Designing Cisco Data Center Infrastructure (DCID) — Question 156

A network engineer needs to configure a high availability feature for a data center that uses a Cisco Nexus 7700 Series Switch that is configured with dual supervisors. The feature must meet these requirements:

• Network resilience must be ensured
• Network instability for Layer 3 external routing protocols must be reduced
• Neighbors must be notified when the control plane is restarting
• Traffic must still be forwarded to peers while neighbor relationships are restarting

What should be used to meet these requirements?

Answer options

Correct answer: C

Explanation

NSF (Non-Stop Forwarding) is the correct choice as it allows for the forwarding of traffic to continue while neighbor relationships are being re-established after a control plane restart. This meets the criteria of minimizing network instability for Layer 3 protocols and ensuring network resilience. The other options, while related to high availability, do not provide the same level of support for uninterrupted traffic forwarding during these events.
