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 policy active
No. Class Type Version Time Created Name 1 applet system 1.0 Mar 1 00:00:12 2025 TRACK-INTERFACE Event Type: syslog (pattern OSPF-5-ADJCHG) Action: cli command 'show ip route'
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
✓
The EEM applet 'TRACK-INTERFACE' is active and will execute 'show ip route' when a syslog message matching 'OSPF-5-ADJCHG' is generated.
The output shows active EEM policies that are currently enabled and waiting for their trigger events. It displays the applet name, class, type, version, creation time, the event that triggers it, and the actions it will execute. This helps verify that an applet is active and what it does.
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 EEM applet 'TRACK-INTERFACE' is active and will execute 'show ip route' when a syslog message matching 'OSPF-5-ADJCHG' is generated.
Why this is correct
Correct. The output shows the applet is active, triggered by syslog pattern OSPF-5-ADJCHG, and will execute the CLI command 'show ip route'.
- ✗
The EEM applet 'TRACK-INTERFACE' is currently executing and has run 'show ip route'.
Why it's wrong here
Incorrect. 'Active' means it is registered and waiting for the trigger, not currently executing.
- ✗
The EEM applet 'TRACK-INTERFACE' has been triggered and the output of 'show ip route' is displayed.
Why it's wrong here
Incorrect. The output shows the policy definition, not the result of execution.
- ✗
The EEM applet 'TRACK-INTERFACE' is inactive and needs to be enabled.
Why it's wrong here
Incorrect. The applet is listed as active, meaning it is enabled.

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.
