Question

By default, EIGRP uses which of the following metrics (2):

A) Load and Bandwidth
B) Bandwidth and Reliability
C) Reliability and Delay
D) Load and Delay

Answer 1

EIGRP by default uses bandwidth and delay as metrics to calculate the best path to a network, making the correct answer D) Bandwidth and Delay.

Step-by-step explanation:

By default, Enhanced Interior Gateway Routing Protocol (EIGRP) uses bandwidth and delay as its composite metric components to calculate the best path to a network. Therefore, the correct answer to the student's question is D) Bandwidth and Delay. EIGRP considers these two parameters since they are the most significant in determining the speed and latency of a route. It is often misconceived that EIGRP uses load or reliability by default; however, these metrics, along with MTU (Maximum Transmission Unit), are part of the extended metric set and are not used unless specifically configured.
