According to the Palo Alto Networks documentation1, the command show system state filter displays the current state of the system and allows you to filter the output by a specific keyword. The keyword ethernet1/1 matches the interface name that the administrator wants to troubleshoot. The output of this command will show information about the transceiver type, tx-power, rx-power, vendor name, and part number for that interface2. Therefore, the correct answer is D.

Logging is a function that is handled by the management plane (control plane) of a Palo Alto Networks firewall. The management plane is responsible for managing and configuring the firewall, as well as generating and storing logs and reports. The management plane communicates with the data plane (also known as the packet forwarding plane) through an internal backplane interface. Signature matching for content inspection, IPSec tunnel standup, and Quality of Service are functions that are handled by the data plane of a Palo Alto Networks firewall. The data plane is responsible for processing and forwarding packets, as well as applying security policies and features to the traffic. The data plane consists of multiple dedicated hardware components, such as the Single-Pass Parallel Processing (SP3) engine, the Security Processing Unit (SPU), and the Network Processing Unit (NPU).

https://docs.paloaltonetworks.com/panorama/10-2/panorama-admin/administer-panorama/enable-automated-commit-recovery The Automated Commit Recovery feature enables the firewall to automatically revert to a previous configuration if a commit operation causes connectivity loss between the firewall and Panorama. The feature performs a connectivity check between the firewall and Panorama after every configuration commit on the firewall. If the check fails, the firewall reverts to the last known good configuration and restores connectivity with Panorama. The feature does not restore the running configuration on a firewall or Panorama if the last commit fails, as this would require manual intervention. The feature does not revert the configuration changes on Panorama, as Panorama is not affected by the commit operation on the firewall. Reference:

Because GlobalProtect users must authenticate to gain access to the network, the IP address-to-username mapping is explicitly known. This is the best solution in sensitive environments where you must be certain of who a user is in order to allow access to an application or service. https://docs.paloaltonetworks.com/pan-os/10-1/pan-os-admin/user-id/user-id-concepts/user-mapping/globalprotect.html
