Actual exam question from Cisco's 200-301

Question #: 463
Topic #: 1

Refer to the exhibit. Router R1 currently is configured to use R3 as the primary route to the internet, and the route uses the default administrative distance settings. A network engineer must configure R1 so that it uses R2 as a backup, but only if R3 goes down. Which command must the engineer configure on R1 so that it correctly uses R2 as a backup route, without changing the administrative distance configuration on the link to R3?

A. ip route 0.0.0.0 0.0.0.0 209.165.201.5.10
B. ip route 0.0.0.0 0.0.0.0 g0/1 1
C. ip route 0.0.0.0 0.0.0.0 209.165.200.226 1
D. ip route 0.0.0.0 0.0.0.0 g0/1 6

Selected Answer: D

Important thing to take note of is, the syntax for creating a default static route or connected static route uses the exit interface or output interface of source device (that’s the interface on which all packets are sent to the destination network). Some of us may confuse and think to use Gi0/0 interface on R3 in the command, but the interface to configure the backup route here must use the exit interface on the R1 itself i.e. Gi0/1. So command will be: ip route 0.0.0.0 0.0.0.0 g0/1 6 ("6" here is AD that's greater than the connected route's AD i.e., 1)

The main culprit in this question is the AD of 6. We are not told what type of connection is between R1 and R3 which is in and of itself ridiculous. Now that we know we have to assume from there, AD is probably 1, in which case we have to pick an answer with the correct syntax that has a higher AD. This only leaves D. Once again, poorly written question.

I though this ip route 0.0.0.0 0.0.0.0 g0/1 6 was this ip route 0.0.0.0 0.0.0.0 g0/16, normally couldn't find the 16th port... :)

"D" es correcto. Porque la AD por defecto es "1". Por lo tanto quien tiene el AD mas alto es "D" en este caso es "6". De esta forma queda configurada la ruta de respaldo
