質問 # 31
You want to use the MTA adapter feature on FortiSandbox in an HA-Cluster. Which statement about this solution is true?

  • A. The configuration of the MTA Adapter Local Interface is different than on port1.
  • B. The MTA adapter mode is only detection mode.
  • C. The configuration is different than on a standalone device.
  • D. The MTA adapter is only available in the primary node.

正解:D

解説:
The MTA adapter feature on FortiSandbox is a feature that allows FortiSandbox to act as a mail transfer agent (MTA) that can receive, inspect, and forward email messages from external sources. The MTA adapter feature can be used to integrate FortiSandbox with third-party email security solutions that do not support direct integration with FortiSandbox, such as Microsoft Exchange Server or Cisco Email Security Appliance (ESA). The MTA adapter feature can also be used to enhance email security by adding an additional layer of inspection and filtering before delivering email messages to the final destination. The MTA adapter feature can be enabled on FortiSandbox in an HA-Cluster, which is a configuration that allows two FortiSandbox units to synchronize their settings and data and provide high availability and load balancing for sandboxing services. However, one statement about this solution that is true is that the MTA adapter is only available in the primary node. This means that only one FortiSandbox unit in the HA-Cluster can act as an MTA and receive email messages from external sources, while the other unit acts as a backup node that can take over the MTA role if the primary node fails or loses connectivity. This also means that only one IP address or FQDN can be used to configure the external sources to send email messages to the FortiSandbox MTA, which is the IP address or FQDN of the primary node.

質問 # 32
Refer to the CLI configuration of an SSL inspection profile from a FortiGate device configured to protect a web server:

Based on the information shown, what is the expected behavior when an HTTP/2 request comes in?

  • A. FortiGate will reject all HTTP/2 ALPN headers.
  • B. FortiGate will forward the traffic without modifying the ALPN header.
  • C. FortiGate will strip the ALPN header and forward the traffic.
  • D. FortiGate will rewrite the ALPN header to request HTTP/1.

正解:A

解説:
The supported-alpn parameter is set to http1.1 in the SSL inspection profile. This means that the FortiGate will only accept HTTP/1.1 traffic. Any HTTP/2 traffic will be rejected.
The following is the relevant documentation from Fortinet:
The supported-alpn parameter specifies the list of ALPN protocols that the FortiGate will accept. If the client requests a protocol that is not in this list, the FortiGate will reject the connection.
The default value for the supported-alpn parameter is all. This means that the FortiGate will accept any ALPN protocol that the client requests.
To reject all HTTP/2 traffic, set the supported-alpn parameter to http1.1.

質問 # 33
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 the ISL and FortiLink trunks
  • C. enable on the ISL and FortiLink trunks
  • D. disable on ICL trunks

正解:B、D

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 # 34
Refer to the exhibit.

A customer has deployed a FortiGate 300E with virtual domains (VDOMs) enabled in the multi-VDOM mode. There are three VDOMs: Root is for management and internet access, while VDOM 1 and VDOM 2 are used for segregating internal traffic. AccountVInk and SalesVInk are standard VDOM links in Ethernet mode.
Given the exhibit, which two statements below about VDOM behavior are correct? (Choose two.)

  • A. Root VDOM is an Admin type VDOM, while VDOM 1 and VDOM 2 are Traffic type VDOMs.
  • B. OSPF routing can be configured between VDOM 1 and Root VDOM without any configuration changes to AccountVInk
  • C. The VDOM links are in Ethernet mode because they have IP addressed assigned on both sides.
  • D. Traffic on AccountVInk and SalesVInk will not be accelerated.
  • E. You can apply OSPF routing on the VDOM link in either PPP or Ethernet mode

