Explanation: 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).
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.

Explanation: 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.

Explanation: 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 belongto 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 PPPoE and may change frequently.

Explanation: 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.

Explanation: 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.

Explanation: The HA heartbeat interval is 100ms, and the number of lost heartbeats before a failover is detected is 2. So, it will take 2 * 100ms = 200ms for a failover to be detected by the secondary cluster member.

Explanation: When using inbound SSL inspection, FortiGate needs to present a certificate to the client that matches the requested domain name. If no matching certificate is found in the server-cert list, FortiGate will fall-back to the default Fortinet_CA_SSL certificate, which is self-signed and may trigger a warning on the client browser.

Explanation: 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.

Explanation: 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. D. 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.

Explanation: The two reasons for the negative impact on the FortiGate HA status and FortiManager status after enabling TPM are:
The private-data-encryption key entered on the primary unit did not match the value that the TPM expected. This could happen if the TPM was previously enabled and then disabled, and the key was changed in between. The TPM will reject the new key and cause an error in the configuration synchronization.
Configuration for TPM is not synchronized between FortiGate HA cluster members. Each cluster member must have the same private-data-encryption key to form a valid HA cluster and synchronize their configurations. However, enabling TPM on one unit does not automatically enable it on the other units, and the key must be manually entered on each unit. To resolve these issues, the administrator should disable TPM on all units, clear the TPM data, and then enable TPM again with the same private-data-encryption key on each unit.

Explanation: 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.

Explanation: The output of the status of high availability on the FortiGate shows that the cluster mode is active-passive, which means that only one FortiGate unit is active at a time, while the other unit is in standby mode. The active unit handles all traffic and also sends HA heartbeat packets to monitor the standby unit. The standby unit becomes active if it stops receiving heartbeat packets from the active unit, or if it receives a higher priority from another cluster unit. In active-passive mode, all cluster units share a virtual MAC address for each interface, which is used as the source MAC address for all packets forwarded by the cluster.
