Objective 3.2

N10-009

Given a scenario, use network monitoring technologies.

Objective 3.2 sits in Network Operations, which carries 19% of the Network+ exam. The questions below are original, written from the official objective title above, and each explanation cites the CompTIA page it rests on.

3-2Network Operations

Which SNMP PDU type does an agent use to notify a network management station about a significant event without waiting for a poll from that station?

Trap-PDU, which an agent sends to report an event to the managerCorrect · your answerCorrect. Trap-PDU is the unsolicited notification an agent sends to report an event to the manager.
SetRequest-PDU, which a manager sends to change an object valueSetRequest-PDU is initiated by the manager to alter a value on the agent, the opposite direction of communication described here.
GetResponse-PDU, which an agent sends back to answer a pollGetResponse-PDU is the agent's reply to a Get or Set request, meaning it is solicited rather than unsolicited.
GetRequest-PDU, which a manager sends to poll an object valueGetRequest-PDU is initiated by the manager to poll a value, not sent by the agent to report an event.

Correct.

Checked against datatracker.ietf.org, July 2026

Concept

RFC 1157 defines five PDU types for SNMP exchanges, and the Trap-PDU is the only one that is unsolicited, sent by the agent rather than requested by the manager.

Why A

The Trap-PDU exists specifically so an agent can report events such as interface changes or restarts to the management station on its own initiative, matching the scenario described.
