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.
  • D. The new master RE maintains the existing protocol adjacencies initially established by the previous master RE

Suggested Answer: AC 🗳️
When a Junos device has redundant RE's but no HA features enabled, and the master RE fails, the PFE restarts and all hardware and interfaces are discovered by the new master RE. The new master RE starts rpd so that all adjacencies are aware fo the topological changes.
