Refer to the exhibit.

The exhibit shows the forensics analysis of an event detected by the FortiEDR core In this scenario, which statement is correct regarding the threat?

A. This is a ransomware attack and has been stopped by FortiEDR
B. This is an exfiltration attack and has not been stopped by FortiEDR
C. This is an exfiltration attack and has been stopped by FortiEDR.
D. This is a ransomware attack and has not been stopped by FortiEDR.

正解：A

解説：
The exhibit shows the forensics analysis of an event detected by the FortiEDR core. The event graph indicates that a process named svchost.exe was launched by a malicious file named 1.exe, which was downloaded from a suspicious URL. The process then attempted to encrypt files in various folders, such as Documents, Pictures, and Desktop, which are typical targets of ransomware attacks. However, FortiEDR was able to stop the process and prevent any file encryption by applying its real-time post-execution prevention feature. Therefore, this is a ransomware attack and has been stopped by FortiEDR.

質問 # 35
You must configure an environment with dual-homed servers connected to a pair of FortiSwitch units using an MCLAG.
Multicast traffic is expected in this environment, and you should ensure unnecessary traffic is pruned from links that do not have a multicast listener.
In which two ways must you configure the igmps-f lood-traffic and igmps-flood-report settings? (Choose two.)

A. enable on ICL trunks
B. disable on ICL trunks
C. disable on the ISL and FortiLink trunks
D. enable on the ISL and FortiLink trunks

正解：B、D

解説：
To ensure that unnecessary multicast traffic is pruned from links that do not have a multicast listener, you must disable IGMP flood traffic on the ICL trunks and enable IGMP flood reports on the ISL and FortiLink trunks.
Disabling IGMP flood traffic will prevent the FortiSwitch units from flooding multicast traffic to all ports on the ICL trunks. This will help to reduce unnecessary multicast traffic on the network.
Enabling IGMP flood reports will allow the FortiSwitch units to learn which ports are interested in receiving multicast traffic. This will help the FortiSwitch units to prune multicast traffic from links that do not have a multicast listener.

You must configure an environment with dual-homed servers connected to a pair of FortiSwitch units using an MCLAG.
Multicast traffic is expected in this environment, and you should ensure unnecessary traffic is pruned from links that do not have a multicast listener.
In which two ways must you configure the igmps-f lood-traffic and igmps-flood-report settings? (Choose two.)

A. disable on the ISL and FortiLink trunks
B. enable on ICL trunks
C. disable on ICL trunks
D. enable on the ISL and FortiLink trunks

正解：A、C

解説：
A is correct because disabling igmps-flood-traffic and igmps-flood-report on ICL trunks prevents unnecessary multicast traffic from being flooded across the MCLAG cluster members. C is correct because disabling igmps-flood-traffic and igmps-flood-report on the ISL and FortiLink trunks prevents unnecessary multicast traffic from being flooded to other switches or FortiGates that do not have multicast listeners. Reference: https://docs.fortinet.com/document/fortiswitches/6.4.0/administration-guide/381057/multicast-forwarding https://docs.fortinet.com/document/fortiswitches/6.4.0/administration-guide/381057/multicast-forwarding/381058/configuring-multicast-forwarding

質問 # 37
Refer to the exhibit, which shows a Branch1 configuration and routing table.

In the SD-WAN implicit rule, you do not want the traffic load balance for the overlay interface when all members are available.
In this scenario, which configuration change will meet this requirement?

A. Configure the cost in each overlay member to 10.
B. Create a new static route with the internet sdwan-zone only
C. Change the load-balance-mode to source-ip-based.
D. Configure the priority in each overlay member to 10.

正解：D

解説：
The default load balancing mode for the SD-WAN implicit rule is source IP based. This means that traffic will be load balanced evenly between the overlay members, regardless of the member's priority.
To prevent traffic from being load balanced, you can configure the priority of each overlay member to 10. This will make the member ineligible for load balancing.
The other options are not correct. Changing the load balancing mode to source-IP based will still result in traffic being load balanced. Creating a new static route with the internet sdwan-zone only will not affect the load balancing of the overlay interface. Configuring the cost in each overlay member to 10 will also not affect the load balancing, as the cost is only used when the implicit rule cannot find a match for the destination IP address.

質問 # 38
Refer to the exhibit showing FortiGate configurations

FortiManager VM high availability (HA) is not functioning as expected after being added to an existing deployment.
The administrator finds that VRRP HA mode is selected, but primary and secondary roles are greyed out in the GUI The managed devices never show online when FMG-B becomes primary, but they will show online whenever the FMG-A becomes primary.
What change will correct HA functionality in this scenario?

