Suggested answer: B

Explanation:

Palo Alto Networks recommends following a specific upgrade path when upgrading PAN-OS to ensure compatibility and minimize the risk of issues. The recommended path involves sequential upgrades through major releases.

B) The detailed upgrade path from PAN-OS 10.1 to 11.0.x involves:

First, upgrading to the latest preferred maintenance release of the current PAN-OS version (10.1) to ensure that all the latest fixes and improvements are applied.

Next, upgrading to the base version of the next major release (PAN-OS 10.2.0), followed by upgrading to the latest preferred maintenance release of PAN-OS 10.2. This step ensures that the firewall is on a stable and supported version before proceeding to the next major release.

Finally, upgrading to the base version of PAN-OS 11.0 (11.0.0), followed by the desired PAN-OS 11.0.x version. This step completes the upgrade to the new major version, providing access to new features and improvements, such as TLSv1.3 support for management access.

This sequential upgrade path is designed to ensure a smooth transition between major versions, maintaining system stability and security.
