Question 1

A situation causes a fault to be raised on the APIC. The ACI administrator does not want that fault to be raised because it is not directly relevant to the environment. Which action should the administrator take to prevent the fault from appearing?

A. Create a stats threshold policy with both rising and falling thresholds defined so that the critical severity threshold matches the squelched threshold.

B. Create a new global health score policy that ignores specific faults as identified by their unique fault code.

C. Under System -> Faults, right-click on the fault and select Acknowledge Fault so that acknowledged faults will immediately disappear.

D. Under System -> Faults, right-click on the fault and select Ignore Fault to create a fault severity assignment policy that hides the fault.

Question 2

In a Cisco ACI fabric, an endpoint moves between two leaf switches during a virtual machine migration. Which action does Cisco ACI take to minimize the impact to traffic during this event?

A. A new leaf switch sends a COOP message to the Cisco APIC cluster to populate a new location of the endpoint.

B. A new leaf switch updates a COOP database on the spine, which causes the old leaf switch to install a bounce entry.

C. A new leaf switch floods GARP to every other leaf switch in the fabric, which advertises a new endpoint location to the fabric.

D. A new leaf switch sends a COOP message directly to the old leaf switch to update it with new information about the endpoint move.

Question 3

Refer to the exhibit. The EPG-100 must be extended to the vCenter as a port group with a tagged VLAN ID of 100. Which set of actions accomplishes this goal?

A. Define a dynamic VLAN range (from 100-200) under a VLAN pool that is associated with the dc1vdev domain.

VLAN Mode: Static with Encap: 100

D. Define a static VLAN range (from 100-200) under a VLAN pool that is associated with the dc1vcdev domain.
Associate the dc1vcdev domain with EPG and select these settings:
Untagged VLAN Access: unselected
VLAN Mode: Static with Encap: 100
