JNCIA-Junos: Juniper Networks Certified Associate – Junos (2024) — Question 32

Your router has a route to the 10.1.1.0/24 network with a next hop of rjct.
In this scenario, which action will your router perform when traffic destined to the 10.1.1.0/24 network is received?

Answer options

• A. The traffic will be discarded and an ICMP unreachable message will be sent to the destination of the traffic.
• B. The traffic will be silently discarded.
• C. The traffic will be redirected using a default route.
• D. The traffic will be discarded and an ICMP unreachable message will be sent to the source of the traffic.

Correct answer: D

Explanation

When the router receives traffic for the 10.1.1.0/24 network but has a next hop of rjct, it cannot forward the traffic. Therefore, it discards the traffic and sends an ICMP unreachable message back to the source of the traffic, which is why D is correct. The other options do not accurately reflect the behavior of the router in this scenario.
