Which of the following features can automatically facilitate a vendor service call in the event of a SAN component failure?

Predictive trending analyzes historical data to forecast potential future issues, but it does not automatically initiate a vendor service call upon an active failure.

An SMS alert to an administrator notifies a human, who then must manually initiate a service call; it does not directly facilitate an automatic vendor service call.

'Call Home' automatically detects hardware failures or critical events in a SAN component and proactively sends a notification directly to the vendor's support organization, often opening a service ticket without manual intervention.

SNMP (Simple Network Management Protocol) is used for monitoring and managing network devices, and while it can send alerts, it typically notifies an NMS or administrator, not directly the vendor for an automatic service call.
