Topic #: 6
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.)
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.
To ensure that Cisco ACI flushes the appropriate endpoints when a topology change notification message is received in an MST domain, the three steps required are:
Enable the BPDU interface controls under the spanning tree interface policy (Option A)2.
Bind the spanning tree policy to the switch policy group (Option C)3.
Associate the STP interface policy to the appropriate interface policy group (Option D)3. These steps ensure that the ACI fabric responds correctly to STP events, such as topology changes, by flushing the MAC address table and the Local Station Table for the affected VLAN on the leaf switch4.
