300-410 Embedded Event Manager (EEM) Practice Question

This 300-410 practice question tests your understanding of embedded event manager (eem). Examine the command output carefully: the correct answer depends on what the output actually shows, not on general recall alone. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.

A network engineer runs the following command on Router R1:

R1# show event manager policy registered

No. Type Time Created Name 1 applet 00:01:23 UTC Mar 1 2025 BGP_Neighbor_Down

R1# show bgp summary

BGP router identifier 10.0.0.1, local AS number 65001 BGP table version is 1, main routing table version 1

Neighbor        V           AS MsgRcvd MsgSent   TblVer  InQ OutQ Up/Down  State/PfxRcd
192.168.1.2     4        65002       5       5        1    0    0 00:02:00 Established

Based on this output, which statement is correct?

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

The BGP neighbor is up and the EEM policy has not been triggered.

The EEM policy BGP_Neighbor_Down is registered, but the BGP neighbor is in Established state. The correct answer is that the BGP neighbor is up and the EEM policy has not been triggered.

Key principle: OSPF neighbour adjacency depends on matching area, hello/dead timers, network type, and authentication — IP reachability alone is not enough.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • The BGP neighbor is down.

    Why it's wrong here

    The state is Established, indicating it is up.

  • The EEM policy has been triggered.

    Why it's wrong here

    No event history is shown, and the neighbor is up.

  • The BGP neighbor is up and the EEM policy has not been triggered.

    Why this is correct

    The Established state confirms the neighbor is up, so the down event has not occurred.

    Related concept

    OSPF neighbours must agree on key parameters.

  • The EEM policy is disabled.

    Why it's wrong here

    The policy is registered, so it is active.

Common exam traps

Common exam trap: OSPF can fail even when IP connectivity looks correct

OSPF neighbour formation depends on matching areas, timers, network type, authentication and passive-interface behaviour. Do not choose an answer only because the devices can ping.

Trap categories for this question

  • Command / output trap

    No event history is shown, and the neighbor is up.

Detailed technical explanation

How to think about this question

OSPF questions usually test the details that control adjacency and route selection. Read the neighbour state, area, router ID and interface configuration before deciding what is wrong.

KKey Concepts to Remember

  • OSPF neighbours must agree on key parameters.
  • Router ID selection can affect neighbour relationships and LSDB output.
  • OSPF cost influences the preferred path.
  • A route can appear in OSPF information but not become the installed route.

TExam Day Tips

  • Check area mismatch first when OSPF adjacency fails.
  • Review passive interfaces when a network is advertised but no neighbour forms.
  • Use show ip ospf neighbor and show ip route clues carefully.

Key takeaway

OSPF neighbour adjacency depends on matching area, hello/dead timers, network type, and authentication — IP reachability alone is not enough.

Real-world example

How this comes up in practice

A network engineer at a university connects two campus buildings via a fibre link. Both routers run OSPF, but no adjacency forms — even though both routers can ping each other. The engineer finds one router is in area 0 and the other in area 1. OSPF adjacency requires matching area numbers, hello/dead timers, and network type. IP reachability alone is not enough.

What to study next

Got this wrong? Here's your next step.

Review OSPF neighbour requirements — matching area type, hello and dead timers, network type, stub flags, and authentication. Study show ip ospf neighbor states (INIT, 2-WAY, FULL). Then practise related 300-410 OSPF questions on adjacency and route selection.
