Implementing Cisco Application Centric Infrastructure (DCACI) — Question 97

An engineer must ensure that Cisco ACI flushes the appropriate endpoints when a topology change notification message is received in an MST domain. Which three steps are required to accomplish this goal? (Choose three.)

Answer options

• A. Enable the BPDU interface controls under the spanning tree interface policy.
• B. Configure a new STP interface policy.
• C. Bind the spanning tree policy to the switch policy group.
• D. Associate the STP interface policy to the appropriate interface policy group.
• E. Create a new region policy under the spanning tree policy.
• F. Map VLAN range to MST instance number.

Correct answer: C, E, F

Explanation

The correct answer includes steps that directly relate to configuring the spanning tree policy and its association with the switch policy group and MST region. Options A and B do not directly contribute to flushing the endpoints when a topology change occurs, while option D focuses on interface policy grouping but lacks the necessary link to the spanning tree policy.
