In graceful restart, what is the role of the helper router?

It continues to advertise routes and forward traffic on behalf of the restarting router

It stores a backup of the restarting router's configuration

It initiates the restart and rebuilds its routing table

It immediately tears down the adjacency to force a new convergence

What is the purpose of RSVP graceful restart?

To provide a backup RSVP session in case the primary session fails

To reduce the number of RSVP messages sent between neighbors

To allow RSVP to use a different transport protocol during a restart

To preserve MPLS LSPs and their associated RSVP state during a control plane restart

A service provider is deploying RSVP graceful restart on its MPLS core. The provider wants to ensure that during a router restart, RSVP sessions and label-switched paths (LSPs) are not disrupted. What is the primary mechanism that allows RSVP neighbors to maintain LSP state during a restart?

RSVP hello extension with restart capabilities

During BGP graceful restart, what happens to routes learned from a restarting peer?

They are marked as stale and kept in the routing table for a period

They are flushed and re-learned from other peers

They are immediately removed from the routing table

They are moved to a backup routing table

An ISP is deploying IS-IS graceful restart on its core routers. The network uses a mix of vendor equipment, and the ISP wants to ensure that a restarting router can signal its restart to neighbors that may not support the full IS-IS graceful restart extension. What mechanism in IS-IS allows the restarting router to indicate that it is restarting and request help from neighbors?

The Restart TLV in IS-IS hello PDUs

The IS-IS sequence number PDU (SNP)

The IS-IS complete sequence number PDU (CSNP)

Graceful Restart (GR) JN0-364 Practice Questions (Page 1)

Part of the High Availability domain, which makes up ~12% of our current practice bank. Juniper Networks does not publish an official question count, but from its 90-minute exam (~35–60 total, ~4–7 in this domain), expect 1–1 from this objective — we provide 21 practice questions to prepare you well beyond it.
