Explanation
In an active/active high availability (HA) firewall pair, when a firewall experiences a failure of a monitored path, it enters the "Tentative" state1. This state indicates that the firewall is synchronizing sessions and configurations from its peer due to a failure or a change in monitored objects such as a link or path. The firewall in this state is not fully functional but is working towards resuming normal operations by syncing with its peer. Therefore, the correct answer is B. Tentative.

A template is a set of configuration options that can be applied to one or more firewalls or virtual systems managed by Panorama. A template can include settings from the Device and Network tabs on the firewall web interface, such as login banner, SSL decryption exclusion, and dynamic updates4. These settings can be configured in a template named "Global" and included in all template stacks. A template stack is a group of templates that Panorama pushes to managed firewalls in an ordered hierarchy4. References: Manage Templates and Template Stacks, PCNSE Study Guide (page 50)
