質問 # 10
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 an exfiltration attack and has been stopped by FortiEDR.
B. This is an exfiltration attack and has not been stopped by FortiEDR
C. This is a ransomware attack and has not been stopped by FortiEDR.
D. This is a ransomware attack and has been stopped by FortiEDR

正解：D

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 # 11
You must analyze an event that happened at 20:37 UTC. One log relevant to the event is extracted from FortiGate logs:

The devices and the administrator are all located in different time zones Daylight savings time (DST) is disabled
* The FortiGate is at GMT-1000.
* The FortiAnalyzer is at GMT-0800
* Your browser local time zone is at GMT-03.00
You want to review this log on FortiAnalyzer GUI, what time should you use as a filter?

A. 12.37:08
B. 17:37:08
C. 20:37:08
D. 10:37:08

正解：B

解説：
To review this log on FortiAnalyzer GUI, the administrator should use the time filter that matches the local time zone of FortiAnalyzer, which is GMT-0800. Since the log was generated at 20:37 UTC (GMT+0000), the corresponding time in GMT-0800 is 20:37 - 8 hours = 12:37. However, since DST is disabled on FortiAnalyzer, the administrator should add one hour to account for daylight saving time difference, resulting in 12:37 + 1 hour = 13:37. Therefore, the time filter to use is 13:37:08. Reference: https://docs.fortinet.com/document/fortianalyzer/6.4.0/administration-guide/103664/time-zone-and-daylight-saving-time

質問 # 12
A remote IT Team is in the process of deploying a FortiGate in their lab. The closed environment has been configured to support zero-touch provisioning from the FortiManager, on the same network, via DHCP options. After waiting 15 minutes, they are reporting that the FortiGate received an IP address, but the zero-touch process failed.
The exhibit below shows what the IT Team provided while troubleshooting this issue:

Which statement explains why the FortiGate did not install its configuration from the FortiManager?

A. The FortiGate was not configured with the correct pre-shared key to connect to the FortiManager
B. The configuration was modified on the FortiGate prior to connecting to the FortiManager
C. The DHCP server was not configured with the FQDN of the FortiManager
D. The DHCP server used the incorrect option type for the FortiManager IP address.

正解：D

解説：
C is correct because the DHCP server used the incorrect option type for the FortiManager IP address. The option type should be 43 instead of 15, as shown in the FortiManager Administration Guide under Zero-Touch Provisioning > Configuring DHCP options for ZTP. References: 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 # 13
Refer to the exhibit.

You are operating an internal network with multiple OSPF routers on the same LAN segment. FGT_3 needs to be added to the OSPF network and has the configuration shown in the exhibit. FGT_3 is not establishing any OSPF connection.
What needs to be changed to the configuration to make sure FGT_3 will establish OSPF neighbors without affecting the DR/BDR election?

正解：D

解説：
The OSPF configuration shown in the exhibit is using the default priority value of 1 for the interface port1. This means that FGT_3 will participate in the DR/BDR election process with the other OSPF routers on the same LAN segment. However, this is not desirable because FGT_3 is a new device that needs to be added to the OSPF network without affecting the existing DR/BDR election. Therefore, to make sure FGT_3 will establish OSPF neighbors without affecting the DR/BDR election, the priority value of the interface port1 should be changed to 0. This will prevent FGT_3 from becoming a DR or BDR and allow it to form OSPF adjacencies with the current DR and BDR. Option B shows the correct configuration that changes the priority value to 0. Option A is incorrect because it does not change the priority value. Option C is incorrect because it changes the network type to point-to-point, which is not suitable for a LAN segment with multiple OSPF routers. Option D is incorrect because it changes the area ID to 0.0.0.1, which does not match the area ID of the other OSPF routers on the same LAN segment. References: https://docs.fortinet.com/document/fortigate/7.0.0/administration-guide/358640/basic-ospf-example

質問 # 14
You are migrating the branches of a customer to FortiGate devices. They require independent routing tables on the LAN side of the network.
After reviewing the design, you notice the firewall will have many BGP sessions as you have two data centers (DC) and two ISPs per DC while each branch is using at least 10 internal segments.
Based on this scenario, what would you suggest as the more efficient solution, considering that in the future the number of internal segments, DCs or internet links per DC will increase?

