Final answer:
The correct option is Alarm. An alarm is a notification that an unusual condition exists and should be investigated. So, option C is correct.
Step-by-step explanation:
An Alarm is a notification signifying that an unusual condition exists and should be investigated. It is essential in network monitoring to indicate potential issues that require attention or intervention. When a system encounters an anomaly that could potentially lead to a more serious problem, it triggers an alarm. This is designed to alert the system administrators or users that there is something that requires their attention and possible intervention.
Alarms are common in network monitoring systems, where they can indicate issues such as equipment failure, high usage, or security breaches. In contrast, alerts are also notifications but can be less urgent, trends indicate progressive changes over time, and traps are messages sent by devices to signal specific events or errors. These are typically triggered when predefined thresholds or criteria are met, indicating a potential issue or deviation from normal operation. Responding to alarms promptly is crucial for maintaining the security, stability, and performance of systems and networks, allowing administrators to investigate and address potential problems before they escalate