A. Make the monitored IP to match on both FortiManager devices.
B. Change the FortiManager IP address on the managed FortiGate to 10.3.106.65.
C. Unset the primary and secondary roles in the FortiManager CLI configuration so VRRP will decide who is primary.
D. Change the priority of FMG-A to be numerically lower for higher preference

正解：A

解説：
B is correct because the monitored IP must match on both FortiManager devices for HA to function properly. This is explained in the FortiManager Administration Guide under High Availability > Configuring HA options > Configuring HA options using the GUI. Reference: https://docs.fortinet.com/document/fortimanager/7.4.0/administration-guide/568591/high-availability https://docs.fortinet.com/document/fortimanager/7.4.0/administration-guide/568591/high-availability/568592/configuring-ha-options

質問 # 39
A customer's cybersecurity department needs to implement security for the traffic between two VPCs in AWS, but these belong to different departments within the company. The company uses a single region for all their VPCs.
Which two actions will achieve this requirement while keeping separate management of each department's VPC? (Choose two.)

A. Create an 1AM account for the cybersecurity department to manage both existing VPC, create a FortiGate HA Cluster on each VPC and IPSEC VPN to force traffic between the VPCs through the FortiGate clusters
B. Create a VPC with a FortiGate auto-scaling group with a Transit Gateway attached to the three VPC to force routing through the FortiGate cluster
C. Create a transit VPC with a FortiGate HA cluster, connect to the other two using VPC peering, and use routing tables to force traffic through the FortiGate cluster.
D. Migrate all the instances to the same VPC and create 1AM accounts for each department, then implement a new subnet for a FortiGate auto-scaling group and use routing tables to force the traffic through the FortiGate cluster.

正解：B、C

解説：
To implement security for the traffic between two VPCs in AWS, while keeping separate management of each department's VPC, two possible actions are:
Create a transit VPC with a FortiGate HA cluster, connect to the other two using VPC peering, and use routing tables to force traffic through the FortiGate cluster. This option allows the cybersecurity department to manage the transit VPC and apply security policies on the FortiGate cluster, while the other departments can manage their own VPCs and instances. The VPC peering connections enable direct communication between the VPCs without using public IPs or gateways. The routing tables can be configured to direct all inter-VPC traffic to the transit VPC.
Create a VPC with a FortiGate auto-scaling group with a Transit Gateway attached to the three VPCs to force routing through the FortiGate cluster. This option also allows the cybersecurity department to manage the security VPC and apply security policies on the FortiGate cluster, while the other departments can manage their own VPCs and instances. The Transit Gateway acts as a network hub that connects multiple VPCs and on-premises networks. The routing tables can be configured to direct all inter-VPC traffic to the security VPC. Reference: https://docs.fortinet.com/document/fortigate-public-cloud/7.2.0/aws-administration-guide/506140/connecting-a-local-fortigate-to-an-aws-vpc-vpn https://docs.fortinet.com/document/fortigate-public-cloud/7.0.0/sd-wan-architecture-for-enterprise/166334/sd-wan-configuration

質問 # 40
Refer to the exhibit, which shows a VPN topology.

The device IP 10.1.100.40 downloads a file from the FTP server IP 192.168.4.50 Referring to the exhibit, what will be the traffic flow behavior if ADVPN is configured in this environment?

A. ADVPN is not supported when spokes are behind NAT
B. All the session traffic will pass through the Hub
C. The TCP port 21 must be allowed on the NAT Device2
D. Spoke1 will establish an ADVPN shortcut to Spoke2

正解：D

解説：
D is correct because Spoke1 will establish an ADVPN shortcut to Spoke2 when it detects that there is a demand for traffic between them. This is explained in the Fortinet Community article on Technical Tip: Fortinet Auto Discovery VPN (ADVPN) under Summary - ADVPN sequence of events. Reference: https://community.fortinet.com/t5/FortiGate/Technical-Tip-Fortinet-Auto-Discovery-VPN-ADVPN/ta-p/195698

質問 # 43
A customer is planning on moving their secondary data center to a cloud-based laaS. They want to place all the Oracle-based systems Oracle Cloud, while the other systems will be on Microsoft Azure with ExpressRoute service to their main data center.
They have about 200 branches with two internet services as their only WAN connections. As a security consultant you are asked to design an architecture using Fortinet products with security, redundancy and performance as a priority.
Which two design options are true based on these requirements? (Choose two.)

