QuestionQ115

Network Design

A network engineer must choose a high-availability feature for a data center. The solution must provide network resilience, reduce instability in Layer 3 routing protocols, and satisfy these requirements:

  • The device must inform its neighbors when the control plane is restarting.
  • The solution must suppress routing flaps during stateful switchovers.

Which solution must be implemented?

  • A BFD
  • B HSRP
  • C NSF
  • D ISSU
Explanation

Cisco Nonstop Forwarding (NSF) works with Stateful Switchover (SSO) to maintain packet forwarding while routing information is restored. Its graceful-restart behavior allows routing neighbors to recognize the restart, and NSF suppresses routing flaps on SSO-enabled devices, reducing network instability.
