JNCIA-Junos: Juniper Networks Certified Associate – Junos (2022) — Question 80

You enable unicast reverse path forwarding on the ge-0/0/1.0 interface A packet is received on the ge-0/0/1.0 interface with a source address of 10.10.10.10. A route lookup determines that the next hop for the 10.10.10.10 address is the ge-0/0/1.0 interface. In this scenario which action is performed?

Answer options

• A. The packet is logged
• B. The packet is forwarded
• C. The packet is rejected
• D. The packet is discarded

Correct answer: B

Explanation

The correct answer is B because when unicast reverse path forwarding is enabled and the source address matches the expected interface, the packet is allowed to be forwarded. Options A, C, and D are incorrect because they describe actions that do not occur in this scenario; the packet is not logged, rejected, or discarded since it has passed the reverse path check.