A. No change in design is needed as even small FortiGate devices have a large memory capacity.
B. Redesign the SD-WAN deployment to only use a single VPN tunnel and segment traffic using VRFs on BGP
C. Implement network-id, neighbor-group and increase the advertisement-interval
D. Acquire a FortiGate model with more capacity, considering the next 5 years growth.

正解：B

解説：
Using multiple VPN tunnels and BGP sessions for each internal segment is not scalable and efficient, especially when the number of segments, DCs or internet links per DC increases. A better solution is to use a single VPN tunnel per branch and segment traffic using virtual routing and forwarding (VRF) instances on BGP. This way, each VRF can have its own routing table and BGP session, while sharing the same VPN tunnel. References: https://docs.fortinet.com/document/fortigate/6.4.0/cookbook/103439/sd-wan-with-vrf-and-bgp

質問 # 15
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 9 base packets
C. 1 redundant packet for every 10 base packets
D. 3 redundant packet for every 5 base packets

正解：D

解説：
Forward Error Correction (FEC) is a feature that can improve the quality of SD-WAN network traffic by adding redundant packets to the original packets. The ratio of redundant packets to base packets is determined by the FEC mode, which can be set to low, medium, or high. In low mode, the ratio is 1:10, in medium mode, the ratio is 2:8, and in high mode, the ratio is 3:5. The FEC mode can be configured manually or automatically based on the bandwidth and packet loss of the network. In this case, since the download bandwidth is 500 Mbps and the packet loss is 8%, the FEC mode is automatically set to high, which means that 3 redundant packets are added for every 5 base packets. Reference: https://docs.fortinet.com/document/fortigate/7.0.0/sd-wan/19662/forward-error-correction-fec

質問 # 16
On a FortiGate Configured in Transparent mode, which configuration option allows you to control Multicast traffic passing through the?

正解：B

解説：
To control multicast traffic passing through a FortiGate configured in transparent mode, you can use multicast policies. Multicast policies allow you to filter multicast traffic based on source and destination addresses, protocols, and interfaces. You can also apply security profiles to scan multicast traffic for threats and violations. References: https://docs.fortinet.com/document/fortigate/6.2.14/cookbook/968606/configuring-multicast-forwarding

質問 # 17
Which two statements are correct on a FortiGate using the FortiGuard Outbreak Protection Service (VOS)? (Choose two.)

A. The AV engine scan must be enabled to use the FortiGuard VOS feature
B. If third-party AV database returns a match the scanned file is deemed to be malicious.
C. The FortiGuard VOS can be used only with proxy-base policy inspections.
D. The hash signatures are obtained from the FortiGuard Global Threat Intelligence database.
E. The antivirus database queries FortiGuard with the hash of a scanned file

正解：D、E

解説：
The FortiGuard Outbreak Prevention Service (VOS) is a feature that enhances the antivirus scanning capabilities of FortiGate by querying FortiGuard with the hash of a scanned file that is not found in the local antivirus database. If the hash matches a signature in the FortiGuard Global Threat Intelligence database, which contains information about known malware and zero-day threats, the file is deemed to be malicious and blocked by FortiGate. The VOS feature can be used with both proxy-based and flow-based policy inspections, and does not require the AV engine scan to be enabled. Reference: https://docs.fortinet.com/document/fortigate/6.2.14/cookbook/968606/outbreak-prevention-service

質問 # 18
Refer to the exhibits.

A customer has deployed a FortiGate with iBGP and eBGP routing enabled. HQ is receiving routes over eBGP from ISP 2; however, only certain routes are showing up in the routing table-Assume that BGP is working perfectly and that the only possible modifications to the routing table are solely due to the prefix list that is applied on HQ.
Given the exhibits, which two routes will be active in the routing table on the HQ firewall? (Choose two.)

