NSE8_812 Online Practice Questions and Answers

Correct Answer: C

Explanation: 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. References:https://docs.fortinet.com/document/fortianalyzer/6.4.0/administration- guide/103664/time-zone-and-daylight-saving-time

Correct Answer: D

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.

Correct Answer: BD

Option B: Adding more web servers to the real server pool will increase the overall capacity of the load balancer, which should help to resolve the issue of users not being able to access the website.

Option D: Adding a connection-pool to the FortiADC virtual server will allow the load balancer to cache connections to the web servers, which can help to improve performance and reduce the number of dropped connections. Option A:

Changing the persistence rule to LB_PERSIS_SSL_SESSJD would only be necessary if the current persistence rule is not working properly. In this case, the CPU usage on the FortiADC and the web servers is low, so the persistence rule is

likely not the issue.

Option C: Disabling SSL between the FortiADC and the web servers would reduce the load on the FortiADC, but it would also make the website less secure. Since the bandwidth utilization is under 30%, it is unlikely that disabling SSL would

resolve the issue. Reference: https://docs.fortinet.com/document/fortiadc/7.2.1/handbook/970956/configuring- virtual-servers

Correct Answer: D

Explanation: 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.

Correct Answer: AE

A is correct because if no client update time is specified on EMS, the user will be able to choose the time of installation if they wish to delay. This is because the FortiClient EMS server will not force the installation on the client. E is correct

because the Windows clients only require "File and Printer Sharing" allowed and the rest is handled by Active Directory group policy. This is because the Active Directory group policy will configure the Windows clients to automatically install

FortiClient and the FortiClient EMS server will only need to push the initial configuration to the clients.

The other options are incorrect. Option B is incorrect because a client can only be eligible for one enabled configuration on the EMS server. Option C is incorrect because you can deploy initial installations to both Windows and macOS clients.

Option D is incorrect because you can use the included SQL Server Express to deploy FortiClient EMS.

Correct Answer: D

Explanation: 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.

Correct Answer: C

Explanation: The firewall policy in the exhibit allows all traffic from the internal network to the cloud. To enforce authentication on this traffic, the administrator needs to add the auth- on-demand option to the policy. This option will force all

users to authenticate before they are allowed to access the cloud.

The following is the correct configuration:

config firewall policy

edit 1

set srcintf "internal"

set dstintf "wan1"

set srcaddr "all"

set dstaddr "all"

set service "all"

set action accept

set auth-on-demand enable

Correct Answer: BE

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). 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.

Correct Answer: B

Explanation: 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.

Correct Answer: DE

Explanation: D. The administrator must first manually map the interface for each device with a meta field.

The Jinja template in the exhibit is expecting a meta field calledWANto be set on the managed FortiGate. This meta field will specify which interface on the FortiGate should be assigned the "WAN" role. If the meta field is not set, then the

template will fail. E. The template will fail because this configuration can only be applied with a CLI or TCL script.

The Jinja template in the exhibit is trying to configure the interface role on the managed FortiGate. This type of configuration can only be applied with a CLI or TCL script. The Jinja template will fail because it is not a valid CLI or TCL script.
