Implementing Cisco Application Centric Infrastructure (DCACI) — Question 201

A Cisco ACI leaf switch learns the source IP address of a packet that enters the front panel port of the switch. Which bridge domain setting is used?

Answer options

• A. ARP Flooding
• B. L3 Unknown Multicast Flooding - Flood
• C. L2 Unknown Unicast - Hardware proxy
• D. Unicast Routing

Correct answer: D

Explanation

The correct answer is D, Unicast Routing, as it allows the switch to learn and route packets based on the source IP address. The other options, while related to different flooding methods, do not specifically address the learning of source IP addresses in the context of unicast traffic.