A. 172,620,64,27
B. 172.16.201.96/29
C. 172.16.204.128/25
D. 172.16.204.64/27

正解：C、D

解説：
The prefix list in the exhibit is configured to match prefixes that are either in the 172.16.204.0/24 subnet or in the 172.62.0.0/16 subnet. The routes that match these prefixes will be active in the routing table on the HQ firewall.
The routes that match the following prefixes will not be active in the routing table:
172.16.201.96/29
172.62.0.64/27
These routes do not match the criteria set by the prefix list.

質問 # 19
Refer to the exhibit containing the configuration snippets from the FortiGate. Customer requirements:

* SSLVPN Portal must be accessible on standard HTTPS port (TCP/443)
* Public IP address (129.11.1.100) is assigned to portl
* Datacenter.acmecorp.com resolves to the public IP address assigned to portl The customer has a Let's Encrypt certificate that is going to expire soon and it reports that subsequent attempts to renew that certificate are failing.
Reviewing the requirement and the exhibit, which configuration change below will resolve this issue?
A)

B)

C)

A. Option C
B. Option B
C. Option D
D. Option A

正解：B

解説：
The customer's SSLVPN Portal is currently configured to use a self-signed certificate. This means that the certificate is not trusted by any browsers, and users will have to accept a security warning before they can connect to the portal.
To resolve this issue, the customer needs to configure the FortiGate to use a Let's Encrypt certificate. Let's Encrypt is a free certificate authority that provides trusted certificates for websites and other applications.
The configuration change in option B will configure the FortiGate to use a Let's Encrypt certificate for the SSLVPN Portal. This will allow users to connect to the portal without having to accept a security warning.
The other configuration changes are not necessary to resolve the issue. Option A will configure the FortiGate to use a different port for the SSLVPN Portal, but this will not resolve the issue with the self-signed certificate. Option C will configure the FortiGate to use a different DNS name for the SSLVPN Portal, but this will also not resolve the issue with the self-signed certificate. Option D will configure the FortiGate to use a different certificate authority for the SSLVPN Portal, but this will also not resolve the issue because the customer still needs to use a trusted certificate.

質問 # 20
You are creating the CLI script to be used on a new SD-WAN deployment You will have branches with a different number of internet connections and want to be sure there is no need to change the Performance SLA configuration in case more connections are added to the branch.
The current configuration is:

Which configuration do you use for the Performance SLA members?

A. set members 0
B. set members any
C. current configuration already fulfills the requirement
D. set members all

正解：B

解説：
The set members any option will ensure that all of the SD-WAN interfaces are included in the Performance SLA. This is the best option if you want to be sure that the Performance SLA will be triggered even if more connections are added to the branch in the future.
The set members 0 option will exclude all of the SD-WAN interfaces from the Performance SLA. This is not a good option because it will prevent the Performance SLA from being triggered even if there is a problem with the network.
The current configuration already fulfills the requirement option is incorrect because it does not ensure that all of the SD-WAN interfaces will be included in the Performance SLA.
The set members all option will include all of the SD-WAN interfaces in the Performance SLA, but it is not the best option because it is not scalable. If you have a large number of SD-WAN interfaces, this option will cause the Performance SLA to be triggered too often.

質問 # 21
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. The VDOM links are in Ethernet mode because they have IP addressed assigned on both sides.
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. You can apply OSPF routing on the VDOM link in either PPP or Ethernet mode

正解：B、E

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 # 22
Refer to the exhibit.

You have been tasked with replacing the managed switch Forti Switch 2 shown in the topology.
Which two actions are correct regarding the replacement process? (Choose two.)

