• Question 375:

  On a Junos device with dual Routing Engine (RE), which two statements correctly describe the expected behavior if the primary RE fails? (Choose two.)

  A. The backup RE will assume the master role once the packet forwarding engine (PFE) restarts
  B. The backup RE will immediately assume the master role
  C. The new master RE restarts the routing protocol process (rpd) and establishes any required adjacencies based on the configuration.
