What is the primary purpose of unicast Reverse-Path-Forwarding (RPF) on a Junos device?

To ensure that the destination address of an outgoing packet is reachable via the forwarding table

To verify that the source address of an incoming packet is reachable via the interface on which it was received

To encrypt packets that originate from a source address not in the forwarding table

To prioritize traffic based on the source address of incoming packets

Which Junos configuration method is used to enable unicast RPF on an interface?

Enabling 'ip verify unicast source reachable-via' under the interface

Applying a firewall filter with the 'rpf-check' action to the interface

Setting the 'reverse-path' statement under the interface's family inet

Adding the 'rpf' statement to the routing policy options

Your security team wants to deploy RPF on all edge routers to mitigate spoofing attacks. The network uses OSPF internally and has a default route to the internet. Some internal links are redundant, and traffic may occasionally take a different return path. Which RPF mode should you recommend for the internal interfaces?

Strict mode on the internet-facing interface and loose mode on internal interfaces

Loose mode on all internal interfaces

No RPF on internal interfaces because OSPF prevents spoofing

Strict mode on all internal interfaces

Unicast Reverse-Path-Forwarding (RPF) JN0-105 Practice Questions (Page 2)

Part of the Routing Policy and Firewall Filters domain, which makes up ~11% of our current practice bank. Juniper Networks does not publish an official question count, but from its 90-minute exam (~35–60 total, ~4–7 in this domain), expect 1–1 from this objective — we provide 15 practice questions to prepare you well beyond it.