A. CLAG-ICL needs to be manually reconfigured once the new switch is connected to the FortiGate
B. After replacing the FortiSwitch unit, the automatically created trunk name changes.
C. MCLAG-ICL will be automatically reconfigured once the new switch is connected to the FortiGate.
D. After replacing the FortiSwitch unit, the automatically created trunk name does not change

正解：C、D

解説：
Based on the exhibit, the two correct actions regarding the replacement process are:
After replacing the FortiSwitch unit, the automatically created trunk name does not change. This is because the trunk name is based on the slot number and port number of the FortiGate unit that connects to the FortiSwitch unit, which remain the same after the replacement. If a different trunk name is desired, the trunk must be deleted and a new trunk will be created automatically with an updated name.
MCLAG-ICL will be automatically reconfigured once the new switch is connected to the FortiGate. This is because the MCLAG-ICL configuration is stored on the FortiGate unit and applied to the FortiSwitch unit when it is authorized. The replacement FortiSwitch unit will inherit the MCLAG-ICL configuration of the failed FortiSwitch unit after it is replaced using the replace-device command in FortiOS.

質問 # 23
Review the following FortiGate-6000 configuration excerpt:

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

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

正解：B

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 # 24
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. Spoke1 will establish an ADVPN shortcut to Spoke2
B. All the session traffic will pass through the Hub
C. The TCP port 21 must be allowed on the NAT Device2
D. ADVPN is not supported when spokes are behind NAT

正解：A

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. References: https://community.fortinet.com/t5/FortiGate/Technical-Tip-Fortinet-Auto-Discovery-VPN-ADVPN/ta-p/195698

質問 # 25
Refer to the exhibits.

A customer is looking for a solution to authenticate the clients connected to a hardware switch interface of a FortiGate 400E.
Referring to the exhibits, which two conditions allow authentication to the client devices before assigning an IP address? (Choose two.)

A. Devices connected directly to ports 3 and 4 can perform 802 1X authentication.
B. FortiGate devices with NP6 and hardware switch interfaces cannot support 802.1X authentication.
C. Client devices must have 802 1X authentication enabled
D. Ports 3 and 4 can be part of different switch interfaces.

正解：A、C

解説：
The customer wants to deploy a solution to authenticate the clients connected to a hardware switch interface of a FortiGate 400E device. A hardware switch interface is an interface that combines multiple physical interfaces into one logical interface, allowing them to act as a single switch with one IP address and one set of security policies. The customer wants to use 802.1X authentication for this solution, which is a standard protocol for port-based network access control (PNAC) that authenticates clients based on their credentials before granting them access to network resources. One condition that allows authentication to the client devices before assigning an IP address is that devices connected directly to ports 3 and 4 can perform 802.1X authentication. This is because ports 3 and 4 are part of the hardware switch interface named "lan", which has an IP address of 10.10.10.254/24 and an inbound SSL inspection profile named "ssl-inspection". The inbound SSL inspection profile enables the FortiGate device to intercept and inspect SSL/TLS traffic from clients before forwarding it to servers, which allows it to apply security policies and features such as antivirus, web filtering, application control, etc. However, before performing SSL inspection, the FortiGate device needs to authenticate the clients using 802.1X authentication, which requires the clients to send their credentials (such as username and password) to the FortiGate device over a secure EAP (Extensible Authentication Protocol) channel. The FortiGate device then verifies the credentials with an authentication server (such as RADIUS or LDAP) and grants or denies access to the clients based on the authentication result. Therefore, devices connected directly to ports 3 and 4 can perform 802.1X authentication before assigning an IP address. Another condition that allows authentication to the client devices before assigning an IP address is that client devices must have 802.1X authentication enabled. This is because 802.1X authentication is a mutual process that requires both the client devices and the FortiGate device to support and enable it. The client devices must have 802.1X authentication enabled in their network settings, which allows them to initiate the authentication process when they connect to the hardware switch interface of the FortiGate device. The client devices must also have an 802.1X supplicant software installed, which is a program that runs on the client devices and handles the communication with the FortiGate device using EAP messages. The client devices must also have a trusted certificate installed, which is used to verify the identity of the FortiGate device and establish a secure EAP channel. Therefore, client devices must have 802.1X authentication enabled before assigning an IP address.

