The SNMP (Simple Network Management Protocol) is a widely used protocol for managing and monitoring network devices. One of its key features is the ability to send messages, called SNMP messages, between network devices and a central management system known as the SNMP manager.
The question asks which SNMP message alerts the manager to a condition on the network. Let's examine the answer options:
A. Response: The SNMP response message is sent by a network device in response to an SNMP query message received from the manager. It contains the requested information or the status of the operation. It is not used to alert the manager to a condition on the network.
B. Get: The SNMP get message is sent by the manager to a network device to request information about its current state or configuration. It is not used to alert the manager to a condition on the network.
C. Trap: The correct answer is C. The SNMP trap message is used by network devices to proactively notify the SNMP manager about a specific event or condition that has occurred on the network. When a device detects a condition, such as an interface going down, high CPU utilization, or a critical error, it generates an SNMP trap message and sends it to the manager. The trap message contains information about the event, including the device, the specific condition, and a timestamp. This allows the manager to take appropriate actions or raise alarms based on the received traps.
D. Capture: There is no SNMP message called "capture." It is an invalid option in this context.
In conclusion, the correct answer is C. The SNMP trap message alerts the manager to a condition on the network by proactively notifying it about events or conditions that require attention or action.
