Question 52

Which statement describes GRES?

    Correct Answer: C

    Graceful Routing Engine Switchover (GRES) is a feature that provides hardware-level high availability. It ensures that there is a seamless switchover to the backup Routing Engine without interrupting existing traffic flows, leveraging the separation between the control plane and the forwarding plane.

Just did a voucher test and the answer "GRES requires NSR to function properly" was wrong

maziarOption: C

Graceful Routing Engine Switchover (GRES) takes advantage of the separation between the control and forwarding in JUNOS software to provide system redundancy. GRES allows the control plane, in this case the RE, to switch over to its backup RE without any interruption to the existing traffic flows in the PFE.