正解:A、D

解説:
The FortiGate configuration shown in the exhibit is using virtual domains (VDOMs) enabled in multi-VDOM mode. There are three VDOMs: Root is for management and internet access, while VDOM 1 and VDOM 2 are used for segregating internal traffic. AccountVInk and SalesVInk are standard VDOM links in Ethernet mode. One correct statement about VDOM behavior is that traffic on AccountVInk and SalesVInk will not be accelerated. This is because standard VDOM links do not support hardware acceleration features such as NP6 or CP9 offloading, which can improve performance and throughput for traffic between VDOMs. To enable hardware acceleration for inter-VDOM traffic, non-standard VDOM links such as NP6 or CP9 interfaces should be used instead of standard VDOM links. Another correct statement about VDOM behavior is that Root VDOM is an Admin type VDOM, while VDOM 1 and VDOM 2 are Traffic type VDOMs. This is because Admin type VDOMs are special VDOMs that can only be used for management purposes and cannot process any traffic other than management traffic (such as SSH, HTTPS, SNMP, etc.). Traffic type VDOMs are normal VDOMs that can process any kind of traffic (such as firewall policies, VPN tunnels, routing protocols, etc.). By default, Root VDOM is an Admin type VDOM that can manage other Traffic type VDOMs, unless it is converted to a Traffic type VDOM by using the set vdom-admin enable command.

質問 # 35
Which two methods are supported for importing user defined Lookup Table Data into the FortiSIEM? (Choose two.)

  • A. FTP
  • B. API
  • C. SCP
  • D. Report

正解:B、D

解説:
FortiSIEM supports two methods for importing user defined Lookup Table Data:
Report: You can import lookup table data from a report. This is the most common method for importing lookup table data.
API: You can also import lookup table data using the FortiSIEM API. This is a more advanced method that allows you to import lookup table data programmatically.
FTP, SCP, and other file transfer protocols are not supported for importing lookup table data into FortiSIEM.


質問 # 36
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 not 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 been stopped by FortiEDR

正解:B

解説:
The exhibit shows that the FortiEDR core has detected an exfiltration attack. The attack is attempting to copy files from the device to an external location. The FortiEDR core has blocked the attack, and the files have not been exfiltrated.
The exhibit also shows that the attack is using the Cobalt Strike beacon. Cobalt Strike is a penetration testing tool that can be used for both legitimate and malicious purposes. In this case, the Cobalt Strike beacon is being used to exfiltrate files from the device.
The other options are incorrect. Option A is incorrect because the attack has not been stopped. Option C is incorrect because the attack is not a ransomware attack. Option D is incorrect because the FortiEDR core has not stopped the attack.

質問 # 37
You are troubleshooting a FortiMail Cloud service integrated with Office 365 where outgoing emails are not reaching the recipients' mail What are two possible reasons for this problem? (Choose two.)

  • A. The FortiMail access control rules to relay from Office 365 servers public IPs are missing.
  • B. A Mail Flow connector from the Exchange Admin Center has not been set properly to the FortiMail Cloud FQDN.
  • C. The FortiMail access control rule to relay from Office 365 servers FQDN is missing.
  • D. The FortiMail DKIM key was not set using the Auto Generation option.

正解:A、B

解説:
FortiMail Cloud service is a cloud-based email security solution that integrates with Office 365 to provide protection against spam, malware, phishing, data loss, etc. To use FortiMail Cloud service with Office 365, users need to configure both FortiMail Cloud settings and Office 365 settings properly. One possible reason for outgoing emails not reaching the recipients' mailboxes is that the FortiMail access control rules to relay from Office 365 servers public IPs are missing. This means that FortiMail Cloud service does not recognize the Office 365 servers as authorized senders and rejects the outgoing emails. Users need to add the Office 365 servers public IPs to the FortiMail access control rules to allow relaying. Another possible reason for outgoing emails not reaching the recipients' mailboxes is that a Mail Flow connector from the Exchange Admin Center has not been set properly to the FortiMail Cloud FQDN. This means that Office 365 does not route the outgoing emails to the FortiMail Cloud service for scanning and delivery. Users need to create a Mail Flow connector from the Exchange Admin Center and specify the FortiMail Cloud FQDN as the smart host. Reference: https://docs.fortinet.com/document/fortimail-cloud/6.4.0/administration-guide/19662/integrating-fortimail-cloud-with-office-365


質問 # 38
Refer to the exhibit showing the history logs from a FortiMail device.

