Which two factors affect the calculation of EIGRP metrics when all possible default values are used?

The calculation of EIGRP (Enhanced Interior Gateway Routing Protocol) metrics relies primarily on two key factors: bandwidth and delay. Bandwidth refers to the maximum data transfer rate of a network connection, while delay represents the time it takes for packets to traverse the network.

When EIGRP computes the best path to a destination, it uses these two metrics among others to arrive at a composite metric that determines the most efficient route. By default, EIGRP considers the bandwidth of the slowest link in the path and the cumulative delay of all links to provide a comprehensive evaluation of route quality.

The reason the other options do not affect the default EIGRP metric calculation is that they either relate to different contexts within networking or are not included in the default metric calculation. For instance, latency typically encompasses various delay elements but is not directly measured in the same manner as EIGRP's default delay metric. Reliability pertains to the quality of the link but isn't inherently factored into default EIGRP calculations. Load and capacity are also not the primary considerations for the default metric. In summary, bandwidth and delay are foundational to understanding EIGRP's decision-making process regarding routing metrics.