A. Systems running on Azure will need to go through the main data center to access the services on Oracle Cloud.
B. Use FortiGate VM for IPSEC over ExpressRoute, as traffic is not encrypted by Azure.
C. Two ExpressRoute services to the main data center are required to implement SD-WAN between a FortiGate VM in Azure and a FortiGate device at the data center edge
D. Branch FortiGate devices must be configured as VPN clients for the branches' internal network to be able to access Oracle services without using public IPs.

正解：B、C

解説：
To secure the traffic between Azure and the main data center, a FortiGate VM can be deployed in Azure and configured to use IPSEC over ExpressRoute, as traffic is not encrypted by Azure by default. This also allows the use of Fortinet security features such as antivirus, IPS, web filtering, and application control. To implement SD-WAN between Azure and the main data center, two ExpressRoute services are required to provide redundant paths and load balancing. A FortiGate device at the data center edge can be configured to use SD-WAN rules to select the best path based on performance, availability, and cost.

質問 # 47
Refer to the exhibits.

A customer wants to deploy 12 FortiAP 431F devices on high density conference center, but they do not currently have any PoE switches to connect them to. They want to be able to run them at full power while having network redundancy From the FortiSwitch models and sample retail prices shown in the exhibit, which build of materials would have the lowest cost, while fulfilling the customer's requirements?

A. 1x FortiSwitch 248EFPOE
B. 2x FortiSwitch 124E-FPOE
C. 2x FortiSwitch 248E-FPOE
D. 2x FortiSwitch 224E-POE

正解：C

解説：
The customer wants to deploy 12 FortiAP 431F devices on a high density conference center, but they do not have any PoE switches to connect them to. They want to be able to run them at full power while having network redundancy. PoE switches are switches that can provide both data and power to connected devices over Ethernet cables, eliminating the need for separate power adapters or outlets. PoE switches are useful for deploying devices such as wireless access points, IP cameras, and VoIP phones in locations where power outlets are scarce or inconvenient. The FortiAP 431F is a wireless access point that supports PoE+ (IEEE 802.3at) standard, which can deliver up to 30W of power per port. The FortiAP 431F has a maximum power consumption of 25W when running at full power. Therefore, to run 12 FortiAP 431F devices at full power, the customer needs PoE switches that can provide at least 300W of total PoE power budget (25W x 12). The customer also needs network redundancy, which means that they need at least two PoE switches to connect the FortiAP devices in case one switch fails or loses power. From the FortiSwitch models and sample retail prices shown in the exhibit, the build of materials that has the lowest cost while fulfilling the customer's requirements is 2x FortiSwitch 248E-FPOE. The FortiSwitch 248E-FPOE is a PoE switch that has 48 GE ports with PoE+ capability and a total PoE power budget of 370W. It also has 4x 10 GE SFP+ uplink ports for high-speed connectivity. The sample retail price of the FortiSwitch 248E-FPOE is $1,995, which means that two units will cost $3,990. This is the lowest cost among the other options that can meet the customer's requirements. Option A is incorrect because the FortiSwitch 248EFPOE is a non-PoE switch that has no PoE capability or power budget. It cannot provide power to the FortiAP devices over Ethernet cables. Option B is incorrect because the FortiSwitch 224E-POE is a PoE switch that has only 24 GE ports with PoE+ capability and a total PoE power budget of 185W. It cannot provide enough ports or power to run 12 FortiAP devices at full power. Option D is incorrect because the FortiSwitch 124E-FPOE is a PoE switch that has only 24 GE ports with PoE+ capability and a total PoE power budget of 185W. It cannot provide enough ports or power to run 12 FortiAP devices at full power. Reference: https://www.fortinet.com/content/dam/fortinet/assets/data-sheets/FortiSwitch_Secure_Access_Series.pdf https://www.fortinet.com/content/dam/fortinet/assets/data-sheets/FortiAP_400_Series.pdf

質問 # 48
Review the following FortiGate-6000 configuration excerpt:

Based on the configuration, which statement is correct regarding SNAT source port partitioning behavior?

A. It dynamically distributes SNAT source ports to operating FPCs or FPMs.
B. It statically distributes SNAT source ports to operating FPCs or FPMs
C. It is the default SNAT configuration and preserves active sessions when an FPC or FPM goes down.
D. It equally distributes SNAT source ports across chassis slots.

正解：A

解説：
The configuration excerpt shows that the SNAT source port partitioning behavior is set to dynamic. This means that the FortiGate will dynamically distribute SNAT source ports to operating FPCs or FPMs. This ensures that active sessions are not interrupted if an FPC or FPM goes down.
The other options are incorrect. Option B is incorrect because the default SNAT configuration is static. Option C is incorrect because the configuration excerpt does not specify that SNAT source ports are statically distributed. Option D is incorrect because the SNAT source ports are not evenly distributed across chassis slots.
Here are some additional details about SNAT source port partitioning behavior:
SNAT source port partitioning behavior can be set to dynamic or static.
The default SNAT configuration is static.
Dynamic SNAT source port partitioning ensures that active sessions are not interrupted if an FPC or FPM goes down.
Static SNAT source port partitioning can improve performance by reducing the number of SNAT lookups.

