PCNSA Device Management and Services Practice Question
Which of the following is NOT a valid method for upgrading PAN-OS software on a Palo Alto firewall?
⚠ Common exam trap
Many candidates assume FTP is a valid method because it is a common file transfer protocol, but Palo Alto Networks explicitly does not support FTP for PAN-OS upgrades, only HTTP/HTTPS-based downloads.

Correct answer & explanation
✓
Using an FTP server
PAN-OS software upgrades on Palo Alto firewalls are supported via the CLI, the Web GUI, and Panorama. FTP is not a supported method because the firewall's upgrade mechanism relies on HTTP/HTTPS for downloading images from the Palo Alto Networks update server or a local web server; FTP protocol is not implemented in the upgrade process.
