Implementing Cisco Application Centric Infrastructure (DCACI) — Question 108

An engineer configures a Cisco ACI Multi-Pod for disaster recovery. Which action should be taken for the new nodes to be discoverable by the existing Cisco APICs?

Answer options

• A. Configure IGMPv3 on the interfaces of IPN routers that face the Cisco ACI spine.
• B. Enable subinterfaces with dot1q tagging on all links between the IPN routers.
• C. Enable DHCP relay on all links that are connected to Cisco ACI spines on IPN devices.
• D. Configure BGP as the underlay protocol in IPN.

Correct answer: A

Explanation

The correct answer is A because configuring IGMPv3 allows the multicast traffic needed for node discovery in a Cisco ACI Multi-Pod environment. The other options, while potentially useful in different contexts, do not directly address the requirement for node discovery in this specific setup.
