A company is upgrading its existing Palo Alto Networks firewall from version 7.0.1 to 7.0.4. Which three methods can the firewall administrator use to install PAN-OS 7.0.4 across the enterprise? (Choo

Administrators can manually download the PAN-OS image files from the Palo Alto Networks support portal (support.paloaltonetworks.com) to a local machine and then upload and install them onto individual firewalls using the web interface or CLI. This is a common and flexible method for upgrades.

While USB drives can be used for initial firewall setup or recovery, the firewall does not automatically update PAN-OS from a USB drive in a standard operational upgrade scenario.

Firewalls do not 'push' updates from the support site themselves; rather, updates are either downloaded by the firewall directly, or by an administrator and then installed.

One firewall cannot directly push its PAN-OS update to other firewalls; this type of centralized distribution requires a management platform like Panorama.

A firewall administrator can directly initiate a download and installation of the PAN-OS software update from the Palo Alto Networks update servers through the firewall's web interface or CLI, provided the firewall has internet access and valid licenses. This automates the fetching and installation process for a single device.

For managing multiple firewalls in an enterprise, Panorama, the central management platform, can download PAN-OS images and then push these updates to all or a selection of its managed firewalls. This method provides centralized control and streamlines large-scale deployments.
