Implementing Cisco ACI Advanced (DCACIA) — Question 45

What is the purpose of the Forwarding Tag (FTAG) in Cisco ACI?

Answer options

• 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 mutli-destination traffic.

Correct answer: D

Explanation

The correct answer is D because FTAG trees are specifically designed to manage and distribute multi-destination traffic effectively in Cisco ACI. Options A and B incorrectly refer to the labeling of iVXLAN and VXLAN traffic, which does not pertain to the function of FTAG. Option C misrepresents the functionality of FTAG trees, as they do not focus on unicast traffic.
