CCDE Practical Exam — Question 31

What are two characteristics of Cisco ACI interaction with MSTP? (Choose two.)

Answer options

• A. A Cisco ACI leaf flushes all local endpoints in the received EPG when an MSTP TCN frame is received.
• B. A static path binding is required for native VLAN to carry the MST BPDUs in existing EPGs.
• C. Mis-cabling protocol is used to snoop the MSTP TCN packets.
• D. A dedicated EPG must be created for the native VLAN ID with static bindings toward the MSTP-enabled switches.
• E. The PVST simulation must be configured on external network switches to support MSTP.

Correct answer: C, D

Explanation

The correct answers are C and D because the mis-cabling protocol indeed monitors MSTP TCN packets, and a dedicated EPG is required for the native VLAN ID with static bindings to work with MSTP-enabled switches. Options A and B are incorrect as they misrepresent the interaction between Cisco ACI and MSTP, and option E is irrelevant to the specific question about ACI interaction.