Which FortiMail email security feature can an administrator enable to treat these emails as spam?

  • A. Sender domain validation in a session profile
  • B. Impersonation analysis in an antispam profile
  • C. DKIM validation in a session profile
  • D. Soft fail SPF validation in an antispam profile

正解:B

解説:
Impersonation analysis is a feature that detects emails that attempt to impersonate a trusted sender, such as a company executive or a well-known brand, by using spoofed or look-alike email addresses. This feature can help prevent phishing and business email compromise (BEC) attacks. Impersonation analysis can be enabled in an antispam profile and applied to a firewall policy. References: https://docs.fortinet.com/document/fortimail/6.4.0/administration-guide/103663/impersonation-analysis


質問 # 39
Review the following FortiGate-6000 configuration excerpt:

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

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

正解:C

解説:
Based on the configuration, the statement that is correct regarding SNAT source port partitioning behavior is that it statically distributes SNAT source ports to operating FPCs or FPMs. This is because the nat-source-port option is set to chassis-slots, which means that the FortiGate-6000 will allocate SNAT source ports to all FPCs or FPMs that are enabled when the command is entered. If an FPC or FPM is disabled from the CLI, the SNAT source ports assigned to that FPC or FPM will not be re-allocated to the remaining FPCs or FPMs. This option preserves active sessions when an FPC or FPM goes down, but does not dynamically re-distribute SNAT source ports if an FPC or FPM is powered off. Reference: https://docs.fortinet.com/document/fortigate/7.2.5/fortigate-6000-administration-guide/81276/controlling-snat-port-partitioning-behavior


質問 # 40
Refer to the exhibit.

A customer has deployed a FortiGate 300E with virtual domains (VDOMs) enabled in the multi-VDOM mode. There are three VDOMs: Root is for management and internet access, while VDOM 1 and VDOM 2 are used for segregating internal traffic. AccountVInk and SalesVInk are standard VDOM links in Ethernet mode.
Given the exhibit, which two statements below about VDOM behavior are correct? (Choose two.)

  • A. You can apply OSPF routing on the VDOM link in either PPP or Ethernet mode
  • B. Root VDOM is an Admin type VDOM, while VDOM 1 and VDOM 2 are Traffic type VDOMs.
  • C. Traffic on AccountVInk and SalesVInk will not be accelerated.
  • D. OSPF routing can be configured between VDOM 1 and Root VDOM without any configuration changes to AccountVInk
  • E. The VDOM links are in Ethernet mode because they have IP addressed assigned on both sides.

正解:A、B

解説:
a) You can apply OSPF routing on the VDOM link in either PPP or Ethernet mode. This is because VDOM links can be configured in either PPP or Ethernet mode, and OSPF routing can be configured on both types of links.
d) Root VDOM is an Admin type VDOM, while VDOM 1 and VDOM 2 are Traffic type VDOMs. This is because the Root VDOM is the default VDOM, and it is used for management and internet access. VDOM 1 and VDOM 2 are traffic type VDOMs, which are used for segregating internal traffic.
The other options are not correct.
b) Traffic on AccountVInk and SalesVInk will not be accelerated. This is because VDOM links are not accelerated by default. However, you can configure acceleration on VDOM links if you want.
c) The VDOM links are in Ethernet mode because they have IP addressed assigned on both sides. This is not necessarily true. The VDOM links could be in PPP mode even if they have IP addresses assigned on both sides.
e) OSPF routing can be configured between VDOM 1 and Root VDOM without any configuration changes to AccountVInk. This is correct. OSPF routing can be configured between any two VDOMs, even if they are not directly connected. In this case, the OSPF routing would be configured on the AccountVInk link.


質問 # 41
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 equally distributes SNAT source ports across chassis slots.
  • C. It is the default SNAT configuration and preserves active sessions when an FPC or FPM goes down.
  • D. It statically distributes SNAT source ports to operating FPCs or FPMs

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 # 42
You are troubleshooting a FortiMail Cloud service integrated with Office 365 where outgoing emails are not reaching the recipients' mail What are two possible reasons for this problem? (Choose two.)

