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

  The EIGRP metric weights command modifies the K values used in the composite metric calculation. By default, K1 and K3 are set to 1 while K2, K4, and K5 are set to 0, which means only bandwidth and delay are considered. This command explicitly configures those default values, so it does not alter the metric behavior from the standard EIGRP operation.

• ✗

  It disables the use of bandwidth in the metric calculation.

  Why it's wrong here

  This interpretation is incorrect because the command sets K1 to 1, not 0. Bandwidth remains a key factor in the composite metric calculation through the formula 256*(K1*Bandwidth + K3*Delay). To truly disable bandwidth from the metric, K1 would need to be set to 0, which is not the case here.

• ✗

  It enables the use of load and reliability in the metric calculation.

  Why it's wrong here

  Load and reliability are not enabled by this command because their associated K values remain at zero. The default K values are K1=1, K2=0, K3=1, K4=0, K5=0, and this command preserves them. Load corresponds to K2, and reliability corresponds to K4 or K5; with those set to 0, the metric calculation ignores link load and reliability, keeping the standard default behavior.

• ✗

  It changes the metric to use only delay.

  Why it's wrong here

  If the metric were to use only delay, K1 would need to be 0 while K3 remained 1. However, this command sets both K1 and K3 to 1, so bandwidth and delay are combined in the metric. The composite metric therefore still includes bandwidth as half of its default calculation, contradicting the idea that delay is the sole factor.
