Question # 5

An application team tells the Cisco ACI network administrator that it wants to monitor the statistics of the unicast and BUM traffic that are seen in a certain EPG. Which statement describes the collection statistics?

C.

Configure a lower order policy group that enables Cisco Discovery Protocol for the interface on the desired leaf switch.

D.

Create an interface profile for the interface that disables LLDP on the desired switch that is referenced by the interface policy group.

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.

B.

Create an Override Policy with NTP Out-of-Band for leaf and spine switches.

C.
