Explanation

PAN-OS uses longest-prefix-match (most specific route) to determine the forwarding path. Among all routes shown in the referenced routing table image, Route 2 contains the most specific prefix that encompasses 10.10.0.4. When multiple routes could match a destination, the route with the longest (most specific) subnet mask always wins. If two routes share the same prefix length, administrative distance and then metric are used as tiebreakers - but in this case, Route 2 wins on prefix specificity alone.
