Implementing Cisco Application Centric Infrastructure (DCACI) — Question 12

When Cisco ACI connects to an outside Layers 2 network, where does the ACI fabric flood the STP BPDU frame?

Answer options

• A. within the bridge domain
• B. within the APIC
• C. within the access encap VLAN
• D. between all the spine and leaf switches

Correct answer: C

Explanation

The correct answer is C because the ACI fabric floods STP BPDUs within the access encapsulation VLAN to ensure that the external Layer 2 network receives the necessary spanning tree information. The other options are incorrect as the bridge domain is not where BPDUs are flooded, the APIC does not handle BPDU flooding, and flooding does not occur between all spine and leaf switches in this context.
