    Correct Answer: C

    Routes are chosen based on the longest prefix match principle. Multiple routes have the destination prefix 10.10.0.0/24, including Route 1 and Route 2. When there are routes with equal prefix lengths, the route with the lower metric is preferred. Both Route 1 and Route 2 have the same destination prefix, but Route 2 has a lower metric of 20 compared to Route 1's metric of 30. Thus, Route 2 is selected for destination 10.10.0.4.

Discussion
PakawatOption: C

Prefer route 2 with lowest metric

secdaddy

longest match. lowest metric only comes into play if there is more than one route with the same length match.

JheaxOption: C

This is the line that you want to pay attention to answer this question: set network virtual-router 2 routing-table ip static-route "Route 2" destination 10.10.0.0/24

WhizdhumOption: C

Answer is C. It would be easier to format the configuration line-by-line, so that the four options are shown clearly. Nevertheless, I was able to sift through the jumbled configuration and find the answer.

Knowledge33Option: C

Longuest mask first, then lowest metric is longuest mask is concurrent.

mbhuyanOption: C

Opps my bed..the answer is C... longest has the different destination which is 10.10.1.0/25 I thought its 10.10.0.0/25.

mbhuyanOption: D

Longest match is 10.10.0.4 /25 which has the higher priority than /24. So the answer is D, not C

hcir

mate, 10.10.1.0/25 matches 10.10.1.(0-127)

djedeenOption: B

Route 3 has the lowest metric, but 1 & 2 are longer match than its 0.0.0.0/0 destination.
