You have recently installed a second Routing Engine (RE) in your router
Which two statements correctly describe the expected behavior if the primary RE fails?
The backup RE will assume the master role once the packet forwarding engine restarts
The backup RE will immediately assume the master role
The new master RE restarts the routing protocol process (rpd) and establishes any required adjacencies based on the configuration.
The new master RE maintains the existing protocol adjacencies initially established by the previous master RE
The result depends on the configured features. Reference: http://www.juniper.net/techpubs/en_US/junos9.5/information-products/topic- collections/swconfig-high-availability/high-availability-features-in-junos-introducing.html
