300-410 Practice Question: Runs the following command on Router R1: R1# show…
A network engineer runs the following command on Router R1:
R1# show ip route 10.1.1.0
Routing entry for 10.1.1.0/24 Known via "eigrp 100", distance 170, metric 30720 Redistributing via eigrp 100 Last update from 192.168.1.2 on GigabitEthernet0/0, 00:00:05 ago Routing Descriptor Blocks:
* 192.168.1.2, from 192.168.1.2, 00:00:05 ago, via GigabitEthernet0/0
Route metric is 30720, traffic share count is 1
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 route 10.1.1.0/24 is an EIGRP external route, likely redistributed.
The output shows an EIGRP route with an administrative distance of 170, which is the default distance for EIGRP external routes. This indicates the route was redistributed into EIGRP from another protocol or process. The metric of 30720 is the default for a redistributed connected route.
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 route 10.1.1.0/24 is an EIGRP internal route.
Why it's wrong here
The administrative distance of 170 indicates an external route, not internal. Internal EIGRP routes have a default distance of 90.
- ✓
The route 10.1.1.0/24 is an EIGRP external route, likely redistributed.
Why this is correct
The administrative distance of 170 is the default for EIGRP external routes, confirming redistribution.
- ✗
The route 10.1.1.0/24 is learned via OSPF and redistributed into EIGRP.
Why it's wrong here
The output shows the route is known via EIGRP, not OSPF. The distance is EIGRP external, but the source protocol is not indicated.
- ✗
The administrative distance of 170 is non-default and must have been manually configured.
Why it's wrong here
170 is the default administrative distance for EIGRP external routes, not a manual configuration.
Quick reference
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.
