Which ACL and route-map configuration forces HTTP traffic from 10.1.1.0/24 to destination 10.100.100.100 to use next hop 10.2.2.2 (recursive, two hops away)?

Correct answer: access-list 100 permit tcp 10.1.1.0 0.0.0.255 host 10.100.100.100 eq http; route-map POLICY permit 10 match ip address 100 set ip next-hop recursive 10.2.2.2.
Why this is the answer
The correct option uses set ip next-hop recursive 10.2.2.2. The recursive keyword is crucial because the next hop 10.2.2.2 is "two hops away," meaning the router needs to perform a recursive lookup to find the exit interface for 10.2.2.2. Without recursive, the router would only attempt a direct lookup for 10.2.2.2, which would fail if 10.2.2.2 is not directly connected. The ACL correctly identifies the HTTP traffic from the source network to the specific destination host. The incorrect options either omit the recursive keyword, which is necessary for a non-directly connected next hop, or use deny in the route-map, which would prevent the policy from being applied to the matched traffic. A deny statement in a route-map means that traffic matching the criteria will not be processed by that route-map entry, and if no subsequent permit entry matches, the traffic will be forwarded normally based on the routing table.
