How does nonstop bridging (NSB) maintain seamless operation during a Routing Engine failover?

By continuously synchronizing the bridging table and STP state to the standby Routing Engine

By using a separate hardware switch fabric to handle failover

By restarting the bridging process on the active Routing Engine

By flooding all traffic to all interfaces during failover

What is the primary purpose of nonstop bridging (NSB) on Juniper devices?

To provide faster convergence for OSPF and IS-IS routing protocols

To enable hitless upgrade of the Junos OS software

To maintain Layer 2 forwarding and control plane state across a Routing Engine failover

To synchronize firewall filter configurations between Routing Engines

Which of the following is a limitation of nonstop bridging (NSB)?

It cannot be used with virtual chassis configurations

It is only supported on devices with dual Routing Engines

It requires a separate license for each VLAN

It can only be used with OSPF as the routing protocol

A service provider is planning to deploy nonstop bridging (NSB) on a new line of routers. The network architect has been asked to identify the key requirement that must be met for NSB to function correctly. Which requirement is mandatory for NSB to operate?

The device must run BGP with graceful restart enabled

The device must have two Routing Engines

The device must be configured as a route reflector

The device must be a virtual chassis with multiple member switches
