The answer is that the configuration `metric weights 0 1 0 1 0 0` explicitly sets the EIGRP metric to use only bandwidth and delay, which is the default behavior. This command modifies the K values in the composite metric formula, and the default K values are K1=1, K2=0, K3=1, K4=0, K5=0, meaning only bandwidth (K1) and delay (K3) are factored in. On the ENCOR 350-401 exam, this tests your understanding of the EIGRP metric weights command default and how to interpret the five numbers in the command syntax. A common trap is assuming that any explicit `metric weights` statement changes the default, but this particular sequence simply reaffirms it. Remember that the default EIGRP metric calculation ignores load and reliability, focusing solely on bandwidth and delay for path selection. A helpful memory tip: the default K values are 1-0-1-0-0, which you can recall as “one bandwidth, zero load, one delay, zero reliability, zero MTU.”
350-401 EIGRP Practice Question
This 350-401 practice question tests your understanding of eigrp. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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.

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.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
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.
Common exam traps
Common exam trap: answer the scenario, not the keyword
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).
Detailed technical explanation
How to think about this question
The EIGRP composite metric formula is: metric = [K1 * bandwidth + (K2 * bandwidth) / (256 - load) + K3 * delay] * [K5 / (reliability + K4)]. With default K values (1,0,1,0,0), the formula simplifies to bandwidth + delay. The `metric weights` command must be configured identically on all routers in the EIGRP domain to prevent neighbor adjacency issues. A real-world scenario where this matters is when an administrator mistakenly changes K values, causing routing loops or suboptimal path selection.

Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the 350-401 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