  • A. A Mail Flow connector from the Exchange Admin Center has not been set properly to the FortiMail Cloud FQDN.
  • B. The FortiMail access control rules to relay from Office 365 servers public IPs are missing.
  • C. The FortiMail access control rule to relay from Office 365 servers FQDN is missing.
  • D. The FortiMail DKIM key was not set using the Auto Generation option.

正解:A、C

解説:
a) The FortiMail access control rule to relay from Office 365 servers FQDN is missing.
If the access control rule to relay from Office 365 servers FQDN is missing, then FortiMail will not be able to send emails to Office 365. This is because the access control rule specifies which IP addresses or domains are allowed to relay emails through FortiMail.
b) A Mail Flow connector from the Exchange Admin Center has not been set properly to the FortiMail Cloud FQDN.
If the Mail Flow connector from the Exchange Admin Center is not set properly to the FortiMail Cloud FQDN, then Office 365 will not be able to send emails to FortiMail. This is because the Mail Flow connector specifies which SMTP server is used to send emails to external recipients.


質問 # 43
Refer to the exhibit.

A FortiWeb appliance is configured for load balancing web sessions to internal web servers. The Server Pool is configured as shown in the exhibit.
How will the sessions be load balanced between server 1 and server 2 during normal operation?

  • A. Server 1 will receive 20% of the sessions, Server 2 will receive 66.6% of the sessions
  • B. Server 1 will receive 33.3% of the sessions, Server 2 will receive 66 6% of the sessions
  • C. Server 1 will receive 25% of the sessions, Server 2 will receive 75% of the sessions
  • D. Server 1 will receive 0% of the sessions Server 2 will receive 100% of the sessions

正解:D

解説:
D is correct because server 1 has a weight of 0, which means it will not receive any sessions from the load balancer. Server 2 has a weight of 100, which means it will receive all sessions from the load balancer. This is explained in the FortiWeb Administration Guide under Server Load Balancing > Server pools > Weighted round robin. Reference: https://docs.fortinet.com/document/fortiweb/6.3.0/administration-guide/381057/server-load-balancing https://docs.fortinet.com/document/fortiweb/6.3.0/administration-guide/381057/server-load-balancing/381058/server-pools


質問 # 44
Refer to the exhibit, which shows the high availability configuration for the FortiAuthenticator (FAC1).

Based on this information, which statement is true about the next FortiAuthenticator (FAC2) member that will join an HA cluster with this FortiAuthenticator (FAC1)?

  • A. FSSO sessions from FAC1 will be synchronized to FAC2.
  • B. FAC2 can only process requests when FAC1 fails.
  • C. The FortiToken license will need to be installed on the FAC2.
  • D. FAC2 can have its HA interface on a different network than FAC1.

正解:A

解説:
When FortiAuthenticator operates in cluster mode, it provides active-passive failover and synchronization of all configuration and data, including FSSO sessions, between the cluster members. Therefore, if FAC1 is the active unit and FAC2 is the standby unit, any FSSO sessions from FAC1 will be synchronized to FAC2. If FAC1 fails, FAC2 will take over the active role and continue to process the FSSO sessions. Reference: https://docs.fortinet.com/document/fortiauthenticator/6.1.2/administration-guide/122076/high-availability


質問 # 45
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:

  • A.
  • B.
  • C.
  • D.

正解:B

解説:
The CLI script in option A will send the log message to the webhook server. The webhook server can then be configured to take any desired action, such as storing the log message in a database or sending an email notification.
The other options are incorrect. Option B will not send the log message to the webhook server because it does not contain the curl command. Option C will send the log message to the webhook server, but it will also include the FortiGate's IP address and MAC address. This information is not necessary, and it could be used by an attacker to identify the FortiGate. Option D will not send the log message to the webhook server because it does not contain the webhook action.

質問 # 46
Refer to the exhibit.

You have deployed a security fabric with three FortiGate devices as shown in the exhibit. FGT_2 has the following configuration:

FGT_1 and FGT_3 are configured with the default setting. Which statement is true for the synchronization of fabric-objects?

