Demo Questions
Question 1
Refer to the exhibit. How is the ARP request from VM1 forwarded when VM2 is not learned in the Cisco ACI fabric?
- Leaf 101 forwards the ARP request to one of the proxy VTEP spines.
- POD1 spine responds to the ARP request after the POD1 COOP is updated with the VM2 location.
- Leaf 101 encapsulates the ARP request into a multicast packet that is destined to 225.0.37.192.
- Leaf 101 switch consumers the ARP reply of VM2 to update the local endpoint table.
Correct answer: A
Question 2
Which approach does Cisco ACI use to achieve multidestination packet forwarding between leaf switches in the same fabric?
- Map VXLAN VTEP to the multicast group
- Map VXLAN to PIM-SM protocol
- Map VXLAN VNI to the multicast group
- Map VXLAN to PIM-DM protocol
Correct answer: C
Question 3
What does the VXLAN source port add to the overlay packet forwarding when it uses the hash of Layer 2, Layer 3, and Layer 4 headers of the inner packet?
- ECMP
- TCP optimization
- disabled fragmentation
- jumbo frames
Correct answer: A
