Step-by-step explanation:
The correct answer to the question: Which PAN-OS GUI tab displays widgets and shows general information about the device? is 1) Dashboard. The Dashboard is the main area in the Palo Alto Networks firewall's graphical user interface (GUI) that provides a high-level overview of the system's status and metrics. It displays a collection of widgets that summarize the performance, traffic, and security of the network.
The Dashboard typically includes information such as current sessions, system resources, traffic patterns, and other important system messages that may need attention. In contrast, the Monitor tab is used for logging and reporting features, the Objects tab manages addresses, services, and security profiles, and the Policies tab is where access control, security, and NAT policies are configured.
