   Which benefit does NSR provide that directly improves network stability during a Routing Engine switchover?

   • AIt automatically reroutes traffic around the failed RE to avoid any disruption.
   • BIt ensures that neighboring routers do not detect the switchover, so they do not reset adjacencies or recalculate routes.
   • CIt prevents any packet loss by buffering all traffic in the forwarding plane.
   • DIt provides a redundant data path for all traffic, ensuring zero downtime.

   A service provider is deploying a new core router and wants to ensure that a Routing Engine failure does not cause any disruption to BGP and OSPF traffic. The router has dual REs and the network team is considering whether to use NSR or GRES. Which benefit does NSR provide over GRES in this scenario?

   • ANSR is supported on all Junos platforms, while GRES is not.
   • BNSR preserves the forwarding table during a switchover, while GRES does not.
   • CNSR maintains protocol adjacencies during a switchover, while GRES does not.
   • DNSR requires only one Routing Engine, while GRES requires two.
