A service provider is evaluating nonstop bridging (NSB) for its core network to improve high availability. The network carries critical Layer 2 services, and the provider wants to minimize the impact of a Routing Engine failover on these services. Which benefit does NSB provide in this scenario?

It prevents any packet loss during a Routing Engine failover

It preserves the Layer 2 forwarding table during a Routing Engine failover

It eliminates the need for redundant Routing Engines

It automatically restarts failed routing protocols

Which benefit does nonstop bridging (NSB) provide in a high-availability network?

It provides encryption for Layer 2 traffic between switches

It automatically reroutes traffic to a different VLAN during congestion

It reduces the impact of a Routing Engine failover on Layer 2 forwarding

It eliminates the need for redundant links in the network

A service provider is planning to deploy nonstop bridging (NSB) on a new core router to support Layer 2 VPN services. The network architect has been asked to evaluate the benefits and limitations of NSB in this context. The architect is concerned about the impact of NSB on the Layer 2 VPN forwarding state. Which statement accurately describes the behavior of NSB for Layer 2 VPNs?

NSB will cause the Layer 2 VPN to flap during a failover

NSB preserves the Layer 2 VPN forwarding table, including MAC addresses, during a failover

NSB does not support Layer 2 VPNs; it only works for simple bridging

NSB requires the Layer 2 VPN to be configured with a specific routing instance type

Which CLI command enables nonstop bridging (NSB) on a Juniper device?

set chassis redundancy graceful-switchover

Which feature, when used with NSB, can cause unexpected behavior and should be carefully evaluated?

Graceful Routing Engine switchover (GRES)

Nonstop Bridging (NSB) JN0-364 Practice Questions (Page 2)

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 16 practice questions to prepare you well beyond it.
