Implementing Cisco ACI Advanced (DCACIA) — Question 27

What are two characteristics of Cisco ACI and Spanning Tree Protocol interaction? (Choose two.)

Answer options

• A. When a TCN BPDU is received in a VLAN, Cisco ACI flushes the endpoints for the associated encapsulation.
• B. STP BPDUs are dropped due to MCP.
• C. MST BPDUs are flooded correctly in Cisco ACI fabric without additional configuration.
• D. BPDU filter and BPDU guard can be configured on Cisco ACI leaf edge ports.
• E. Cisco ACI must be configured as the STP root for all VLANs.

Correct answer: D, E

Explanation

Option D is correct because BPDU filter and BPDU guard can indeed be applied to Cisco ACI leaf edge ports to manage BPDU traffic effectively. Option E is also correct as Cisco ACI must be configured as the STP root for all VLANs to ensure proper traffic management. The other options either misrepresent the behavior of Cisco ACI with STP or describe features that are not applicable.
