An administrator wants to upgrade a firewall from PAN-OSֲ® 9.1 to PAN-OSֲ® 10.0. The firewall is not a part of an HA pair.
What needs to be updated first?

Answer options

Correct answer: A

Explanation

Updating the Applications and Threats is crucial before upgrading the PAN-OS to ensure that the firewall has the latest security signatures and threat prevention capabilities. The XML Agent, WildFire, and PAN-OS Upgrade Agent are important components, but they should be updated after ensuring the Applications and Threats are current to maintain optimal security during the upgrade process.
