Network Security Administrator PCNSA Updated Exam

The policy set that should be used to ensure that a policy is applied just before the default security rules is the shared post-rulebase. The shared post-rulebase is a set of Security policy rules that are defined on Panorama and apply to all firewalls or device groups. The shared post-rulebase is evaluated after the local firewall policy and the child device-group post-rulebase, but before the default security rules. The shared post-rulebase can be used to enforce common security policies across multiple firewalls or device groups, such as blocking high-risk applications or traffic1. References: Security Policy Rule Hierarchy, Security Policy Rulebase, Certifications - Palo Alto Networks, Palo Alto Networks Certified Network Security Administrator (PAN-OS 10.0) or [Palo Alto Networks Certified Network Security Administrator (PAN-OS 10.0)].

When a security rule is configured as Intrazone, the destination zone field cannot be changed. This is because an intrazone rule applies to traffic that originates and terminates in the same zone. The destination zone is automatically set to the same value as the source zone and cannot be modified1. An intrazone rule allows you to control and inspect traffic within a zone, such as applying security profiles or logging options2. References: What are Universal, Intrazone and Interzone Rules?, Security Policy, Updated Certifications for PAN-OS 10.1, Palo Alto Networks Certified Network Security Administrator (PAN-OS 10.0) or [Palo Alto Networks Certified Network Security Administrator (PAN-OS 10.0)].