  • A. Objects from the root FortiGate will not be synchronized to any downstream FortiGate.
  • B. Objects from the root FortiGate will only be synchronized to FGT__2.
  • C. Objects from the FortiGate FGT_2 will be synchronized to the upstream FortiGate.
  • D. Objects from the root FortiGate will only be synchronized to FGT_3.

正解:C

解説:
The security fabric shown in the exhibit consists of three FortiGate devices connected in a hierarchical topology, where FGT_1 is the root device, FGT_2 is a downstream device, and FGT_3 is a downstream device of FGT_2. FGT_2 has a configuration setting that enables fabric-object synchronization for all objects except firewall policies and firewall policy packages (set sync-fabric-objects enable). Fabric-object synchronization is a feature that allows downstream devices to synchronize their objects (such as addresses, services, schedules, etc.) with their upstream devices in a security fabric. This simplifies object management and ensures consistency across devices. Therefore, in this case, objects from FGT_2 will be synchronized to FGT_1 (the upstream device), but not to FGT_3 (the downstream device). Objects from FGT_1 will not be synchronized to any downstream device because the default setting for fabric-object synchronization is disabled. Objects from FGT_3 will not be synchronized to any device because it does not have fabric-object synchronization enabled.

A customer is trying to set up a VPN with a FortiGate, but they do not have a backup of the configuration. Output during a troubleshooting session is shown in the exhibits A and B and a baseline VPN configuration is shown in Exhibit C Referring to the exhibits, which configuration will restore VPN connectivity?

  • A.
  • B.
  • C.
  • D.

正解:A

解説:
The VPN configuration shown in Exhibit C is a baseline VPN configuration that uses IKEv2 with pre-shared keys and AES256 encryption for both IKE and ESP phases. However, this configuration does not match the output shown in Exhibit A and B, which indicate that IKEv1 is used with RSA signatures and AES128 encryption for both IKE and ESP phases. Therefore, to restore VPN connectivity, the configuration needs to be modified to match these parameters. Option B shows the correct configuration that matches these parameters. Option A is incorrect because it still uses IKEv2 instead of IKEv1. Option C is incorrect because it still uses pre-shared keys instead of RSA signatures. Option D is incorrect because it still uses AES256 encryption instead of AES128 encryption. Reference: https://docs.fortinet.com/document/fortigate/7.0.0/cookbook/19662/ipsec-vpn-with-forticlient


質問 # 48
Review the VPN configuration shown in the exhibit.

What is the Forward Error Correction behavior if the SD-WAN network traffic download is 500 Mbps and has 8% of packet loss in the environment?

  • A. 2 redundant packet for every 8 base packets
  • B. 3 redundant packet for every 5 base packets
  • C. 3 redundant packet for every 9 base packets
  • D. 1 redundant packet for every 10 base packets

正解:A

解説:
The FEC configuration in the exhibit specifies that if the packet loss is greater than 10%, then the FEC mapping will be 8 base packets and 2 redundant packets. The download bandwidth of 500 Mbps is not greater than 950 Mbps, so the FEC mapping is not overridden by the bandwidth setting. Therefore, the FEC behavior will be 2 redundant packets for every 8 base packets.
Here is the explanation of the FEC mappings in the exhibit:
Packet loss greater than 10%: 8 base packets and 2 redundant packets.
Upload bandwidth greater than 950 Mbps: 9 base packets and 3 redundant packets.
The mappings are matched from top to bottom, so the first mapping that matches the conditions will be used. In this case, the first mapping matches because the packet loss is greater than 10%. Therefore, the FEC behavior will be 2 redundant packets for every 8 base packets.


質問 # 49
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. Change the priority of FMG-A to be numerically lower for higher preference
  • B. Make the monitored IP to match on both FortiManager devices.
  • C. Unset the primary and secondary roles in the FortiManager CLI configuration so VRRP will decide who is primary.
  • D. Change the FortiManager IP address on the managed FortiGate to 10.3.106.65.

正解:B

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.
