration and enhances scalability in hub-and-spoke topologies. Route-based VPN (D) supports routing but not dynamic discovery, VRF (C) is for segmentation, and Dynamic Routing Gateway (B) is not a standard Fortinet feature. Exact extract: "ADVPN allows dynamic routing protocols to be used over IPsec VPN tunnels, enabling spokes to discover and communicate directly via shortcuts, improving efficiency in hub-and-spoke setups."
