Question

Quizplus · Accepted Answer

A watchdog processor is designed to monitor a system's activity and detect any fault or error that may occur. In the event of a fault or error, the watchdog processor takes corrective action to ensure that the system operates as intended. This is an example of fault tolerance at the network communications level as it ensures that network communications are uninterrupted even in the event of a fault or error. Disk mirroring, rollback processing, and uninterruptable power supply are not specifically designed for fault tolerance at the network communications level.
