A neighboring router is performing a graceful restart of BGP. Your Juniper router is acting as a helper. What is the maximum time your router will wait for the neighbor to come back before tearing down the session?

The restart time advertised by the neighbor in the BGP OPEN message.

The stale route timeout configured on the helper router.

The time configured in the graceful-restart configuration on the helper router.

The default BGP hold time of 90 seconds.

What is the role of a Junos device acting in helper mode during a neighbor's graceful restart?

It immediately tears down all adjacencies with the restarting neighbor

It sends a notification to the network management system about the neighbor's restart

It takes over the routing responsibilities of the restarting neighbor

It continues to advertise routes and forwards traffic as if the neighbor is still fully operational

What is the primary purpose of graceful restart in Junos?

To enable the forwarding table to be rebuilt from scratch after a reboot

To synchronize the routing table between two Routing Engines continuously

To provide a backup Routing Engine that takes over immediately if the active one fails

To allow a routing protocol process to restart without causing neighboring routers to recalculate routes
