Implementing Cisco Enterprise Advanced Routing and Services (ENARSI) — Question 204

An engineer must override the normal routing behavior of a router for Telnet traffic that is destined to 10.10.10.10 from 10.10.1.0/24 via a next hop of 10.4.4.4, which is directly connected to the router that is connected to the 10.1.1.0/24 subnet. Which configuration reroutes traffic according to this requirement?

Answer options

• A. access-list 100 deny tcp 10.10.1.0 0.0.0.255 host 10.10.10.10 eq 23 ! route-map POLICY permit 10 match ip address 100 set ip next-hop 10.4.4.4 route-map POLICY permit 20
• B. access-list 100 permit tcp 10.10.1.0 0.0.0.255 host 10.10.10.10 eq 23 ! route-map POLICY permit 10 match ip address 100 set ip next-hop 10.4.4.4 route-map POLICY permit 20
• C. access-list 100 permit tcp 10.10.1.0 0.0.0.255 host 10.10.10.10 eq 23 ! route-map POLICY permit 10 match ip address 100 set ip next-hop recursive 10.4.4.4 route-map POLICY permit 20
• D. access-list 100 permit tcp 10.10.1.0 0.0.0.255 host 10.10.10.10 eq 23 ! route-map POLICY permit 10 match ip address 100 set ip next-hop recursive 10.4.4.4

Correct answer: D

Explanation

The correct answer is D because it properly permits Telnet traffic and uses a recursive next-hop, ensuring that the router can determine the next hop's route. Option A incorrectly denies the traffic, while option B uses a direct next-hop instead of recursive, which may not work if the next hop is not directly reachable. Option C also uses a recursive next-hop but does not fulfill the requirement as effectively as D.
