In a Junos device, which component is responsible for maintaining the routing table and making control-plane decisions, while the other component handles the actual forwarding of packets?

Both the Routing Engine and the Packet Forwarding Engine perform identical functions and share the forwarding load equally.

The Routing Engine forwards packets, and the Packet Forwarding Engine only stores the routing table.

The Routing Engine performs control-plane functions, and the Packet Forwarding Engine handles data-plane forwarding.

The Packet Forwarding Engine runs routing protocols, and the Routing Engine forwards packets.

A network engineer is troubleshooting a Junos device that is not forwarding traffic as expected. The engineer suspects the issue may be related to the control plane. Which statement correctly describes the role of the Routing Engine in packet forwarding?

The Routing Engine only handles exception traffic and does not participate in route learning.

The Routing Engine performs the actual packet forwarding at line rate using specialized hardware.

The Routing Engine builds and maintains the routing table and programs the forwarding table used by the Packet Forwarding Engine.

The Routing Engine inspects each packet's header and makes forwarding decisions for every packet.

What is filter-based forwarding (FBF) used for in Junos?

To forward packets based on criteria other than the destination IP address

To block all traffic from a specific source

To prioritize traffic based on QoS

To filter packets based on the destination IP address only

A Junos router has two equal-cost paths to a destination. The network administrator wants to ensure that all packets of a given TCP session use the same path, but different sessions can use different paths. Which configuration should be used?

Enable per-packet load balancing.

Configure a firewall filter to alternate paths per packet.

Use a routing policy to select the path based on the source port.

Enable per-flow load balancing using the default hash algorithm.

A Junos router has two equal-cost BGP paths to a destination. Load balancing is enabled. How does Junos typically distribute traffic across these paths?

It uses the path with the lowest IP address for all traffic.

It sends packets in a round-robin fashion, one packet per path.

It hashes the packet's header fields to select a path for each flow.

It alternates paths based on the source MAC address.
