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

  1. The RE is considered the control plane.
  2. The RE forwards traffic based on its local copy of the forwarding table.
  3. The RE provides hardware status messages for the PFE
  4. The RE maintains the routing tables.

Answer(s): A,D

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.

Which command allows multiple users to edit a configuration while conning only their unique changes?

  1. configure exclusive
  2. configure batch
  3. configure private
  4. configure dynamic

Answer(s): C

Explanation:

The configure private command allows multiple users to edit different parts of a configuration at the same time and commit only their changes or roll back, without interfering with each other's changes.
When the configure private command is used, you work in a private candidate configuration, which is a copy of the most recently committed configuration.
