Correct Answer: A
Question 4:
What is the purpose of the Forwarding Tag (FTAG) in Cisco ACI?
A. FTAG is used in Cisco ACI to add a label to the iVXLAN traffic in the fabric to apply the correct policy.
B. FTAG is used in Cisco ACI to add a label to the VXLAN traffic in the fabric to apply the correct policy.
C. FTAG trees in Cisco ACI are used to load balance unicast traffic.
D. FTAG trees in Cisco ACI are used to load balance multi-destination traffic.
Correct Answer: D
