300-410 Practice Question: Runs the following command to troubleshoot an EEM…
A network engineer runs the following command to troubleshoot an EEM issue:
R1# show event manager history events
Event History: Event Type : syslog Time : Mar 1 00:05:23 Pattern : OSPF-5-ADJCHG Trigger count : 1
Event Type : timer Time : Mar 1 00:06:00 Timer Type : absolute Timer Name : MY-TIMER Trigger count : 1
What does this output indicate?
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
✓
Two events have triggered EEM applets: a syslog event matching 'OSPF-5-ADJCHG' and an absolute timer named 'MY-TIMER'.
The output shows the event history for EEM. It lists events that have triggered EEM applets. Each entry shows the event type (syslog, timer, etc.), the time it occurred, specific details (pattern for syslog, timer type and name for timer), and the number of times that event triggered an applet. This helps in troubleshooting which events are being matched.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Two events have triggered EEM applets: a syslog event matching 'OSPF-5-ADJCHG' and an absolute timer named 'MY-TIMER'.
Why this is correct
Correct. The output shows two events: one syslog event with pattern OSPF-5-ADJCHG triggered once, and one absolute timer named MY-TIMER triggered once.
- ✗
Two EEM applets are currently registered: one for syslog and one for timer.
Why it's wrong here
Incorrect. This command shows event history, not registered applets.
- ✗
The OSPF-5-ADJCHG syslog event triggered an applet that executed a timer.
Why it's wrong here
Incorrect. The events are separate; there is no indication that one triggered the other.
- ✗
The timer event is a countdown timer that triggered after 5 minutes and 23 seconds.
Why it's wrong here
Incorrect. The timer type is 'absolute', which triggers at a specific time, not a countdown. The time shown is when it triggered.

Routing Protocol Comparison
| Protocol | Metric | Max Hops | Algorithm | Type |
|---|---|---|---|---|
| RIP v2 | Hop count | 15 | Bellman-Ford | Distance vector |
| OSPF | Cost (bandwidth) | Unlimited | Dijkstra (SPF) | Link state |
| EIGRP | Composite metric | Unlimited | DUAL | Hybrid |
| IS-IS | Cost | Unlimited | Dijkstra | Link state |
| BGP | Policy / attributes | Unlimited | Path vector | Path vector |
RIP's 15-hop limit makes it unsuitable for large networks. OSPF and EIGRP dominate modern enterprise deployments.
