What does the traceroute utility primarily show you?

The path that packets take from source to destination

The CPU utilization of each router

The bandwidth of each link along the path

The firewall filters applied on each router

How does the PFE obtain the forwarding table it uses to forward transit traffic?

The Routing Engine installs it into the PFE

It builds the table from routing protocol updates it receives directly

It is manually configured by the network administrator

It is downloaded from a central controller

A Junos router receives a transit packet. The PFE performs a route lookup and finds multiple equal-cost paths to the destination. What does the PFE do in this scenario?

It load-balances the traffic across the equal-cost paths.

It drops the packet because multiple paths create ambiguity.

It sends the packet to the Routing Engine to make the forwarding decision.

It selects the path with the lowest metric and uses it exclusively.

What is the primary role of the Packet Forwarding Engine (PFE) in the transit traffic path?

To apply security policies that filter transit traffic

To forward packets from the ingress interface to the egress interface based on the forwarding table

To terminate packets destined to the device itself

To run routing protocols and build the routing table

Transit Traffic Processing JN0-105 Practice Questions (Page 4)

Part of the Junos OS Fundamentals domain, which makes up ~14% of our current practice bank. Juniper Networks does not publish an official question count, but from its 90-minute exam (~35–60 total, ~5–8 in this domain), expect 1–2 from this objective — we provide 24 practice questions to prepare you well beyond it.
