Refer to the topology and the provided configurations. Which path does traffic take from R1 to R5?

The correct answer is A. The traffic goes through R2.. EIGRP selects the best path based on its composite metric (primarily bandwidth and delay). When R1 computes the EIGRP metric to reach R5's network, the path through R2 yields a lower (better) composite metric than the path through R3. This is typically due to higher bandwidth or

Explanation

EIGRP selects the best path based on its composite metric (primarily bandwidth and delay). When R1 computes the EIGRP metric to reach R5's network, the path through R2 yields a lower (better) composite metric than the path through R3. This is typically due to higher bandwidth or lower delay on the R1-R2-R5 path as shown in the configuration. EIGRP installs only equal-cost paths by default (unlike IGRP/EIGRP with variance for unequal load balancing). Since only one path has the lowest metric, all traffic follows that single best path through R2. For unequal load balancing to occur (option D), the 'variance' command would need to be configured, and no such configuration is indicated.
