350-401 Practice Question: Consider the following EIGRP configuration:…
Consider the following EIGRP configuration:
router eigrp 100
metric weights 0 1 0 1 0 0
What does this configuration accomplish?
⚠ Common exam trap
Cisco often tests the misconception that the `metric weights` command changes the metric calculation from the default, when in fact the given values exactly match the default K values (1,0,1,0,0).

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
✓
It sets the EIGRP metric to use bandwidth and delay only, which is the default behavior.
The `metric weights` command in EIGRP allows you to modify the K values used in the composite metric calculation. The default K values are K1=1, K2=0, K3=1, K4=0, K5=0, which means only bandwidth (K1) and delay (K3) are used. The configuration `metric weights 0 1 0 1 0 0` explicitly sets K1=1, K2=0, K3=1, K4=0, K5=0, which matches the default behavior. Therefore, option A is correct.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
It sets the EIGRP metric to use bandwidth and delay only, which is the default behavior.
Why this is correct
Correct. The default K values are k1=1, k2=0, k3=1, k4=0, k5=0, so this command explicitly sets them to the default.
- ✗
It disables the use of bandwidth in the metric calculation.
Why it's wrong here
Incorrect. k1 is set to 1, so bandwidth is used.
- ✗
It enables the use of load and reliability in the metric calculation.
Why it's wrong here
Incorrect. k4 and k5 are set to 0, so load and reliability are not used.
- ✗
It changes the metric to use only delay.
Why it's wrong here
Incorrect. Both bandwidth and delay are used because k1 and k3 are set to 1.
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.
