CEVAP:

A network system should ensure that all of its components work properly. In the case of a fault, the system should be able to detect, isolate, resolve and log the event.

When a fault occurs, the following steps should be implemented:

• Identify the component of the network that causes the failure.
• Isolate the rest of the network to continue functioning without any interruption.
• Resolve the problem which is the cause of the fault and restore the network to its initial state.
• Log the reason and solution of the fault.
