Refer to the exhibits, which show the system performance output and the default configuration of high memory usage thresholds in a FortiGate.





Based on the system performance output, what can be the two possible outcomes? (Choose two.)

  1. FortiGate will start sending all files to FortiSandbox for inspection.
  2. FortiGate has entered conserve mode.
  3. Administrators cannot change the configuration.
  4. Administrators can access FortiGate onlythrough the console port.

Answer(s): B,D

Explanation:

Based on the system performance output provided, the memory usage on the FortiGate device is at 90%, which is above the green threshold (82%) but below the red threshold (88%). Given this high memory usage, the FortiGate device will enter "conserve mode" to prevent further resource exhaustion. In conserve mode:
B . FortiGate has entered conserve mode: When the memory usage reaches or exceeds certain thresholds (in this case, the green and red thresholds), the FortiGate enters conserve mode to protect itself from running out of memory entirely. This mode limits some functionalities to reduce memory usage and avoid a potential system crash.
D . Administrators can access FortiGate only through the console port: During conserve mode, administrative access might be restricted, and administrators may only be able to connect to the device via the console port. This restriction is in place to ensure that the FortiGate can be managed directly, even under low resource conditions.
The other options are not correct:
A . FortiGate will start sending all files to FortiSandbox for inspection: This is unrelated to memory usage and conserve mode.
C . Administrators cannot change the configuration: While access may be limited, configuration changes can still be made via the console port.

Refer to the exhibits.







The exhibits show a diagram of a FortiGate device connected to the network, as well as the firewall policy and IP pool configuration on the FortiGate device.

Two PCs, PC1 and PC2, are connected behind FortiGate and can access the internet successfully. However, when the administrator adds a third PC to the network (PC3), the PC cannot connect to the internet.

Based on the information shown in the exhibit, which two configuration options can the administrator use to fix the connectivity issue for PC3? (Choose two.)

  1. In the firewall policy configuration, add 10. o. l. 3 as an address object in the source field.
  2. In the IP pool configuration, set endig to 192.2.0.12.
  3. Configure another firewall policy that matches only the address of PC3 as source, and then place the policy on top of the list.
  4. In the IP pool configuration, set cype to overload.

Answer(s): B,D

Explanation:

To resolve the issue of PC3 not being able to access the internet, the administrator needs to adjust the IP pool configuration or the firewall policy. The following two options will fix the connectivity issue:
B . In the IP pool configuration, set the ending IP to 192.2.0.12: The current IP pool range is 192.2.0.10-192.2.0.11, which only provides two IP addresses for network address translation (NAT). To allow PC3 to access the internet, the IP pool should be expanded to include an additional IP address by changing the end of the range to 192.2.0.12. D . In the IP pool configuration, set type to overload: Instead of using a one-to-one NAT, changing the type to overload will allow multiple internal addresses (such as PC1, PC2, and PC3) to share a single external IP address. This will solve the issue without needing additional public IP addresses.
The other options are not suitable:
A . In the firewall policy configuration, add 10.0.1.3 as an address object in the source field: This option is unnecessary since the firewall policy already allows all addresses from the source (LAN port3).
C . Configure another firewall policy that matches only the address of PC3 as the source, and then place the policy on top of the list: This option is redundant and would not resolve the underlying issue with the IP pool configuration.

Which method allows management access to the FortiGate CLI without network connectivity?

  1. SSH console
  2. CLI console widget
  3. Serial console
  4. Telnet console

Answer(s): C

Explanation:

The serial console method allows management access to the FortiGate CLI without relying on network connectivity. This method involves directly connecting a computer to the FortiGate device using a serial cable (such as a DB-9 to RJ-45 cable or USB to RJ-45 cable) and using terminal emulation software to interact with the FortiGate CLI. This method is essential for situations where network-based access methods (such as SSH or Telnet) are not available or feasible.

Refer to the exhibit.



In the network shown in the exhibit, the web client cannot connect to the HTTP web server. The administrator runs the FortiGate built-in sniffer and gets the output shown in the exhibit.

What should the administrator do next, to troubleshoot the problem?

  1. Execute a debug flow.
  2. Capture the traffic using an external sniffer connected to part1.
  3. Execute another sniffer on FortiGate, this time with the filter "hose 10.o.1.10".
  4. Run a sniffer on the web server.

Answer(s): A

Explanation:

The sniffer output shows that packets from the web client are reaching the FortiGate and being forwarded to the web server, but there is no indication that the web server is responding. To troubleshoot this issue, executing a debug flow will help analyze the traffic path and pinpoint where the problem might be occurring, such as a possible issue in firewall policy or route settings that is causing the server not to respond correctly.
