A network engineer is troubleshooting a performance issue on a Junos router. High-throughput transit traffic is being forwarded, and the Routing Engine's CPU utilization is very low. What is the most likely reason for this?

The PFE is handling the transit traffic using the forwarding table and ASICs, offloading the RE.

The RE is using hardware acceleration to process the transit traffic efficiently.

The transit traffic is being dropped because the RE cannot handle the volume.

The PFE is sending all transit traffic to the RE for route lookup, but the RE is fast enough.

What information does the route lookup provide for a transit packet?

The next hop and egress interface

The CoS classification of the packet

The input firewall filter to apply

The source MAC address of the packet

A Junos router is experiencing high CPU utilization on the Routing Engine. The engineer suspects that transit traffic is being processed by the RE instead of the PFE. Which configuration or condition would cause transit traffic to be processed by the RE?

A firewall filter with a 'then accept' action that also sends the packet to the RE

The routing table is not synchronized with the forwarding table.

The PFE is overloaded and cannot handle the traffic volume.

The transit traffic is destined to a locally configured IP address.

What is the purpose of encapsulation during egress processing?

To prepare the packet for transmission on the egress interface

To apply an input firewall filter

To determine the next hop for the packet

A network engineer is troubleshooting a connectivity issue between two sites. The path includes multiple Junos routers. The engineer runs a traceroute from the source to the destination and sees that the trace stops at a specific Junos router. What does this indicate?

The traceroute has reached the edge of the network and cannot go further.

The router is not configured to respond to ICMP packets.

The traceroute packets are being dropped at or beyond that router, possibly by a firewall filter or routing issue.

The router is the final destination and is responding to the traceroute.

Transit Traffic Processing JN0-105 Practice Questions (Page 2)

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.
