The best decryption best practice that the administrator should consider is A: Consider the local, legal, and regulatory implications and how they affect which traffic can be decrypted. This is because decryption involves intercepting and inspecting encrypted traffic, which may raise privacy and compliance issues depending on the jurisdiction and the type of traffic1. Therefore, the administrator should be aware of the local, legal, and regulatory implications and how they affect which traffic can be decrypted, and follow the appropriate guidelines and policies to ensure that decryption is done in a lawful and ethical manner1.

To create Security rules in Panorama that reference specific users and groups from Active Directory (AD), the Panorama-managed firewalls need access to user-to-group mapping information. This is achieved through Group Mapping, which relies on User-ID functionality. In a Panorama-managed environment, a "master device" must be designated within the device group to provide this Group Mapping data. The master device is a firewall that retrieves user and group information from AD (via LDAP or User-ID agent) and shares it with other firewalls in the device group. This ensures consistent user-based policies across all devices in the group.

The CLI command "show system state filter-pretty sys.sl.p8.phy" is used to display detailed physical layer information, which would include the physical media connected to a specific interface such as ethernet1/8. This command is designed to filter the output to show relevant physical layer information for the specified interface.For more information on Palo Alto Networks CLI commands and their outputs, refer to the "PAN-OS® CLI Reference Guide".

To create an application-based Security policy rule to allow Evernote, the administrator only needs to add the Evernote application to the Security policy rule. The Evernote application is a predefined App-ID that identifies the traffic generated by the Evernote client or web interface. The Evernote application implicitly uses SSL and web browsing as dependencies, which means that the firewall automatically allows these applications when the Evernote application is allowed. Therefore, there is no need to add HTTP, SSL, or web browsing applications to the same Security policy rule. Adding these applications would broaden the scope of the rule and potentially allow unwanted traffic12. References: App-ID Overview, Create a Security Policy Rule

When administrative functions (licensing, updates) use a data plane interface, the firewall requires outbound connectivity to Palo Alto Networks servers (e.g., updates.paloaltonetworks.com) via that interface. If HTTPS/SSH work but licensing/updates fail, the issue is likely upstream blocking or misrouting. Validating upstream devices (Option B) ensures ports (e.g., 443) and destinations are accessible, resolving the issue.

For the transparent proxy method, the request contains the destination IP address of the web server and the proxy transparently intercepts the client request (either by being in-line or by traffic steering). There is no client configuration and Panorama is optional. Transparent proxy requires a loopback interface, User-ID configuration in the proxy zone, and specific Destination NAT (DNAT) rules. Transparent proxy does not support X-Authenticated Users (XAU) or Web Cache Communications Protocol (WCCP). https://docs.paloaltonetworks.com/pan-os/11-0/pan-os-new-features/networking-features/web-proxy
