A Panorama upgrade can fail if expired certificates (Option D) prevent secure communication with update servers or managed devices. Certificates (e.g., device certificates) must be valid for the upgrade process to proceed.

Option A (GlobalProtect) is unrelated to Panorama upgrades. Option B (outdated plugins) may cause compatibility issues post-upgrade, not install failure. Option C (management-only mode) doesn’t block upgrades. Documentation lists certificate expiration as a common issue.

When an administrator needs to evaluate recent policy changes that were committed and pushed to a firewall device group in Panorama, the most direct approach is to use the "Preview Changes" feature.

A. Click Preview Changes under Push Scope:

The "Preview Changes" option is available under the "Push Scope" in Panorama. This feature allows administrators to see a detailed comparison of the changes that are about to be pushed to the managed firewalls or that have been recently pushed. It highlights the differences between the current configuration and the previous one, making it easier to identify exactly what changes were made, including modifications to policies, objects, and other settings.

This is particularly useful for auditing and verifying that the intended changes match the actual changes being deployed, enhancing transparency and reducing the risk of unintended configuration modifications.

This approach provides a clear and concise way to review configuration changes before and after they are applied, ensuring that policy modifications are intentional and accurately reflect the administrator's objectives.

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.
