A Cisco ACI leaf node has received a Layer 2 frame from an unknown endpoint. The bridge domain is configured for Hardware Proxy. Which action will the ACI fabric take on the traffic?

The correct answer is C. The leaf will forward the traffic to a spine. If the spine has no information in the COOP database,. When a Cisco ACI bridge domain is configured for Hardware Proxy mode, the leaf node does not flood unknown Layer 2 frames within the bridge domain. Instead, the leaf sends the frame to a spine node. The spine node checks its COOP (Council of Oracles Protocol) database to determin

Explanation

When a Cisco ACI bridge domain is configured for Hardware Proxy mode, the leaf node does not flood unknown Layer 2 frames within the bridge domain. Instead, the leaf sends the frame to a spine node. The spine node checks its COOP (Council of Oracles Protocol) database to determine the endpoint location. If the COOP database does not have information about the endpoint, the spine node drops the traffic, as flooding is not allowed in Hardware Proxy mode. This behavior optimizes network traffic by reducing unnecessary flooding.
