A support method which will automatically notify the support vendor of a problem would be an example of which of the following monitoring types?

Call home functionality is a proactive support feature commonly found in enterprise hardware like storage arrays and servers. When a critical event or failure is detected by the device, it automatically establishes a secure connection to the vendor's support infrastructure to report the issue, often creating a support ticket without human intervention.

fcping is a diagnostic utility used to test connectivity in Fibre Channel networks, not an automatic notification system.

NPIV (N_Port ID Virtualization) is a Fibre Channel feature for virtualization, allowing multiple virtual ports to share a physical one, not a monitoring or notification type.

SMI-S (Storage Management Initiative-Specification) is a standard for managing heterogeneous storage systems, not a specific monitoring type that automatically notifies vendors.
