Implementing Cisco ACI Advanced (DCACIA) — Question 12

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. Enable subinterfaces with dot1q tagging on all links between the IPN routers.
• B. Configure IGMPv3 on the interfaces of IPN routers that face the Cisco ACI spine.
• 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: C

Explanation

Enabling DHCP relay on all links connected to Cisco ACI spines is necessary for new nodes to obtain IP addresses and be discoverable by existing Cisco APICs. The other options do not facilitate the necessary IP address assignments for the new nodes, making them ineffective in this scenario.
