Palo Alto Networks PCNSE Exam Practice Questions (P. 3)

GPT-4o - Answer

The benefits of nested device groups in Panorama, specifically points A and C, involve significant efficiency in security management. Utilizing nested device group structures allows for the reusing of security policy rules and objects across multiple firewalls, significantly reducing administrative overhead and enhancing consistency. Additionally, all device groups inheriting settings from the shared group streamline processes and ensure uniform policy enforcement, making management scalable and less error-prone. This structure supports a centralized yet customizable control over policies and objects, crucial in larger or more complex network environments.

The correct choice, A, using Virtual Wire interfaces, adequately addresses the requirement due to the limitations in protocol support by Palo Alto Networks devices. Virtual Wire interfaces function in a transparent manner, allowing existing configurations like EIGRP—which is Cisco proprietary and not natively supported on Palo Alto Networks—to continue operating without hindrance. This setup ensures that EIGRP routes between the Core and DMZ are maintained without requiring direct integration of the routing protocol into the Palo Alto Networks environment.

The selection of "web-browsing" as the application and a custom service with TCP port 8080 is correct for enabling cleartext (HTTP) web browsing traffic to a server set on this non-standard port. This setup directly addresses the requirement of targeting HTTP traffic specifically on port 8080, where typical configurations, such as application-default for web-browsing, would not suffice since it covers only the well-known HTTP port 80. By creating a custom service to specify the exact port, we ensure that the policy properly aligns with the server’s listening configuration and the security needs.

RADIUS is the method to utilize when integrating any MFA platforms that are not natively supported by PAN-OS. It acts as a universal solution to link with various third-party MFA providers, which is not possible through direct integrations like Okta, DUO, or PingID that only support specific platforms. This capability of RADIUS to offer extensive compatibility makes it essential for a flexible and inclusive network security environment.
