Examice · Accepted Answer

In the exhibit, the costs are labeled on the links between routers. To determine the path R6 will take to reach R1, we need to compare the total costs of each path. If R6 takes the path R6 > R4 > R2 > R1 (Option A), the total cost will be 5 (R6 to R4) + 10 (R4 to R2) + 5 (R2 to R1) = 20. Option D follows the path R6 > R5 > R3 > R2 > R1 with a total cost of 5 (R6 to R5) + 5 (R5 to R3) + 3 (R3 to R2) + 5 (R2 to R1) = 18. Since 18 is less than 20, the path with the lowest cost from R6 to R1 is via R6 > R5 > R3 > R2 > R1, making D the correct answer.
