To prevent the import from affecting ongoing traffic when you import the configuration of an HA pair into Panorama, you should disable config sync on both firewalls. Config sync is a feature that enables the firewalls in an HA pair to synchronize their configurations and maintain consistency. However, when you import the configuration of an HA pair into Panorama, you want to avoid any changes to the firewall configuration until you verify and commit the imported configuration on Panorama. Therefore, you should disable config sync before importing the configuration, and re-enable it after committing the changes on Panorama12. References: Migrate a Firewall HA Pair to Panorama Management, PCNSE Study Guide (page 50)

The vsysadmin role in Palo Alto Networks firewalls is a virtual system (vsys)-specific administrative role with limited privileges. It can commit changes to the candidate configuration of the assigned vsys (Option B) and create/edit Security policies and profiles specific to that vsys (Option C). This role is designed for multi-tenant environments where administrators manage only their assigned virtual systems.

Option A (configure resource limits) is a superuser or device-level task, not within vsysadmin’s scope. Option D (configure interfaces) is also outside vsysadmin’s permissions, as interface management is a device-wide function. Official documentation defines these privileges clearly.
