What is the purpose of rate limiting exception traffic in Junos?

To ensure that all exception traffic is forwarded to the destination

To prioritize exception traffic over normal traffic

To increase the forwarding rate of exception traffic

To protect the Routing Engine from being overwhelmed by excessive exception traffic

What is the purpose of a loopback filter in Junos?

To manage traffic destined to the Routing Engine

To filter traffic on physical interfaces only

To filter traffic that is forwarded between interfaces

To filter traffic that is sourced from the Routing Engine

A network engineer is designing a high-availability router that must handle a large volume of fragmented packets. The engineer is concerned that the Routing Engine CPU will be overwhelmed by the reassembly process. Which strategy would best mitigate this risk while maintaining forwarding performance?

Apply a firewall filter to drop all fragmented packets.

Enable hardware-based fragmentation reassembly on the Packet Forwarding Engine.

Increase the Routing Engine's priority in the scheduler.

Use a policer to rate-limit fragmented packets to the Routing Engine.

How does the Packet Forwarding Engine (PFE) handle packets that require exception processing?

It forwards them normally and ignores any special requirements

It drops them immediately to protect the device

It stores them in a buffer until the network is idle

It queues them and sends them to the Routing Engine for processing
