350-401 Question #108: Real Exam Question with Answer & Explanation

Question

What does this EEM applet event accomplish? "event snmp oid 1.3.6.1.3.7.1.5.1.2.4.2.9 get-type next entry-op g entry-val 75 poll-interval 5"

Options

• AIt issues email when the value is greater than 75% for five polling cycles.
• BIt reads an SNMP variable, and when the value exceeds 75%, it triggers an action.
• CIt presents a SNMP variable that can be interrogated.
• DUpon the value reaching 75%, a SNMP event is generated and sent to the trap server.

Explanation

EEM SNMP Event Applet Explanation

Option B is correct because this EEM applet event uses the event snmp detector to read (poll) an SNMP OID, and when the retrieved value is greater than (entry-op g) the entry value of 75 (entry-val 75), it triggers the configured EEM actions - this is purely a monitoring/triggering mechanism, not an action itself.

• Option A is wrong because the applet doesn't inherently send email - that's an action statement, not an event statement. Also, the poll-interval 5 means polling every 5 seconds, not "five polling cycles."
• Option C is wrong because EEM doesn't present or expose SNMP variables for external interrogation; it reads them internally to make decisions.
• Option D is wrong because EEM does not generate SNMP traps to a trap server - it triggers internal EEM actions; sending a trap would require a separate action snmp-trap command.

Memory Tip: Think of the EEM SNMP event as a smoke detector - it continuously reads the environment (polls the OID every poll-interval seconds), and when a threshold is crossed (entry-op g entry-val 75), it triggers an alarm (the action). The event statement only detects, never acts.
