When troubleshooting FortiGuard connectivity issues, which action is valid?

Verifying management VDOM internet access is a valid action when troubleshooting FortiGuard connectivity issues. VDOMs, or Virtual Domains, in Fortinet's architecture, can have their own network settings, including internet access configurations. If the management VDOM does not have correct routing or firewall policies to allow outbound traffic to FortiGuard servers, it will result in connectivity problems. Therefore, checking the management VDOM's internet access ensures that the device can successfully reach the necessary FortiGuard services for updates, threat intelligence, and other critical functions.

Addressing this aspect of configuration is crucial because even if the rest of the device functions correctly, lacking internet access in the management VDOM means that FortiGuard services will remain unreachable, leading to troubleshooting complications and security risks due to outdated information.
