Paloalto Networks PCNSE Dumps Questions Answers

Traffic view in the Monitor tab of the firewall GUI can display the information about the NAT policy that is in use for a traffic flow, if the Source or Destination NAT columns are included and reviewed in the detailed log view1. The Source NAT column shows the translated source IP address and port, and the Destination NAT column shows the translated destination IP address and port2. These columns can help the administrator identify which NAT policy is applied to the traffic flow based on the pre-NAT and post-NAT addresses and ports.

The CLI command "show system state filter-pretty sys.sl.p8.phy" is used to display detailed physical layer information, which would include the physical media connected to a specific interface such as ethernet1/8. This command is designed to filter the output to show relevant physical layer information for the specified interface.For more information on Palo Alto Networks CLI commands and their outputs, refer to the "PAN-OS® CLI Reference Guide".

If an administrator wants to apply QoS to traffic based on source, they must specify the post-NAT source address in a QoS policy rule. This is because QoS is enforced on traffic as it egresses the firewall, and the firewall applies NAT rules before QoS rules. Therefore, the firewall will match the QoS policy rule based on the translated source address, not the original source address. If the administrator uses the pre-NAT source address in the QoS policy rule, the firewall will not be able to identify the traffic correctly and apply the desired QoS treatment. References:
