Exam JN0-105 topic 1 question 33 discussion

In this scenario, the router has a route to the 10.1.1.0/24 network, but the next hop is labeled as rjct, which suggests that the next hop is rejected or invalid. When a router has a route with an invalid next hop, it cannot forward the traffic to the destination network. The typical behavior in this case is: 1. The router will discard the traffic because it cannot forward it to the invalid next hop. 2. The router will then send an ICMP unreachable message to the source of the traffic (not the destination). This message informs the source that the network is unreachable.

Answer should be D as icmp packet will be discarded

Default When an aggregate route becomes active, it is installed in the routing table with a reject next hop, which means that ICMP unreachable messages are sent.

the answer is D

b In a scenario where a router has a route to a specific network (in this case, 10.1.1.0/24) with a next hop that is unreachable or incorrectly specified (e.g., "r jet" seems to be a typo or an undefined entity), the router will typically discard the traffic destined for that network. This action is taken because the router cannot determine a valid path to forward the traffic. Unlike some scenarios where the router might generate an ICMP (Internet Control Message Protocol) unreachable message, in many configurations, especially in production networks, the traffic might be silently discarded without providing feedback to the sender, as generating ICMP messages for all undeliverable packets could lead to additional network congestion and potential security concerns.

D is correct answer.
