Question 1
At Proseware, the NOC is replacing manual device checks with one monitoring platform. Which option best provides centralized polling and collection from device agents? Choose ONE.
- SNMP manager
- MIB object identifier (OID)
- SNMP SET operation
- SNMP inform
Correct Answer: A
Correct Answer
Answer A is correct because SNMP manager is the right selection because An SNMP manager is the management system that polls agents and receives notifications from managed devices. For SNMP manager, the scenario key outcome is centralized polling and collection from device agents.
Incorrect Answers
Answer B is incorrect because A MIB organizes managed objects, while an OID uniquely identifies a specific managed variable within that hierarchy MIB object identifier misses the SNMP manager decision in this configuration scenario. Operationally, SNMP manager needs another behavior than MIB object identifier provides in this configuration case.
Answer C is incorrect because SNMP SET is a manager-initiated operation that writes a value to a writable managed object For SNMP manager, the configuration evidence requires another function than SNMP SET operation. For SNMP SET operation, separation from SNMP manager remains material in this configuration scenario.
Answer D is incorrect because An SNMP inform is an unsolicited notification that expects acknowledgment from the receiving manager The configuration evidence favors SNMP manager; SNMP inform operates at another control point. Using SNMP inform here would leave the SNMP manager requirement unresolved during this configuration task.
Question 2
At Alpine, a new access switch must publish interface and CPU data to the NMS. Which option best provides device-side access to counters and state for a monitoring system? Choose ONE.
- SNMP GET operation
- SNMP agent
- SNMP trap

Correct Answer: B
Correct Answer
Answer B is correct because SNMP agent is the right selection because An SNMP agent runs on the managed device and exposes local management data to an SNMP manager. For SNMP agent, the scenario key outcome is device-side access to counters and state for a monitoring system.
Incorrect Answers
Answer A is incorrect because SNMP GET is a manager-initiated request that reads the value of a managed object from an agent For SNMP agent, the configuration evidence requires another function than SNMP GET operation. For SNMP GET operation, separation from SNMP agent remains material in this configuration scenario.
Answer C is incorrect because An SNMP trap is an unsolicited notification from an agent to a manager and does not require an acknowledgment The configuration evidence favors SNMP agent; SNMP trap operates at another control point.
Answer D is incorrect because SNMPv3 can provide authenticated and encrypted management exchanges instead of relying only on a clear-text community string The required SNMP agent outcome differs from the SNMPv3 with authentication purpose in this configuration case.