質問 # 49
An automation stitch was configured using an incoming webhook as the trigger named 'my_incoming_webhook'. The action is configured to execute the CLI Script shown:

正解：A

解説：
To execute the CLI script shown using an incoming webhook as the trigger, the correct syntax for the curl command is: curl -X POST -H "Content-Type: application/json" -d '{"trigger_name":"my_incoming_webhook"}' https://fortisoar.example.com/api/v1/trigger This command will send a POST request to the FortiSOAR API endpoint with the trigger name and the content type as JSON. The FortiSOAR API will then execute the automation stitch that matches the trigger name and run the CLI script on the FortiGate device. Reference: https://docs.fortinet.com/document/fortisoar/7.0.0/administration-guide/103440/automation-stitches https://docs.fortinet.com/document/fortisoar/7.0.0/administration-guide/103441/incoming-webhook

質問 # 50
Refer to the exhibit.

The exhibit shows two error messages from a FortiGate root Security Fabric device when you try to configure a new connection to a FortiClient EMS Server.
Referring to the exhibit, which two actions will fix these errors? (Choose two.)

A. Export and import the FortiClient EMS server certificate to the root FortiGate.
B. Install a new known CA on the Win2K16-EMS server.
C. Verify that the CRL is accessible from the root FortiGate
D. Authorize the root FortiGate on the FortiClient EMS

正解：C、D

解説：
A is correct because the error message "The CRL is not accessible" indicates that the root FortiGate cannot access the CRL for the FortiClient EMS server. Verifying that the CRL is accessible will fix this error.
D is correct because the error message "The FortiClient EMS server is not authorized" indicates that the root FortiGate is not authorized to connect to the FortiClient EMS server. Authorizing the root FortiGate on the FortiClient EMS server will fix this error.
The other options are incorrect. Option B is incorrect because exporting and importing the FortiClient EMS server certificate to the root FortiGate will not fix the CRL error. Option C is incorrect because installing a new known CA on the Win2K16-EMS server will not fix the authorization error.

質問 # 51
You are running a diagnose command continuously as traffic flows through a platform with NP6 and you obtain the following output:

Given the information shown in the output, which two statements are true? (Choose two.)

A. There are packet drops at the XAUI.
B. Enabling bandwidth control between the ISF and the NP will change the output
C. Enable HPE shaper for the NP6 will change the output
D. Host-shortcut mode is enabled.
E. The output is showing a packet descriptor queue accumulated counter

正解：A、E

解説：
The diagnose command shown in the output is used to display information about NP6 packet descriptor queues. The output shows that there are 16 NP6 units in total, and each unit has four XAUI ports (XA0-XA3). The output also shows that there are some non-zero values in the columns PDQ ACCU (packet descriptor queue accumulated counter) and PDQ DROP (packet descriptor queue drop counter). These values indicate that there are some packet descriptor queues that have reached their maximum capacity and have dropped some packets at the XAUI ports. This could be caused by congestion or misconfiguration of the XAUI ports or the ISF (Internal Switch Fabric). References: https://docs.fortinet.com/document/fortigate/7.0.0/cli-reference/19662/diagnose-np6-pdq The output is showing a packet descriptor queue accumulated counter, which is a measure of the number of packets that have been dropped by the NP6 due to congestion. The counter will increase if there are more packets than the NP6 can handle, which can happen if the bandwidth between the ISF and the NP is not sufficient or if the HPE shaper is enabled.
The output also shows that there are packet drops at the XAUI, which is the interface between the NP6 and the FortiGate's backplane. This means that the NP6 is not able to keep up with the traffic and is dropping packets.
The other statements are not true. Host-shortcut mode is not enabled, and enabling bandwidth control between the ISF and the NP will not change the output. HPE shaper is a feature that can be enabled to improve performance, but it will not change the output of the diagnose command.

質問 # 55
Refer to the CLI output:

Given the information shown in the output, which two statements are correct? (Choose two.)

A. Attackers can be blocked before they target the servers behind the FortiWeb.
B. An IP address that was previously used by an attacker will always be blocked
C. Reputation from blacklisted IP addresses from DHCP or PPPoE pools can be restored
D. The IP Reputation feature has been manually updated
E. Geographical IP policies are enabled and evaluated after local techniques.

