Refer to the exhibit:
Assume that the routing protocol referenced in each choice below is configured with its default settings and the given routing protocol is running on all the routers. Which two conditional statements accurately state the path that will be chosen between networks 10.1.0.0 and 10.3.2.0 for the routing protocol mentioned? (Choose two.)
A.
If OSPF is the routing protocol, the path will be from R1 to R3 to R4 to R5.
B.
If OSPF is the routing protocol, the path will be from R1 to R2 to R5.
C.
If OSPF is the routing protocol, the path will be from R1 to R5.
D.
If RIPv2 is the routing protocol, the path will be from R1 to R3 to R4 to R5.
E.
If RIPv2 is the routing protocol, the path will be from R1 to R5.
First we need to know the speed of these links:
+ T1: 1.544 Mbps
+ 10BaseT: 10 Mbps
+ 100BaseT (often referred to as FastEthernet): 100Mbps
OSPF chooses the best path via bandwidth while RIP only uses hop count (the sum of routers to reach the destination).
Therefore if OSPF is used, it will choose the path R1 -> R3 -> R4 -> R5 because these links have much higher speed than other paths -> A is correct.
But if RIP is used it only counts the number of routers to reach the destination (the less the better) so it will choose path R1 -> R5 (hop count: 1) -> E is correct.
