Server Utilization Spikes and SNMPv3 Monitoring

A technician is utilizing SNMPv3 to monitor network statistics.

Which of the following actions would occur immediately of a server's utilization spikes above the prescribed value?

A.

A trap message is sent via UDP to the monitoring workstation.

B.

The SET function pushes an alert to the MIB database.

C.

The object identifier is modified and reported during the next monitoring cycle.

D.

A response message is sent from the agent to the manager.

A.

SNMP (Simple Network Management Protocol) is a protocol that is commonly used for network management and monitoring. SNMPv3 is a version of SNMP that provides security features such as authentication and encryption.

When a server's utilization spikes above the prescribed value in an SNMPv3 environment, the SNMP agent on the server will send a trap message to the SNMP manager (monitoring workstation). The trap message is sent via UDP (User Datagram Protocol), which is a connectionless protocol that does not guarantee reliable delivery of packets.

Option A is therefore the correct answer to this question: "A trap message is sent via UDP to the monitoring workstation."

Option B, "The SET function pushes an alert to the MIB database," is incorrect. The SET function is used to set the value of a variable in the Management Information Base (MIB) database, not to send alerts.

Option C, "The object identifier is modified and reported during the next monitoring cycle," is also incorrect. Object identifiers (OIDs) are used to uniquely identify managed objects in the MIB database, but they are not modified when server utilization spikes.

Option D, "A response message is sent from the agent to the manager," is also incorrect. A response message is sent from the agent to the manager only in response to a request message from the manager, not when server utilization spikes.
