A network administrator is configuring a router that must handle a mix of exception traffic types, including control plane traffic (e.g., OSPF hellos), fragmented packets, and packets requiring services. The administrator wants to ensure that control plane traffic is not starved by other exception traffic. Which configuration should be used?

Use a policer to rate-limit all exception traffic equally.

Apply a firewall filter to the loopback interface that prioritizes control plane traffic and rate-limits other exception traffic.

Disable all services that generate exception traffic.

Increase the Routing Engine's priority in the scheduler.

Which mechanism is used to limit the rate of exception traffic to protect the Routing Engine?

Disabling the Routing Engine's processing of exception traffic

Rate limiting or policing applied to exception traffic

Firewall filters that drop all exception traffic

Increasing the buffer size on the Packet Forwarding Engine

In Junos packet processing, what is the primary role of exception traffic?

To be forwarded at line rate through the Packet Forwarding Engine without any special handling

To be processed by the Routing Engine because it requires additional handling beyond standard forwarding

To be encapsulated and tunneled to a remote device for analysis

To be dropped immediately by the Packet Forwarding Engine to protect the network

Which interface is commonly used to apply a filter to protect the Routing Engine?

The management interface (e.g., fxp0)

The internal interface between the PFE and RE

The physical interface that connects to the internet

A network administrator is troubleshooting a router that is experiencing intermittent connectivity issues. The administrator suspects that the Routing Engine is being overwhelmed by exception traffic. Which command would help confirm this by showing the rate of exception traffic?
