The correct answer is D. The system is NSR ready and a switchover should be hitless to the BGP control and data plane. See the full explanation below for the reasoning.

Options

  • AAn RE switchover is likely to result in BGP disruption, but no dataplane impact will be seen.
  • BAn RE switchover is likely to result in BGP disruption which will also effect the dataplane.
  • CThe system is not yet GRES ready, you need to wait for kernel synchronization to complete.
  • DThe system is NSR ready and a switchover should be hitless to the BGP control and data plane.
