PCNSE Exam Dumps - Palo Alto Networks Certified Security Engineer (PCNSE) PAN-OS 11.0

In Palo Alto Networks firewalls, the processing of NAT rules occurs in a top-down fashion, similar to security policies. To exclude a specific IP address from a broader source NAT rule, a more specific NAT rule must be placed above the broader rule.

C. Place a more specific NAT rule above the broader one:

Create a source NAT rule (NAT-Rule-1) to translate the broader network range (10.0.0.0/23) with dynamic IP and port translation. This rule allows the majority of the subnet to access the internet through NAT.

Create another NAT rule (NAT-Rule-2) with the source IP address in the original packet set specifically to the IP address that should not be translated (10.0.0.10/32). In this rule, set the source translation to none, indicating that this traffic should not be translated and thus not allowed to access the internet.

Place NAT-Rule-2 above NAT-Rule-1 in the NAT policy list. This ensures that the more specific rule (NAT-Rule-2) is evaluated first. If traffic matches NAT-Rule-2, it will not be translated or allowed to the internet, effectively excluding the specific server from internet access.

This configuration leverages the principle of specificity and the order of operation in NAT policies to exclude a specific IP address from source NAT translation, thereby preventing it from accessing the internet.

Be sure to assign both firewalls in an active-passive high availability (HA) configuration to the same device group so that Panorama will push the same policy rules and objects to those firewalls. #############PAN-OS doesn’t synchronize pushed rules across HA peers.######### To manage rules and objects at different administrative levels in your organization, Create a Device Group Hierarchy.

The Device Group and Template Admin role is tailored for managing specific device groups and templates in Panorama, allowing contractors to deploy policies and objects within their assigned scope without broader administrative access. This aligns with compliance by restricting privileges.

Option B (Dynamic Admin) is undefined in PAN-OS; Panorama Admin is too broad. Option C (Read-only Superuser) prevents configuration changes. Option D (Custom Panorama Admin) could work but requires more setup than the predefined role. Documentation recommends this role for such scenarios.

● Ping Interval—Specify the interval between pings that are sent to the destination IP address (range is 200 to 60,000ms; default is 200ms).

● Ping Count—Specify the number of failed pings before declaring a failure (range is 3 to 10; default is 10).

 The correct packet-flow sequence is C. PBF > Static route > Security policy enforcement. This sequence describes the order of operations that the firewall performs when processing a packet. PBF stands for Policy-Based Forwarding, which is a feature that allows the firewall to override the routing table and forward traffic based on the source and destination addresses, application, user, or service. PBF is evaluated before the static route lookup, which is the default method of forwarding traffic based on the destination address and the longest prefix match. Security policy enforcement is the stage where the firewall applies the security policy rules to allow or block traffic based on various criteria, such as zone, address, port, user, application, etc12. References: Policy-Based Forwarding, Packet Flow Sequence in PAN-OS
