JN0-363 Exam Topic 2 Question 34 Discussion:
Question #: 34
Topic #: 2
You want to enable a routing platform with redundant REs to switch from a primary RE to a backup RE without alerting peer nodes. Which two technologies would you use to satisfy this requirement? (Choose two.)
Graceful Routing Engine Switchover (GRES) and Nonstop Active Routing (NSR) are two features used in Junos OS to provide high availability. GRES allows for the stateful failover of the Routing Engine, and NSR allows for the continuation of packet forwarding and protocol states during a Routing Engine switchover. These technologies ensure that peer nodes are not alerted during a switchover. VRRP and ISSU serve different purposes and do not apply to this specific requirement.
