CCDE Practical Exam — Question 16

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

Answer D is correct because Cisco ACI allows the configuration of BPDU filter and BPDU guard on leaf edge ports to enhance network stability. Answer E is also correct, as Cisco ACI must be the STP root for all VLANs to manage traffic effectively. Options A, B, and C are incorrect as they do not accurately represent the functionality of Cisco ACI in relation to Spanning Tree Protocol.