質問 # 26
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 # 27
A customer with a FortiDDoS 200F protecting their fibre optic internet connection from incoming traffic sees that all the traffic was dropped by the device even though they were not under a DoS attack. The traffic flow was restored after it was rebooted using the GUI. Which two options will prevent this situation in the future? (Choose two)

A. Change the Adaptive Mode.
B. Create an HA setup with a second FortiDDoS 200F
C. Move the internet connection from the SFP interfaces to the LC interfaces
D. Replace with a FortiDDoS 1500F

正解：B、D

解説：
B is correct because creating an HA setup with a second FortiDDoS 200F will provide redundancy in case one of the devices fails. This will prevent all traffic from being dropped in the event of a failure.
D is correct because the FortiDDoS 1500F has a larger throughput capacity than the FortiDDoS 200F. This means that it will be less likely to drop traffic even under heavy load.
The other options are incorrect. Option A is incorrect because changing the Adaptive Mode will not prevent the device from dropping traffic. Option C is incorrect because moving the internet connection from the SFP interfaces to the LC interfaces will not change the throughput capacity of the device.

質問 # 28
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. The output is showing a packet descriptor queue accumulated counter
D. Enable HPE shaper for the NP6 will change the output
E. Host-shortcut mode is enabled.

正解：A、C

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).

This is because 802.1X authentication is a mutual process that requires both the client devices and the FortiGate device to support and enable it. The client devices must have 802.1X authentication enabled in their network settings, which allows them to initiate the authentication process when they connect to the hardware switch interface of the FortiGate device. The client devices must also have an 802.1X supplicant software installed, which is a program that runs on the client devices and handles the communication with the FortiGate device using EAP messages. The client devices must also have a trusted certificate installed, which is used to verify the identity of the FortiGate device and establish a secure EAP channel. Therefore, client devices must have 802.1X authentication enabled before assigning an IP address.

Refer to the exhibits.

The exhibits show a FortiMail network topology, Inbound configuration settings, and a Dictionary Profile.
You are required to integrate a third-party's host service (srv.thirdparty.com) into the e-mail processing path.
All inbound e-mails must be processed by FortiMail antispam and antivirus with FortiSandbox integration. If the email is clean, FortiMail must forward it to the third-party service, which will send the email back to FortiMail for final delivery, FortiMail must not scan the e-mail again.
Which three configuration tasks must be performed to meet these requirements? (Choose three.)

A. Create an access receive rule with a Sender value of srv. thirdparcy.com, Recipient value of *@acme.com, and action value of Safe
B. Apply the Catch-AII profile to the ASinbound profile and configure an access delivery rule to deliver to the 100.64.0.72 host.
C. Create an IP policy with a Source value of 100. 64 .0.72/32, enable precedence, and place the policy at the top of the list.
D. Change the scan order in FML-GW to antispam-sandbox-content.
E. Apply the Catch-Ail profile to the CFInbound profile and configure a content action profile to deliver to the srv. thirdparty. com FQDN

正解：C、D、E

解説：
A is correct because the scan order must be changed to antispam-sandbox-content in order for FortiMail to scan the email for spam and viruses before forwarding it to the third-party service.
B is correct because the Catch-All profile must be applied to the CFInbound profile in order for FortiMail to forward clean emails to the third-party service.
E is correct because an IP policy must be created with a Source value of 100.64.0.72/32 in order to allow emails from the third-party service to be delivered to FortiMail.
The other options are not necessary to meet the requirements. Option C is not necessary because the access receive rule will already allow emails from the third-party service to be received by FortiMail. Option D is not necessary because the Catch-All profile already allows emails to be delivered to any destination.
Here are some additional details about integrating a third-party service into the FortiMail email processing path:
The third-party service must be able to receive emails from FortiMail and send them back to FortiMail.
The third-party service must be able to communicate with FortiMail using the SMTP protocol.
The third-party service must be able to authenticate with FortiMail using the SMTP AUTH protocol.
Once the third-party service is integrated into the FortiMail email processing path, all inbound emails will be processed by FortiMail as usual. If the email is clean, FortiMail will forward it to the third-party service. The third-party service will then send the email back to FortiMail for final delivery. FortiMail will not scan the email again.

