300-630 practice question 9 of 25

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. Correct answer

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. Correct answer

E: The PVST simulation must be configured on external network switches to support MSTP.

Correct Answer:

A. A Cisco ACI leaf flushes all local endpoints in the received EPG when an MSTP TCN frame is received.; D. A dedicated EPG must be created for the native VLAN ID with static bindings toward the MSTP- enabled switches.

Explanation

Cisco ACI handles MSTP TCN frames by flushing local endpoints in the affected EPG to prevent stale entries. For MST BPDUs to traverse the ACI fabric, a dedicated EPG for the native VLAN with static bindings is required for MSTP-enabled external switches.
