QUESTION 16
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.

Answer: AE

Explanation:

OSPF metric for path selection is 100Mbps/(Bandwidth Of the Link) according to this rule lowst cost path is chosen

Option A: R1 to R3 to R4 to R5 = 100Mb/10 Base T + 100Mb/100 Base t + 100Mb/100 Base t
= 10+1+1 =12

Option B: R1 to R2 to R5 = 100Mb/T1 + 100 Mb/T1 =64.766 + 64.766 = 129.532

Option C: R1 to R5 = 100Mb/64k =1562


RIP Will choose path with least HOP's so OPTION E
