C. CoS can prioritize latency-sensitive traffic

D. CoS can increase network bandwidth.

Correct Answer: BC

Ref: Benefits of CoS | Junos OS | Juniper Networks

“Benefits of CoS

…

CoS features allow a Juniper Networks device to improve its processing of critical packets while maintaining best-effort traffic flows, even during periods of congestion.

…

CoS dedicates a guaranteed minimum bandwidth to a particular service class by reducing forwarding queue delays.

D. It lists tips for the help menu.

Correct Answer: BC

Question 8:

Click the Exhibit button.

Referring to the exhibit, OSPF has three export policies that match different static route prefixes. The 10.10.10.0/24 static route does not match any terms in the policy1 routing policy.

What happens next in this scenario?

A. The static route is rejected by the default routing policy.

B. The static route is rejected by the policy1 routing policy.

C. The static route is evaluated by the policy2 routing policy.

Which two statements describe the RE on Junos OS devices? (Choose two.)

A. The RE is considered the control plane.

B. The RE forwards traffic based on its local copy of the forwarding table.

C. The RE provides hardware status messages for the PFE

D. The RE maintains the routing tables.

Correct Answer: AD

Ref: Juniper Networks Partner Solution Development Platform: Architecture of the JUNOS System

“Architecture of the JUNOS System

…

The Routing Engine operates all routing protocols and makes all routing decisions by creating a routing table that includes the best path to each destination. The router writes these paths to a forwarding table in the Routing Engine and then

copies the same data to the forwarding table on the Packet Forwarding Engine (PFE) which actually forwards the packets.

…

The Control Plane

…

The control plane runs on the Routing Engine. Its role is to manage and control the behavior of the device, including the data plane and the services plane.

…”