A remote worker requests access to an SSH server inside the network. You deployed a ZTNA Rule to their FortiClient. You need to follow the security requirements to inspect this traffic.
Which two statements are true regarding the requirements? (Choose two.)

A. SSH traffic is tunneled between the client and the access proxy over HTTPS
B. Traffic is discarded as ZTNA does not support SSH connection rules
C. You need to configure a FortiClient SSL-VPN tunnel to inspect the SSH traffic.
D. FortiGate can perform SSH access proxy host-key validation.

正解：A、D

解説：
ZTNA supports SSH connection rules that allow remote workers to access SSH servers inside the network through an HTTPS tunnel between the client and the access proxy (FortiGate). The access proxy acts as an SSH client to connect to the real SSH server on behalf of the user, and performs host-key validation to verify the identity of the server. The user can use any SSH client that supports HTTPS proxy settings, such as PuTTY or OpenSSH.

質問 # 33
SD-WAN is configured on a FortiGate. You notice that when one of the internet links has high latency the time to resolve names using DNS from FortiGate is very high.
You must ensure that the FortiGate DNS resolution times are as low as possible with the least amount of work.
What should you configure?

A. Configure local out traffic to use the outgoing interface based on SD-WAN rules with the interface IP and configure an SD-WAN rule to the DNS server.
B. Configure an SD-WAN rule to the DNS server and use the FortiGate interface IPs in the source address.
C. Configure local out traffic to use the outgoing interface based on SD-WAN rules with a manual defined IP associated to a loopback interface and configure an SD-WAN rule from the loopback to the DNS server.
D. Configure two DNS servers and use DNS servers recommended by the two internet providers.

正解：A

解説：
SD-WAN is a feature that allows users to optimize network performance and reliability by using multiple WAN links and applying rules based on various criteria, such as latency, jitter, packet loss, etc. One way to ensure that the FortiGate DNS resolution times are as low as possible with the least amount of work is to configure local out traffic to use the outgoing interface based on SD-WAN rules with the interface IP and configure an SD-WAN rule to the DNS server. This means that the FortiGate will use the best WAN link available to send DNS queries to the DNS server according to the SD-WAN rule, and use its own interface IP as the source address. This avoids NAT issues and ensures optimal DNS performance. Reference: https://docs.fortinet.com/document/fortigate/7.0.0/sd-wan/19662/sd-wan

質問 # 34
Refer to the exhibit.

You are deploying a FortiGate 6000F. The device should be directly connected to a switch. In the future, a new hardware module providing higher speed will be installed in the switch, and the connection to the FortiGate must be moved to this higher-speed port.
You must ensure that the initial FortiGate interface connected to the switch does not affect any other port when the new module is installed and the new port speed is defined.
How should the initial connection be made?

A. Connect the switch on any interface between ports 5 to 8.
B. Connect the switch on any interface between ports 21 to 24
C. Connect the switch on any interface between ports 1 to 4
D. Connect the switch on any interface between ports 25 to 28

正解：C

解説：
The FortiGate 6000F has 24 1/10/25-Gbps SFP28 data network interfaces (1 to 24). These interfaces are divided into the following interface groups: 1 to 4, 5 to 8, 9 to 12, 13 to 16, 17 to 20, and 21 to 24. The ports 25 to 28 are 40/100-Gbps QSFP28 data network interfaces.
The initial connection should be made to any interface between ports 1 to 4. This is because the ports 21 to 24 are part of the same interface group, and changing the speed of one of these ports will affect the speeds of all of the ports in the group. The ports 5 to 8 are also part of the same interface group, so they should not be used for the initial connection.
The new hardware module that will be installed in the switch will provide higher speed ports. When this module is installed, the speed of the ports 21 to 24 will be increased. However, this will not affect the ports 1 to 4, because they are not part of the same interface group.
Therefore, the initial connection should be made to any interface between ports 1 to 4, in order to ensure that the FortiGate interface connected to the switch does not affect any other port when the new module is installed and the new port speed is defined.
