Paloalto Networks Updated PCNSE Exam Questions and Answers by sasha

When planning an upgrade in an environment that includes Panorama, firewalls, and log collectors, it's crucial to follow the recommended sequence to ensure compatibility and minimize disruptions. Palo Alto Networks recommends the following order:

Upgrade Panorama: Start with Panorama because it's the central management platform. Upgrading Panorama first ensures that it's compatible with the new PAN-OS versions that the managed devices (firewalls and log collectors) will be upgraded to. Panorama must be able to support the new versions for it to manage and monitor the devices effectively.

Upgrade the log collectors: Next, upgrade the log collectors. Since log collectors work closely with Panorama to aggregate and store logs from the firewalls, they should be upgraded after Panorama to ensure compatibility. Upgrading the log collectors ensures they can handle the log formats and features introduced in the new PAN-OS version.

Upgrade the firewalls: Finally, upgrade the firewalls. The firewalls are the last components to be upgraded to ensure that they remain compatible with the management and log collection infrastructure. Upgrading the firewalls last minimizes the risk of compatibility issues with Panorama and log collectors.

This sequence ensures that all components are compatible and that the management and logging infrastructure can fully support the firewalls running the latest PAN-OS version.

For HIP match logs to be visible on the data center firewall, the following conditions must be met:

HIP profiles added to security rules: HIP profiles must be applied to security rules on the data center firewall to enforce access restrictions based on the received HIP reports. If the HIP profiles are not associated with the security rules, the firewall will not evaluate traffic against these profiles, and consequently, no HIP match logs will be generated.

User-ID enabled on the incoming zone: User-ID must be enabled on the zone where the users are located in the data center firewall. The User-ID feature is responsible for mapping IP addresses to user names, which is critical for applying policies based on user identity and, by extension, for HIP-based policy enforcement.

The other options (A and D) are related to logging and log forwarding but would not directly impact the generation or visibility of HIP match logs on the data center firewall itself.

Each WildFire cloud—global (U.S.), regional, and private—analyzes samples and generates WildFire verdicts independently of the other WildFire clouds. With the exception of WildFire private cloud verdicts, WildFire verdicts are shared globally, enabling WildFire users to access a worldwide database of threat data. https://docs.paloaltonetworks.com/wildfire/10-1/wildfire-admin/wildfire-overview/wildfire-concepts/verdicts.html
