Suggested Answer: C

What Is a Watchdog Timeout?

The watchdog is a software or hardware mechanism that monitors the system's health and ensures it is operating correctly.

If the system fails to respond or update the watchdog timer within the specified time, the watchdog triggers a system panic to avoid further corruption or damage.

Cause of Watchdog Timeout:

This usually occurs due to:

A hardware failure (e.g., CPU or memory issue).

A software bug causing a system hang or crash.

The panic ensures the system stops operation to preserve data integrity and aid in troubleshooting.

NetApp Reference Documentation:

'ONTAP Troubleshooting Guide' and 'Core Dump Analysis Guide' provide details on interpreting watchdog timeouts and recommended actions.
