Implementing Cisco ACI Advanced (DCACIA) — Question 29

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

Option C is correct because the mis-cabling protocol indeed helps in monitoring MSTP TCN packets. Option D is also correct as it is essential to have a dedicated EPG for the native VLAN ID with static bindings to ensure proper interaction with MSTP-enabled switches. The other options are inaccurate or do not reflect the required characteristics of Cisco ACI with MSTP.