正解：A、C

解説：
The CLI output shown in the exhibit indicates that FortiWeb has enabled IP Reputation feature with local techniques enabled and geographical IP policies enabled after local techniques (set geoip-policy-order after- local). IP Reputation feature is a feature that allows FortiWeb to block or allow traffic based on the reputation score of IP addresses, which reflects their past malicious activities or behaviors. Local techniques are methods that FortiWeb uses to dynamically update its own blacklist based on its own detection of attacks or violations from IP addresses (such as signature matches, rate limiting, etc.). Geographical IP policies are rules that FortiWeb uses to block or allow traffic based on the geographical location of IP addresses (such as country, region, city, etc.). Therefore, based on the output, one correct statement is that attackers can be blocked before they target the servers behind the FortiWeb. This is because FortiWeb can use IP Reputation feature to block traffic from IP addresses that have a low reputation score or belong to a blacklisted location, which prevents them from reaching the servers and launching attacks. Another correct statement is that reputation from blacklisted IP addresses from DHCP or PPPoE pools can be restored. This is because FortiWeb can use local techniques to remove IP addresses from its own blacklist if they stop sending malicious traffic for a certain period of time (set local-techniques-expire-time), which allows them to regain their reputation and access the servers. This is useful for IP addresses that are dynamically assigned by DHCP or PPPoEand may change frequently. References: https://docs.fortinet.com/document/fortiweb/6.4.0/administration-guide/19662/ip- reputationhttps://docs.fortinet.com/document/fortiweb/6.4.0/administration-guide/19662/geographical-ip- policies
https://docs.fortinet.com/document/fortiweb/7.4.2/administration-guide/608374/ip-reputation-blocklisting- source-ips-with-poor-reputation Fortinet compiles a reputation for each public IP address. Clients will have poor reputations if they have been participating in attacks, willingly or otherwise. Because blacklisting innocent clients is equally undesirable, Fortinet also restores the reputations of clients that improve their behavior. This is crucial when an infected computer is cleaned, or in DHCP or PPPoE pools where an innocent client receives an IP address that was previously leased by an attacker.

質問 # 56
What is the benefit of using FortiGate NAC LAN Segments?

A. It provides support for IGMP snooping between hosts within the same VLAN
B. It provides support for multiple DHCP servers within the same VLAN.
C. It provides physical isolation without changing the IP address of hosts.
D. It allows for assignment of dynamic address objects matching NAC policy.

正解：D

解説：
FortiGate NAC LAN Segments are a feature that allows users to assign different VLANs to different LAN segments without changing the IP address of hosts or bouncing the switch port. This provides physical isolation while maintaining firewall sessions and avoiding DHCP issues. One benefit of using FortiGate NAC LAN Segments is that it allows for assignment of dynamic address objects matching NAC policy. This means that users can create firewall policies based on dynamic address objects that match the NAC policy criteria, such as device type, OS type, MAC address, etc. This simplifies firewall policy management and enhances security by applying different security profiles to different types of devices. Reference: https://docs.fortinet.com/document/fortigate/7.0.0/new-features/856212/nac-lan-segments-7-0-1

質問 # 57
You are responsible for recommending an adapter type for NICs on a FortiGate VM that will run on an ESXi Hypervisor. Your recommendation must consider performance as the main concern, cost is not a factor. Which adapter type for the NICs will you recommend?

A. Physical Function (PF) PCI Passthrough
B. Native ESXi Networking with VMXNET3
C. Native ESXi Networking with E1000
D. Virtual Function (VF) PCI Passthrough

正解：B

解説：
The FortiGate VM is a virtual firewall appliance that can run on various hypervisors, such as ESXi, Hyper-V, KVM, etc. The adapter type for NICs on a FortiGate VM determines the performance and compatibility of the network interface cards with the hypervisor and the physical network. There are different adapter types available for NICs on a FortiGate VM, such as E1000, VMXNET3, SR-IOV, etc. If performance is the main concern and cost is not a factor, one option is to use native ESXi networking with VMXNET3 adapter type for NICs on a FortiGate VM that will run on an ESXi hypervisor. VMXNET3 is a paravirtualized network interface card that is optimized for performance in virtual machines and supports features such as multiqueue support, Receive Side Scaling (RSS), Large Receive Offload (LRO), IPv6 offloads, and MSI/MSI-X interrupt delivery. Native ESXi networking means that the FortiGate VM uses the standard virtual switch (vSwitch) or distributed virtual switch (dvSwitch) provided by the ESXi hypervisor to connect to the physical network. This option can provide high performance and compatibility for NICs on a FortiGate VM without requiring additional hardware or software components.
